Characteristics

Sprawling or scandent shrub or semi-climber, 1-8 m; stem angled or weakly ribbed, densely felted when young with ±appressed, shaggy hairs and sessile glands, glabrescent. Leaves alternate, broadly ovate to lanceolate, 15-70 x 5-40 mm, 3-nerved from base, acuminate, base cuneate and shortly decurrent on petiole or abruptly cuneate, margins entire or weakly and distantly serrate, discolorous, upper surface green and felted-puberulous, lower surface densely whitish-felted with shorter, erect hairs mainly on veins and margins, and sessile glands, petiole 5-20 mm long. Capitula in globose clusters on divaricate branches in upper axils, forming cymose panicles, 15-to 20-flowered, sweetly scented. Involucre campanulate or obconic, 4-5 mm diam., bracts ±4-seriate, imbricate, thinly pubescent or subglabrous, margins membranous, ciliate, outer bracts lanceolate, acuminate-apiculate, ±3 mm long, inner oblong-lanceolate, 4-5 mm long, acuminate, 3-veined. Florets orange-yellow, 6-7 mm long, corolla tube narrowly funnel shaped, lobes linear, recurved, ±2 mm long. Anthers sagittate, ±2 mm long. Style up to 7 mm long, pilose or shortly hirsute distally and on branches, branches ±2 mm long. Cypselas narrowly obovoid to cylindric, angled or 6-to 10-ribbed, 1.5-2.5 mm long, silky with sessile glands; pappus biseriate, buff, scales 0.5-0.8 mm long, bristles 6-7 mm long, acute.
