Flowering Period:  Unknown in Western Australia, November-April elsewhere.

Distribution and Habitat in the Moora District

This species is distributed throughout eastern Australia mainly in the south-east.  There are a few records

from Western Australia, the first made by James Drummond in 1840 without locality information other

than "Swan River".  The species is saline tolerant and seems to grow readily from seed, so it is thought that

it might have been transported around the coast from further east.  A collection from near Lake King was

found to have been made in Victoria.  There is one collection from the Moora District from near Eneabba.

There was one small plant present which was grown on before identification, with the possibility of

contamination. 

This species grows in or around standing freshwater, in water forming dense masses with intertwining

stems and long branches floating on the surface, or forming dense mats several centimetres high on moist

soils beside fresh water.  The site at Eneabba was not typical for the habitat of the species.

It is possible that this species has always been rare in Western Australia and the disjunct distribution may

represent repeated introductions which have not spread.

It has been concluded recently (F. Dawson, personal communication) that 



C. helmsii is probably not native

to Western Australia.

Daviesia debilior Crisp subsp. debilior

FABACEAE


Daviesia debilior is a straggling shrub to 0.6 m tall and 1.6 m broad with angular, ribbed branchlets and

ascending phyllodes, which are decurrent, angular, ribbed and linear, to 120 mm long, and 2 mm wide.

These are abruptly reduced to small scale leaves on the upper branches.  The flowers are in short, cluster-

like racemes with 2-4 flowers and partly enclosed at the base by overlapping, cupped bracts to 3 mm long,

which conceal the stalk of the inflorescence.  The standard petal is yellow with a dark red centre, to 5.5 x

6.5 mm, the wings and keel are dark red.  The fruit is a compressed pod, to 17 mm x 10 mm.



D. debilior subsp. debilior differs from D. debilior subsp. sinuans in having phyllodes on the lower parts of

the branches.  In subsp. 



sinuans they are all reduced to scale leaves. 

This species is related to



 D. hakeoides which has pungent phyllodes and beaked pods and the phyllodes are

reduced gradually up the stems to scale leaves.  It is also related to 



D. juncea which has larger flowers, a

differently shaped calyx and terete, striate branchlets.



Flowering Period:  May-July

Distribution and Habitat in the Moora District

Has been recorded from Eneabba to the Lesueur area in the Moora District and from Wannamal and

Darlington in the Swan Region.

Grows in shallow sand over lateritic gravel or clay amongst low open heath.

This taxon was not included in the Priority Flora List until late during this survey so was not searched for.

Daviesia dielsii E.Pritz.

FABACEAE


A divaricate shrub to 90 cm by 180 cm in diameter.  The branchlets are somewhat spinescent and they and

usually the phyllodes are tomentose with short grey, recurved hairs.  Plants in more southerly populations

are less hairy.  The phyllodes are flattened and obliquely obovate with a pungent point.  They are small, 2-4

mm x 1-3 mm. and have one or two prominent nerves.  There are no stipules.

The flowers are small, borne singly in the axils of the upper leaves.  The calyx has lobes much shorter than

the tube.  The perianth is 5-6 mm long, orange and red in colour.  The outer part of the standard is orange

or orange-red, the inner part and the wings and keel are dark red.  The fruit is a triangular pod with convex

valves ca. 1 cm long.

There has been confusion of this species in the past with 

Daviesia tomentella ms which was used in

reference to the hairy as opposed to the glabrous forms of 



D. dielsii.

Flowering Period:  July-August

Fruiting Period:  October

Distribution and Habitat in the Moora District

Known populations are located north of Moora and east of Watheroo.  The species has been collected in the

past from further south in the Koojan area and further north near Marchagee, but extensive survey in

southern part of the range has failed to refind any of those populations.

Grows on flat or upland areas on brown loam with chert, yellow-brown sand and gravel, clayey sand, or

grey sandy loam over gravel.  It occurs in tall heath over low scrub or in low heath with open shrub mallee.

Associated species include 

Actinostrobus sp., Allocasuarina campestris and Eucalyptus rhodantha.

Dryandra platycarpa A.S.George

PROTEACEAE

[

Dryandra sp. Watheroo (R.D.Royce 9625), Dryandra sp. 32]

An erect, shrub to 1.5 m, with columnar branches and without a lignotuber.  The leaves are broadly linear,

4-12 cm long, 6-17 mm wide, with revolute margins and are tomentose on the lower surface.  They have

10-25 pungent lobes on each side, to 8 mm long.  The inflorescence is on a short branchlet or is sessile,

with many linear, silky white involucral bracts to 12 mm long.  The flowers are golden yellow, the perianth

cream with a golden limb, the style cream and the pollen presenter is 1 mm long. green or cream.  The

follicles are transversely ovate.

This species can be recognised by its pinnately divided leaves, short involucral bracts, small cream and

brown flowers and broad follicles.  In the southern part of the range the leaf lobes may be broader and there

is variation in flower size.



Flowering Period:  July-October

Distribution and Habitat in the Moora District

Occurs from east of Eneabba south to Mogumber.  This species is well represented on conservation

reserves.

Grows on flat to undulating sites, mid slopes or hilltops, sometimes in swampy areas.  Occurs in heath or

tall shrubland in brown, grey to white sandy soil, sometimes with lateritic gravel.  Associated species

include species of 



Adenanthos, Xylomelum, Hakea, Banksia and Eucalyptus todtiana.

Epitriche demissus (A.Gray) P.S.Short

ASTERACEAE



Epitriche demissus is a low annual herb 2-5 cm high with stems which are simple or branching at the upper

nodes.  The leaves are opposite, sessile and lanceolate, with few hairs, 0.5-1 cm long.  The flowers are in

compound heads, with an involucre of bracts, the outer leaf-like, the inner ones densely hairy.  There are

10-20 flowers per head, each with a tubular five lobed corolla to 1.9 mm long.  The fruit is an achene,

which has a tuft of long hairs at the apex giving the clusters of flower heads a woolly appearance.

The monotypic genus



 Epitriche is allied to Angianthus and this species was included in that genus until the

account of 



Epitriche was published in 1983.

Flowering Period:  July-September

Distribution and Habitat in the Moora District

E. demissus is known from two populations ca. 6 km apart, in the Three Springs area.  It has also been

collected from ca. 40 km north-east of this in the Geraldton District.

Grows on the margins of saltlakes in sand or clayey sand with other low herbs, and just below open

woodland of 



Acacia acuminata with scrub beneath or with Halosarcia species only.

Eucalyptus abdita Brooker & Hopper

MYRTACEAE

This species was first collected in 1970 but not recognised until 1988 and described in 1991.

Eucalyptus abdita is a mallee to 3 m tall with smooth grey stems.  The leaves are at first blue-green,

maturing to green and slightly glossy.  They are lanceolate in shape, up to 9 cm long and 2 cm broad.  The

inflorescence has up to 13 flowers, each with a short stalk and the inflorescence has a peduncle up to 1 cm

long.  The buds are spindle-shaped, 1.4 cm x 0.3 cm, the operculum equal in diameter to the hypanthium

and with an acute tip, which is sometimes slightly recurved.  The fruits are up to 0.6 cm long x 0.4 cm.

This species differs from 



E. pluricaulis in its shorter, less tapering buds, and in the green, slightly glossy

mature leaves, which contrast with the dull blue-green new growth.  The specific name comes from the

Latin for hidden or concealed, as this species was at first overlooked and thought to be 

E. pluricaulis.

Flowering Period:  July-September

Distribution and Habitat in the Moora District

E. abdita has been recorded from five disjunct populations over a geographic range of over 100 km from

the Dandaragan area to south-west of Mingenew.

It grows on lateritic soils, sometimes near breakaways and has been recorded on yellow-brown sandy clay

with gravel in open low mallee woodland over dwarf scrub with



 E. leptophylla,  Daviesia  sp. and

Calothamnus sp.  Associated eucalypts include E. arachnaea subsp. arachnaea and E. gittinsii.

Eucalyptus angularis Brooker & Hopper

MYRTACEAE



Eucalyptus angularis is a mallee to 3 m tall with rough grey bark at the base of the stems or for the first

metre from the base.  The branchlets are slender and angular.  The leaves are small, elliptic to falcate or

lanceolate in shape, 6-10 cm x 1.5 cm with minutely recurved edges.  They are glossy and green and

densely veined.  The inflorescences are up to 11-flowered, on slender angular or flattened peduncles 1-2 cm

long.  The buds have stalks and are spindle-shaped but mature buds and fruits are not known.

It is thought possible that this taxon is a hybrid of 



E. marginata and possibly E. exilis or E. pendens

Flowering Period:  Unknown

Distribution and Habitat in the Moora District

Two populations are known, one in the Lesueur area and another ca. 10 km to the south-east.  Both

populations occur on lateritic breakaways as a single clump of mallees emergent over low heath.

Eucalyptus diminuta Brooker & Hopper ms

MYRTACEAE

A mallee to 5 m tall, with the stems grey in colour over smooth copper-coloured bark.  The leaves are

glossy and dark green in colour.  The buds are pendant on slender rounded peduncles.  The operculum is

elongated and cylindrical with slight or no ribbing, and the fruits are cup-shaped to cylindrical.

This species is similar to 



Eucalyptus stowardii but differs in its smaller, less glossy leaves, buds and fruits

and in the absence of, or reduced ribbing on buds and fruits.  The coppery bark also distinguishes the

species. 

Flowering Period:  May, July and September-January

Distribution and Habitat in the Moora District

Known from two areas, north-east of Geraldton in low stony hills, and in the Moora District from west of

Three Springs over a range of 30 km and with earlier records from east of Eneabba and Jurien Bay.

Grows along drainage lines or in swampy areas on hillsides or flats, sometimes below breakaways, on

quartz, sandstone or sand over laterite in grey, white or yellow-brown sand, grey sandy clay or white kaolin

soil.  The plants grow emergent over low scrub, in shrublands or open low woodland.  Associated plants

include species of 

MelaleucaDryandraEucalyptus and Kunzea
