The specific name here adopted for this species was published as a nomen 
nudum ,n 1880, and ^yith a description in 1883, being redescribed by Warburg 
in 1904 as B. glahrescens. Bomlycidcndron campylosiphnn (Turcz ) Warb is 
quite distinct from B. vidalianum, being characterized by its dense, soft pubes- 
cence, Vidal erroneously reducing the species, that was dedicated to him to 
Turczaninow's species. B. parvifolium Warb. is very similar to B. campylosi- 
phon m Its pubescence, but has smaller leaves. The type, preserved i„ the 
Berlin Herbarium, i.s very fragmentary, and consists of poorly prepared leaf- 
specimens only, so thnt it ^vill prove difllcult to establish the validity of the 
species. ■'
