4. HOPPEA Willd. 



Small, much branched, glabrous herbs. Leaves small, sessile, ovate or 

 elliptic. Cymes 2-3-chotomous, flowers sessile or short-pedicelled. ' Calyx 

 campanula'te ; 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 1-celled, placentae 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. K. dichotoma, Wittd. in Ges. Nat. Fr. JBerl. Neue Schrift. iii. 435 ; 

 divaricately densely branched often from near the base, corolla ventricose shorter 

 than the calyx both in flower and fruit, lobes short triangular, capsule sub- 



tlobose. Hayne Termin. Bot. t. 30, Jig. 3. Hoppea dichotoma, Vahl Enum. i.

Throughout INDIA, 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. Calyx 

 p in.; lobes scarious, marginal nerve green. Corolla white, tube in., ventricose; 

 in fruit wider upwards with the lobes incurved, overtopped by the acute calyx-teeth. 

 Stigma clavate, obscurely 2-fid. 



2. II. fastig'iata, 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. 

 ix. 62. Pladera fastigiata, Amott in Herb. Wight ; Clarke in Journ. Linn.

S. DECCAN PENINSULA, Mysore and Courtallum, Wight ; Mangalore, Hohenacker. 

 MOULMEIN ; Lobb. CEYLON, frequent. 



Stem 2-6 in., winged. Leaves ^ in., ovate. Flowers fastigiate. Calyx in. ; 

 lobes scarious with a marginal nerve. Corolla-tube in. long, oblong, in fruit nar- 

 rowed in the tlwoat with the lobes erect, much overtopping the calyx-teeth. Stigma 

 sligfhtly 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 so 

 far agrees with Cicendia. 



5. ENICOSTSJS1A, Blume. 



A glabrous herb, erect, or decunilient 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, placentae not far intruded ; style short, linear, stigma capitate. 

 Capsule ellipsoid, carpels separating. Seeds many, subglobose, reticulated.
