 Wrai/ 1567 ; also on Gunong Batu Puleh, Wray 316. 



This resembles the Indian species B. Thomsonii, DC, bnt differs in being 

 caulescent, in having shorter hairs on leaves and petioles, and in the posterior 

 wing of the capsule being much larger. I have named the species after Sir Hugh 

 Low, late British resident at Malacca, to commemorate his many services towards 

 the botanical exploration of the Province of Perak.
