The affinity of this is with B. globosa K. Schum., but among 

 other features its foliage is different, the corolla has but a very 

 short tube, and the coronal leaves are simple. It differs from 

 B. huhangensis in the narrower leaves, of which the uppermost 

 are alternate, the congested cymes, the colour of the flowers, the 

 shorter corolla-tube, the lanceolate scales on the corolla-lobes, the 

 short filaments not dilated at the base, and the smaller anthers.
