 ing and slender dark red slightly 

 curved spadi.\, the whole "Hower" 

 often measuring 3 ft. long. Cochin 

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

 known species in Ainer. gardens. 

 Has a strung and disagreeable odor, 

 campanulatus, Blume. Stanley's

 less ) : spatbe nearly or quite 2 ft. 

 broad and 15 in. high, with a hori- 

 zontal, spreading fluted bor-

 on the margin and grayish, 

 spotted white lower down, and 

 becoming purple in the cen-

 the purple top enlarged and 

 convoluted: If. much as in -4.

gigant^us, Blanc. "PI. larger 

 than .1. rawpinniliifiix (often 2 



ing in color, slunliim- ficiii drrp 

 red to cream iMlor towar.ls 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 

 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. 

 campaiiiilntua ! Probably not the A. gigaiitetis of Blume. 

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

 golileu 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 Arisseraa.

AMPEL6PSIS (Greek ampelos, vine, and opsis, like- 

 ness). Mli'ienr. Shrubs, climbing by tendrils opposite 

 the Ivs.: Ivs. alternate, petioled, digitate, bipinuate 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 elimldng vines, thriving in almost any soil. 

 Pnip, by seiils :ind by hardwood or greenwood cuttings. 

 A. iiiiiiiijiii folia is usually increased by hardwood cut- 

 tings, while A. tricm^pidata 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,

 walls, clinging firmly, growing more straight upward

 to a brilliant orange and scarlet in fall. Probably the 

 favorite of all hardy vines in cities.
