branous ; ovate, the apex acute or shortly acuminate, the base rounded,, 
slightly oblique ; both surfaces when dry brown, the upper quite 
glabrous, the lower paler, reticulate, sometimes with a few small hairs 
on the nerves ; main-nerves 4 or 5 pairs, curved, ascending, depressed 
like the midrib on the upper surface, prominent on the lower ; length 
2 to 3-5 in., breadth -75 to 1'75 in. ; petioles -3 to -4 in. Cymes ter- 
minal and lateral (extra- axillary), on long peduncles, dichotomously 
branched, sub-glabrous. Flowers - 3 to '4 in. long, sessile, forming 
crowded one-sided pseudo-spikes (scorpioid cymes) on the terminal 
inch or two of the branches of the cymes. Calyx about ‘05 in. long, 
only about a sixth or a seventh as long as the corolla, cleft nearly to the 
base into 4 broadly triangular acute spreading segments. Corolla-tube 
4-angled ; the limb short, with 4 ovate teeth, glabrous. Anthers 4, 
oblong, sessile or nearly so, near the throat. Fruit broadly ovoid, 
•15 to ‘2 in. long, with 4 vertical grooves (2 of them deep) on the sides, 
and a depression on the apex. Clarke in Hook. fil. FI. Br. Ind. IV. 147.

dichotomous cymes with scorpioid branches and small or no bracts, 
sometimes axillary in the axils of large bracts. Calyx divided into 
5 linear or lanceolate segments. Corolla with a cylindric tube and limb 
of various shapes, the lobes of the latter always imbricate or induplicate 
in bud, spreading in flower. Stamens 5, included, inserted on the tube 
by short filaments ; anthers ovate-oblong or lanceolate. Ovary com- 
pletely or imperfectly 4-celled, 4-ovulate ; style short or long, terminal, 
with a depressed conical or flat disk on its apex ; stigma above the disk,

or finally becoming so. Seeds straight or curved ; albumen none, small 
or large; cotyledons plano-convex.— Distrib. Species about 225, 
widely distributed in both hemispheres.
