Characteristics

A vigorous shrub, 0.3-1.5(-2.5) m high, glabrous or almost glabrous, strongly resiniferous, moderately branching from the base; branches erect or ascending, usually straight, seldom drooping, leafy towards the ends, becoming nude. Leaves suberect-erecto-patent or sometimes spreading, laxly to closely set, often imbricated, oblong-(narrowly) elliptic-lanceolate, sometimes rotund-obovate-broadly ovate-orbicular, 0.8-3 cm long, 0.3-1.5 cm wide, flat, entire, coriaceous, greyish green or glaucous, distinctly or faintly midveined and sometimes with 2-4 fainter lateral veins; leaf-margins smooth (rarely laxly and minutely denticulate or ciliolate); leaf-tips acute-obtuse or rounded, often apiculate, mucro-nate, or short-acuminate; leaf-axils minutely and often indistinctly woolly, glabrescent. Peduncles lateral in the upper leaf-axils, few-many on each branch, (0.2-)0.5-6 cm long, 0.5-1.2(-1.5) mm thick, terete or striate, sometimes with two lateral rudimentary leaves in the axil. Involucre hemispherical, 0.5-1.5 cm in diam., 2-8 mm high. Involucral bracts subuniseriate-subbiseriate, (5-)6-11, connate to 1/4-1/3(-1/2); the free lobes narrowly-broadly ovate, often partly overlapping, 2.5-6 mm long, 2.5-5 mm wide, herbaceous or sub-coriaceous, sometimes membranous towards the margins, with 5-8 usually distinct veins, acute-obtuse, with puberulous tips. Receptacle slightly or distinctly convex, alveolate with sometimes much produced pit-margins. Ray-florets 5-11, yellow. Tube 1-1.5 mm long, cylindrical. Lamina elliplic-obovate-oblong, 2.5-7 mm long, 1.8-3.5 mm wide, 4-11-veined. Style terete or somewhat flattened; style branches 0.5-1.5 mm long, truncate-obtuse. Disc-florets c. 30-75. Corolla 3-5.5 mm long. Tube 1-2.5 mm long, cylindrical. Limb (narrowly) campanulate, 2-3.2 mm long, lobed to 1/4-1/3. Anthers 1.4-2 mm long inch the obtuse ovate appendage. Style terete with swollen base on a distinct stylophore; style branches 0.5-1 mm long, truncate. Pappus bristles numerous-copious, 1-3 mm long, white, distinctly barbellate, sometimes almost subplumose, often some reflexed. Achenes oblong-obovate-narrowly obovate, sometimes pyriform or clavate, 2.5-5 mm long, 1-2.5 mm wide, densely white or brownish lanate or villous, usually distinctly mucilaginous when soaked, with c. 5 ribs or nerves under the indumentum.
