166 ILLUSTRATIONS OF INDIAN BOTANY. 



:it)ove (as In Perlploceae). Fruit follicular, follicles 2 or 1, by abortion ; placenta attached to 

 the flviture, separting in dehiscence. Seeds numerous, imbricated, pendulous, almost always 

 couujse at the hilum ; albumen wanting or thin ; embryo straight ; cotyledons foliaceous ; 

 radlule superior; plumule inconspicuous. — Twining or erect shrubs with milky juice, or her- 

 baceous, or very succulent perennials with watery juice. Leaves entire, opposite, rarely whorled ; 

 often furnished, at the insertion, with glands or hairs in lieu of stipules. Inflorescence extra 

 axillary, racemose, corymbose or more generally umbelled. Flowers presenting various shades 

 of red, yellow, or white, but rarely blue ; sometimes fragrant, occasionally, as In nearly the whole 

 tribe of Siapellea; exceedingly fetid like carrion.

INITIOS. Most Botanists coincide with Mr. Brown In viewing this order as very nearly 

 the preceding, the two principally differing in the peculiarities of their respective sexual 

 apparatus. Alphonse De CandoUe even goes so far as to affirm that the only constant difference 

 between them is to be found in the pollen. In this, as stated above (see Apocynacea?), I can 

 scarcely coincide, viewing, as I do, the presence of corpuscules In this family as a more certain 

 character, the pollen of Crypotolepis being about as distinctly granular as that of most Jpocy- 

 nacca. it forms no objection to this view that in the section Feriplocece the filaments are more 

 or less free and do not form a true gynostegium any more than in Jpocynacece, so long as they 

 all, in common with true Asclepiadece, have the stigmatic corpuscules, though In a modified form. 

 On these last, therefore, which are altogether wanting in Apocynncece, I lay greater stress than 

 on the pollen, and the two together will, I believe, never disappoint us in determining to which 

 of the two orders any doubtful plant should be referred. 



Lindley takes a very different view of the relationship these two orders bear to each other, 

 and places the one in his Gentianal the other in his Solanal alliance. He says, "It has already 

 been stated under the order of Dogbanes (Jpocynacece), that the resemblances found between 

 that order and the Asclepiads seemed to be one of analoi?y rather than of real affinity, for the 

 economy of the flowers and seeds of the two orders is widely "different. The amygdaloidal 

 embryo of Asclepiads, with hardly a trace of albumen is entirely different from that of 

 Dogbanes, which is very small and furnished with abundant albumen. The anthers and stigma 

 ot Dogbanes form no organic union, but they grow into one solid central mass in the Asclepiads,
