# now extant Declared Rare Flora (updated at December 1999) 132 References Blackall and Grieve (1991), Fitzgerald (1904), Mollemans et al. (1993). 133 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). Conservation Status Current: Declared Rare Flora, Presumed Extinct #

Bentham (1863), Hewson (1982), Hooker (1844), Leigh et al. (1984), Mueller (1861), Shaw (1970). 135 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
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.

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
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

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.

Maslin (personal communication). 5 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
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.
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. Conservation Status Current: Priority 1 #

Research Requirements - Further survey is required. References B. Maslin (personal communication), Meisner (1855). 7 Acacia congesta Benth. subsp. cliftoniana (W.Fitzg.) Maslin ms MIMOSACEAE This taxon was originally described in 1904 by W.V. Fitzgerald as
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
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.
