Rivieri, Dur. DEVIL'S Tosr.uE. SNAKE PALM. Fig. 79. 

 Scape i sent up in early spring) preceding the Ivs., .'{-4 ft., 

 dark 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-like, with a long-project- 



i 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, 

 campanulatus, 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 . 

 Rivieri: tuber weighing 8-10 

 Ibs., shape of a fiat cheese. An 

 old garden plant from E. Ind.

 1872:1720, 1721 ; III. 5:755. 



griganteus, Blanc. "Fl. 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. 

 <-ii mpn H H latus ? Probably not the A . giganteus of Blume. 

 Simlense. Blanc. "Fl. 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 catalogue 

 shows a spathe produced into a long foliaceous summit, 

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

 other genus : very likely an Arisaema. 



A. Afzelii, Hort. (Corynophallus Azelii, Schott) = Hydrosme 

 Leonensis. A. Elchleri, Hook. f. Spathe 2 in. across, purple and 

 white : spadix 5 or 6 in. high, thick, brown : If. single, much di- 

 vided. W. Afr. B.M. 7091. A. Lacourii, Linden. (Pseudodra- 

 fontiumLaoourii.N.E.Br.). Petioles barred with yellow ; blades 

 much cut. green, spotted white. Cochin China. I.H. 25: 316. 

 A. Leopold/cunts, Nicholson (Hydrosme Leopoldiana, Masters). 

 Spathe reddish, long acuminate on one side, with undulate mar- 



fins; spadix 2-3 ft., terete, recurved : If . 2-3 ft. across. Congo. 

 .H. 34 :23 ; 42, f. 49. A. nivosus, Lem., I.H. 12: 424 = Dracon- 

 tium asperum. A. Titanum, Beccari. One of the most remark- 

 able plants known. Tuber 5 ft. in circ. : If.- stalk 10 ft. : If.- blade 

 45 ft. in circ. : spathe 3 ft. in diam. : spadix 6 ft. high. Bloomed 

 at Kew in 1890, the tuber dying thereafter. Sumatra. B.M.

AMPELOPSIS (Greek ampelos, vine, and opsis, like- 

 ness). Vitacece. 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 



cuttings with a good eye placed in sandy soil under bell- 

 glasses, in Sept. Monogr. by Planchon'in De Candolle, 

 Monographiee Phanerogamarum, 5:447-463. Cf. Cissus. 



A. Tendrils mostly disk-bearing : berries dark purple 

 irifh blue bloom, pea-sized. (Pa*ikenoti*g*t.) 



quinquefdlia, Michx, (A. hederacea, DC. Vitis quinque- 

 folia, Lam.). VIRGINIA CREEPER. Fig.80. High-climbing: 

 Ivs. digitate ; Ifts. usually 5, elliptic or oblong-obovate, 

 coarsely serrate. N.Amer. Em. 2: 535. Var. laaitantis- 

 sima, Rehder. Young branches and Ifts. beneath pubes- 

 cent : tendrils with many ramifications and well devel- 

 oped disks. Var. murdrum, Rehder. (A. hederdcea, var. 

 inurbrum, Focke. A.murbrum and muralis, Hort.). In- 

 florescence and tendrils like the former ; Ifts. glaucous 

 and glabrous beneath. Var. Engelmanni, Hort. Similar 

 to the last, with smaller and more dense foliage. Var. 

 latifdlia, Dipp. (A Rdylei, Hort. ) . Of vigorous growth : 

 Ivs. very large, shining. Var. Graebneri, Rehder. Pubes- 

 cent, intense scarlet in fall. Gt. 48: 1462. Var. vitacea, 

 Knerr. Aerial roots none, and the tendrils scarcely disc- 

 bearing : berries large and early. Mich, to Kans. Does 

 not cling to walls. A very valuable climber of vigorous 

 growth, coloring bright scarlet in autumn ; the varieties 

 radicantissima and murorum well adapted for covering 

 walls, clinging firmly, growing more straight upward 

 than the following species. 



tricuspidata, Sieb. & Zucc. (A. Veitchi, Hort. A. 

 Rdylei, Hort. Vitis inconstans, Miq.). JAPANESE IVY. 

 BOSTON IVY. Figs. 81, 82. High-climbing, with short 

 and disciferous tendrils : Ivs. 3-lobed or 3-foliolate, 

 coarsely and remotely dentate, shining and glabrous on 

 both sides : racemes short-stalked. China, Jap. R.B. 

 1877: 11. Gng. 4: 353, 1: 373.-A hardy and very useful 

 climber, clinging firmly and covering walls densely ; 

 the glossy foliage stands dust and smoke well, and turns 

 to a brilliant orange and scarlet in fall. Probably the 

 favorite of all hardy vines in cities. 



AA. Tendrils without disks : not climbing very high. 

 B. Lvs. not lobed or rarely tricuspidate. 



cordata, Michx. ( Vitis indivlsa, Willd. Cissus Am- 

 pel6psis,Pers.). Nearly glabrous : Ivs. cordate, round- 

 ish-ovate, acuminate, acutely serrate : berries bluish or 

 greenish. From 111. and Ohio south. 



BB. Lvs. 3-5-lobed or divided. 



heteroph^lla, Sieb. & Zucc. Lvs. cordate, slightly 3- 

 or deeply 3-5-lobed, nearly glabrous and shining be- 

 neath, lobes serrate or incised : berries light blue, punc-

 for covering rocks and low trellis work ; handsome in 

 autumn, with its freely produced light blue berries.
