Note
The Kew specimen of Gilbert 5377 is a complicated mixture and the original determination B. densa is correct for most of the material, which has papillate nutlets. I had hoped that the original material at EA would provide further material of the new species but both sheets are entirely of B. densa. The new taxon is perhaps close to B. leiolepis but that has a persistent style base.
