shrubby, robust; branches glabrous, densely leafy; leaves linear-subulate, acute, flat, 1–3-nerved, ciliato-serrate, shortly decurrent; pedunc. short, densely corymbose, pluri-bracteate, hispido-scabrous and glandular; invol. pluriseriate, scales many, linear-lanceolate, acuminate, roughly pubescent; achenes of ray with 1–3 barbellate bristles. This has the foliage of G. ciliare, but is much more robust and woody, with a very different inflorescence. Stems 1–2 f. high, branched above. Branches corymbose, leafy to the summit. Lvs. 1–1 1/2 inches long, 2 lines wide at base, somewhat gland-dotted, the wider ones obviously 3-nerved. Pedunc. many from the axils of the uppermost leaves, simple or branched, each bearing several subulate, scattered bracts. Achenes of ray black, 2-ribbed, glandularly granulated on the disc. Very similar in aspect to Mairea corymbosa, which has however a very different involucre and pappus.
