1. ARISiE'MA, Martins. Dragon-root. Indian Turnip, {apov, 

 arum, arpa, a sign.) Spathe convolute at base, limb arched or some- 

 what plain ; spadix covered with flowers below, naked and elongated 

 above ; flowers diclinous, achlamydeous ; $ above the fertile, each flower 

 consisting of 4 or more stamens with anthers opening at top ; $ ovary 

 1-celled ; stigmas depressed; ovules 2 to 6, orthotropous, erect from the 

 base of the cell ; berry red, 1 or few-seeded. — 21 Scape arising from a 

 a corra or tuberous rhizome, sheathed with petioles, of the radical, 

 veiny Ivs. (Arum, L.) 



1 A. triph^llum L. Jack-in-the-pulpit. Acaulescent ; hs. trifoliate, mostly 

 in pairs, leaflets oval, acuminate; spadix clavate, obtuse; spathe ovate, acuminate, 

 flat and inflected above. — A curious and well known inhabitant of wet woodlands, 

 Can. to Ga. W. to the Miss. The stem is a rugous, fleshy, subterraneous corm 

 giving off radicles in a circle from the edge. Scape 8 — 12' high, erect, round, 

 embraced at the base by the long sheaths of the petioles. Leaflets, 2 — 1' long, 

 J as wide. Spathe green without, usually variegated within with stripes of dark 

 purple alternating with pale green. Spadix much shorter than the spathe, vary- 

 ing 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 carmina- 

 tive, &c. Apr., Jn. (Arum, atrorubens Ait.) 



2 A. quin^tum. Acaulescent ; Ivs. with very long sheaths, in pairs one or both 

 qiiinate; Ifts. oval-lanceolate, acuminate, narrowed at base to a short petiole or 

 sessile ; spadix long and slender, nearly inclosed in the ovate-lanceolate spathe, 

 which is briefly inflected at the pointed apex ; berry 1 to 2-aeeded. — Ga. and S. 

 Car. (Curtis.) Scape 1 to 2f high. Lvs. with long petioles and still longer sheaths. 

 Ltte. 5 to 10' long, spathe 3 to 5' (Arum quinatum Nutt.) — Perhaps identical with 

 A. pentaphyllum (Schott.) of India. 



/3, OBTcrso-QUiNATUM. Lfts. rounded-obtuse, mucronate, abruptly narrowed to 

 a long petiolule. — Georgia (Feay, Pond). 



3 A. Drao6ntium Schott. Green Dragon. Acaulescent; If mostly solitary, 

 pedate; Iftg, 7 to 11, oblong-lanceolate; spadix subulate, longer than the convo- 

 lute, oblong spathe. — Less common in N. Eng. than the former species, found in 

 wet places, banks of streams, XT. S. Stem a fleshy, subterraneous corm. Scape 

 slender, 10' to 2 f high. L^af on an erect, sheathing petiole, which is dichotomoua 

 above, each half bearing 2 — 4 leaflets with an odd one at the fork. Leaflets 5 to 

 8' long, one-third as wide. 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. Jn., Jl. (Aram Dracontium L.) 



2. PELT'ANDRA, Raf. (Gr. toXtt/, a shield or target, avSpeq) 

 Spathe convolute ; spadix covered with flowers, staminate above, pistil- 

 late below ; perianth ; anthers 8 to 12', attached to the margin of a 

 peltate, oblong, connectile, and opening by a terminal pore ; berry 1- 

 celled, 1 to 3-seQded. — 11 Et. fibrous. Lvs. sagittate. 

 1 P. Virgfnioa Eaf Acaulescent; lvs. oblong, hastate-sagittate, acute at apex, 

 the lobes obtuse; epathe elongated, incwrved, green, wavy on the margin; spadix 

 covered with staminate flowers the greater part of its length. — A smooth, dark 

 green plant, in wet grounds, N. T. and Ms. to Car. Leaves radical, numerous,
