MONOECIA POYLANDRIA. 
ta, plana, pedunculata, 
dimidio-breviore; spa- 
dicibus foemineis stam- 
iniferisque plerumque 
distinctis. 
cumulate, flat, pedun- 
culate spathe; fertile 
and sterile spadix fre- 
quently distinct. 
Sp. pi. 4. p. 480. Walt. p. 224. Mich. 2. p. 188. Pursh 2. p. 399. 
Nutt. 2. p. 222. 
Root tuberous, perennial. Stem 0. Petioles about 1 foot high, sheath- 
ing at base, and inclosing the base of the scape, and sometimes of younger 
leaves. Leaves ternate, leaflets oval-lanceolate, acuminate, entire, glabrous, 
the lateral ones sometimes oblique. Scape 8 — 12 inches high, Spathe at 
base somewhat tubular, expanding at the summit into a flat ovate, acuminate, 
blade. Spadix scarcely longer than the tube of the spathe, bearing gene- 
rally either germs or stamens near the base, the summit thick cylindrical or 
clavate. Berries scarlet, 3 — 4 seeded. 
The sterile and fertile scapes are said to grow from the same root, (Lin.) 
more probably dioecious, (Nutt.) 
The spathe is sometimes purple handsomely striped with white; some- 
times green with a purple border; sometimes green. 
Grows in rich soils generally in shaded places. 
Flowers March. 
4. Virginicum. Lin. 
Stemless; leaves ob- 
long, hastate cordate, 
acute, with the lobes 
obtuse; spathe long, in- 
curved; spadix for a 
long distance from the 
summit bearing sterile 
flowers.

Calla Virginica, Mich. 2. p. 187. 
Root tuberous perennial. Leaves 12 — 15 inches long, slightly acumi- 
nate, entire, very glabrous, cordate, with the lobes sometimes hastate, some- 
times straight, generally obtuse. Petioles nearly 12 inches long, sheathing 
the scape at base. Scapes many from one root 12 — 18 inches long. Spathe 
ong, acutte, slightly repand or undulate along the margin, closely embracing 
the spadix. Spadix nearly as long as the spathe. Berry many seeded. 
Grows in swamps and marshy soils, very common: 
Flowers April-— May 
A. acaule; foliis ob- 
longis, hastato cordatis, 
acutis, lobis obtusis, 
spatha elongata incur- 
va; spadice superne 
longius masculifloro.
