5, Sida stipulata, Cav. diss. 1. p. 22. t. 28. f. 10.—S. prostrata, 
G. Don, Gard. Dict. 1. p. 490.—Sierra Leone, Vogel, 
Don. 
These specimens have slender ariste to the carpels. The 
species is a native of both the East and West Indies, and is con- 
sidered by Dr. Planchon as a mere variety of S. acuta. 
6. Sida refusa, Linn.—St. Thomas, Don. 
The leaves of these specimens are either obtuse or acute, and 
scarcely retuse, as is frequently the case with East Indian speci- 
mens, where it occurs as far east as the Phillippine Islands. 
The carpels terminate in a subulate point. Dr. Planchon con- 
siders it a mere variety of S. rhombifolia. 
7. Sida acuta, Burm., Cav. diss. 1. p. 15. t. 2. f. 8.—S. ovata, 
G. Don, Gard. Dict. 1. p. 492.—Cape Coast, Vogel ; St. 
Thomas, Don. 
Certainly identical with the East Indian species of this name. 
Don’s specimens have luxuriant foliage. 
8. Sida Vogelii, Hook. fil.; gracilis, erecta, glaberrima, caule 
virgatim ramoso, foliis petiolatis lineari-lanceolatis acutis 
ineequaliter subacute serratis basi rotundatis, stipulis glaber- 
rimis petiolum superantibus, pedunculis axillaribus solitariis 
(rarius binis) unifloris gracilibus medio articulatis petiolis ter 
longioribus, calyce glaberrimo segmentis acuminatis, carpellis 
subsenis 2-rostratis.—Fernando Po, Vogel. 
Suffrutex 2-3-pedalis, ramosus. Caulis crassitie pennæ cor- 
Vine. Stipule majuscule, petiolum gracilem + unc. longum 
superantes. Folia utrinque glaberrima, 1}-2 unc. longa, 
4-5 lin. lata, submembranacea. Pedunculi graciles, erecti. 
Carpella dorso rugosa, rostris paulo divaricatis. 
I believe this to be a very distinct species, more similar to the 
N. American S. Elliottii than to any other. lt differs from 
S. spinosa and allits varieties in wanting the spine, and in the 
long peduncles; from S. stipulata, (which it otherwise much 
resembles), in the stipules ; from S. acuta, by the same el 
ters, and from S. rhombifolia in the smooth leaves, which are 
not hoary. 
There are four other W. African Side, all from Senegal;
