Project aim
This project was conceived to carry out a biological survey of a reserve forming part
of the National Reserve System, to provide biodiversity information for reserve
management and to contribute to taxonomic knowledge including description of new
species as appropriate.
Survey structure
A team of scientists specialising in different organism groups each with a team of
Earthwatch volunteer assistants, driver and vehicle, carried out the survey following
individually devised field programs, over the 1 week period 5-9 May 2009.
Science teams
Five science teams, each led by one of the scientists, specialised on the following
organism groups:
Plants, Insects (Lepidoptera), Insects (Heteroptera), Vertebrates , Arachnids.
Plants were collected by the Plants team and also by some of the animal scientists,
particularly Celia Symonds, in order to accurately document the insect host plants.
These additional collections were identified along with the other flora vouchers, and
contribute to the flora results reported here.
Flora: introduction
The Charles Darwin Reserve consists of a mosaic of plant communities which inhabit
extensive plains of yellow sand, red sandy clay or loam, granite rocks, lateritic
breakways, greenstone ridges or hills, and wetlands such as salt lakes, claypans and
ephemeral swamps. The vegetation includes extensive areas of species-rich shrubland
of several variants that are representative of flora considered characteristic of the
Wheatbelt, Acacia-dominated shrubland on red soil plains, and Eucalyptus woodlands
on heavier clay-containing soils, and these are of different kinds: York Gum (E.
loxophleba) woodland, Salmon Gum ( E. salmonophloia) woodland, and Gimlet (E.
salubris) woodland, and chenopod shrublands on saline sites. The vegetation can be
4
considered as containing significant proportions of types characteristic of the
Wheatbelt and of the arid zone Rangelands.
The Reserve was formerly White Wells pastoral station and was grazed intermittently
by sheep for about 80 years (Nicholson 2007). However the vegetation was not
cleared, except for a relatively small area near the homestead which has been cropped.
Overlaying the mosaic of plant communities is another mosaic, of fire history, and the
age since fire can have as dramatic a visual effect as differences in vegetation type.
Examples are evident in parts of the Reserve now. Recency of fire can also govern the
occurrence of species since some live for only a short time after fire (or physical
disturbance such as track work). The condition of the vegetation and therefore the
success of biological survey work is also affected substantially by the season and the
amount of rain that has fallen in the preceding period.
The vegetation and species of plants occurring in the Charles Darwin Reserve are
moderately well known, but as the results of this survey show, the Reserve has not
been exhaustively surveyed. The list of possibly new taxa also demonstrates that the
Reserve flora is consistent with the general situation in south western Australia, which
is that taxonomic knowledge is far from complete.
Previous collecting has been fairly extensive, and has been carried out by WA
volunteer groups including the WA Wildflower Society and the WA Naturalists Club,
the Agriculture Department Rangelands Survey group (Payne et al. 1998), Bush
Heritage reserve managers, environmental consultants, Department of Environment
and Conservation (DEC) flora officers, and passing botanists. A large proportion of
the records have been made over many years by botanists from throughout Australia
and elsewhere passing along the Great Northern Highway which traverses the south
east corner of the Reserve. A longer stretch of the Highway falls within the buffer
zone used in the preparation of the list and is one reason for the wider WAHERB list
exceeding the Reserve list (see below) by such a large number of species (Map1).
The Survey
Objectives of the flora survey
The flora survey was based on covering as many habitat types as possible over as
wide a range of the reserve as possible. Plots were not used since the emphasis was on
the species diversity and inventory rather than vegetation communities, although other
surveys have used a plot-based approach in parts of the reserve previously.
In keeping with the overall project plan, there was a particular focus on species that
for any reason were suspected of not having been collected on the reserve, that were
in flower at the time since the survey was carried out at a season when most species
are not in flower, and any species seen in fruit where the collection of fruits was
considered likely to be a useful addition to Herbarium scientific collections. In
addition, requests made by colleagues were fulfilled as far as possible, relating to rare
species, putatively new species or variation that needed to be checked. An especial
search was made for plants in my particular taxonomic specialty groups, Wurmbea
5
and other petaloid monocots, and grasses. The seasonal conditions meant that weeds,
which are mostly annuals here, were scarcely visible.
Of particular interest for the overall project were species that might be new records
for the reserve, and species that might be new to science.
Methods
In preparation for the survey I prepared species lists for the Reserve from the Western
Australian Herbarium specimen database WAHERB as a guide to species known to
be present and to aid recognition of new records. There were two lists, the first of
which will be referred to as the wider WAHERB list, covered the Reserve plus an
arbitrary buffer chosen so as to limit the inclusion of habitats that are not
characteristic of the Reserve such as the large salt lakes and the Mt Gibson range. It
comprised about 570 vascular plant taxa and 60 non-vascular plants and fungi. The
buffer was included so as to improve the prospect of obtaining a species list that was
reasonably indicative of the flora of the Reserve. The second list, the Reserve list,
used coordinates closely approximating the Reserve boundaries (i.e. excluding the
buffer), and comprised about 350 vascular plant taxa. This list indicates what species
have actually been collected from the Reserve, and as expected it was significantly
less complete than the wider list, given that the Reserve has not been thoroughly
surveyed for flora. There are other less complete lists in existence, one important one
having been supplied by ABRS from Federal Government databases, and that one has
been reconciled with the Reserve list here.
Most regions of the Reserve were visited, including as many as possible of the known
vegetation types and soil and geological substrates. The vegetation is varied and
complex in distribution. Very few species were in flower, but selected collections
were made when flowers were encountered, when fruiting collections seemed likely
to be useful, when the identity of plants needed to be checked for this or other science
projects, or when new records were suspected.
The work was assisted by Earthwatch volunteers and staff and I was also
accompanied most of the time by Dr Matt Appleby, Bush Heritage plant ecologist,
who was seeing the Reserve for the first time and who discussed species, plant
communities and ecological and management issues. Dr Peter Lang from the TERN
team also joined the team when possible, which allowed us to share our knowledge of
the flora from our respective state perspectives.
Identifying the collections and vouchering
Plant identification was based on my existing knowledge supplemented by advice
from other botanists, specialists in the taxonomy of particular groups (see
acknowledgements), available keys in floras and revisions, online resources especially
the Western Australian Herbarium’s FloraBase Web resource and the AVH
(Australia’s Virtual Herbarium), and WA Herbarium collections. The sterile state of
many collections has made the process more difficult than usual.
6
Most collections were retained for lodgement in the Western Australian Herbarium as
vouchers verifying the records, but very poor specimens were not kept. The vouchers
are readily retrieved from the WAHERB database by querying for “CDR” in the
voucher field. The records are accessible to AVH queries and contribute to the AVH
maps.

Results
The species list
A full list of the vascular plants of the Charles Darwin Reserve (CDR) based on
known specimen records is presented in Appendix 1. The list contains 372 taxa,
including species, subspecies, and varieties, with care taken to avoid double counting
of taxa at species and infraspecies level. For this report the list is simply presented
alphabetically by genus.
The flora list was rather strictly limited to the area within the boundaries of the
Reserve in keeping with the objectives. One consequence is that an idea of the
collecting intensity can be gained. A comparison of the 372 taxa of this list with the
c. 570 taxa of the wider Waherb list prepared at the outset suggests that many species
that could be expected to occur in the vegetation types on the CDR have not yet been
collected there. There may also be some effect of the buffer area possibly including
habitats not present on the Reserve, but the buffers were selected to reduce this.
Figure 1 shows the distribution of collections prior to the survey.
Because of the strict limitation of the list to the CDR the new taxon records reported
here include some that could be regarded as merely minor new occurrences of taxa
that are widespread and common in the general region. However it is important that
the biodiversity actually present on the reserve be documented for reserve
management reasons, for demonstrating conservation of as many species and plant
communities as possible, and for adding to general floristic knowledge, so all records
are reported.

Taxa newly recorded for Charles Darwin Reserve
Appendix 1 includes an indication of taxa thought to be newly recorded for the
Reserve as a result of the collections made during this May 2009 survey by the plant
research team led by me, and by other scientists whose collections I undertook to
identify. The latter are not individually indicated, but the information is on record.
The new records are for convenience presented separately in Table 1.

Species excluded from the Reserve list
There are a few species that have appeared in database extracts or other lists which the
checking carried out for this project suggests do not occur in the CDR, as listed in
Table 2. The reason for the erroneous records is probably usually incorrect
identification of specimens or inaccurate geographic coordinates on the specimen or
in the database (e.g. Melaleuca filifolia), and both of these types of errors are
indicated by records that seem far out of range. Genuine outliers can occur but in
these cases it is considered unlikely. Rulingia kempeana is not listed in the table even
though there are no WA records from the region, because the available records of the
species are widely scattered and it could occur there. The Jacksonia case probably
originated by a confusion of names between the western Australian J. rhadinoclada
and the eastern Australian J. rhadinoclona via synonymy with J. stackhousei or
(correctly) stackhousii.

Un-named taxa
Taxa occurring on the Reserve or within the adjacent buffer region which are putative
un-named taxa are listed in Table 3. In general these require research to determine
their taxonomic status. Often such taxa are inadequately collected, in the sense of
insufficient knowledge of their geographic range and how they approach their closest
relatives, insufficient material to determine their variation, or the available material
lacking relevant stages such as flowers. The prospect of the formal description and
naming of these taxa being able to be accelerated varies. It is likely that not all of
these putative taxa will ultimately be described as new, because they may turn out to
have an existing name, or because they prove not to be different or different enough to
warrant recognition and naming.
There are also 20 specimens in PERTH not named to species, which may yield further
un-named taxa when checked.
None of the putatively un-named taxa are thought to be endemic to the Reserve.

New species to be described
Three of the un-named taxa belong to one of my specialist research groups, the genus
Wurmbea (Colchicaceae), often known by the common name Nancy. Two of these
occur on the Reserve and the third occurs on the neighbouring pastoral property and is
very likely to grow around granite on the Reserve as well but has not been searched
for as yet. All of these species have been recognised as new in the past two years, and
two of them were seen for the first time in 2008, on or adjacent to the CDR. This
association with the Reserve makes it appropriate for me and my colleagues to
undertake the formal description of them in association with this survey project, even
though they were not collected during the survey itself because the survey was too
early in the year. However an already named congener, W. densiflora, with which W.
sp. Paynes Find has long been confused, was collected during the survey. At the time
I considered it to be a new record but subsequently noted it in the ABRS list,
apparently based on a herbarium record not seen by me. These Wurmbea species
represent a good example of taxa which are being discovered through fieldwork
carried out at appropriate times and in good seasons, and since many of the new
discoveries are in pastoral areas, they will be conserved on reserves such as the CDR.
These new species are currently in preparation for publication (Macfarlane, Brown &
French, in prep.).

Wurmbea sp. Paynes Find
Formal phrase name: Wurmbea sp. Paynes Find (C.J. French 1237)
This recently recognised species has been long confused with W. densiflora. It is quite
widespread, and is known from Charles Darwin Reserve (e.g. the collection M.G.
Corrick 11608, PERTH). It is a tall plant with 2-8 pink flowers in a relatively loose
inflorescence, the petals spreading widely so that the flower is more or less flat, the
nectaries are concealed, and the anthers are yellow. It flowers in Spring, August to
September.

14
Wurmbea sp. White Wells
Formal phrase name: Wurmbea sp. White Wells (T.D. Macfarlane et al. TDM 4345)
This recently discovered species was first recognised as a distinct species at the
Charles Darwin Reserve, and has subsequently been found elsewhere, and may also
have been collected in earlier years. It is closely related to W. inframediana, which
grows further north. It is a small plant about 10 cm tall, with 1-5 pink or almost white
flowers in a relatively compact inflorescence, the petals bearing nectaries that are
straight, and the anthers are dark red. It flowers in Winter, June to July.

Wurmbea sp. Wanarra
Formal phrase name: Wurmbea sp. Wanarra (T.D. Macfarlane et al. TDM 4348)
Discovered for the first time in 2008 and still only known from two locations close
together just east of Charles Darwin reserve, this species is expected to also occur on
the Reserve around granitic outcrops. The plants are small, 2-5 cm tall, with usually
separate male and female plants. The flowers are white to pink-tinged, the petals each
bearing two small marginal nectaries the same colour as the rest of the petal. It
flowers in Winter, June to July.
