Research Requirements - Further survey is required, in the Moora District to find new populations, and in the Swan Region and Narrogin District to refind and survey fully populations known from specimens at the Western Australian Herbarium. References George (1991). 149 Verticordia comosa A.S.George MYRTACEAE An erect open shrub to 2 m, with rounded, entire leaves, 2-4. mm long. The bracteoles are persistent. The flowers are pale yellow, the sepals are 4 mm long, with plumose lobes and peltate basal auricles covering the hypanthium. The petals are fringed, 4 mm long, with small basal auricles. The stamens have anthers attached basally with a swollen filament apex, the staminodes are channelled and flared towards the apex. The style is 4.5-5.5 mm long, with a one-sided and tufted beard, the hairs to 0.8 mm long. This species is related to
tips, the larger sepals and larger fringed petals and shorter style with tufted beard. The two species occur in separate areas.
Occurs over a range of ca. 25 km between Three Springs and Morawa on the north-eastern border of the Moora District and extending north into the Geraldton District. Has been recorded growing in deep yellow sand, yellow clayey sand, loamy sand over gravel and in greyish-yellow sand over gravel, in heath, open scrub and open woodland. Associated species include

George (1991). 151 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
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 “
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

Research Requirements - Further survey is required, particularly in suitable habitat south of the Arrowsmith River. References George (1991). 153 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.
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.

George (1991). 155 Verticordia luteola A.S.George MYRTACEAE var
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
