Leaves 4-10 × 2-5.9 cm, broadly oblanceolate or obovate, apex rounded, truncate or emarginate, base acute to narrowly attenuate; glabrous above, short brown or reddish-brown tomentose below, indumentum persisting or falling to leave an underlying layer of closely appressed silvery or greyish hairs; midrib sunken on the upper surface; secondaries 12-15 pairs, often obscure, higher order venation areolate-reticulate, sometimes obscured; venation usually slightly impressed on the upper surface. Petiole 0.3-1.9 cm long, slightly channelled, tomentose to glabrous. Flowers 5-7 in a fascicle. Pedicel 1-1.5 cm long, shortly tomentose to sparsely puberulous, strongly reflexed in bud. Sepals 5-6 mm long, lanceolate, acute, shortly tomentose to sparsely appressed puberulous outside, appressed puberulous around the margin inside. Corolla glabrous, ca. 5 mm long, tube ca. 1 mm long; lobes six, divided to base into three segments, median segment narrowly boat-shaped, apex obtuse; lateral segments equalling the median segment, narrowly lanceolate, sometimes irregularly toothed. Stamens six, glabrous; filaments ca. 2.5 mm long, free; anthers ca. 1.5 mm long, lanceolate. Staminodes six, glabrous, 1.52 mm long, oblong, apex bilobed.

Distribution
NE Brazil (Bahía, Ceará, Paraíba, Pernambuco, Piauí, Sergipe) in subtropical forest and gallery forest on hills and mountains, around 700-1000 m altitude. Several specimens collected further south in the wet coastal lowland forest of Bahía (e.g., Froes 20047, Mori et al. 10305) are included in this species with some reservations.
