hen describing the plants of this difficult genus for the ‘ Flora of 
British India,’ I regarded this and B. Gamblei as specifically different, 
but a re-examination of them for figuring in this work has led me 
to doubt their distinctness. The chief differences are, the longer 
petioled leaves Thomsoni, its fewer differently coloured flowers, 
and the absence of mucros the colum is possible, in 
S eed, 
that both may be referable to forms of Wight’s CO. nilgherrense 
(Ic. t. 1654), and all to C. acutiflorum, A. Rich. Living specimens or 
careful drawings can alone be relied on for specific characters of
