Valleys below Simla ; April-August. — Nearly throughout India, ascending 
to 5000 ft. — Tropical Asia and Africa. 
In the FI. Br. Ind. this species is divided into nine varieties, of which the 
following two may be distinguished in Simla : — 
B. platyphylla proper. Leaves ovate, roughly wrinkled, tip pointed or 
narrowed in a short, tail-like point ; teeth small and uniform. 
Var. rotundifolia. Leaves orbicular, nearly smooth, tip abruptly narrowed 
into a tail-like point sometimes an inch long ; teeth large, often unequal. 
The Rhea and ‘ China grass 5 fibres are obtained from varieties of B. nivea , 
a native of China and the Malay islands, believed to have been introduced into 
India in very early times. The cultivation of this plant, and the extraction of 
the fibre, have formed the subject of numerous experiments during recent 
years, but up to the present time without marked commercial success.
