The figure of Jacquin gives a very faithful representation of 
this plant, as well as good details of the structure of the flower. 
The fleshy immersed gland, about the size of a millet seed, seen 
near the axil of each nerve, offers a very characteristic mark of 
this species; its leaves are 4 inches long, inch broad, upon a 
petiole of 6 or 8 lines : the panicle is inches long. The whole 
plant, as in some other species of this genus, becomes black in 
drying.

— Manchester, Ins. Jamaicae ; v. s. in herb. Hook. (Purdie). 
This species is very similar to the foregoing one, but is di- 
stinguished by the want of the peculiar nerval gland and by the 
whole plant becoming less black in drying. Its leaves are 
inches long, li inch broad, on a petiole half an inch in length : 
the panicle is li to 2 inches long.
