B. Bolateri and B. chryseum (Kranzl.) Ames are very near allies, 
differing mainly in the more rambling habit of B. Bolsteri and in the 
proportions of the flowers, B. Bolsteri being a larger flowered species 
with smooth petals, the median nerve unbranched. Unfortunately, I have 
not seen the type of B. chryseum, but among the Philippine plants in 
my herbarium there is one collected by W. S. Lyon 152, which answers 
so closely to Kranzlin’s description in Fedde’s “Repertorium” that I feel 
sure it must be that species. 
B. Bolsteri is suffused with purple in dried specimens, conspicuously so 
at the base, while B. chryseum is light-yellow.
