1914, in forests, altitude about 300 meters. Samar, Catubig River at 
Pinipisakan, Bur. Sci. 24266 Ramos, March 21, 1916, in forests along the 
river. Mindanao, Agusan Subprovince, Amparo, For. Bur. 7615 Hutchin- 
son, August 23, 1907, in open forests, altitude about 30 meters. It is known 
in Leyte as biga, the common name for Alocasia macrorrhiza Schott, and 
in Samar as handuroy. 
A remarkable species belonging in the same group with Alocasia 
macrorrhiza Schott, to which, however, it is not closely allied. It is well 
characterized by its large, oblong-ovate, coriaceous, very smooth, shining 
leaves, the basal lobes deflexed, not at all spreading, often attaining a 
length of one-half the lamina, and its very obscure reticulations.

Planta robusta, pedunculis et subtus foliis furfuraceo-hispid- 
ulis; foliis late ovatis, usque ad 90 cm longis et 50 cm latis, 
obtusis vel obscure acuminatis, haud peltatis, lobis latissime ova- 
tis, rotundatis, comparate brevibus, nervis utrinque circiter 10 
utrinque, subtus valde prominentibus, patulis, curvatis, basilari- 
bus utrinque pinnati-nervosis, leviter deflexis, usque ad apicem 
loborum attingentibus, reticulis prominentibus; inflorescentiis 
numerosis, pedunculis usque ad 30 cm longis; spathis circiter 10 
cm longis, tubo sub fructu accrescentibus, albis, carnosis, oblongo- 
ovoideis, usque ad 8 cm longis; spadicis 8 ad 10 cm longis. 
A robust plant, the caudices in old specimens stout, attaining 
a height of about 0.3 m, perhaps higher. Leaves membrana- 
ceous, broadly ovate, up to 90 cm long and 50 cm wide, entire, 
apex obtuse to obscurely acuminate, base not at all peltate, with 
two very broad, rounded lobes which are at most 20 cm long, and 
as wide or wider than long, the sinus rather broad, somewhat 
rounded, the upper surface, when dry, minutely puncticulate- 
verruculose, the lower uniformly and distinctly furfuraceous- 
hispidulous on the nerves and reticulations ; lateral nerves about 
10 on each side of the midrib, prominent on the lower surface, 
spreading, curved, the basal pair somewhat deflexed and reaching 
the tip of the lobes, bearing from 3 to 5 pinnately arranged 
secondary nerves on each side; petioles stout, up to 1.5 m in 
length, rather densely furfuraceous-pubescent. Inflorescences 
numerous, up to 30 on each plant, their peduncles pubescent, 
up to 30 cm in length. Spathes about 10 cm long, the tubular 
portion 1 to 1.5 cm long, the limb lanceolate or oblong-lanceolate, 
membranaceous, about 6 cm long, acuminate. Pistillate portion 
of the spadix about 1 cm long, the flowers crowded; style short, 
distinct ; stigma obscurely lobed. Staminate portion of the 
spadix about 2 cm long, cylindric, the sterile appendage about 
5 cni long. • Fruiting spathe ovoid or oblong-ovoid, white, fleshy,
