SCHOMBURGK’S GUIANA PLANTS. 8I 
much detail in their description and comparison with allied 
species for insertion here. 
205. C. diphylla, Lam.—Vogel, Syn. n. 187.—Rocks of 
Aniparo on the Essequibo, and savannahs of the Upper 
Rupunoony. Schomburgk, n. 21. French Guiana, Leprieur, 
Herb. Mus. Par. n. 50. 
206. C. cultrifolia, Humb. et Kunth.— Vogel, Syn. n. 188.— 
Dry savannahs, British Guiana. Schomburgk, n. 401. 
207. C. uniflora, Spreng.—Vogel, Syn. n. 191.—Dry savan- 
nahs of the Rupunoony. Schomburgk. 
208. C. ramosa, Vogel, Syn. n. 195.—Savannahs of the 
Rupunoony. Schomburgk, n. 190. Also Pernambuco, Gard- 
ner, n. 988, and in Pohl’s, Mikan's, Salzmann's, Langsdorffs, 
and other Brazilian collections.— The petiolar gland is so very 
variable in the length and thickness of the stipes, that I am 
inclined to think this plant is but a variety of the S. uni- 
flora, in which the gland is entirely sessile.—Gardner's n. 
1574, from Ceará, is C. curvifolia, (Vogel.) 
I have many new Brazilian species of this section Xerocalyz, 
and some very distinct Chamecristz ; but the published species 
of these two groups are so numerous and often so much alike, 
_ that I do not venture to add any without detailed compara- 
. tive descriptions too long for the present paper. Gardner’s 
n. 26 from Rio Janeiro, and 967 from Pernambuco, are the 
C. rotundifolia, Pers., or C. bifoliolata, Collad., correctly 
referred to it by Vogel.— This, with the following species, 
and the other Chamuecriste with large stipules and fete: leaf- 
_ lets, form a little group, which with the habit = ee 
has the calyx of Chamecrista. :
