The elongated scapes, which are about twice as long as the 

 leaves, with the flowers 6-7 mm. apart in slender racemes, give

 closely allied to B. Escritorii of all known Philippine species. 

 B. Vanoverberghii has much broader leaves and is easily distin- 

 guishable by means of its different inflorescence. The elongated 

 scapes of B. Escritorii and the less acuminate lateral sepals
