Menkea draboides (Hook.f.) Hook.f. ex Benth.
BRASSICAEAE
This species was collected by James Drummond in 1843 and since then has been collected only three times.
It was originally described and illustrated by Hooker as
Stenopetalum draboides.
Menkea draboides is a prostrate, spreading herb, with hairless stems to 60 cm long. The basal leaves are
obovate, entire or with a few lobes or teeth. They are ca. 3 cm long and ca. 10 mm wide, the blade
narrowing to a slender stalk almost as long as the blade. The stem leaves become smaller, higher up the
stems. The flowers are white, borne in dense, few-flowered inflorescences. There are four sepals and
petals. The latter are ca. 3 mm long, with a broad blade narrowing to a linear claw. There are six stamens,
a papillose ovary and short style. The seed pod is flattened and dry, splitting down two sides, leaving a
central partition. It is often twisted and the valves are papillose. The seeds are dark red-brown in colour.
Differs from other species of
Menkea in the twisted, papillose seed pod.
Flowering Period: August-September
Distribution and Habitat in the Moora District
Apart from two collections made in the Moora District, the species has also been found in 1889 at Yilgarn
near Southern Cross in the Merredin District. The collection made by Drummond is without location
information. Of the collections made in the Moora District, there is some doubt as to whether the
collection from the rabbit proof fence (ca. 50 km east of Watheroo) was made from that area, which is on
the border with the Merredin District or from Wooroloo, which is north-east of Perth in the Swan Region.
Recent taxonomic study has brought to light five collections of this species, from north of Meekatharra in
1986, and in 1980 from north of Paynes Find, Woodline and north-east of Norseman.
It grows in clay or red loam over granite, or in granitic loamy sand, in wet places including drainage lines
and at Woodline with samphire on the margin of a salt lake (B. Lepschi,
personal communication).

Platysace dissecta (Benth.) C.Norman
APIACEAE
Dissected Platysace
This species is known from one collection made by James Drummond, between the Moore and Murchison
Rivers last century. It was described by Bentham in 1866 as
Siebera dissecta, and the new combination
was made by Norman in 1939.
Platysace dissecta is an upright plant to 0.3 m tall with leafy stems and sturdy, widely spreading branches.
The leaves are divided two or three times into narrow, tapering lobes. The flowers are arranged in compact
umbels on stout stalks, with many flowers in each umbel. The fruit are as long as broad, smooth, slightly
swollen in the centre of the carpels, flat on the dorsal edge, with fine intermediate ribs. It is thought that
P.
dissecta is a leafy variant of P. juncea (B. Rye, personal communication).
Flowering Period: Unknown
Distribution and Habitat in the Moora District
The species has been recorded from between the Moore and Murchison Rivers and could therefore occur in
the Moora and/or Geraldton Districts. There are no recorded details of habitat.

A. Priority One Taxa
Acacia carens Maslin
MIMOSACEAE
First collected in 1973 by Charles Chapman,
Acacia carens is an open broom-like shrub up to 0.6
m tall. The terete green branches have yellow ribs. The phyllodes are continuous with the
branches and are reduced to rudimentary stipule-like appendages 0.5 mm long, or to minute
phyllodes 1-2 mm long. The peduncles are densely hairy, 2-5 mm long. The flower heads are
globular, 8 mm in diameter. The legumes are linear and curved, to 10 cm long, ca. 4 mm wide.
This species, when originally collected, was identified as
A. volubilis which has tortuous stems
and which also differs in phyllode and calyx characters. It has also been confused with
A.
cumminghamia which differs in its longer peduncles and in other characters of the flowers and
legumes. The reduced phyllodes of this species are alluded to in the specific name, which is
derived from the Latin
carens, meaning lacking.
Flowering Period: April-May
Distribution and Habitat in the Moora District
A. carens is endemic to the Moora District and has been collected in the past over a geographic
range of about 15 km in the Gairdner Range, but is known at present from three populations with
a range of less than 10 km. Two of these populations are on road verges, the other population of
only four plants, is located within a national park. It has been reported from over 30 locations in
the Lesueur National Park (E. Griffin, personal communication).
This species grows on uplands of lateritic gravel or sandy gravel in low heath, or in open low
woodland and low scrub. Associated species include
Eucalyptus drummondii, E. calophylla and
Daviesia species.

Acacia chapmanii R.S.Cowan & Maslin
MIMOSACEAE
subsp.
australis R.S.Cowan & Maslin ms
This taxon has been collected only four times, originally in 1971, by S. Paust.
It is a low dense shrub to 50 cm tall. The phyllodes are terete, pungent and 8-nerved, 2-3 mm or
to 5 mm long, ascending and gently recurved. The peduncles are 12-19 mm long, and the yellow,
globular flower heads are 24-27 flowered and are 5 mm in diameter. The legumes and seeds are
not known.
Flowering Period: August-September
Distribution and Habitat in the Moora District
Occurs in the Bolgart area. A recently surveyed population of 400 plants occurs on a nature
reserve just outside the southern boundary of the Moora District, but the taxon was recorded in
1971 and 1972 from between Bolgart and Calingiri and from north of Wyening in the south-
eastern corner of the District. The geographic range is ca. 17 km.
Grows in sand, sandy gravel or sandy clay with laterite in open low woodland over low heath,
sometimes in winter wet areas.

Acacia cochlocarpa Meisn. subsp . cochlocarpa ms
MIMOSACEAE
This subspecies is restricted to the Watheroo area and there is also an early collection from near
Moora. It was first collected by James Drummond from "Swan River" and "between Moore and
Murchison Rivers" and was described by Meissner in 1855. Diels made a collection in 1901
"westward from Moora" and subsequent collections have been made from the Watheroo area.
Acacia cochlocarpa subsp. cochlocarpa ms is a sprawling, glabrous shrub to 0.7 m tall with
slightly flexuose branchlets. The phyllodes are linear to narrowly elliptic, 3-7.5 cm long, 3-6 mm
wide, incurved and erect, with 7 nerves per face. The flower heads are golden, sessile and
cylindrical, 7-10 mm long. The legumes are tightly coiled, 3-4 mm wide.
This taxon is similar to
A. alocophylla, which has 8-nerved phyllodes, and to A. tetraneura which
has 4-nerved phyllodes and bracteoles exserted on the buds.
A. cochlocarpa subsp. velutinosa ms
occurs near Manmanning and differs in its shorter phyllodes, velutinous branchlets, phyllodes and
legumes, and in its smaller, oblongoid flower heads.
Flowering Period: June-July
Distribution and Habitat in the Moora District
Has been recorded in the past over a range of ca. 20 km north of Watheroo but most of these
roadside populations appear to have been lost. Only two populations have been surveyed recently
in this area and these grow within a kilometre of each other. The population known from an early
collection made from west of Moora has not been refound. This is some 45 km south of the main
range of the species.
Grows mainly in disturbed roadside situations on sand, or clayey sand with laterite in open
shrubland. Associated species include
Allocasuarina campestris.

Acacia congesta Benth. subsp . cliftoniana (W.Fitzg.) Maslin ms
MIMOSACEAE
This taxon was originally described in 1904 by W.V. Fitzgerald as
Acacia cliftoniana but is now
included by B. Maslin (personal communication) as a subspecies of
A. congesta. It was first
collected in 1903 by Fitzgerald from Arrino.
A. congesta subsp. cliftoniana ms is a low shrub 0.5-1 m tall, with hirsute branchlets and
phyllodes. The phyllodes are 5-10 mm long, 1.2-2.5 mm wide. The flower heads are globular to
shortly oblongoid, 30-40 flowered. The legumes are constricted between the seeds and are 4-5
mm wide. This subspecies is somewhat similar to
A. idiomorpha which has more undulate
phyllodes, with a convex abaxial margin, and there are differences in the calyx, petals and
legumes. It is also similar to
A. paradoxa which has acute or obtuse phyllodes and more
prominent stipules.
A. congesta subsp. congesta has longer glabrous phyllodes, and flower heads
which may have more flowers and which may be arranged in racemes.
A. congesta subsp.
wonganensis occurs only in the Wongan Hills area. It has glabrous phyllodes and flower heads
arranged in racemes.
Flowering Period: August-September
Distribution and Habitat in the Moora District
Has been collected in the past from Yandanooka, which is just north of the boundary of the
Moora District to near Three Springs, a geographic range of ca. 25 km. It is at present known
from three road verge populations south of Arrino with a range of 2.3 km.
Grows on lateritic gravel and brown loam in open scrub beneath open low woodland
communities. Associated species include
Eucalyptus wandoo and A. flabellifolia.

Acacia flabellifolia W.Fitzg.
MIMOSACEAE
This species was first collected by W.V. Fitzgerald in 1903 from Arrino and was described by
him in 1904.
A spreading shrub to 1 m tall,
Acacia flabellifolia has rigid, undulate phyllodes ending in a long,
pungent point. The upper margin is rounded and the principal nerve runs close to the lower
margin. The flower heads are globular and solitary and the legumes are tightly coiled.
A. dilatata is a species with similar phyllodes, and occurs within the range of A. flabellifolia, but
is not closely related.
Flowering Period: August
Distribution and Habitat in the Moora District
Has been recorded as occurring between Yandanooka and Watheroo, a geographic range of just
over 100 km and it is at present known from four populations occurring between Arrino and
Watheroo.
It grows in rocky or lateritic loam on low hills in open eucalypt woodland. Associated species
include
Eucalyptus wandoo and E. loxophleba.

Acacia lanceolata Maslin ms
MIMOSACEAE
This species was first collected by Blackall in 1940 from Three Springs.
Acacia lanceolata ms is a much-branched shrub to 1 m tall. The branchlets are spinose, with
lanceolate phyllodes, 7-13 mm long and 1.5-4 mm wide, each with a pungent point. The flower
heads are globular to shortly oblongoid and the legumes are tightly coiled.
Flowering Period: August-September
Distribution and Habitat in the Moora District
Has been collected from Arrino northwards into the Geraldton District east of Mingenew. Two
populations have been located recently but as the species was not included on the Priority Flora
List until late during this survey, no others have been found.
Grows on low hills, usually on laterite, in eucalypt woodland or tall shrubland of
Allocasuarina
species.
