pair are hirsute; the anthers though muticous as in P. verticillata are 
contiguous and not discrete. The fruit is unknown. 
As both these species belong to one natural group it may be useful 
to provide a key, modified, so as to admit of their reception, froih the 
key already published by the writer (Ann. Roy. Bot Garden., Calcutta, 
94)j in which the relative position of these and of the previously- 
known species is shown.
