Wallich Cat. 4256 consists of 3 sheets, all preserved at Kew. 4256a from Nepal, 4256b from Kumaon and 4256c from Silhet. There are no fruits on the first sheet. The fruits on the specimen from Kumaon are smaller than those from Silhet. M. Johnston (1969) regards 4256a as the probable holotype (ex Nepal). B. laxa Wallich Cat. 4257 (K) has larger fruits compared to 4256b or 4256c.
