520 CXXXIV. ARACEtE. Calla. 



the edge. Scape 8 — 12' high, erect, round, embraced at the base by the long 

 sheaths of the petioles. Leaves 2, on long stalks, each consisting of 3 smooth 

 leaflets, 2 — 7' long, h as wide. Spathe green without, usually variegated within 

 with stripes of dark purple alternating with pale green. Spadix much shorter 

 than the spathe varying from green to dark purple. Fruit a bunch of bright 

 scarlet berries. The corm loses its fiercely acrid principle by drying, and is 

 then valued as a carminative, &c. May, June.

Acaulescent; //. mostly solitary, pedate ; Ifts. oblong-lanceolate; spadix 

 subulate, longer than the convolute, oblong spathe. — Less common in N. Eng. 

 than the former species, found in wet places, banks of streams, U. S. Stem a 

 fleshy, subterraneous corm. Scape slender, 6 — 12' high. Leaf on an erect, 

 sheathing petiole, which is dichotomous above, each half bearing 2 — 4 leaflets 

 with an odd one at the fork. Leaflets rather smaller than in A. triphyllum. 

 Spathe green, 1 — 2' long, rolled into a tube at base. Spadix slender, with its 

 long, tapering point much exserted. Fruit a bunch of red berries. June, July. 



2. PELTANDRA. Raf. 

 CrT. tteXtti, a shield or target, avdpss, stamens ; from the character. 



Spathe convolute ; spadix covered with flowers, staminate above, 

 pistillate below ; perianth ; stamens peltate ; berry 1-celled, 1 -seed- 

 ed.— ^2;. 



P. ViRGiNiCA. Raf. (Arum. Linn. Calla. Bw. Lecontia. Cooper. Rensse- 

 laeria. Beck. Caladium. Lindl.) — Acaulescent; Ivs. oblong, hastate-cordate, 

 acute at apex, the lobes obtuse ; spathe elongated, incurved ; spadix covered with 

 staminate flowers the greater part of its length. — A smooth, dark green plant, 

 in wet grounds, N. Y. and Ms. to Car. Leaves radical, numerous, 8 — 12' long, 

 h as wide, on petioles as long as the scapes. Scapes many from the same root, 

 8 — 15' long. Spathe closely involving the spadix, green, 2 — 3' long, lanceolate, 

 wavy on the margin. Spadix slender, acuminate, shorter than the spathe, 

 bearing the ovaries and finally the berries in a dense cluster at its base. June. 

 It is to be hoped that this persecuted plant will soon find, if it has not here found, 

 a permanent abode. Jl.
