Bivi^ri, Dur. Devil's Tongue. Snake Palm. Pig. 79. 

 Scape (sent up in early spring) preceding the lvs.,3-4ft., 

 darli colored and speckled with light red : If. often 4 ft. 

 across, pedately decompound, the petiole mottled, stand- 

 ing on a stalk like an umbrella : spathe 

 rosy, calla-Iike, with a long-project- 

 ing and slender dark red slightly 

 curved spadix, the whole "flower" 

 often measuring 3 ft. long. Cochin 

 China. R.H. 1871, p. 573. -The best 

 known species in Amer. gardens. 

 Has a strong and disagreeable odor. 

 campanulitUB, Blume. Stanley's 

 Wash Tub. Scape lower (2 ft. or 

 less) : spathe nearly or quite 2 ft. 

 broad and 15 in. high, with a hori- 

 zontal, spreading fluted bor- 

 der (not calla-like) , red-purple 

 on the margin and grayish, 

 spotted white lower down, and 

 becoming purple in the cen- 

 ter : spadix 10-12 in. high, 

 the purple top enlarged and 

 convoluted : If. much as in A . 

 Mivieri: tuber weighing 8-10 

 lbs., shape of a flat cheese. An 

 old garden plant from E. Ind.

gigantSus, Blanc. "PI. larger 

 than A. campanulatus (often 2 

 ft. across) and much more pleas- 

 ing in color, shading from deep 

 red to cream color towards the 

 center. The club-shaped spadix 

 is dark maroon, with yellow and 

 red base. After flowering, the 

 foliage -stem appears,— a stout 

 stem of deep green color, mottled 

 with gray. After growing at the 

 Amorphophallus Rivieri. rate of several inches a day, it ex- 

 pands into a large palm-like leaf, 

 of a rich, dark green color, often measuring 5 ft. across." 

 Blanc, 1892, received "under this name from India." A. 

 campanulatus f Probably not the A.giganteus of Blume. 

 Simlense, Blanc. "PI. 15 in. long, the inside of peculiar 

 golden color, spotted purple ; the back is metallic brown. 

 Fine palm-like foliage." The cut in Blanc's catalogire 

 shows a spathe produced into a long foliaeeous summit, 

 and a long, slender, recurved spadix. Probably of some 

 other genus : very likely an Arisema.

AMFELCFSIS (Greek ampelos, vine, and opsls, like- 

 ness). Vitdcece. Shrubs, climbing by tendrils opposite 

 the Ivs. : Ivs. alternate, petioled, digitate, bipinnate or 

 simple : corymbs opposite the Ivs. or terminal ; fls. per- 

 fect, greenish and small ; petals and stamens usually 5 : 

 fr. a 1-4-seeded berry. Allied to Vitis, but easy to dis- 

 tinguish, even in the winter state, by its bark bearing 

 lenticels and the white pith of the branches, while Vitis 

 has a shredding bark and brownish pith. About 20 spe- 

 cies in N. Amer., E. Asia and Himal. Hardy and orna- 

 mental climbing vines, thriving in almost any soil. 

 Prop, by seeds and by hardwood or greenwood cuttings. 

 A. quinquefolia is usually increased by hardwood cut- 

 tings, while A. tricuspidata grows best from seeds 

 planted under glass or out-of-doors ; also from green- 

 wood cuttings in spring or early summer, under glass. 

 Layers also root readily. All species may be prop, by

 growth, coloring bright scarlet in autumn ; the varieties
