Plectranthus, one of the largest genera of Asiatic Ocimoidee, 
is distinguished from Ocimum by the concave lower division of 
its corolla, and from Coleus by the stamens not connected into 
a tube. It varies in habit and calyx, as well as in the form of 
the tube of the corolla, from which characters it has been di- 
vided into seven sections. To these ought perhaps to be added 
three more, Anisachilus, Mfollanthus and Pycnostachys, genera 
which have been founded merely upon peculiarities in the form 
of the calyx. The P. ternifolius, along with a closely allied 
South African species, forms the section Pyramidium; charac- 
terised by an erect, tubular or ovate, equally 5-toothed calyx (in 
the fruit-bearing state), a straight corolline tube, and a dense 
pytamidically paniculate inflorescence. Bentham.
