basally, with a typical bilobate callus at insertion of the leaf; stipules caducous. Inflorescence a terminal raceme, densely pubescent, rachis conspicuously bracteate, bracts subpersistent, linear, attenuate-acuminate, about 1 cm. long, lightly pubes- cent. Flowers pink, small, congested; calyx campanulate, densely pubescent with- out and very dark-hirsute-setose at insertion of pedicel and on main longitudinal ridges, glabrous within except at the base, thickly coriaceous, 15-ridged, about 8 mm. tall and broad, sinuately 5-lobed, each lobe about 1.5 mm. long and bearing a conspicuous reflexed fleshy tooth about 5 mm. long, the teeth pubescent, ligulate- oblanceolate, attenuate apically, about 2 mm. broad at insertion with lobe and bearing there on each margin a conspicuous fleshy horn about 0.5 mm. long; petals obovate, about 2 cm. long, densely setose without, especially laterally and near the middle, within only on the claw, claw thick-fleshy, linear, about 9 mm. long and 2 mm. wide, internally densely brown-setose on the margin and thus ridged down the middle, glabrous at the base, with a fleshy ridge towards either margin sur- mounted by a prominent brown-setose auricle about 1.5 mm. long; stamens 10, all antheriferous, those opposite the petals smaller, about 5 mm. long, those alter- nate with the petals larger, about 6 mm. long; filaments fleshy, glabrous; anthers small, bilocular, ovate-lanceolate, about 1.5 mm. long on larger stamens and 1 mm. long on smaller stamens; ovary sessile, setose-hirsute, few-ovulate, with an oblique, cleft, more or less sessile stigma.

Note
|
This species is especially marked by the leaf characters; the condensed, promi- nently bracteate inflorescence; the unusual calyx teeth; the auricled petal-claw; the subsessile ovary and stigma; and the long red-brown general pubescence. It is close to B. Storkzii and B. obovata.
