Terrestrial or lithophytic caulescent herb to 50 cm tall, not branching. Stems fleshy, 
eglandular hairy, green or purple-brown, with white and patent hairs, internodes to 
c. 13 cm. Leaves opposite, except for the single basal cotyledon; petioles 2-10 cm 
long, eglandular hairy; blades pale to dark green above with hispid eglandular hairs, 
pale green beneath, with the same type of indumentum, elliptic, ovate or lanceolate, 
4.2-14.5 x 1.8-7.5 cm, 1.5-2.7 times as long as wide, base acute to obtuse or almost 
cordate, often unequal, apex acute to acuminate, margin entire to serrate, 7-16 pairs of 
secondary veins, venation slightly sunken above and raised beneath in fresh material, 
tertiary venation often inconspicuous. Leaves and bracts mid green above, whitish 
green beneath. Inflorescences arising from the petiole, at the axil or in close proximity, 
consisting of one to three main pedunculate inflorescences, each very compressed and 
thus appearing subumbellate and bearing 1-10 flowers; peduncle 2-140 mm long, 
eglandular hairy; bracts sessile, partly or completely fused in a cup, 5-50 mm long, 
with patent white eglandular hairs on both sides, palmate venation, margin serrate 
and when partly fused, with acute apex; pedicels green, 0.1-15 mm long, eglandular 
pubescent. Calyx yellow-green, bilabiate with the lower lobes shorter than the upper, 
tube 0.3-0.5 mm long, lobes narrowly lanceolate to triangular, 7-8 x 1.1-1.2 mm, apex 
narrowly acute, eglandular hairy on the outer side, sometimes only at the tip and along 
the margin, inside glabrous. Corolla 16.5-22 mm long, with tube white and lobes 
white to violet, with thin dark stripes and a yellow marking ventrally in the throat, 
tube narrow at base (5.5-6 mm), then abruptly opening into spreading lobes, tube 
glabrous, limb densely eglandular hairy outside, internally with dense glandular hairs 
in the throat, especially on the upper lip and on the ventral lobe, further in with shorter 
glandular hairs; tube c. 13-13.5 mm long dorsally, 12-16.5 mm ventrally, 11.5-13.5 
cm laterally between lips; upper lobes broadly elliptic, 4.5-5.5 x 4.5-6 mm, lateral 
lobes elliptic, 4-5.5 x 5-6 mm, lower lobe elliptic, 4.5-6.5 x 5.5-7 mm. Stamens 
arising 6-9 mm above the corolla base, slightly bent, glabrous, 3.5-4 mm long, 0.4- 
0.5 mm wide; anthers pale yellow, hairy dorsally and partially beneath, 2-2.1 x 1-1.3 
mm, free, thecae divergent; lateral staminodes 0.7-2.5 mm long, arising 5.5-7.5 mm 
above the corolla base, glabrous, central staminode 0.2-0.7 mm long, arising 6-8 
mm above the corolla base. Disk a partial ring interrupted dorsally, lobed, 0.3-0.5 
mm. Pistil 13.5-16.5 mm long; ovary 7.5-11 mm long, glabrous for 2-3 mm at base, 
otherwise densely eglandular hairy; style white, 4.5 mm, more sparsely hairy than the 
ovary; stigma white, elongated and flexed downwards, eglandular hairy, lobes 1.5-1.8 
x 0.4-0.5 mm, elliptic. Fruit green, 1.1-4 cm long, c. 1.5 mm diameter, glabrous at the 
base, otherwise sparsely eglandular hairy, straight or slightly curved. Seeds not seen.
