Patersonia spirafolia Keighery

IRIDACEAE

This species was first described in 1990 and is known from five collections, the earliest made in 1984.

It is a perennial herb to 50 cm tall, with a spreading woody rootstock producing a tussock to 40 cm across.

The leaves are linear, up to 20 cm long and 5 mm wide, spirally twisted. The leaf margins have fringes of

soft hairs which point towards the centre of the leaf.  The spathe is up to 25 cm long, 1-2 mm wide.  It is

brown, with thin, almost transparent margins, and is lanceolate in shape and up to 26 mm long.  The

flowers have three broad, spreading sepals to 19 mm long and 14 mm wide, blue-violet in colour.  There

are three upright blue-violet petals about 1 mm long.  The three yellow stamens are 7-8 mm long and the

style has three stigmatic lobes.



Patersonia spirafolia is related to two other species which form tussocks.  It differs from P. inaequalis in

the purple rather than white flowers and brown rather than green spathes, and from 



P. drummondii in the

fringed leaf margins and shorter brown spathes. 



Flowering Period:  October-November

Distribution and Habitat in the Moora District

It has been recorded from a very restricted range of less than 10 km in the Badgingarra area, where it grows

in sand over laterite in low heath.

Persoonia chapmaniana P.H.Weston

PROTEACEAE

A rounded shrub to 2 m in height, with stiff, terete, linear leaves with sharp points and five longitudinal

grooves.  They are 2-8 cm long, 0.9-1.3 mm broad, often crowded.  The flowers are borne in terminal or

axillary racemes from the axils of small triangular scale leaves, 0.5-2 mm long.  There are 5-30 flowers in

each raceme.  The flowers are divided into four bright yellow, glabrous tepals each of which is recurved in

the upper part and has an anther inserted just below the middle.  Each anther has a whitish, globular

appendage.  The ovary is hairy and the style projects beyond the tepals.  The fruit is a warty, elongated

drupe, with a succulent outer coat.

Persoonia chapmaniana is distinctive, resembling only P. pentasticha which occurs further north, and from

which it differs in the densely hairy ovary, and glabrous tepals.



Flowering Period:  September-November

Distribution and Habitat in the Moora District

Has been found recently between Moora and Three Springs and is also known from outside the Moora

District between Kalannie and Kulja on the west side of Lake Moore in the Merredin District.

Grows on yellow sandy loam over clay or white to grey sandy clay, in York gum woodland, in open scrub

or in open, low woodland of 

Banksia and Actinostrobus species, usually near lakes.

Persoonia filiformis P.H.Weston

PROTEACEAE

[

Persoonia sp. Eneabba (E.A.Griffin 795)]

A small, lignotuberous shrub to 30 cm tall with several erect stems.  The leaves are terete, ribbed and stiff

with sharp tips.  They are ca. 1-2 cm long, and ca. 0.7-1 mm broad.  They are erect and crowded on the

branches.  The hairs on the young shoots are less than 1 mm long, the mature shoots become glabrous.  The

flowers are narrow, glabrous on the outside, ca. 15 mm long, yellow in colour.  The anthers have

appendages, which are triangular at the base, narrowing to a filiform, often sinuate tip 2-4.5 mm long.  The

appendage is abruptly reflexed through 90-180 degrees.  The ovary is glabrous, the style is thick and

straight with a thickened stigma, and is about as long as the stamens.

The name 

filiformis refers to the threadlike anther appendage, which distinguishes this species from all

others in the genus.



Flowering Period:  November, January

Distribution and Habitat in the Moora District

Occurs from the Arrowsmith area to the Lesueur area, and south to Badgingarra. 

Grows in white sand over lateritic gravel, or yellow sandy gravel, in low open heath sometimes on the

upper slopes of mesas.

This taxon came to notice during the course of this survey, so was not specifically searched for.  There are

large areas of uncleared suitable habitat throughout its range.

Podotheca uniseta P.S.Short

ASTERACEAE

An annual herb with ascending to erect main stems.  The leaves are linear, to 4.5 cm long, succulent and

green, red or purple in colour.  The flower heads are distinct, up to 2.8 cm long, cylindrical in shape.  There

are tubular florets only and the flower head is surrounded by outer involucral bracts which are herbaceous,

appressed, and linear to lanceolate in shape.  The florets are mainly yellow in colour, with the upper part of

the tube usually purple.  The fruit is an achene up to 1.9 mm long.  It has one pappus bristle at its apex, not

five as in other species of 



Podotheca.  This separates the species from P. pritzelii which also has more

succulent outer herbaceous bracts around the flower head, which are bright green, not tinged purple. 



 P.

gnaphalioides is also difficult to separate except by the number of pappus bristles but there is an ecological

difference in that at the type locality it grows mainly under



 Melaleuca, extending only to the outer edge of

the samphire zone where it grows with



 P. uniseta.

Flowering Period:  September-November

Distribution and Habitat in the Moora District

In the Moora District, this species has been reported as occurring in a sandy area near a small lake in a

nature reserve west of Marchagee.  This population was not refound during the survey. 

Has been collected from Lake Monger and south of Morawa in the Geraldton District and from the eastern

edge of Lake Moore and from south of Pithara in the Merredin District.  The total distribution range for the

species is ca. 130 km.

In populations known from other districts it has been found growing in the samphire zone around saltlakes,

on pale red sandy loam, grey or white coarse sand/clay or gravelly loam, sometimes extending into the



Melaleuca shrub zone.  In the Moora District it occurs on flats or depressions in woodland of Eucalyptus

camaldulensis, or low scrub with hummock grasses.

Stenanthemum grandiflorum (C.A.Gardner) Rye ms

RHAMNACEAE



Stenanthemum grandiflorum ms is a low shrub 0.3-0.6 m tall.  The leaves are alternate and grow mainly on

the young branches.  They are narrow and folded with a recurved, acute tip and are 6-15 mm long.  The

flowers are grouped in clusters, ca. 1 cm in diameter, surrounded by broad, overlapping, sharp-pointed

bracts which are brown in colour.  Each flower has a short but distinct stalk.  The calyx is covered with

fine, silky hairs, and is 6-7 mm long, tubular above the ovary and disc with five acute lobes ca. 2.5 mm

long.  There are five petals, hood-shaped, enclosing the anthers.  They are white to pink in colour, 0.75 mm

long.  The ovary is three-celled and inferior and the fruit is a capsule opening by two valves.

This species was described by C.A. Gardner in 1942 as 



Cryptandra grandiflora.

Barbara Rye has reinstated the genus 



Stenanthemum as originally described by Reissek including elements

of 


Cryptandra and Spyridium, not included by Bentham in 1863; however further taxonomic research is

required for this species.



Flowering Period:  August-September

Distribution and Habitat in the Moora District

One population was found during the survey near Watheroo and the species has been collected in 1968 near

Coorow, 45 km to the north.  Another collection made in 1968 indicates that the species has occurred

further west between Watheroo and Eneabba.  A collection made in 1947 at Wongan Hills is ca. 90 km

south-east of the only recently surveyed population, so that the species has had a geographic range of at

least 120 km in the past. 

The population found during the survey was growing in yellow-brown sandy loam with granite, amongst

low open scrub to 1.5 m and low heath to 0.5 m on south-east facing gentle slopes.  Associated species

included 

Hypocalymma  sp.,  Acacia sp. and Grevillea christineae.  It has also been recorded growing in

grey sandy soil.

This species is represented by seven collections in the Western Australian Herbarium and had not been

collected for 25 years until found near Watheroo late during this survey.  As it had not been included in the

list for the District previously, more survey work is required in the Moora District and also in the Merredin

District where it was collected at Wongan Hills in 1947.

Stenanthemum limitatum Rye RHAMNACEAE

This species was known as 



Cryptandra sp. (Lesueur) A.S.George 12893 until a recent taxonomic revision

by Barbara Rye who has reinstated the genus 



Stenanthemum Reissek.

S. limitatum is an erect to spreading shrub, to 1 m tall but usually shorter.  The simple leaves are 6-17 mm

long, 3-8 mm wide, on short stalks to 1 mm long.  They are widest at the tip, narrowing towards the stalk.

The tip is indented giving the leaf a heart shape.  In colour the leaves are dark green above, with a pale,

densely-hairy lower surface.

The short-stalked flowers are clustered in the axils of the leaves.  They are cream to white in colour, with a

petal tube ca. 2.5 mm long with five spreading lobes ca. 1.5 mm long.

The specific name refers to the limited range of the species.

Flowering Period:  October-November

Distribution and Habitat in the Moora District

This species has been collected from three localities over a range of 8 km to the east of Jurien Bay.  It

grows in low woodland over open low heath, in grey sand with lateritic duricrust and gravel, grey-orange

sandy lateritic gravel and sandy loam, and in white sand over sandstone, at the upper edge of breakaways.
