perly speaking the stigmas subulate, as they cohere nearly to the apex 

 by their central face, though the stigmatic surface extends for some di- 

 stance outwardly, and presents a somewhat subulate outline.] 

 I reunite Involucrarea to this as a mere section depending on tlie 

 bracteas, the character talcen from the anther not holding good, 

 at least T. cucnmerina has frequently the anthers all united, and 

 I suspect also T. anguina ; perhaps they only become tri-adel- 

 phous after fecundating. 

 [In T. anguina they are never tri-adelphous, the anthers cohere to the 

 last as represented in the accompanying figure. This last species, with 

 T. glohosa and trifoUatu, Blumc, and Involucrarea, Serange ('/'. Wal- 

 lichana), form a very characteristic section, perhaps a subgenus, distin- 

 guished b}' their curiously bracteated male flowers. — R. W.] 



24. Gymnopetalum (Am.). Calyx constricted at the mouth; co- 

 rolla (yellow) 5 -parted; segments quite entire; anthers all 

 closely cohering ; fruit baccate, ovate, beaked, few-seeded ; 

 seeds large, roundish, with a blunt margin. East Indies. There 

 are two species : — 



1. G. Ceylanicum (Am.). Leaves deeply 5-lobed ; perianth gla- 

 brous. Bryonia tvbiflora. W. and A. 



2. G. Wightii (Am.). Leaves 3 — 5, angle-lohed ; perianth hairy. 

 Courtallum. 



§ 9. Filaments usually tri-adelphous, inserted at the base of the 

 perianth ; connectiva entire, unless when produced into append- 

 ages beyond the anthers ; anthers linear, posticous, bent up- 

 wards and downwards {calyx campanulate or rarely infundibu- 

 liforni) . 



25. CucuMis (Linn.). Corolla 5-parted ; anthers tri-adelphous, or 

 all of them slightly cohering, with appendages at the apex I 

 Peponida fleshy, indehiscent, or rarely irregularly dehiscent, po- 

 lyspermous ; seeds ovate, compressed, sharp-edged. Asia, 

 Africa and America. 



26. CucuRBiTA (Linn.). Corolla campanulate, 5 - cleft ; filaments 

 tri-adelphous at the base, or quite mon-adelphous ; anthers all 

 cohering, without ajipendages ; peponida fleshy, indehiscent, 

 polyspermous ; seed with a slightly thickened edge. Asia and 

 America. 



27. Elaterium (Linn.). Petals scarcely united at the base ; fila- 



ments mon-adelphous ; anthers all cohering ; style thick ; stigma 

 capitate ; fruit a coriaceous, 1 -celled, few-seeded capsule, burst- 

 ing elastically by two or three valves. America. 



28. ScHizocAHPEUM (Sclilch.). Corolla infundibuliform, quite en- 

 tire ; filaments 3-adelphous ; anthers all cohering; peponida 

 many-seeded, bursting by several valves that cohere by their 

 apex. Mexico. 



29. CocciNiA (W. and A.). Corolla campanulate ; segments acu- 

 minated; filaments mon-adelphous; anthers tri-adelplious, conni- 

 ving, without appendages ; peponida somewhat baccate, many- 

 seeded. [Usually of an oblong oval shape, and bright red when 

 ripe.] East Indies.
