ALOCASIA WENZELI! sp. nov. § Eualocasia. 
Planta magna, glabra; foliis longe petiolatis, usque ad 1 m 
longis, haud peltatis, oblongo-ovatis vel ovatis, coriaceis, nitidis, 
laevis, margine cartilagineis, sursum angustatis, apice obtusis ad 
leviter acuminatis, basi profunde lobatis, lobis oblongis, obtusis, 
30 ad 50 cm longis ; nervis subtus valde prominentibus, utrinque 
8 ad 11, patulis, basilaribus deflexis usque ad apicem loborum 
attingentibus ; inflorescentiis longe pedunculatis, spathis oblon- 
gis, acutis, usque ad 12 cm longis et 2.5 cm latis, vetustioribus 
reflexis, spadicis circiter 10 cm longis. 
A large, coarse, glabrous plant, the caudices in old plants up 
to 0.7 m high and 15 cm in diameter. Petioles stout, up to 1 m 
in length, when fresh green and mottled or horizontally striped. 
Leaf -blades oblong-ovate, up to 1 m in length and 45 cm in width 
in the widest part, ' pale-olivaceous when dry, from the tip of 
the basal lobes to the apex attaining a length of 1 m, coriaceous, 
somewhat shining, smooth on both surfaces, the margins pro- 
minently cartilaginous, entire ; basal lobes not spreading, oblong, 
obtuse, attaining a length of 50 cm, the sinus extending to the 
insertion of the petiole, usually narrow, acute; apex obtuse 
to obscurely acuminate, the blade gradually narrowed from base 
to apex; lateral nerves 8 to 11, very prominent on the lower 
surface, spreading at nearly right angles except the basal pair 
which is deflexed and extends quite to the tip of the basal lobes, 
emitting from one to three prominent veins on the outer side; 
reticulations obscure. Inflorescences numerous, their peduncles 
up to 45 cm in length. Tube of the spathe oblong, about 2 cm 
long, the limb at first boat-shaped, oblong, acute or somewhat 
apiculate, about 12 cm long and 2.5 cm wide, white, ultimately 
reflexed and deciduous. Spadix cylindric, erect, up to 10 cm 
in length, the basal pistillate portion about 1.5 cm long and less 
than 1 cm in diameter, the staminate portion 3 to 3.5 cm long, 
cylindric, somewhat thicker than the pistillate portion, the 
appendage acute or acuminate, cylindric, about equalling the 
staminate and pistillate portions of the spadix. Staminate and 
pistillate flowers crowded. Stigmas sessile, subcapitate, scarcely 
lobed. Apex of the anther-bearing body truncate, crenate, 
about 2 mm in diameter, anthers apparently 8 to 10. Fruiting 
spadices ovoid or ellipsoid, when dry about 3 cm long.
