Susceptibility to Phytophthora Dieback
Unknown
Summary and Recommendations
E. litorea appears to be common near Israelite Bay, although a portion of this population occurs in the camping area and
is therefore very vulnerable to fire and clearing for fuelwood.  There appears to be two age structures of this population,
indicating that a fire may have burnt the sector between the fisherman's buildings and the camping area some years ago.
The population on the north side of Daringdella Lake was not relocated during a survey in April 1992; parts of this area
were burnt in October 1991.  Monitoring of the known populations and further survey along the south side of
Daringdella Lake towards Point Malcolm is required.

Eucalyptus misella L.A.S.Johnson & K.D.Hill
MYRTACEAE
A low, rounded dense mallee, to 3 m tall, with smooth or matt bark of variable colour.  Foliage is dense and extends to
the ground.  Adult leaves are alternating, lanceolate (60-100 x 7-10 mm), held erect, at first dull, blue-green maturing
glossy green; veins are dense with very numerous intersectional oil glands.  Clusters of 7 flowers are unbranched and
borne on rounded or angular stalks (peduncles, 2-8 mm).  Buds have short stalks (pedicels) and are egg-shaped (5-7 x 3-
5 mm); bud caps are bluntly conical and narrower than the calyx tube at the join; stamens in the buds are first erect then
bend strongly downwards.  Flowers are white.  Fruits are hemispherical to conical in shape (4-5 x 6-7 mm) with a thick
rim and a ring-like disc raised free of the 3 enclosed valves.  Seed is red-brown and smooth with longitudinal grooves.
Eucalyptus misella is similar to E. angustissima but differs in its wider leaves, longer peduncles and enclosed valves.
Flowering Period:  August - October
Distribution and Habitat
E. misella has a scattered distribution from west of Grass Patch to east of Scaddan, a geographic range of about 80 km.
It grows on sandy clays and loams, often near salt lakes or on alluvial flats near saline creeks, and in flat, sandplain
heath country associated with 
E. tetragona.

Summary and Recommendations
The majority of known populations are on road reserves in areas where land has been cleared for agriculture.
Surveys along Scaddan Rd failed to relocate two sub-populations (nos. 1b and 1c) (the species was originally confused
with 
E. rigens, also a low, rounded mallee occurring around salt lakes), the third (pop. no. 1a) is on a degraded road
reserve which is weed invaded, providing little chance for growth of seedlings.  This sub-population is vulnerable in the
long term.  Road markers are required.

257
A survey for the Griffiths Rd population (no. 4) failed to relocate this species.  The road reserve is extremely degraded
with few native plants remaining; the private property abutting the road is largely cleared and the vegetation remaining
around the salt lakes is grazed.  Consequently, this population may have disappeared.  
Further survey is urgently required.  
E. misella is not known to occur in any conservation reserve.

Eucalyptus pterocarpa C.A.Gardner ex Lang
MYRTACEAE
A small tree, 10-14 m tall, with smooth, grey over salmon to copper-coloured bark.  Adult leaves are alternate,
lanceolate (85-170 x 12-30 mm), dull blue-green at first maturing glossy, bright green; the veins are very dense and
thick.  Clusters of 3 flowers are unbranched and borne on angular to flattened stalks (peduncles, 7-15 mm).  Buds (17-21
x 10-15 mm) are stalked (pedicellate) and strongly ribbed all over; stamens in the bud are first erect then strongly
downturned.  Bud caps are conical to slightly beaked.  Flowers are white.  Fruits are conical (13-18 x 14-17 mm),
strongly ribbed with a thick rim, descending disc and 4 valves at rim level.  The seed is ruby-red to red-brown and shiny.
The strongly ribbed buds and fruits which are a distinguishing feature of 
Eucalyptus pterocarpa are similar to those of
E. lesouefii and E. corrugata.  However, the latter two species have rough bark at the base; E. lesouefii has up to 9-
flowered clusters and 
E. corrugata has flattened bud caps and grey seed.
Flowering Period:  September - November
Distribution and Habitat
E. pterocarpa is distributed over about 90 km to the west and north-west of Norseman.  It grows in red-brown loam in
open low woodland with 
E. salmonophloia, E. dundasii, E. calycogona and E. flocktoniae and undershrubs of Acacia
merrallii.

Summary and Recommendations
E. pterocarpa occurs in a poorly surveyed area of Vacant Crown Land which is largely inaccessible.  A timber reserve
north-west of Norseman, that would include 
E. pterocarpa and E. brockwayi, has been proposed (Henry-Hall 1990).
Further action on this proposal and further survey is required.

Eucalyptus spreta L.A.S.Johnson & K.D.Hill ms
MYRTACEAE
A tree or mallee to 10 m tall, with erect branches from low on the trunk.  Bark is smooth and coloured white, grey,
salmon or bronze.  The adult leaves are shaped like the blade of a scythe (falcate, up to 110 x 10-13 mm), semi-glossy,
narrow, bright darkish green and held erect.  The axillary inflorescences are up to 7-flowered; stamens are at first erect
then bend downwards in the bud (13 x 4-6 mm) and a scar is left when the bud cap falls.  Fruits are cup-shaped.
Eucalyptus spreta ms is related to E. pileata and E. polita but can be distinguished from them by its strongly beaked bud
cap and from the latter by having larger buds.
Flowering Period:  ?October - November
Distribution and Habitat
E. spreta ms has a scattered distribution from near Balladonia to south of Peak Eleanora, a range of about 250 km.  It
grows in a variety of habitats including almost flat plain, margins of salt lakes, or amongst granite rocks in calcareous
red-brown loam, clay loam, sand or white sandy loam.  It occurs in low open woodland either as a pure stand or with 
E.
diptera, E. eremophila, E. calycogona, E. cylindriflora or E. flocktoniae.

Gastrolobium heterophyllum (Turcz.) Crisp
PAPILIONACEAE
[ex. 
Oxylobium heterophyllum (Turcz.) Benth.]
Slender Poison
A trailing rather than erect shrub with weak slender stems.  The conspicuous, fine stipules (appendages at the base of the
leaf stalk) are longer than the leaf stalks.  Leaves are opposite, narrow-oblong (15-30 x 2-4 mm), with slightly inrolled
margins underneath, and a fine spine at the tip; the upper surface is dark green, hairless and has a conspicuous network
of veins, while underneath is paler with spreading hairs especially along the midrib.  Hairs are absent on the older
foliage.  Flowers are yellow suffused with purple-red and borne in short, elongate clusters (racemes) at the ends of
branches; the acute bracts persist until the flower opens.  Seed pods are elliptical (about 5 x 4 mm) with a fine, long
spine at the tip; 6-8 seeds are borne per pod.
Gastrolobium heterophyllum has similar leaves and flowers to the widely distributed Box Poison, G. parviflorum.  The
latter species is always erect, has longer racemes with more flowers, more robust stems and less conspicuous stipules
than 
G. heterophyllum.
Flowering Period:  September - October
Distribution and Habitat
G. heterophyllum is distributed between the Fitzgerald River and Esperance, a range of about 200 km.  It grows in
gravelly soils near rivers and in red clayey soils on flats.  Associated species may include 
Eucalyptus preissiana or
Melaleuca uncinata.

Response to Disturbance
Probably a disturbance opportunist.

262
Susceptibility to Phytophthora Dieback
Unknown
Summary and Recommendations
G. heterophyllum is widespread, but never common.  It may be an opportunistic species that is most often seen after
disturbance.  In September 1993, a new population was found near the Young River in an area which had been burnt in
March 1990; plants were flowering.
A three-day survey by Sampson (in Sampson and Hopper 1990), looking specifically for endangered 
Gastrolobium
species in the eastern south coast region, failed to locate any populations of this species.  Previous surveys may have
failed to find this taxon as herbarium specimens suggest that 
G. heterophyllum should look like a slender form of
G. parviflorum; in fact, it is more reminiscent of Chorizema.
G. heterophyllum apparently occurs in both the Stokes and Fitzgerald River National Parks, although it has not been
sighted recently.  Further opportunistic survey is recommended.

Gastrolobium rigidum (C.A.Gardner) Crisp
PAPILIONACEAE
[ex. 
Oxylobium rigidum C.A.Gardner]
Rigid-leaf Poison
A low, spreading shrub, usually about 30 cm tall, but one form grows to 90 cm.  Stems arise from a woody rootstock and
are repeatedly forked.  Leaves are opposite, oblong-elliptical (10-30 x 10-15 mm), rigid, blue-green, have short stalks
and a prominent yellow midrib.  Flowers are yellow suffused purple-red and borne in small, elongate clusters at the ends
of branches.  The pods are silky-hairy.
Flowering Period:  October - November
Distribution and Habitat
The typical form of 
Gastrolobium rigidum is distributed over about 100 km, from Lake Varley to near Mt Short.  It
grows in sandy clay, gravel and loam in low heath communities with scattered mallees of 
Eucalyptus phaenophylla.
Aplin (1973) indicates that a larger form occurs in the mallee country around Tarin Rock.

Susceptibility to Phytophthora Dieback
Unknown
Summary and Recommendations
G. rigidum is very common along disturbed road and track verges on the east and west side of the Vermin Proof Fence,
from Mt Gibbs southwards to the Lake King-Norseman Road, including the Frank Hann National Park.  It is secure in
this National Park, and is not immediately threatened in the Crown Land to the north of the Park.
The deletion of 
G. rigidum from the Priority Flora List is recommended, although some monitoring may be required of
the larger form that grows near Tarin Rock.

Goodenia quadrilocularis R.Br.
GOODENIACEAE
An erect herb, 0.5-1.5 m tall, with few branches.  Leaves are lanceolate to obovate (50-70 x 10-15 mm), shiny, bright
green and have toothed margins.  Yellow flowers are in elongate clusters (racemes) at the ends of branches, and borne
on stalks in the axils of bracts.  The base of the calyx has small, linear bracteoles.  The corolla is sparsely hairy; the 2
upper corolla lobes are separated much lower than the 3 lower ones.  Fruits are narrow, elongate (about 2 cm long) and
have 4 locules.
Flowering Period:  September - November
Distribution and Habitat
Goodenia quadrilocularis is known only from near-coastal granite rocks in the Cape Arid and Cape Le Grand National
Parks, which are nearly 100 km apart.  It grows in skeletal soils in rock crevices, often exposed to salt-laden winds.

Response to Disturbance
On Mt Arid, this species had flowered and set seed two years after being burnt (January 1991).  The abundance of
G. quadrilocularis post-fire suggests that it may be a coloniser of disturbed sites, becoming less common as plant
communities mature.
Susceptibility to Phytophthora Dieback
Unknown
Summary and Recommendations
G. quadrilocularis has a very restricted habitat and narrow geographical range.
At present, this species is secure within the two National Parks.  Further survey is recommended between Cape Le
Grand and Cape Arid.
