as constituting the closest known transition from that family to Apo- 

 cynece. He thinks the extreme minuteness of the appendiculae may 

 account for their having escaped Mr. Brown's observation in the dry 

 specimen ; but adds, that there are two other points of difference, 

 which lead him to suspect his plant to be distinct from that described 

 by Mr. Brown. These are the want of hypogynous scales, of which 

 he finds no trace, and which he believes to be wanting in the series of 

 Periploceous genera allied to Cryptolepis ; and the axillary, and not 

 interpetiolar, inflorescence. He also gives a detailed description of 

 the sexual organs, and states that he has never been able to observe 

 the pollen tubes either naturally or artificially produced. 



In a supplementary note, Dr. Falconer adds, that he has since 

 learned by letters from Dr. Wight and Mr. Griffith, that both those 

 gentlemen have been long aware of Cryptolepis being an Asclepiadeous 

 genus. With reference to Dr. Wight and Mr. Arnott's genus Stre- 

 ptocaulon, under which those authors include the mass of Dr. Wallich's 

 Indian species of Periploca, he observes, that S. calophyllum wants 

 the principal character on which the distinction of that genus from 

 Periploca is founded, and suggests its restoration to Periploca, of 

 which he also characterizes a new species from the neighbourhood 

 of Cashmeer with a peculiar pseudo-aphyllous habit. Of these spe- 

 cies he gives the following characters : — 



P. calophylla, volubilis glabra, foliis anguste lanceolatis longe attenuatis 

 utrinque nitidis transverse venosis, cymis subsessilibns paucifloris, flo- 

 ribus breviter pedicellatls, corollis intiis parce hirsutis, squamis hirsutis- 

 simis, folliculis elongatis gracilibus subparallelis (nee divaricatis !).

The following are the characters of this species, which Mr. West- 

 wood states to be most nearly allied to P. ruber, Thb., and of which 

 he has seen only a single specimen in the collection of Samuel
