the secondary, about 10 on each side of the midrib, ascending ; 
petioles 9 to 13 cm long, the younger ones with membranaceous 
sheathlike margins up to 5 mm in width, extending nearly or 
quite to the apex of the petiole and there auriculate, these 
deciduous in age. Peduncles about 7 cm long. Spathes not seen. 
Spadices sessile, dense, cylindric, about 10 cm long, 1 cm in diam- 
eter. Filaments about 3 mm long, the anthers one-third as long. 
Pistil 4 mm long, somewhat angled by mutual pressure, about 
2 mm in diameter at the apex, slightly depressed, the stigma 
sessile, orbicular.

forests, altitude about 500 meters, flowers white. 
A species similar to and manifestly allied to Rhaphidophora perkinsiae 
Engl., from which it differs in its relatively narrower, somewhat thinner, 
slenderly acuminate leaves, its much slenderer spadices, and its shorter 
flowers.

CYANOTIS PEDUNCULATA sp. nov. § Eucyanotis. 
Planta circiter 20 cm alta, caulibus inferne prostratis, radican- 
tibus, parce ramosis; foliis oblongo-ovatis, chartaceis, glabris, 
acuminatis, usque ad 4.5 cm longis, in siccitate plus minusve pur-

circiter 5 mm longis, tubo 7 mm longo. 
A rather slender plant about 20 cm long, the stems prostrate 
below and rooting at the nodes, then erect or ascending, glabrous, 
simple or with a single branch. Leaves chartaceous, glabrous, 
oblong-ovate or oblong, 8 to 4.5 cm long, 1.5 to 2 cm wide, 
acuminate, base rounded, more or less purple when dry; sheaths 
loose, 6 to 8 mm long, bearded at the base and apex with long 
soft hairs, a few similar hairs along the side opposite the attach- 
ment of the leaf. Inflorescence terminal, the peduncles 5 to 6 cm 
long, the flowers rather numerous, scorpioid, but one or two 
opening at a time, all inclosed by two large, very unequal, im- 
bricate, spreading bracts, the basal parts of the bracts inflated, 
about 8 mm long, the larger one outermost and bearded in the 
central part of the inflated portion on both sides; limbs spreading, 
that of the smaller bract 1 cm long or less, of the larger one 
oblong, acuminate, up to 2.5 cm long. Flowers nuinerous, purple, 
scorpioid, but one or two opening at a time, the bracteoles nu-
