Xysmalobium prunelloides Turcz.

Plant 6-9 in. high, branching at the base only into numerous stems, which are roughly pubescent along two broad lines; leaves 3-7 pairs to a stem, 1-2 in. distant, spreading; petiole 1.5-2.5 lin. long; blade 0.5-1.25 in. long, 4-7 lin. broad, ovate, acute, broadly rounded, slightly subcordate or occasionally broadly cuneate at the base, flat, rather thinly covered with rather soft spreading hairs on both sides; umbels solitary on each branch, terminal, pedunculate, 14-30-flowered, hemispherical or subglobose, about 1 in. in diam.; peduncle usually 2-3 in. long, in weak specimens much shorter, erect, thinly covered with spreading hairs, and often with a minute pubescence besides; bracts about 1.5 lin. long, subulate, deciduous; pedicels 3-4.5 lin. long, pubescent with spreading hairs; sepals 1-1.25 lin. long, 0.33-0.5 lin. broad, lanceolate, acute, pubescent; corolla about 2.5 lin. in diam., glabrous inside, thinly pubescent with rather long spreading hairs outside, brownish or greenish-brown; lobes 1.5-1.75 lin. long, 1 lin. broad, ascending, elliptic, subobtuse; corona-lobes arising slightly above the base of the staminal column, and reaching to about the same level, slightly divergent-spreading, 0.66-0.75 lin. long, 0.25 lin. to rather more than 0.33 lin. broad, linear-oblong to narrowly ovate, obtuse, rather thick and fleshy, in the dried state they sometimes appear to be slightly keeled down the inner face, probably due to shrinkage in drying; staminal column 0.75 lin. long; anthers quadrate, their appendages suborbicular, inflexed over and nearly concealing the truncate apex of the style; follicles not seen.
