144 CL. AROIDEE (BROWN). [ Arisema. 
41-81 in. long, 3-1} in. broad, tapering to a long acuminate apex, and 
to an acute base, margins distinctly and acutely serrulate, with the 
teeth directed towards the apex, glabrous on both sides. Peduncle 
longer than the petioles, glabrous. Spathe 5-7 in. long; tube sub- 
ylindric ; limb about twice as long as the tube, oblong-lanceolate, 
tapering into a linear-subulate tail. Spadix unisexual, a little longer 
than the tube, flowers densely crowded; appendix stout, straight, 
cylindric, obtuse, slightly thickened at its base, slightly tapering 
upwards, smooth.—Schott, Prod. Aroid. 47; Engl. in DC. Monogr.

This species was distributed as A. enneaphyllum, Hochst., but is easily distin- 
guished by its sharply serrulate leaves, with the teeth all directed towards the apex ; 
in A. enneaphyllum the teeth are more minute, irregular, and more or less directed 
outwards.

Leaves 2-3 to a plant ; petioles long, sheathing; leaflets 5—, radiating, 
sessile, 2-6 in. long, 1-2 in. broad, lanceolate or elliptic-lanceolate, 
acuminate, cuneate-acute at the base, minutely erose-denticulate on the 
margins, glabrous on both sides. Peduncle longer than the petioles, 
glabrous. Spathe 34-6 in. long; tube cylindric or subcampanulate, 
rather more than half as long as the ovate, acuminate limb. Spadix 
14-2} in. long, scarcely longer than the tube of the spathe, unisexual, 
usually stipitate; flowers densely crowded ; appendix moderately 
stout, straight, cylindric, slightly tapering at the base (always?), 
smooth.—Schott, Syn. Aroid. 28, and Prod. Aroid. 46; Engl. in DC.

Spathe convolute or very rarely connate into a tube below, persis- 
tent, withering. Spadix free, monecious, with a terminal appendage: 
male and female parts usually contiguous, rarely distant ; neuter organs 
none. Perianth none. Ovaries in 2 to many series, usually crowded 
ona cylindric spike, 1—4-celled, with or without a style; stigma entire or 
2—4-lobed. Ovules solitary in each cell, basal, anatropous. Anthers sessile 
or subsessile, densely crowded or rarely scattered on a cylindric or obconic 
spike ; cells contiguous, opening by 2-4 apical pores. Berries sub- 
globose or ellipsoid. Seed ellipsoid or plano-convex, albuminous ; testa 
thin ; embryo seated at the base of the copious albumen and exterior 
to it.—Perennial herbs. Rootstock a tuber. Leaf solitary, not pro 
duced at the time of flowering ; petiole tall, erect, 3-branched at the 
apex; branches 1-3 times dichotomously divided, pinnatipartite ;
