This plant was given me more than ten years ago by Mr. J. C. 
Bowring, who had formerly gathered it in Hongkong in company with 
the late Col. Champion. There is no allusion to it in the ‘Flora 
Hongkongensis. Though a good and complete specimen it has, like 
all Mr. Bowring's plants, been subjected to far too great pressure, so 
that it is only after the most careful maceration and boiling that I 
have succeeded in separating without injury the anthers from the 
stigma, and obtained a tolerably satisfactory view of the latter. I 
thought at first that this might be the Parsonsia? Helicandra of 
Hooker and Arnott; but, when the corolla is split open, the filaments 
are seen to be soldered with the tube, and to run up quite straight 
into the anthers. I suppose it is a true Parechites, though it does 
not dry of that peculiar pallid tint found in P. Thunbergii and many 
Asclepiadacee and Celastracee ; but the genera allied to Echites which 
have been founded by J. Mueller, Wight, and Miquel, having all been 
established from a comparison of the species of limited geographical 
areas, without a comprehensive study of all those known, will need a 
complete revision. As in Asteracee and Orchidaceae, there can be no 
doubt that the genera of Apocynacee and Asclepiadacee have been 
multiplied without reason ; slight variations in the form of orgaus, and 
the presence, absence, or various modifications of appendages of no ' 
structural importance whatever being the only grounds of distinction.
