has the intramarginal vein more distant from the margin, and if the neuter organs. 
are filiform, as described by Schott, it can scarcely be S. nubicum, and upon that 
ground, and by reason of its different geographical area, I venture to separate it. 
3. ARIS AUMA, Mart.; Benth. et Hook. f. Gen. Pl. iii. 965, 
Spathe deciduous or decaying in fruit; tube convolute, sometimes 
having reflexed margins at the mouth; limb expanded or hooded. 
Spadix unisexual or bisexual, free, sessile or stipitate, shorter or longer 
than the spathe, bearing flowers at the base only or for 4-2 of its 
length, and sometimes a few subulate neuter organs above the flowers, 
ending in a short or long appendix, which is smooth, somewhat echi- 
nate, or loosely covered with hair-like processes. Flowers unisexual. 
Perianth none. Male flowers usually scattered, 2—4-androus ; fila- 
ments connate ; anthers 2-celled, opening by pores or slits, or the cells 
confluent and opening by one marginal slit. Female flowers densely 
crowded in a cylindric or conical spike. Ovary ovoid or subglobose, 
1-celled ; style short or none; stigma simple ; ovules 1-10, orthotropous,. 
erect ; placenta basal, cushion-like. Fruit a berry, obovoid or sub- 
globose, 1- to few- seeded. Seed subglobose, ovoid, or angular; testa 
rather thick, crustaceous ; albumen copious; embryo axile.—Herbs 
with a tuberous rootstock. Leaves solitary or 2—4 to a plant, trifoliate, 
pedate, or with several leaflets in a whorl; petioles long, sheathing. 
Peduncle solitary, shorter or longer than the leaves. 
Species about 60, chiefly natives of India, extending into the Malay Archipelago, 
China, Japan, and North America.

Specimen seen, glabrous. Spathe-tube 4 in. long, subcylindric ; limb 
6 in, long, lanceolate, tapering into a long subulate tail, probably 
curving over the mouth of the tube. Spadix unisexual, male only

Scattered, 3—4-androus; appendix stout, cylindric, obtuse, slightly 
thickened at its base, smooth.

With the inflorescence are some unattached leaves; one of them with 5 leaflets 
pedately arranged, 51-63 in. long, 13-24 in. broad ; the others with 6-7 distinctly 
radiating leaflets, 8-9 in. long, 23-22 in. broad. The leaflets of both leaves are very 
similar in general appearance, sessile, lanceolate, or elliptic-lanceolate, acuminate to 
a fine point, and tapering to an acute base, with entire margins. Both leaves may 
Possibly belong to the inflorescence, but more complete material is needed to decide, 
as I have never seen a species of Arisaema, having both radiating and pedately 
arranged leaflets ; such a difference has hitherto been considered of sectional value.
