Sebaea macrophylla Gilg

Perennial herbs branched from the base and higher up, stiffly erect, ascending, or procumbent and straggly, up to 75 cm high. Leaves 0.6-2.1 cm long, 0.4-2.2 cm broad, subreniform, broadly ovate or cordate to suborbicular-ovate, sometimes broader than long, rounded or acute, often apiculate, membranous or coriaceous, margin sometimes reflexed; upper leaves sometimes narrower, ovate-oblong to ovate-lanceolate. Inflorescence often leafy, dense and many-flowered, or 1-several-flowered cymes terminal, on lateral branches or from the upper axils, or corymbose or paniculate-corymbose; bracts often foliaceous, ovate-cordate; in certain habit-forms smaller, ovate-lanceolate or lanceolate, spreading or recurved. Calyx of 5 segments (rarely 6-merous), each 5.5-9.5 mm long, 1.5-5 mm broad, lanceolate or elliptic to ovate or obovate, obtuse, acute or acuminate, mucronate, the sides hyaline to opaque and strawlike, often overlapping widely, joined for up to 0.75 mm, keeled or with a wing up to 1 mm broad, broadest at or below the middle. Corolla yellow; tube 5-9 mm long; lobes 5.5-11 mm long, 2.75-6 mm broad, oblong-oblanceolate to orbicular-obovate, rounded, sometimes apiculate, clawed. Filaments 1-2.75 mm long, inserted in the corolla-sinuses; anthers 1-3.75 mm long, each with a small to fairly big apical gland and usually with 2 smaller basal glands, very rarely apparently eglandular. Style and stigma 5-10 mm long, with a small to large stimatic swelling below the middle; stigma capitate or clavate, 2-lobed.
