404 FLORA. NIGRITIANA. 
procumbens.—Cape Palmas, Vogel.—A small plant, with the 
habit of O. pumila, but with the capsules of O. herbacea and 
corymbosa. I have not been able to find any flowers. The 
species to which I have referred it is apparently a common 
one in Tropical countries. 
8. Oldenlandia corymbosa, Lam.—DC. Prod. 4. p. 426.—In 
various parts along the coast and on the Niger.—It is another 
of the common Tropical weeds. The lower part of the plant 
in the African specimen is sometimes hairy, and the stipules 
vary much in length. 
4. Oldenlandia /aziflora, Benth.; glaberrima, caule elongato, 
foliis subsessilibus oblongis lanceolatisve uninervibus flaccidis, 
pedunculis axillaribus elongatis apice laxe dichotomis, calycis 
fructiferi truncati dentibus 4 parvis remotis.—On the Nun 
River, Vogel. 
Caules flaccidi, pluripedales. Folia 2-8 poll. longa, 3-l poll. 
lata, tenuia, letevirentia. Stipule vaginantes, truncata, 
nude v. utrinque 1-2-sete. Pedunculi axillares, 4-2-polli- 
cares, apice dichotomi, ramis divaricatis, pedicellis ultimis 
3 lin. longis unifloris. Corollas non vidi. Calyces fructiferi 
14 lin. longi, paullo latiores, lateraliter compressi, apice tran- 
cati, dentibus parvis acutis. Capsula calyce paullo brevior, 
apice rima loculicida dehiscens. H 
- This appears to have some affinity with O. macrophylla and 
O. pentandra, but the former is described as having the pe 
duncles racemiferous, with opposite pedicels, and the latter 
as being pentamerous, on which account it may possibly be 
a species of Pentas, although the number of parts is not the 
character to be relied on for the distinction of the latter genus. 
Besides the four species above enumerated, seven species of 
Oldenlandia are described as West African, viz. : O. sabulost; 
DC., O. riparia, DC., O. linearis, DC., and O. macrophylla, 
Lepr. Perr., from Senegal; O. lancifolia, DC., O. longifolia, 
DC., and O. pentandra, DC., from Guinea; but these ann 
weeds vary so much in appearance, according to age, S350!» 
or station, that it is very probable a more careful investigation 
would much reduce the supposed number of species.
