420 W. II. Harvey on two new Genera of Passiflorece. 



XL VI. — On two South African Genera of the Natural Order 

 Passifloreae, ivith two Plates, from Drawings made by The 

 Hon. W. II. Harvey, of the Cape of Good Hope. 



Since the publication of his very useful i Genera of South 

 African Plants/ our valued friend Mr. Harvey has not ceased 

 to collect and draw and make notes upon new or rare species 

 of plants of that interesting country, and we have now before 

 us many excellent representations and remarks which he has 

 kindly communicated to us. Two of these, which appear 

 particularly deserving of a place in these f Annals/ are the 

 Acharia tragordes, Thunberg, and Ceratiosieyos Echlonii of 

 Nees von Esenbeck. 



1. Acharia tragoides, Th, 



(Plate IX.) 



We shall give the generic character of this in the words of 



Dr. Arnott, who has examined with great attention specimens 



lately sent to him, and which it will be seen differ remarkably 



from that of Thunberg.

 campanulatum, 3-lobam, basi bracteolis tribus parvis cinctum. Sta-

Hob. Uitenhage, Thunberg, Zeyher. 



Mr. Harvey, in his ' South African Flora 5 , judging from 

 Thunberg^s description alone, thought this genus might belong 

 to Euphorbiacea or Urticece; but now that he has received spe-
