Synonymy

Cyphanthera albicans subsp. notabilis Haegi, Telopea 2(2): 176 (1981) 

T: Timor Rock, Warrumbungle Ranges, N.S.W., L. Haegi 1379; lecto: CANB; iso: AD, K, L, MO, NSW.

Description

Erect shrub to 3 m, greyish. Branches granular-tomentose or pubescent with mainly dendritic, non-glandular hairs and scattered glandular hairs.  

Leaves elliptic to ovate-elliptic or obovate-elliptic, almost sessile, 15–25 mm long, 3–6 mm wide, tomentose; juvenile leaves to 13 cm long, 4 cm wide.  

Inflorescence panicle-like, dense, leafy; pedicels 1–6 mm long. Calyx 2–5.5 mm long, sparsely to densely pubescent. Corolla 13–22 mm long, glabrous outside, white, cream or pale yellow, the striations purple; lobes ovate-truncate to almost linear, 3–15 mm long. Stamens 2–5 mm long.  

Capsule globose to broadly ellipsoid, 2.5–8 mm long. Seeds 2.3–3.8 mm long.

Distribution and ecology

Endemic to the Warrumbungle Ranges in North Western Slopes region of N.S.W.  

Grows on rocky slopes in dark sandy soils derived from igneous rocks; common in shrub-land on exposed sites, but occurs sporadically in dry sclerophyll forest.

Common name

Grey Ray Flower

Notes

Distinction form other subspecies

Distinct from subsp. albicans by its longer leaves and corolla and distribution restricted to the Warrumbungle Ranges.

Distinct from subsp. tomentosa by its by its white or cream, rather than yellow, corolla and by the looser indumentum on the branches and leaves in which the hairs are 0.3-0.8 mm long, compared to the close tomentum of subsp. tomentosa in which the hairs are less than 0.3 mm long.

Phylogeny

Phylogenetic studies by Garcia & Olmstead (2003) on the Tribe Anthocercideae using two chloroplast DNA regions included this species The studies indicated that Cyphanthera is not monophyletic. Cyphanthers odgersii showed a closer relationship to Grammosolen while the rest of the Cyphanthera species combined to form a clade with Duboisia and Crenidium.
