Grevillea superba P.Olde & N.Marriott
PROTEACEAE
[ex. 
Grevillea sp. Scaddan (P.Olde 91/332)]
A robust shrub, 2-3 m tall, without a lignotuber and with emergent floral branches up to 1 m above the shrub.
Branchlets are hairy.  Leaves (20-70 mm) are almost pinnate with 9-17 primary leaf lobes (5-20 x 1-2 mm) that are
linear and smooth; the lower lobes are usually again divided.  Clusters of flowers are at the ends of branches and usually
5-10 branched.  Flowers are borne on hairy stalks (7-10 mm); the calyx tube (7-10 x 2-4 mm) is whitish over olive green
ageing pink, strongly rolled backwards at the tip, densely glandular-hairy on the outside and covered with hairs over
most of the inside except for the tip; the style is cream or pink and red at the end, gently curved and dilated at the tip; the
pollen presenter is lateral and flat to convex.  Fruits are subglobular (17 x 15 mm) and rough with 2 prominent swellings
towards the end and a persistent, fragile style.
Grevillea superba is closely related to G. plurijuga which has trigonous leaf lobes that are undivided at the base, and its
flowers are usually within the shrub.
Flowering Period:  October - December
Distribution and Habitat
G. superba is distributed between Scaddan and Mt Ney, a range of 70 km.  It grows in white sand over pale-brown,
calcareous loam in 
Eucalyptus shrubland.

Response to Disturbance
Appears to be a short-lived perennial that regenerates from seed after fire (Olde and Marriott 1993).
Susceptibility to Phytophthora Dieback
Unknown
Summary and Recommendations
Olde and Marriott (1993) indicate that 30 specimens were examined for their species description, which suggests that
G. superba is relatively common.  They indicated, however, that many of the plants in the road reserves around Scaddan
appeared to be dying when surveyed in 1992.  Research to determine the reproductive biology of
 G. superba and
monitoring of known populations is required.

Haegiela tatei (F.Muell.) P.S.Short & Paul G.Wilson 
ASTERACEAE
An inconspicuous annual herb, 2-8 cm tall, with stems and leaves covered in cobwebby, filamentous hairs that become
flattened at the base.  Leaves are continuous with the branch, lanceolate or linear (3-7 x 0.5-1 mm), hairless or
cobwebby, the lower ones are opposite and joined together at the base.  The flower heads (2-3 mm diameter) are
virtually without stalks and solitary in the axils.  The involucral bracts (15-20) are arranged in 3 rows with all bracts
prominently incurved and having ciliate margins.  The florets just exceed the involucre; the outer florets (22-49) are
female and threadlike; the inner bisexual florets (7-11) have a cylindrical corolla (1.5 mm) that has 4 very short lobes.
Pappus are absent.
Flowering Period:  September - November
Distribution and Habitat
Haegiela tatei is widely dispersed in Western Australia, South Australia and western Victoria, south of latitude 31°S.  It
is apparently restricted to saline habitats.

Susceptibility to Phytophthora Dieback
Unknown
Summary and Recommendations
H. tatei is widespread in Western Australia, and being inconspicuous is probably poorly collected rather than rare.  It
should remain secure within two Nature Reserves and two National Parks.  Further opportunistic survey is required.

Susceptibility to Phytophthora Dieback
Unknown
Summary and Recommendations
According to Burgman (1985b), this taxon appears to be restricted to rocky outcrops in well watered micro-habitats.  It
is an inconspicuous annual and may be more widespread than collections (or lack of them) indicate.  It is not known to
occur in any conservation reserve.
A search for Burgman's specimens, which are possibly in storage at the Western Australian Herbarium, is urgently
required.  Further survey cannot be carried out until a specimen is available.

Isopogon alcicornis Diels
PROTEACEAE
Elkhorn Coneflower
A dwarf shrub, 25-40 cm tall, with thick underground stems giving a suckering habit.  The lower leaves on the stubby
stems are narrow, widening towards the tip (up to 10 cm long including a long leaf stalk) and entire; the upper, floral
leaves (up to 20 cm) are erect, flat, forked into 3 irregular lobes which look like antlers, leathery in texture and hairy on
both sides.  The yellow flower heads form egg-shaped cones (about 5 cm diameter) which are hidden in the foliage close
to the ground; the tube and 4-perianth segments of individual flowers (2 cm long) are hairy, the end of each segment has
a spoon-shaped cavity which holds an anther.  Dried cones (fruits) have scars where the scales have fallen.
Flowering Period:  October - November
Distribution and Habitat
Isopogon alcicornis is distributed over about 140 km, between Gibson and Mt Baring.  It grows in sand in open mallee
and heath communities.

Susceptibility to Phytophthora Dieback
Field observations suggest high susceptibility.
Summary and Recommendations
Surveys of Scaddan and Norwood Roads in 1992 found that where the known populations previously occurred, there
were dead plants of the Proteaceae family, suggesting 
Phytophthora dieback may be present, and no live plants were
located.
Although
 I. alcicornis occurs in two Nature Reserves and one National Park, it is never abundant and may still be
vulnerable and endangered by dieback at these localities.  At Mt Burdett, the population lies below a walk trail to the
summit and regularly receives runoff from areas traversed by humans and vehicles.  Management of the track is
required.

271
Research is needed to determine the susceptibility of 
I. alcicornis to Phytophthora spp.  Seed has been collected and
lodged in the CALM Threatened Flora Seed Centre (WA Herbarium).  Known populations need to be monitored.
Further survey is urgently required.

Lasiopetalum maxwellii F.Muell.
STERCULIACEAE
An erect, spreading shrub, 15-60 cm tall, with numerous branches.  Leaves are alternate, broadest towards the point of
attachment (ovate, 25-40 x 8-15 mm) and have margins that are slightly rolled backwards; the upper surface is green and
lacks hairs while the underside is pale green with a dense cover of matted, stellate hairs.  Flowers are borne in an
elongate cluster (raceme); sepals (4-5 mm) are cream, with matted stellate hairs forming a dense cover on the outside
and being only scattered on the inner surface with the greatest density towards the tip; petals are minute and hairless;
anthers and their filaments are about equal in length.  The ovary is densely silky-hairy; the style is without hairs.
Flowering Period:  September - January, April
Distribution and Habitat
Lasiopetalum maxwellii occurs on or near granite outcrops in coastal areas between Cape Le Grand and Cape Arid.  It
grows in sandy skeletal soil in rock crevices and hollows, often exposed to salt-laden winds.

Summary and Recommendations
L. maxwellii is abundant and secure on granite headlands in the Cape Le Grand National Park; it is also frequent in Cape
Arid National Park.  Further opportunistic survey along the coast east of Esperance is recommended.
The genus 
Lasiopetalum is currently under revision (C. Wilkins, personal communication).  Further taxonomic work
may determine the extent and status of this species.

Lepyrodia fortunata L.A.S.Johnson & B.G.Briggs ms
RESTIONACEAE
A spreading, tufted sedge, up to 1 m tall and 1 m diameter.  Culms are cylindrical (0.5-1.3 mm diam.), erect, dull green,
smooth or pitted, have 5-10 internodes apically increasing in length (to 15 cm).  Sheaths (3-20 mm) are brown and held
close to the culm except when subtending a branch; the apex is acute when young and withers with age.  The
inflorescence is panicle-like (2-10 cm), with flowers crowded on the culm or at the ends of short side branches.  Flowers
have rigid, brown tepals; outer tepals are lanceolate (3.5 mm) and keeled; inner tepals are slightly shorter and concave to
flat, broad lanceolate.  Seeds are white and crescent-shaped (1 mm).
Flowering Period:  September - November
Distribution and Habitat
Lepyrodia fortunata ms is known from two localities 40 km apart, in Cape Le Grand National Park and near Condingup.
It grows in peaty sand in swamps behind foredunes, associated with 
Agonis parviceps and sedges.

Leucopogon breviflorus F.Muell.
EPACRIDACEAE
An erect shrub, about 30 cm tall.  Leaves are held erect, concave, elliptic (10 x 2 mm), stalked, and have a rigid, sharp
point.  On the lower side of the leaf there are 3 parallel central veins and other veins branching towards the margin.  The
white flowers are erect with 2 or 3 borne together on short, finely-hairy stalks in the axils of leaves; the corolla tube is
longer than the obtuse sepals and bracteoles; anthers are without sterile tips and extend beyond the corolla; the ovary has
5 cells; and, the style is long, slender and lacks hairs.
Flowering Period:  October
Distribution and Habitat
The type of 
Leucopogon breviflorus held at Kew is a mixed collection of specimens collected by George Maxwell last
century.  One was collected near Israelite Bay and the other from the Stirling Range.  The 'Israelite Bay' 
L. breviflorus is
widespread in the Goldfields and Esperance Districts where it usually occurs in rocky areas growing in red-brown clayey
sand; as well, it has been found in white aeolian sand near a small lake, and in deep yellow sand.  It occurs in mallee,
open shrub or thicket communities.

Summary and Recommendations
L. breviflorus has been poorly known and difficult to identify taxonomically.  It appears to be widely scattered through
the South Coast and Goldfields Regions and should remain secure in two Nature Reserves and one National Park.
Taxonomic work to lectotypify the species and confirmation of herbarium specimens is required (J. Powell, personal
communication).

Leucopogon interruptus R.Br.
EPACRIDACEAE
A shrub to 1.5 m tall with erect branches.  Leaves are mostly crowded at the end of each year's shoot, apparently in
whorls, almost oval to oblong-elliptical (about 25 mm long), flat, hairless and finely nerved.  Clusters of flowers (spikes)
are at the ends of branches, slender and interrupted, but not exceeding the leaves.  Flowers are small and numerous;
bracts and bracteoles are less than half the length of the calyx; the corolla tube is shorter than the calyx; the ovary is
globular, 5-celled and the style short.
Flowering PeriodAugust - September
Distribution and Habitat
Leucopogon interruptus is known only from a few islands in the Archipelago of the Recherche and from Mt Manypeaks
east of Albany.  It grows in grey sand over granite rocks in mixed vegetation of dense shrub mallee and 
Allocasuarina-
