500 MONOECIA MONANDRIA. Arum. 
Ihave not found any of the small bulbs so common in A. In- 
dicum, which this species resembles so much, Stem simple, 
straight, as thick as a man’s arm, height of the stem in two 
years about two feet, marked with the circular cicatrices of 
the fallen leaves ; height of the whole plant, to the top of the 
leaves, from six to eight feet. Leaves, cauline petioled, ovate, 
cordate, cloven at the base ; apex obtuse with an incurved 
point, lobes rounded ; margins somewhat waved, polished on 
both sides; rib and vein large and elevated underneath ; from 
two to four feet long, by two or three broad, Petioles from 
two to three feet long, the lower half sheathing ; the upper 
part sub-cylindric, smooth, polished, of an uniform green in 
every part. Peduneles axillary, intermixed with some spathi- 
form bractes, nearly round, rather shorter than the petioles, 
one-flowered, regularly two in each axill. Spathe erect, the 
lower part thick, gibbous, convolute and permanent; the ex- 
terior portion boat-shaped with a short acute apex, both sides 
smooth and of a‘ pale green colour, this portion drops soon 
after flowering time, while the lower portion remains till 
the seeds are ripe, Spadix nearly as long as the spathe, sub- 
cylindric, club about one third part the length of the whole 
spadix. Nectaries, many flat, rhombiform glands on the con- 
tracted part of the spadix, between the germ and the spa- 
dix, Anthers numerous, rhombiform, with ten or twelve pol- 
liniferous ones round the margin cells, these open by a slit on 
the outside of their apices. Germs numerous on the conic 
base of the spadix, four-celled, with two or three ovula in 
each attached to the bottom of the cell. Style none. Stigma 
roundish, Berry numerous, size of a small cherry, shape 
more or less round according to the number of seeds, smooth, 
ofashining scarlet, one-celled, the growth of the seeds having 
destroyed every vestige of the partitions which were present 
in the germ. Seeds generally from one to four, roundish, 
smooth, Integument single, in the recent state soft and spon- 
gy. Perisperm conform to the seed, cartilaginous. Embry? 
simple, obconical, with the obtuse end close to the apex of 
the seed and there not covered by the perisperm.
