Verticordia dasystylis A.S.George subsp . oestopoia A.S.George
MYRTACEAE
A dwarf, mounded, single-stemmed shrub to 30 cm high and 60 cm wide. The leaves are oblong
to elliptic in shape, blunt at the apex, 1.5-4 mm long. They have margins that are irregularly
toothed or are edged with fine bristles. The flowers are on stalks 3-6 mm long and they are pale
creamish-lemon to bright yellow in colour. The sepals are intricately divided into wide
spreading, fringed lobes and are 6-7 mm long. Each petal is fringed and is 3 mm long.
This subspecies differs from the other subspecies in that the linear staminodes are shorter, only
0.7 mm long, whereas in the others they are 1.2 mm or longer. The anthers are globular and the
style is 8 mm long with white hairs for up to three quarters of its length.
This species is related to
Verticordia penicillaris from which it differs in its smaller size and more
hairy style. The specific name means hairy or shaggy style. This subspecies was known only
from the Arrowsmith area when it was named in 1991, the name “
oestopoia” is from the Greek
for arrow and to make or work, in reference to the name Arrowsmith.
Flowering Period: October-early November
Distribution and Habitat in the Moora District
This taxon was originally collected from a few kilometres south of the Arrowsmith River north-
east of Eneabba within the Moora District. It has not been refound at this location and is now
known from two small populations west of Bunjil, ca. 5 km east of the Moora District boundary
in the Geraldton District and ca. 60 km east of the original collection.
Grows in shallow soils of yellowish-grey clay loam or yellow-grey sand over granite in open
shrubland with associated species including
Melaleuca radula, Acacia uncinata, Mirbelia
ramulosa, V. monadelpha and Dodonaea sp.

Verticordia fragrans A.S.George
MYRTACEAE
An erect shrub 1 to 3 m tall, with open branching. The leaves are orbicular to elliptic and entire
in shape, 1.4-4 mm long, the bases partly stem clasping. The flowers are borne on thick stalks in
dense spikes towards the ends of the branches. They are pink and white in colour, both sepals
and petals being pink at the base and white above so that the flowers are dark pink at the centre.
They have a sweet honey scent. The hypanthium is warty glandular and hairless with five green
broad, thick appendages from the apex. The sepals are 3.5-4 mm long, with 6-9 broad, plumose
lobes and basal auricles covering the hypanthium. The petals are 4-4.5 mm long with small basal
auricles. They are 4-4.5 mm long, orbicular in shape, erect and entire with cilia towards the base.
The stamens are 3.5 mm long and the staminodes are oblong, acute and incurved, 3-3.5 mm long.
Verticordia fragrans differs from closely related species in its pink and white, fragrant flowers,
the broad sepal lobes, and entire upper margins of the prominent petals.
Flowering Period: Late September-November
Distribution and Habitat in the Moora District
In the Moora District this species is known from a few populations to the north and south of
Eneabba and one population further south in the Coomalloo area. A collection made in 1959 of
uncertain location may be from Dinner Hill, which is ca. 25 km south-east of this, or from
Mullewa in the Geraldton District. A recent report of the species has been made from just south
of Mullewa so it seems more likely to be the latter.
Grows in deep, white, grey to yellow sand with lateritic gravel beneath or in sandy clay loam in
tall shrubland, sometimes with open low woodland of
Eucalyptus todtiana and Banksia attenuata
with open heath. Associated species include
V. aurea, V. laciniata, V. grandis and V.
monadelpha.

Verticordia luteola A.S.George
MYRTACEAE
var
. rosea E.A.George & A.S.George
This variety was described in 1994 after its discovery north of Eneabba by A. Tinker.
It is an upright, slender shrub to 1.5 m. The leaves are obovate and erect, 3-4 mm long on the
main stems, and more crowded and spreading and 2-2.5 mm long on the side branches. The
flowers are borne in racemes, on short stalks. The hypanthium is deeply three-ribbed and has
reflexed green appendages. The sepals are greenish-pink with a silver fringe, becoming lemon-
cream, 4.5-5.5 mm long, with 7-8 fringed lobes. The petals are bright pink with a pale pink or
white fringe which is further fringed. They are 6-6.5 mm long, the fringe is 3 mm long. There
are acute, glandular staminodes, slightly shorter than the stamens. The style is 5-6 mm long with
a dense beard for ca. 1 mm.
Verticordia luteola var. rosea differs from the typical variety in the flower colour, which is pink,
not yellow. It flowers later, has slightly larger leaves, a longer petal fringe, and longer stamens
and staminodes. It occurs further to the west and south-west of the distribution of
V. luteola var.
luteola.
Flowering Period: December-January
Distribution and Habitat in the Moora District
Known from an area north of Eneabba over a range of ca. 6 km.
It grows in deep white sand in low heath to 1 m with very open low woodland of
Eucalyptus
todtiana, Banksia attenuata and B. menziesii, associated species including Allocasuarina humilis,
Calothamnus sp. and Jacksonia sp.

Verticordia spicata F.Muell. subsp . squamosa A.S.George
MYRTACEAE
Spiked Featherflower
The subspecific name means scaly, referring to the small overlapping leaves.
Verticordia spicata subsp. squamosa is a shrub to 80 cm tall and 1 m wide with a compact, dense
habit. The leaves are 1.5-2 mm long, rounded to elliptic, with prominent oil glands. Their
margins are irregularly toothed or fringed with hairs less than 0.5 mm long. They are pressed to
the stem and closely overlapping. The flowers are closely packed, forming dense spikes on the
ends of the branches. They are mauve pink in colour fading to white and are stalkless or with
short stalks. The hypanthium is honeycombed with obscure ribs and has 5 green reflexed
appendages nearly as long as the tube.
The sepals are 3-4 mm long, fringed and with small basal auricles. The petals are 3 mm long,
fringed with fine segments more than 1 mm long. The stamens and staminodes are hairless and
the staminodes are linear. The style is 4 mm long, and bearded below the apex.
Differs from
V. spicata subsp. spicata in the smaller leaves and flowers. At the type locality V.
spicata subsp. squamosa grows with V. comosa and appears to hybridise with it. The presumed
hybrid has spreading leaves 2-3 mm long, a hypanthium with shorter appendages, sepals with
prominent auricles and a style 5 mm long with a more dense beard than that of
V. spicata subsp.
squamosa. Another presumed hybrid has "offwhite" flowers, with larger sepal auricles and a
style beard with longer hairs.
Flowering Period: October-December
Distribution and Habitat in the Moora District
Occurs between Three Springs and Morawa where it is known in the Moora District from two
small populations and three other populations which occur just within the Geraldton District, all
within a range of 17 km. Two of the latter populations have not been refound recently.
Grows in tall shrubland, in deep yellow sand. Associated species include
Eucalyptus jucunda,
Actinostrobus arenarius, Jacksonia sp., V. comosa, V. monadelpha, V. densiflora var.
stelluligera, V. eriocephala and Grevillea biformis.
The population on Simpson Road has declined over the last few years from 12 plants to two.
These are on a narrow, weedy road verge. Two plants of the hybrid between this subspecies and
V. comosa are also present.

Acacia anarthros Maslin
MIMOSACEAE
This species was originally described as
Acacia drewiana W.V.Fitzg. subsp. pungens Maslin in 1975 but
collections of the fruits made in 1976 provided sufficient additional information to raise the taxon to
specific rank in 1979.
A. anarthros is a dwarf shrub up to 1 m tall. The bipinnate leaves have decurrent leaf axes, each leaf has
one pair of pinnae, two to three pairs of pinnules and spiny stipules. The flower heads are globular, about 0
5 cm in diameter with less than 20 flowers per head. The pods are up to 6 cm long with seeds which are
dull, minutely roughened and mottled.
This species differs from
A. drewiana in its single pair of pinnae, the pungent terminal seta and somewhat
pungent stipules and the number of flowers in the head.
Flowering Period: May-July and September
Distribution and Habitat in the Moora District
A. anarthros is distributed over a geographic range of 55 km from south of Bindi Bindi to near Bolgart in
the Moora District and westward into the Swan Region north of Bindoon. It also occurs near Brookton in
the Narrogin District. It is now known from thirteen populations with a total of more than 2000 plants.
It grows beneath open woodland of
Eucalyptus wandoo and E. calophylla in low heath or scrub with
Hakea, Dryandra and Grevillea species. It occurs in sand, gravelly loam and gravel.

Acacia aristulata Maslin ms
MIMOSACEAE
An undescribed species,
Acacia aristulata ms is a shrub to 1 m tall which may be erect, spreading or
decumbent. The stems are slender and usually white. The light to mid-green erect phyllodes have recurved
apices and are 7-10 mm long x 2-3.5 mm wide. They may be glabrous or pubescent. The stipules are
prominent, 2-3 mm long. The flower heads are creamy-white, 5-6 mm in diameter on peduncles 10-20 mm
long. The legumes are constricted between the seeds, loosely once-coiled or irregularly twisted, to 6 cm
long and containing elliptic, shiny, grey seeds with a dark nerve.
This species is similar to
A. bidentata which has hairless phyllodes, smaller heads arranged in racemes and
smaller pods with uniformly coloured seeds. It is also similar to
A. rostellata which has somewhat pungent
branchlets, phyllodes with pungent tips, shorter peduncles, smaller heads and black seeds.
