The genus Plectranthus, according to the Index Kewensis contains about 70 

 species found in tropical and sub-tropical regions. In Natal we have many species 

 some of which are as yet undescribed, and probably P. saccatus is one of the hand- 

 somest of them. It is usually found in damp places in shade, and is frequently 

 seen in cultivation.
