B. Martiana ; labello ovali (aut ovato) acuminato ciliato-dentato sessili; petalis 
sepalisque lineari-lanceolatis acuminatis longioribus, clinandrio cucullato 
inciso. Bot. Reg. fol. 1914. in textu. 
Folia longa, teretia, suprà sulcis tribus exarata, racemo subcorymboso 
duplo longiora. Pedunculi leves, teretes, sepalis longiores, pone basin fusco- 
purpureo tincta. Sepala et petala lineari-lanceolata, subequalia, patula. 
Labellum ovatum aut ovale, acuminatum, fimbriatum, basi luteum ; ungue 
brevi columne appresso. -Columna apice cucullata, inflexa, fimbriata. 
This very distinct species of a small but interesting genus, 
imported from Berbice by Messrs. Loddiges, was originally 
discovered by Dr. Von Martius on the banks of the Rio 
Negro in Brazil, and it was from dried specimens in his her- 
barium that I first described it. 
B. cucullata and B. amazonica are the only other species 
yet known with a fringed labellum; the former has much 
larger flowers, and a lip of an entirely different form; the 
latter has a one-sided raceme, and a labellum contracted in 
the middle so as to be distinctly divided into a hypochilium 
and epichilium. 
All the Brasavolas yet described by Botanists now exist 
in this country, with the exception of B. subulifolia, a fine 
species inhabiting Nevis, with very slender subulate leaves, 
and the B. amazonica above named. The former might 
easily be procured; the latter is beyond the reach of ordi- 
nary travellers, occupying the branches of trees surrounding 
lake “ Egen,” one of the offsprings of the Amazons.
