140 AMES. 
B. Bolsteri 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 Krinzlin’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.

margo partis dimidiae basilaris erectus; pars dimidia superior, 
conduplicata, margine copiosi pilis instructis. Columna bipar- 
tita, laciniae bipartitae. 
Leaves, including the sulcate petiole, 21 to 30 cm long, 3.5 
to 5.5 cm wide. Petiole about 5 cm long. Scape 17 to 26 cm 
long. Bracts about 1 cm long, infundibuliform. Pedicel and 
ovary 2cm long. Flowers 1 or 2, mottled, yellow-red. Lateral 
sepals 4 cm long, 5 mm wide, conspicuously carinate, sulcate 
above, triquetrous. Upper sepal 3 cm long, about 1 ecm wide. 
Petals strongly refiexed, 1.5 cm long, 6 to 7 mm wide. Labellum 
1.4 em long, conduplicate for the most part, the basal portion 
cordate when spread out, with setiform, marginal teeth near 
the point of insertion, the margin’ otherwise, to about the middle 
of the lip, irregularly and shortly dentate. The lip, just beyond 
the middle is conduplicate, the upper margin long-papillose, 
papillae fleshy; on the under side it is longitudinally sulcate. 
Column about 1 cm long, divided at about the middle into two 
spreading lateral arms or wings, each wing deeply unequally 
cleft, the anterior division terminating in a setiform tip.
