[* This though practically correct IS not theoretically 

 60, 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 iu Momordica Charaniia.'] 



To this genus seems to belong, Muncia^ Loureiro and 

 Neurospermum^ Raf, 



20. LiiFFA (Cav.) Petals 5, inserted in the base of 



the calyx, deciduous : anthers all distinct or di-triadel* 



phous : style 3 fid ; stigma reniform or bipartite : fruit a 



peponida, at length dry and internally fibrous, usually 



opening by a terminal lid, rarely indehiscent. East In^ 



dies and Arabia. There are 3 sections of this genus.

 anthers 3-adelphous : style almost none ; stigmas 3, thick 

 and 2-lobed : peponida fleshy and indehiscent. Jndiay

I reunite Jnvolucrarea to, this as a mere section de- 

 pending on tlie bracteas, the character taken from the 

 anther not holding good, at least T. Cucumerina has fre- 

 quently the anthers all united, and I suspect also T. an- 



guina; perhaps they only become tri-adelphous after 

 fecundating. 



[In all the species I have had an opportunity of care- 

 fully 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 cen- 

 tral face, though the stigmatic surface extends for some 



distance outwardly, and presents a somewhat tubulate 



outline. 



In T. anguina they Hte never tri-adelphous, the an- 

 thers cohere to the last as represented in the accompany- 

 ing figure. This last species with T. globosa, and fn- 

 yo/m/a, Blume, and Jnvolucrarea, Serange (7\ Wallich^ 

 ana) form a very characteristic section, perhaps a sub- 

 genus, distinguished by their curioubly bracteatcd male 

 flowers]. R. W.

 mouth ; corolla (yellow) 5-parted ; segments quite en-

 margin E, Indies. There are two species

EXPLANATION OF PLATE 103. 



ZaNOSIA IND2CA. 



1. Flowering branch (male plant) natural .size, 



2. Male flower, the petals removed, showing the 3- 

 lobed calyx and inserlion of the anthers. 



3. An expanded fljwer showing the petals and stamens. 

 4- Corolla and calyx detach- d, the stamens more hig-h • 



ly magni/ied, to show the form of the anther. 



5. A fruit cut transversely. 



6. A seed. 



For this figure and dissection the draftsman is wholely 

 responsible. It was executed while I was in EnglamL 

 and I have had no opportunity of comparing it with liv^ 

 ing plants to aHcertaiii its accuracy, 1 suspect however 



there is an error iu making it a moncecious plant.
