52 Bemarks on the fruit of the Natural Order Cucurhitace<s. [July 



§ 8. — Filaments, S-adelphovs, inserted on the tube of the corolla ; cori' 

 nectiva entire^ anthers S-or mon-adelphuiis, posticous^ linear^ hent upwards 

 and doumwards : calyx long, tubular, 



23 TnrcHosANTHEs (Linn.). Segments of the corolla lacerated and fring- 

 ed : anthers 3-adelphous ? or all united : style trifid ; stigmas oblong, 

 subulate : fruit a peponida, many seeded. E. Indies. 



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

 the anthers are monadelphous or united. The style is not trifid, nor 

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

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

 distance < utwardly, and presents a somewhat subulate outline.] 



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

 bracteas, the character taken from the anther not holding good, at least 

 T. Cucumerina has frequently the anthers all united, and I suspect also 

 jT. Anguina ; perhaps they only become tri-adelphous 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. 

 globosa, and trifoliata^ Blume, 2iud Involucrarea, Serange (T. Wal/ichana) 

 form a very characteristic section, perhaps a subgenus, distinguished 

 by their curiously bracteated male flowers]. R. W. 



24 Gymnopetalum (Am.). Calyx constricted at the mouth : corolla 

 (yellow) 5 parted ; segments quite entire : anthers all closely cohering : 

 fruit baccate, ovate, beaked, few seeded : seeds large, roundish, with a 

 blunt margin E. Indies. There are two species— 



1 G. Ceylanicum (Arn.). Leaves deeply 5 lobed ; perianth glabrous : 

 Bryonia tubiflora. W. and A. 



2 G. Wightii (Arn.). Leaves 3-5-angle-lobed ; perianth hairy. CourtaU 

 lum. 



§ 9i — Filaments usually tri-adelphous, inserted at the lase of the peri- 

 anth ; connectiva entire, unless when produced into appendages beyond the 

 anthers ; anthers linear, posticous, bent upwards and downwards (calyx 

 campanulate or rarely infundibuliform.) 



25 CucuMis (Linn.). Corolla 5-parted : anthers tri-adelphous, or all of 

 them slightly cohering, with appendages at the apex ! Peponida fleshy, 

 indehi scent, or rarely irregularly dehiscent, polyspermous : seeds ovate, 

 compressed, sharp edged. Asia, Africa and America. 



26 Cue ORBIT A (Linn.). Corolla campanulate, 5-cleft: filaments tria- 

 delphous at the base or quite monadelphous; anthers all cohering, 

 without appendages : peponida fleshy, indchiscent, polyspermous : seed 

 •with a slightly thickened edge. Asia and America*
