Characteristics

Succulent, glabrous, perennial herb. Roots thin. Flowering stems annual, 5-10 cm long, 1.5-2 mm ø, simple, erect from nearly decumbent base, smooth. Leaves alternate (rarely opposite or ternate), remotely arranged, sessile, shortly spurred (the spur with a round-truncate apex, c. 0.5 mm long), entire, spathulate, apex round or obtuse, base long attenuate, 7—18(-27) by 2—5(-11) mm, thick-herbaceous, flat, smooth, spreading or ascending. Inflorescences terminal, a ternate bracteate cyme. Bracts leafy, spathulate to obovate. Flowers mostly 4-merous, erect, sessile. Sepals free, narrowly oblong-spathulate, base spurred (the spur with round-truncate apex, 0.2 mm long), apex round to nearly truncate, somewhat broadening towards the base, entire, somewhat unequal in size, 2-4 by 0.8-1 mm, more or less fleshy, green, smooth, suberect throughout, persistent at fructescence. Petals bright yellow, connate c. 0.3 mm from the base, lanceolate, acuminate, c. 4 mm by 1.2 mm, widely spreading at anthesis. Stamens 8, shorter than the petals, erect at anthesis; filaments filiform, 3-4 mm, oppositipetalous ones c. 1 mm from the base connate with the petal. Nectar-scales flat, narrowly oblong, 0.8 by 0.3 mm. Gynoecium 3-4 mm long, the ovaries basally for c. 0.5 mm connate, ven-trally gibbose, dorsally round, suberect, 1.5 mm wide at the middle, style very short, less than 0.3 mm. Ovules c. 20 in each locule.
