Homalocalyx chapmanii Craven
MYRTACEAE
Homalocalyx chapmanii is an erect shrub to 50 cm tall. The leaves are small and alternate with
very short petioles. They are narrowly oblong to obovate, to 3.5 mm long and to 1.3 mm broad.
Stipules are present. There are 3-20 inflorescences, clustered, in the lower leaf axils of new
growth, the shoot apex continuing growth. Each flower has a pair of persistent bracteoles joined
to form the cheiridium. There are bud scales present. The hypanthium is short, pubescent with
10 ribs and the apex of the ovary is concave. There are five reflexed and persistent sepals which
are rounded, with an irregularly toothed edge, to 7.2 mm long. The five petals are magenta to
light purple in colour, rounded, to 3.5 mm long. There are 40-50 stamens with the filaments the
same colour as the petals. The style is persistent. The fruit is dry and indehiscent with one seed.
Flowering Period: September-October
Distribution and Habitat in the Moora District
The species has been collected several times from the area north-east of Eneabba but was not
fully surveyed as it is a recent addition to the Priority Flora List. It also occurs in the
Northampton to Hutt River area.
Grows in open heath on yellow or light brown sand, in low open heath on shallow greyish sand
over weathered granite or on grey-brown clay over laterite in shrubland. One collection was from
a somewhat damp valley flat (E. Griffin, personal communication).

Hydrocotyle coorowensis H.Eichler ms
APIACEAE
A low herb to 5 cm tall, with cordate leaves divided to the middle into three lobes, the upper one
with three teeth, the outer ones with four teeth. The flowers are in umbels. Each flower has five
minute calyx lobes, five small petals and five stamens opposite the calyx lobes. The fruit is
composed of two fruitlets. It is pale brown, with long tubercles and only one fruitlet is winged,
the wing much broader than the body of the fruit and with long marginal hairs.
Flowering Period: August
Fruiting Period: September
Distribution and Habitat in the Moora District
Occurs between Three Springs and Watheroo and is endemic to the Moora District. Few
collections have been made and it is possible that the species could occur further east outside the
District in similar habitats. It has also been found on several lake beds in the north-east corner of
Watheroo National Park where in places it was very common (E. Griffin, personal
communication).
Grows on the upper margins of salt lakes associated with
Halosarcia species and on low winter-
wet flats, on white sand and grey clay in herbfields with associated species including
Angianthus
tomentosus and Puccinellia stricta.

MYRTACEAE
[
Hypocalymma sp. Lesueur (E.A.Griffin 1972) [aff. ericifolium]]
A low shrub to 25 cm tall and 50 cm in diameter. The leaves are opposite, linear, ca. 5 mm long
and 0.5 mm wide. The flowers are cream to pale yellow in colour, sessile in pairs at the base of
the leaves.
Flowering Period: July-October
Distribution and Habitat in the Moora District
Occurs over a range of ca. 6 km to the north and north-east of Mt Lesueur. There is also a report

recorded from eight locations, in some of which it was common (E. Griffin, personal
communication).

woodland over low shrubland. It has also been recorded from brown sandy loam or grey-brown
sand over sandstone on breakaway slopes in open mallee and
Banksia tricuspis woodland with
associated species in low heath, including
Hakea species, Dryandra armata, Acacia sp. It often
occurs on the slopes above creeklines.

Jacksonia sp. Badgingarra (H.Demarz D6601) [sp. 14]
FABACEAE
A low woody shrub, to 0.3 m tall, sometimes prostrate. It is leafless and the upper stems are
usually flexuose, with sharp angles. The flowers are bright red in colour.
This taxon may be synonymous with
Jacksonia rubra ms, a Priority 2 species which occurs near
Tammin.
Flowering Period: August-October
Distribution and Habitat in the Moora District
Collections in the Western Australian Herbarium suggest that the taxon occurs over a range of ca.
10 km to the north of Badgingarra and possible further south-east. However, the locality
information on all four collections is not very clear.
Has been recorded growing in yellow sand and in wet sand, in dense scrub 20 cm high, and in
heath.

Lasiopetalum ogilvieanum F.Muell .
STERCULIACEAE
This species was described by Mueller from collections made between the Greenough and Irwin
Rivers. It is an erect shrub 0.5 m to 2.6 m tall with alternate leaves which are entire, narrow,
almost glabrous on the upper surface, with a dense covering of whitish to rusty stellate hairs on
the lower surface. They are to 6 cm long and 1 cm broad. The inflorescence is a loosely-
branched raceme, the pedicels 4 mm long. There are narrow, thread-like bracteoles at the base of
each flower stalk. The calyx is thin in texture and hairless on the inside, to 1 cm in diameter,
divided more than half way into five acute lobes. It is pink in colour, densely hairy on the
outside, appearing white owing to the white stellate hairs, and the edges of the lobes are rusty in
colour, particularly in bud. The petals are small, hairless and purple in colour. The stamens are
purple, the filaments much shorter than the anthers. The ovary is hairy, the style hairless.
Flowering Period: July-September
Distribution and Habitat in the Moora District
Has been collected from an area west of Three Springs in the north of the Moora District.
Grows in deep grey, white or yellow sand with
Eucalyptus todtiana in low closed heath or in
open heath and scrub.
The species requires further survey particularly in conservation reserves and uncleared remnant
vegetation in the Carnamah to Dongara area. It is known only from five collections made this
century, apart from the Type collection, and there is little habitat information. The location
south-west of Three Springs was searched during this survey but the species was not refound.
Natural vegetation at this location is now restricted to road reserves.

Lasiopetalum sp. Hill River (T.N.Stoate s.n.)
STERCULIACEAE
A spreading shrub 30 to 60 cm tall with leaves which are orbicular to ovate in shape, deeply
cordate, with scattered stiff stellate hairs on both surfaces, otherwise glabrous. They are 1-3 cm
broad. The flowers are in loose, branched inflorescences to ca. 4 cm long. The bracteoles are
broad, ovate, purple-pink in colour and there is one on each pedicel, distant from the calyx. The
calyx is ca. 6 mm long, deeply divided more than half way into five narrow acute lobes. It is
greyish-pink in colour, darkening to purple at the base of the inner surface. Both surfaces have a
covering of short pale hairs, restricted to the lobes on the inner surface. There is a less dense
layer of longer hairs on the outside. The stamens are broad, purple in colour. The style has
reflexed, stellate hairs.
Appears to be closely related to
Lasiopetalum membranaceum which has ovate leaves and occurs
in the Dwellingup to Capel area.
Flowering Period: August-October
Distribution and Habitat in the Moora District
Populations are known from Badgingarra to Dandaragan. There are two earlier collections, one
from “Hill River” and the other from Three Springs.
Grows in low heath, and mallee heath on lateritic uplands, slopes and breakaways in brown loam
and lateritic gravel or grey sand and gravel.

Lechenaultia juncea E.Pritz.
GOODENIACEAE
Reed-like Lechenaultia
This species was described in 1905 from specimens collected by Pritzel in 1901 from between the
Moore and Murchison Rivers.
It is an erect plant to 50 cm tall, with reed-like hairless stems, almost leafless and with few
branches. They are smooth on the upper parts, with rough pale bark only at the base of the plant.
The leaves are few, scattered on the lower flowering stems and crowded on the short leafy stems.
They are narrow, hairless and fleshy, 8.5-16 mm long. The flowers are in loose, few-flowered
inflorescences. The sepals are 5-6 mm long and are all the same length. The flowers are pale
blue, 14-18 mm long, with the upper two corolla lobes free and spreading, with very narrow
wings if present. The corolla tube is hairy on the inside and is open on one side to the base. The
style is 7.5-8.5 mm long, glandular hairy, and the indusium is hairy on the back.
Flowering Period: Late October-December
Distribution and Habitat in the Moora District
Occurs from south-west of Carnamah south to the Watheroo area. It is not conspicuous and
flowers in summer so may be under-recorded. It has been recorded from north-east of the
Watheroo National Park (Carger Road and from the Marchagee Track (E. Griffin, personal
communication
.).
Grows in yellow or white sand or sandy gravel in heath and low scrub. Associated species
include
Actinostrobus arenarius and Banksia prionotes.
