514 MONOECIA MONANDRIA. Calla, 



their whole length,scape included, scarcely half the length of 

 the petioles, the usual bractes intervene between the round, 

 smooth, uniform, green scapes. Spatlie sub-cylindric, rather 

 obtuse, with an acumen, smooth on both sides, of a pale 

 greenish yellow. Spadix sub-cylindric, obtuse, equalling, 

 or rather longer than the spathe ; the upper two thirds co- 

 vered with sessile, many-celled anthers ; the lower third with 

 the germs intermixed with about as many abortive stamina 

 as there are germs. Germs ovate, seemingly two, or three- 

 celled, but as the receptacles are parietal and do not unite in 

 the centre, I can call them only one-celled ovula, many at- 

 tached to the exterior half of the parietal receptacles. Style 

 none. Stigma two or three-lobed. Berries oblong, not un- 

 like a large berberry, and rarely containing more that a sin- 

 gle seed. 



Is readily multiplied, by offsets from the body of the root,

Arisarum esculentum. Rumph. Amh. v. t. lll.y. 1. 



A native of Amboyna, from thence introduced into the Bo- 

 tanic garden, where it blossoms in May. 



Root a small, oblique, oblong tuber with ramous fibres. 

 Stem none. Leaves oblong, cordate, smooth on both sides, su- 

 bulate, pointed, with a single slender vein round the margin ; 

 from five to seven inches long, and about three broad. Pe- 

 tioles sub-cylindric, shorter than the leaves. Scape shorter 

 than the sheathing portion of the petioles, which embrace it on 

 opposite sides. Spathe a little longer than the spadix, at the 

 base roundthe germs convolute and green ; the upper portion 

 separating and dropping from the lower, when the anthers 

 begin to discbarge their pollen, splitting round the base into 

 various portions, is of a tender somewhat lleshy texture, a
