56 Dr. Falconer on a reformed 



Since the above remarks were written (July last), I have learnt by letters 

 from Dr. Wight and Mr. Griffith, that both have been long aware of Crypto- 

 lepis being an Asclepiadea, Dr. Wight having ascertained the fact soon after 

 his return to India. 



Messrs. Wight and Arnott have arranged the mass of Wallich's Indian spe- 

 cies of Periploca under their new genus Streptocaulon, the distinction of which 

 is founded on the beardless anthers, and the flexuous direction of the aristse 

 of the scales. One of their species, S. calophyllum, is common in the Hima- 

 layas, and in it I find that the anthers are pointed and somewhat bearded ; it 

 has also shining leaves, and the follicles are parallel or divergent, not divari- 

 cate. A new species of the same group, from the neighbourhood of Cashmeer, 

 with a peculiar pseudo-aphylious habit, has the anthers decidedly bearded, and 

 the aristae of the throat-scales flexuose. The separation of either from Peri- 

 ploca seems hardly admissible ; and I suggest that & calophyllum be replaced 

 under Periploca, along with the Cashmeer species, of which the characters are 

 subjoined. Messrs. Wight and Arnott, the original constructors of Strepto- 

 caulon, had their doubts about its claims to rank as a distinct genus. 



1. Periploca calophylla. 



Volubilis glabra, foliis anguste lanceolatis longe attenuatis utrinque nitidis 

 transverse venosis, cymis subsessilibus paucifloris, floribus breviter pedi- 

 cellatis, corolla intus parce hirsuta, squamis hirsutissimis, folliculis elon- 

 gatis gracilibus subparallelis (nee divaricatis!).

2. Periploca Hydaspidis. 



Volubilis ramosissima glabra, ramis fasciculatis nodoso-articulatis, foliis tenu- 

 issimis hnearibus apiculatis adpressis remotis caducis, cymis axillaribus 

 mult,floris, floribus breviter pedicellatis, corolla intus squamisque tomen-
