Eriochlamys cupularis N.G.Walsh
Family Asteraceae
Eriochlamys cupularis N.G.Walsh APNI*

Description: More or less erect annual, 7–20 cm high, sub-shrubby; stems white-cottony on newer growth, usually glabrescent on older parts.

Leaves linear, 2–11 mm long, 0.3–0.8 mm wide, narrowly to widely spreading from stem, obtuse or rounded, base shortly decurrent, margins revolute, entirely obscuring the abaxial surface, adaxial surface glabrous or with few scattered sessile glands, abaxial midrib usually with spreading cottony hairs near base.

Flowerheads solitary, cupular, 2.5–3.8 mm long, 2.5–3.5 mm diam.; bracts in 2–3(–4) rows, outer bracts linear, subequal to or slightly exceeding capitulum, leaf-like; medial bracts broadly elliptic, 1.5–2.8 mm long, moderately to densely cottony, sparsely glandular near middle (but glands often obscured by hairs), entirely herbaceous or with narrow membranous margins, apex truncate, sometimes recurved, ciliate; inner bracts obovate, as long as capitula, entirely membranous or with a narrow central stereome. Florets 20–50 per flowerhead, slightly exceeding involucre at maturity; tubular part of corolla 1.3–2.1 mm long, with scattered glands and cottony hairs concentrated proximally and distally or distal hairs sometimes absent; lobes spreading or recurved, 0.3–0.4 mm long.

Achenes obovoid, truncate or slightly depressed at apex with a short apiculum, 0.55–0.65 mm long, 0.3–0.35 mm diameter.

AVH map***

More closely related to E. squamata than other members of the genus. See notes under that species (above). The epithet is Latin, meaning ‘cup-shaped’, and refers to the shape of the capitula which are more distinctly cup-shaped in this species than other members of the genus.
