1914, in forests, altitude about 300 meters. Samar, Catubig River at 

 Pinipisakan, Bur. Sci. 2A266 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.

 obtusis vel obscure acuminatis, baud 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

 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 cm long. Fruiting spathe ovoid or oblong-ovoid, white, fleshy,
