Flowers subsessile to shortly pedicellate. Calyx glabrous; hypanthium portion turbinate, ca. 1 mm; limb 2-3 mm, deeply lobed; lobes linear-lanceolate to narrowly ligulate. Corolla white, glabrous outside; tube ca. 4 mm, white villous in throat; lobes oblong-triangular, 1.5-2 mm, apex incurved.

In the protologue the stipules were incorrectly described as "apice longe acuminatis." In fact, it is the individual lobes that are long acuminate, while the stipules are deeply bilobed.
