A PLANT OF THE EDIBLE COLEUS, SHOWING THE POTATOLIKE 
TUBERS. 
(Coleus rotundifolius (Poir.) Cheval. and Perr., S. P. I. No. 51768.) 
This plant is cultivated in the Malay Peninsula, Ceylon, and in 
parts of Africa for its edible tubers. In Ceylon they are said 
to be regarded as superior in flavor to potatoes and fetch a 
higher price in the local markets. Chevalier notes three well- 
marked varieties under cultivation in Africa. (Photographed
