1} in., ovate-lanceolate, crenate-toothed, somewhat pubescent, petiole 
1-2 in. long. Cymes axillary, lax, few-flowered. Calyx j in. long, 
divided nearly to the base, glandular-hairy. Corolla-tube 2} in. long, 
upper half gradually swollen, curved ; lobes 3 in. long, nearly actino- 
morphic, subquadrate, obliquely erect, deep mauve. _ Anthers and 
pollen of genus. Capsule % in. long, cylindric, perfecting 8-12 seeds 
from the base; seeds discoid, glabrous on the faces, with hygroscopic 
hairs on the margin.— Heteradelphia Paulowilhelmia, Lindau in Engl.

This plant is made by Lindau the type of a new genus separate from Paulo- 
wilhelmia by the approximation of the two membranes whence the lateral pairs of 
stamens spring. The difference in the shape of the corolla would be a stronger reason 
for separating it generically ; but the enormous differences in size and shape of the 
corolla in allied genera (as in Ruellia) do not dispose to attributing much weight even 
to that character.

Calyx divided nearly to the base; segments 5, linear or narrow- 
ligulate, subsimilar, 2 anticous often rather shorter, posticous rather 
broader. Corolla about 1 in. long; tube inflated nearly from the base; 
lobes 5, subequal, ovate, contorted in bud, nearly actinomorphic. 
Stamens 4, subsimilar; filaments nearly glabrous; anthers of two 
anticous stamens with one cell long-spurred ; pollen short-ellipsoid, 
somewhat trigonous, ribbed lengthwise. Style hairy below, with one 
linear-oblong branch, the other very short or 0; ovary with 6 or more 
ovules. Capsule lanceolate seed-bearing from the base, usually per- 
fecting 6 or 8 seeds. Seeds nearly glabrous on faces; margin with 
very many hygroscopic hairs.—Shrubs. Leaves long-petioled, ovate, 
irregularly (often coarsely) toothed. Inflorescence a quasi-terminal 
panicle, lax or dense; bract usually remote from the calyx ; bracteoles 2, 
linear or ligulate, persistent, shorter than the calyx. 
Species 10-12, endemic in Tropical Africa and Mascarenia, 
Differs from Paulowilhelmia by having 2 anther-cells very strongly spurred, the 
other 6 muticous or obscurely pointed. 
Cymes open, many pedicels up to 4 in. long.
