Dryandra kippistiana A.S.George var . paenepeccata A.S.George
PROTEACEAE
[
Dryandra sp. 46 (A.S.George 16866) [aff. sclerophylla]]
A lignotuberous, multistemmed, erect shrub to 1.2 cm tall, with linear, pinnatifid leaves which
have 10-20 lobes. They are white-tomentose below. The flowers are pale yellow, grouped 50-80
per head. The inner involucral bracts are up to 10 mm long, shorter than the flowers. The
perianth has fine spreading hairs and is 18-20 mm long. The pistil is 24-25 mm long. The
follicles remain closed until burnt.
This variety differs from var.
kippistiana in the later flowering time (August to October in var.
kippistiana) and in the leaves, which are straighter, more erect and coarsely lobed than those of
var.
kippistiana. Both varieties are vegetatively similar to Dryandra sclerophylla, but are
distinguished by the pistil, which is more slender and is looped before anthesis and has a thicker
pollen presenter. There has been considerable confusion in the past between these taxa.
Flowering Period: October-November
Distribution and Habitat in the Moora District
Occurs at scattered localities within the range of the species, from Eneabba and Mt Lesueur to the
southern boundary of the District.
Also occurs further south in the Gingin and Armadale areas in the Swan Region.
Grows on lateritic uplands, in low open heath in grey brown sandy gravel or grey sand over
laterite. Associated species include
Calothamnus sanguineus, Hibbertia hypericoides and
Lambertia multiflora.

Susceptibility to Phytophthora Dieback

Presumed susceptible
Management Requirements
- Ensure that dieback hygiene procedures are carried out at all populations.
Research Requirements
- Further survey is required to refind and survey all past recorded populations and to establish
the full extent of the variety throughout the range. Taxonomic confusion in the past has been
clarified by recent work by A.S. George and it should now be possible to assess accurately the
conservation status of the taxon.

Dryandra stricta A.S.George
PROTEACEAE
This species was originally included on the Priority Flora List as
Dryandra sp. 15 (E.A.Griffin
3453) [aff.
hewardiana] and was listed as Dryandra aff. patens (E.A.Griffin 1507) in Burbidge
and van Leeuwen (1990). It was referred to as
Dryandra sp. I (Voucher E.A.Griffin 2404) in
Griffin (1985). (The account on P.30 should read "related to
D. patens", not " D. armata".
A shrub to 3 m tall, without a lignotuber. It is single-stemmed at base, usually much-branched
and spreading or erect and columnar. The branches are densely leaved, leaves rigid, dark green in
colour and white-tomentose beneath. They are 5-20 cm long, 4-9 wide with 8-18 triangular teeth
on each side. The flower heads are in the upper leaf axils, surrounded by a few floral leaves. The
flowers are pale yellow or cream, 23-25 mm long, with a straight pistil to 31 mm long. The
follicles have prominent veins.
Flowering Period: August-October
Distribution and Habitat in the Moora District
Endemic to the Moora District, occurring between the Eneabba and Badgingarra areas.
A large population has also been recorded in the eastern section of Lesueur National Park
(Burbidge and van Leeuwen 1990).
Grows on lateritic rises amongst massive laterite in grey sand or clay and gravel in scrub or dense
to low open heath. Sometimes occurs in open mallee woodland with
Eucalyptus drummondii or
in sandy loam over sandstone in open heath. Also occurs in lower damp areas, near a creek and
in wandoo woodland.

Dryandra trifontinalis A.S.George
PROTEACEAE

Eucalyptus annuliformis P.M.Grayling & Brooker
MYRTACEAE
A mallee to 3 m tall, with smooth grey bark. The leaves are elliptic to broadly lanceolate,
alternate and dull green in colour. There are 7 flowers in the inflorescence. The buds have
pedicels to 1.7 cm long and each bud has two bud caps, the inner is shed early, the outer is
conical and slightly beaked. The fruits are hemispherical, 1.1 x 1.4 cm with a thick rim and broad
disc.
Eucalyptus annuliformis is possibly of hybrid origin with E. drummondii as a parent. It flowers
profusely, produces abundant fruit but no viable seed has yet been collected. The pollen fertility
is low.
It differs from
E. drummondii in the grey bark, rather than white, in the larger, non-glaucous buds
(to 2 x 1.3 cm), the beaked bud caps, and the disc of the fruit which is flat, not domed, and forms
a ring, becoming sunken.
Flowering Period: May-September
Distribution and Habitat in the Moora District
Known from one small population south-east of Dandaragan.
Grows in shallow, white sandy soil on a lateritic breakaway in open low woodland of
E.
calophylla over low heath with Hibbertia hypericoides, Dryandra sp., Hakea trifurcata, Acacia
pulchella, Melaleuca radula and Hakea sp.

Eucalyptus macrocarpa Hook. x pyriformis Turcz.
MYRTACEAE
A mallee 1.2-3 m x 5-15 m. The stems sometimes have a brown, flaking stocking and are smooth
and cream to grey above or may have patches of brown, flaking bark. The leaves are petiolate,
ovate-lanceolate in shape, and are opposite to alternate and glaucous. The buds are large, ovoid,
to 4 x 4.5 cm in diameter, the bud cap with a short beak. The flowers are red, pink or yellow.
The fruits have peduncles to 1.5 cm long and are often ridged and have a moderately protruding
disc. They are up to 5 cm in diameter.
The most northerly population, which occurs in the Geraldton District, is a hybrid between
Eucalyptus macrocarpa subsp. elachantha and E. pyriformis and is a low mallee to 1.5 m with
small, narrow leaves.
Flowering Period: April and August-December
Distribution and Habitat in the Moora District
Occurs mainly within the Moora District along the eastern side south to the Calingiri area. The
most northerly population occurs west of Mingenew in the Geraldton District and the most
southerly population occurs south-east of Bolgart in the Merredin District. There is also a record
from Cunderdin 70 km south-east of Bolgart.
Grows on yellow or grey sand or sandy loam, sometimes over gravel or associated with laterite,
in low heath, sometimes in tall scrub with
Actinostrobus sp. or in open mallee woodland. It
occurs on slopes, ridges and hilltops and often grows in association with
E. macrocarpa.

Eucalyptus subangusta (Blakely) Brooker & Hopper
MYRTACEAE
subsp
. virescens Brooker & Hopper
A mallee, 2-5 m tall with grey or pale copper, smooth bark. The pith of the branchlets is
glandular. The juvenile leaves are dull, bluish-green to green, the adult leaves are glossy,
lanceolate in shape, to 11 cm long and ca. 1 cm wide. There are groups of up to 17 white flowers
in each inflorescence and the peduncle ca. 1 cm long. The buds are spindle-shaped, 1 cm x 0.3
cm. The operculum is the same width as the hypanthium at the join on mature buds. The fruit is
cup-shaped with a short stalk 5 mm x 5 mm.
Differs from the typical subspecies in the adult foliage which is light green and slightly glossy in
the older leaves within the crown. The foliage of all the other subspecies is dull and blue-green.
Flowering Period: Unknown
Distribution and Habitat in the Moora District
Known from only four populations occurring between Manmanning in the Merredin District and
Watheroo in the Moora District and near Narambeen in the Narrogin District. Grows on a range
of soil types, from yellow sand with
Eucalyptus flocktonii and E. sheathiana to white clay with E.
yilgarnensis and E. erythronema. Also occurs on clay loam with E. salmonophloia.
All four populations are on road verges in largely cleared agricultural land.

Eucalyptus sp. Lesueur (E.A.Griffin 2481)
MYRTACEAE
A low, spreading mallee to 1.5-3 (5) m tall. The bark is tessellated and rough at the base, smooth
and creamy-white above. The leaves are short, slightly glossy and light green, with dense
venation. The buds are 7-12 cm x 0.4-0.6 cm, with a hemispherical or slightly beaked budcap.
The fruits are barrel or urn-shaped, with a narrow opening, to up to 3.8 cm x 2.6 cm.
Brooker and Kleinig (1990) included this taxon as a disjunct mallee form of
Eucalyptus
haematoxylon which occurs on the western side of the Darling Range from east of Byford south
to east of Capel.
Differs from the southern form, which is a small tree, in its mallee habit and in the glossy leaves,
which are dull in the southern form.
The taxonomic status of this taxon is at present uncertain but it is possibly an undescribed species
and it is important to maintain its conservation status.
