Sebaea sedoides Gilg

Herbs with annual, erect or ascending, simple or branched stems from a perennial rootstock, up to 65 cm high. Leaves up to 2.5 cm long and equally broad, broadly ovate, reniform-cordate or reniform-orbicular, rounded to subobtuse, sometimes apiculate; or up to 1.5 cm long and 6 mm broad, rhomboid-ovate to ovate-lanceolate, cuneate at the base, obtuse or subacute, apiculate; the upper leaves generally smaller and further apart. Inflorescence a dense small or large corymb, sometimes much contracted and head-like with relatively large bracts immediately below, or paniculate-corymbose, densely many-flowered; bracts ovate to lanceolate, or narrowly obovate to oblanceolate, obtuse to acute, erect. Calyx of 5 segments, each 3-8.25 mm long, 0.75-2.75 mm broad, lanceolate, elliptic-lanceolate or linear-oblong to ovate, rarely somewhat obovate, acute or acuminate, mucronate, the sides hyaline or membranous-opaque and brittle when dry, joined for 0.25-1 mm at the base, keeled or with a very narrow keel-wing. Corolla yellow, butter yellow (fide Holt) or white (Galpin 13815); tube 3-8 mm long, often longer than the calyx; lobes 2.5-7.25 mm long, 0.75-3.25 mm broad, oblanceolate to orbicular-obovate, mostly rounded and apiculate, sometimes acute, clawed. Filaments very short to 1.75 mm long, inserted in or up to 1 mm below the corolla-sinuses; anthers 1-2.5 mm long, each with a small or medium, frequently stipitate, apical gland, and sometimes with 2 minute basal glands. Style and stigma 3.5-8.5 mm long, with a small or medium swelling below the middle, rarely without a swelling; stigma capitate or capitate-clavate, 2-lobed, often small.
