CONSPECTUS, OR ABRIDGED CHARACTERS OF THE GE- 

 NERA OF THE TRIBE CUCURBITEtE * OF SCHRADER. 



§ 1. Filaments 5, inserted on the throat of the corolla ; anthers 

 distinct or 3-adelphous, anticous, straight ; fruit baccate, few- 

 seeded. 



1. CoNiANDRA (Schrad.). Corolla 5 -partite ; connectiva conniving, 



oblong, conical ; fruit beaked. South Africa. 



2. Cyrtonema (Schrad.). Limb of coroUa 5 -partite ; filaments 5, 



incurved; connectiva incrassated, 3-adelphous ; anthers fixed 

 laterally under the apex. South Africa. 



§ 2. Filaments di- or tri-adelphous, inserted on the tube of the 

 corolla ; anthers lateral, straight, 2 — 3-adelphous. 



3. SiCYDiUM (Schlecht). Corolla 5-petaled, petals undivided; fila- 



ments 3-adelphous, dilated and incurved at the apex ; anthers 

 without a beak. Mexico. 



4. Bryonopsis (Am.). Corolla 5 -partite ; lobes obovate, entire, un- 



dulated ; filaments 3-adelphous, inserted on tlie throat, straight ; 

 anthers pointless ; stigma fringed ; berry few-seeded. Fast 

 Indies — Courtallum . 



5. AcHMANDRA (Am.). Lobes of the corolla undivided ; filaments 



tri-adelphous, very short ; anthers anticous, inserted along the 

 margins of the connectivum, linear, oblong ; connectivum pro- 

 longed into a short beak beyond the anther ; fruit baccate (al- 

 ways ?) beaked. Fast Indies. Bryonia epigcea, rostrata, del- 

 toidea, and an undescribed species from Malabar. 

 Obs. Perhaps this and the two last genera might be joined to 

 Melothria. 



6. Melothria (Linn.). Lobes of the coroUa undivided, denticu- 



lated ; filaments 3-adelphous ; connectivum pointless ; fruit bac- 

 cate, not beaked. America. 

 Obs. Schrader notices an East Indian one, but that may perhaps 

 be an Achmandra. 



7. Ceratosanthes (Schrad.). Lobes of the corolla linear, bifid ; 



filaments 3-adelphous. America. 



8. Anguria (Linn.). Lobes of the corolla entire; stamens di-adel- 



phous ; fruit somewhat 4-angled. America. 



§ 3. Filaments 3-adelphous, inserted on the top of the tube; anthers 

 all cohering by means of their connectiva, and applied at the 

 back along the margins of the connectiva, sigmoid. 2-celled. Q) 



9. Schizostigma (Am.). Style simple; stigma peltate, fleshy, cleft 



* This tribe contains all the East Indian genera except Zanonia. 

 Schrader refers Erythropalum of Blumo to Cucurhitcce, but that genus is 

 very closely allied to Mackaya (Arnott in Jardinc's Mag. of Zool. and Bot., 

 vol.ii.), and docs not belong to the order.
