Natural Order Cucurbitaceae. 269 



iri. each of the three cells of the ovary : nearly all Blume's spe- 

 cies belong to other genera. 



17. Citrullus (Schrad.). Corolla persistent, 5-parted, subrotate ; 

 anthers tri-adelphous, bilocular ; style trifid ; stigma obcordate, 

 convex ; fruit a fleshy or dry and fibrous, many- seeded pepo- 

 nida. Africa, East Indies — Cucurbita Citrullus and Cucumis co- 

 locynthis. 



18. Ecbaliam (Rich.). Corolla 5 - cleft ; anthers tri-adelphous; 

 ovules in 2 rows in each cell ; stigmas 3, 2-horned ; fruit an 

 elastically and irregularly bursting peponida. Europe — Momor- 

 dica Elaterium. 



19. Momordica (Linn.). Petals 5, adnate to the base of the calyx, 

 deciduous ; anthers all cohering ; ovules in a single row * in 

 each cell ; stigma 2-lo"bed ; fruit a capsular, elastically bursting, 

 3-valved peponida. East Indies, South Africa and America. 



To this genus seem to belong Muricia, Loureiro, and Neurosper- 

 mum, Raf. 



20. Luffa (Cav.). Petals 5, inserted in the base of the calyx, de- 

 ciduous ; anthers all distinct or di-tri-adelphous ; style 3-fid ; 

 stigma reniform or bipartite ; fruit a peponida, at length dry and 

 internally fibrous, usually opening by a terminal lid, rarely in- 

 dehiscent. East Indies and Arabia. There are three sections 

 of this genus. 



1st. Stamens distinct, Luffa pentandra, acutangula, and Kleinii. 

 2nd. Stamens 3-adelphous. L. amara, Roxb., and nearly all the 



species of Turia, Forsk. 

 3rd. Stamens di-adelphous — L. tuberosa, Roxb. 



21. Benincassa (Sav.). Corolla (yellow) 5-parted, patent; anthers 



3-adelphous ; style undivided, very short; stigma large, thick, 

 irregularly lobed and plaited; peponida fleshy, indehiscent. 

 Asia. 



22. Lagenaria (Ser.). Corolla (white) 5-petaled; anthers 3-adel- 

 phous ; style almost none ; stigmas 3, thick and 2-lobed ; pepo- 

 nida fleshy and indehiscent. India, South Africa. 



§ 8. Filaments 3-adelphous, inserted on the tube of the corolla ; 

 connectiva entire ; anthers 3- or mon-adelphous,posticous, linear, 

 bent upwards and downwards ; calyx long, tubular. 



23. Trichosanthes (Linn.). Segments of the corolla lacerated and 

 fringed ; anthers 3-adelphous ? or all united ; style trifid ; 

 stigmas oblong, subulate ; fruit a peponida, many-seeded. East 

 Indies. 



[In all the species I have had an opportunity of carefully examining, the 

 anthers are mon-adelphous or united. The style is not trifid, nor pro- 



* This, though practically correct, is not theoretically so, the carpellary 

 structure being the same here as in others ; each margin has its placenta and 

 ovules : and though at any one section only one row appears, we do not find 

 the ovules always attached to the same line of placenta on slicing the ovary 

 successively from end to end, but sometimes on the one, sometimes on the 

 other side of the cell ; such, at least, I find it in Momordica Charantia.
