Pectinaria

Dwarf, mat-forming, leafless, glabrous, succulent perennials. Stem usually procumbent, often arching and rerooting as it elongates, 6-angled, tuberculate-tesselate, acutely toothed along angles when young, often with a distinct bud in axil of each tubercle. Flowers solitary of rarely in pairs, arising between angles near stem apex. Sepals lanceolate, acuminate. Corolla: tube cupular or campanulate; lobes ovate-lanceolate to lanceolate, usually connate at apex. Corona 2-seriate, glabrous; outer lobes bifid into 2 slightly diverging, erect to semi-erect horns, joining to dorsal projection of inner lobes; inner lobes adnate to backs of anthers; dorsal projections divided into many semi-erect processes forming a pectinate ring with outer lobes. Anthers 2-locular, without apical appendages. Pollinia suberect or nearly horizontal, broader than long, with short caudicles and winged corpuscle. Follicles erect, terete-fusiform, glabrous, smooth. x = 11.
