CONSPECTUS OR ABRIDGED CHARACTERS OF THE GENE- 

 RA OF THE TRIBE CUCURBITEiE* OF SCHRADER. 



§ I. — Ffameiits 5, inserted on the throat of the corolla; anthers distinct 

 or Z-adelphous^ anficoits, straight ; fruit baccate^ few seeded. 



1 CoxiANDKA (Schrad.). Corolla 5-partite : conaectiva conniving, ob- 

 loDg, conical : fruit beaked. South Afinca. 



2 Cyrtoxema (Schrad.). Limb of corolla o-partite : filaments o, in- 

 curyed, counectiva incrassated 3-adelphous ; anihers fixed laterally under 

 the apex. South Africa. 



§ '2. —Filaments di or tri-adelphous^ inserted on the tube of the corolla ; 

 anthers lateral^ straiglit, 2-S-adelihous. 



3 SicYDiUM (Scblechr). Corolla 5-petaled, petals undivided : filaments 

 3-adelphous, dilated and incurved at the apex; anthers Viithout a beak. 

 Mexico. 



4 Bryoxopsis (Arn.). Corolla 5-partite, lobes obovate, entire, undulated: 

 filaments 3-adeiphous, inserted on the throat, straight ; anthers pointless : 

 stigma fringed : beiTy few seeded. Fast Indies — Courtal'um. 



5 AcHMA>-DEA (Arn.). Lubes of the corolla undivided : filaments 

 ti'i-adelphous very short ; anthers anticous, inserted along the marscins 

 of the connectivum, linear oblong: connectivura prolonged into a =^ ^rt 

 beak beyond the anther : fruit baccate (always ?) beaked. FaM 

 Indies. Bi^yonia epigaa^ rostrata, deltuidea, and an undescribed species 

 from Malabar. 



Obs. — Perhaps this and the tvro last genera 'might be joined to 

 Melothria. 



6 Melotheia (Linn.). Lobes of the corolla undivided, denticulated : 

 filaments 3-adelphous; connectivum pointless: fruit baccate, not beaked. 

 America. 



Obs. — Schrader notices an East Indian one, but that may perhaDs be 

 an Achmandra. 



7 Ceratosanthes (Schrad.). Lobes of the corolla linear bifid : filaments 

 3-adelphous. America. 



8 AsGURiA (Linn.). Lobes of the corolla entire : stamens diadelphous : 

 fruit somewhat 4-angled. America, 



§ Z.— Filaments B-adelphous inserted on the top of the tube^ anihers all 



• This tribe contains all the East Indian genera except Zt7;jw'cT — Schrader rf»fers Ery 

 ihropahivx of Blume to Cucurbitese but that genus is very closely allied to Mackai/a (Ar- 

 nott in Jardiue's Mag. of Zool. aad Bot. vol. 2) and does not belong to the order.
