FLORA NIGRITIANA. 489 
Benin; Bahia in Brazil, where however it is probably 
introduced. 
In luxuriant specimens the stems are two to three feet high, 
the leaves as much as four inches long and three broad, and the 
flowers numerous. All that [ have seen are very badly dried, 
but as far as they go, I feel now convinced that the two species 
I had formerly distinguished were but forms of one, which 
varies in the number of flowers in the cymes, and in the lower 
lip of the calyx, entire or more or less toothed. I still, however, 
find no flowers in a state to decide whether it be really a 
Coleus or a Plectranthus.

Both the above species, as well as H. pectinata, Poit., and 
H. spicigera, Lam.,* are American plants which have spread 
into Tropical Africa and Asia: the only Hyplis hitherto indi- 
cated as exclusively African is the H. lanceefolia, Schum. et 
Thonn., from Guinea ; but that again may be a mere variety 
of the common H. brevipes. 
The Leonurus Sibiricus, Linn., and Leucas Martinicensis, 
Br, common Tropical plants, and both probably of Asiatic 
origin, notwithstanding the specific name of the latter, are also 
found in Senegal and Guinea. |

* I cannot subscribe to the statement in the Spicilegia Gorgonea, 
(supra, p. 157), that the floral leaves in this species are at first ovate and 
*htire, and afterwards divided into three or four linear partitions, which 
am said to have mistaken for bracts. The ovate and entire floral leaves 
are inserted on the main axis of the spike, and often fade and disappear 
as the spike advances in age. The linear bracts are inserted in the 
cymes themselves, at the basis of their branches, and may be seen at the 
Very earliest stage of inflorescence.
