420 W. H. Harvey on two neiv Genera of Passiflo7'e(e. 



XLVI. — On two South African Genera of the Natural Order 



Passifloreae, with two Plates, from Drawings made by The 



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

 Since the publication of his very nseful ^ 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 ^Annals/ are the 

 Acharia tragoides, Thunberg, and Ceratiosicyos 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. 



Gen. Char. — Flores monoici. Masc. Perianthium tubuloso- 

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

 mina 6, triadelpha. Filamenta subulata, apice dilatata, et ibi anthe- 

 ras duas 2-loculures anticas ferentia. Foem. Perianthinm paullo 

 ultra medium trifidum, basi tribracteolatum, in fructu increscens. 

 Ovarium uniloculare, rostratum. Styli^ (potius 1, tripartitus) bifidi. 

 Stigmata fi, flabelliformia, membranacea. Capsula (brevi-pedicellata) 

 1-locularis, 3-valvis, 1- (vel rarius 2- aut 3-) sperma, valvis margine 

 (post dehiscentiam) involutis, rostro styloque acuminatis. Semen 

 ovoideum, arillo parvo unilateral! basi instructum. Embryo cylin- 

 dricus, in axi albuminis carnosi et dimidio brevior. Cotyledonus ra- 

 diculaque sequilongse. Am. Mst, 



Herba erecta gracilis. Folia alterna petiolata, exstipulata, pro-

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

 Thunberg's description alone, thought this genus might belong 

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