Stamens inserted 0.7-0.8 mm above the corolla-base; filament 0.7-1.2 mm long, 0.3-0.5 mm broad at the base; anther 0.8-1 mm long, 0.5 -0.7 mm broad, 0.3-0.5 mm thick, obtuse at the apex, slightly cordate at the base. Ovary 0. 7-1 .3 by 0.8-1 mm, glabrous for lower 0.5-0.7 mm, short-hirsute in the upper part; stigma conical with 5 ridges

Sepals orbicular to transverse-oval, 3.8-5 by 4-5 mm, rather densely stellate-hirsute outside (hairs with 3-6 subequal, up to 500 µ long branches). Corolla creamy white, light yellowish, or light greenish, 9-10 mm, tube 3-4 mm; midpetaline field 4.3-5 by 2.8-3.2 mm, rather densely appressed-hairy (hairs usually with strong central branch, up to 1300 µ long, and 1- 3 smaller basal branches); lobules 3.2-3.5 by 2.5-4 mm, without distinct venation, slightly crenulate or undulate at the margin. Stamens inserted 0.8-1.2 mm above the corolla-base; filament 0.8-1 mm long, 0.5-0.6 mm broad at the base; anther 1:6 mm long, 0.6-0.8 mm broad , 0.5- 0.7 mm thick, narrowly acute at the apex (sterile for 0.2-0.6 mm), cordate at base. Ovary 0.8-1 by 1.7- 1.8 mm, glabrous; stigma conical, with 5 densely warty ridges.

Sepals rather densely stellate-hirsute outside (branches up to 500 µ long). Sepals 1 & 2 orbicular, 2.2- 2.3 by 2.2- 2.3 mm, 4 & 5 transverse-oval, 2.2-2.3 by 2.6-2.8 mm, 1 & 2 very sparsely stellate-hirsute (hairs with 3-6 subequal, up to 200 µ long branches), 4 & 5 glabrous outside. Corolla 8-8½ mm, tube 2 mm; midpetaline field 3.2- 4 by 1.6--1.9 mm, rather sparsely stellate-hirsute, in the lower part (l-2 mm) only along the margin (hairs (3- )4- 7(-8)-branched, branches subequal or, usually, one stronger and longer, up to 500 µ long); lobules 3.2-4 by 2- 2.5 mm, rather thin, with slightly distinct venation, entire. Stamens inserted 0.8-1 mm above the corolla-base; filament 1- 1.2 mm long, 0.4-0.5 mm broad at the base; anther 1- 1.3 mm long, 0.6-0.8 mm broad, 0.5 mm thick, acute to obtuse at the apex, slightly cordate at the base. Ovary ovoid, l. l- 1.7 by 1- 1.7 mm, glabrous; stigma conical, with 5 distinct and 5 rather low ridges.

Sepals transverse-oval, 1 & 2 2- 2.3 by 2.4-2.5 mm, 4 & 5 1.9-2 by 2.3 mm, densely stellate-hirsute outside (hairs with 4-7 subequal, up to 250 µ long branches). Corolla 6½ mm, tube 2 mm; midpetaline field 3½ by 2 mm, rather densely appressed-hairy (hairs 4-6-branched, branches subequal or one faintly longer and stronger, up to 550 µ long); lobules 2.5 by 2.7 mm, rather thin, with faintly distinct venation, faintly crenulated at margin, coherent above midpetaline field for 0.8 mm. Stamens inserted 0.6 mm above the corolla-base; filament 1.2 mm long, 0.4 mm broad at the base; anther 1 mm long, 0.5 mm broad, 0.4 mm thick, acute at the apex, faintly cordate at the base. Ovary 1.2 by 0.9 mm, glabrous for the lower 0.8 mm, stellate-hirsute for the upper part; stigma conical, with 10 distinct ridges.
