O. dispar, V.E. Br. in Kew Bulletin, ined. 
The genus Ovxalis, of which upwards of four hundred 
and fifty species are known, is largely represented in Brazil 
and Guiana, from which countries more than one hundred 
species are described by Prognel in the second volume of 
Martius’ “ Flora Brasiliensis.” Amongst the latter, the 
nearest (and very near) ally of O. dispar is O. Laureole, 
Progn., which has shorter petioles and leaflets, much 
smaller, more racemose flowers, and filiform, pilose styles. 
Another near ally is O. Noronhe, Oliv. (in Hook. Ic. PI. 
t. 1226), a native of Fernando de Noronha, a small group 
of oceanic islands which lie two hundred and ten miles 
N.-E. of Cape St. Roque, the easternmost point of Brazil. 
A description of this group, the largest island of which is 
a penal settlement, is to be found in the “ Naturalists’ 
Voyage” of Mr. Darwin, who was, I believe, the first man 
of science that ever landed on it, and make a collection 
of its plants. O. Noronhex differs from O. dispar in its 
shorter, broader leaflets, small flowers, slender styles, and 
glabrous filaments. 
0. dispar was obtained for the Royal Gardens, Kew, 
from Messrs. F. Sander & Co., of St. Albans. It flowered
