elliptic. Cymes 2-3-chotomous, flowers sessile or short-pedicelled. Calyx 
campanulate ; lobes 4, ovate, acuminate. Corolla-tube subglobose or elongate ; 
lobes 4, short or long, more or less unequal. Stamens 1 perfect, 3 barren, 
attached in the corolla-throat, filaments linear short ; anthers ovate, dehiscing 
introrsely by two longitudinal slits; barren anthers similar but much smaller, 
sometimes 0. Ovary l-celled, placentze not far intruded ; style short, stigma 
subentire. Capsule globose or ellipsoid, carpels separating. Seeds very many, 
minute, nearly black, obscurely reticulated.—Species 2, Indian. 
1. H. dichotoma, Willd. in Ges. Nat. Fr. Berl. Neue Schrift. iii. 495; 
divaricately densely branched often from near the base, corolla ventricose shorter 
than the calyx both in flower and fruit, lobes short triangular, capsule sub- 
globose. Hayne Termin. Bot. t. 30, fig. 3. Hoppea dichotoma, Vahl Enum. 1.

Throughout Inp1, alt, 0-3000 ft.; very common; from the Punjab and Assam 
to Belgaum and Central India, the Circars, and Chittagong. 
Stem 1-5 in. quadrangular. Leaves in. ovate. Cymes dense or lax. Caly? 
Š in.; lobes scarious, marginal nerve green. Corolla white, tube Jj; in., ventricose; 
in fruit wider upwards with the lobes incurved, overtopped by the acute calyx-teeth. 
Stigma clavate, obscurely 2-fid. 
2. H. fastigiata, Clarke; corymbose upwards with ascending branches, 
corolla tubular lobes oblong overtopping the calyx both in flower and fruit, 
capsule ellipsoid. Cicendia fastigiata, Griseb, Gentian. 158, and in DC. Prodr.

Stem 2-6 in., winged. Leaves } in., ovate. Flowers fastigiate. Calyx din; 
lobes searious with a marginal nerve. Corolla-tube 3, in. long, oblong, in fruit nat 
rowed in the throat with the lobes erect, much overtopping the calyx-teeth. „Stigma 
slightly clavate, subentire. Seeds very small, but twice as large as those of H. dicho- 
toma.—The type of Cicendia fastigiata, Griseb. is Macrae’s Ceylon plant, which 
Grisebach (Gentian. 159) says has 4 perfect stamens, but it has 1 only. The corolla 
in the present species is totally unlike that of Hoppea dichotoma, and the species 8? 
far agrees with Cicendia. 
5. ENICOSTEMA, Blume. 
A glabrous herb, erect, or decumbent branched. Leaves sessile, ovate- 
lanceolate or linear. Flowers small, in sessile axillary clusters. Calyx deeply 
5-fid; segments not keeled. Corolla tubular funnel-shaped ; lobes 5, spreading; 
white or bluish. Stamens 5, on the upper part of the corolla-tube, filaments 
shortly linear with minute scales at their base ; anthers oblong, acute, included. 
Ovary 1-celled, Piacente not far intruded ; style short, linear, stigma capitate. 
Capsule ellipsoid, carpels separating. Seeds many, subglobose, reticulated.
