An evergreen shrub. Leaves 4-6 by 14-2 in., rather membranous, dark brown 
when dry, finely aeuminate, base rounded or acute; nerves 12-14 pair, slender; 
uppermost pair often small and sessile; petiole 4—4 in.; stipules broad, cusp long. 
Cyme 4-2 in. diam.; branches short, pubescent, soon dividing and rather stout, 
puberulous ; bracts and bracteoles minute, subulate; flowers rather fascicled, white. 
Corolla very long (Kurz). Anthers sessile, base entire, Fruit unknown.—I have 
only two indifferent specimens from Dr. King and Helfer: both agree in all respeets 
with Kurz's description, except that the peduneles are not short, nor the corolla-lobes 
acute, and the flowers do not exceed 1 in. in length. The remarkable acumination of 
the leaves, and the cymes being hardly brachiate, distinguish it from all others of 
this group.

WESTERN PrNINSULA; on the Ghats from the Concan southwards. 
A tree 30 ft, ora stout shrub. Leaves 3-7 by 13-3 in., pale when dry, always 
obtuse, coriaceous or rather membranous, narrowed or rarely rounded at the base; 
nerves as faint as the veins; petiole 4-4 in, ; stipules short, cusps short. Cymes 4-6 
in. long and broad, rachis and long horizontal branches slender inarticulate, inter- 
nodes distant; lower bracts stipuliform, bracteoles minute; flowers white, odorous, 
sessile or pedicelled. Anzhers sessile. Style glabrous or pubescent; stigma sub- 
capitate, simple or cleft. Fruit globose or obscurely didymous, Seeds very thin, 
sides incurved so that the transverse section represents a dorsally compressed tube,— 
Flowers the smallest of the genus, and the only one with globose buds.
