grandlfldra, Sweet. Glabrous and glaucous, 1-3 ft. 

 high, almost destitute of prickles: Ivs. sinuate-pinnatifid, 

 the lobes only weakly spinescent : bracts scattered along 

 the fl. branches: capsule valves scarcely crested. S. W.

 the Ivs. glaucous ; Ivs. sinuate-pinnatifid, spiny : fl.- 

 bracts aggregated below the fls. : petals large (rarely 

 purple) : capsule valves crested or spiny. Mes. to Colo.

AB6YB£IA {silver!/, referring to the under side of 

 the Ivs.). Coni'olvuldcew. Tender climbers from the 

 orient, allied to Ipomoea. Lvs. usually large, silvery, 

 tomentose or villous beneath : cymes usually few-fld. 

 They require too much room before flowering to be popu- 

 lar here. A . cuneata is one of the dwarf est and most florif- 

 erous kinds. Light, rich soil. Prop, by cuttings or seeds.

ARIS.SMA (Greek-mjide name, of no particular sig- 

 nificance). Aroiileir. About 60 widely aistributi-d herbs, 

 with tuberous roots, autl a spathe rolled in or convolute 

 about the spadix below, ami often arched over it : Hs. 

 unisexual, the pistillate on the lower part of the spadix, 

 and each consisting of a 1-loculed ovary, and generally 

 ripening into a showy berry. Some species are native, 

 and several of them are hardy in the open ; others are 

 cult, undercover, as recommended for Arum (which see).

covered by the arching purplish spathe. Common in 

 woods. G.W.F. 28. D. 281. — Tuber or corm flatfish and 

 large, very acrid, often employed as a domestic remedy. 

 Berries red and showy, ripening in early summer. 

 Planted in a moist, shady place, the lvs. remain until 

 fall ; but in exposed places they die down early in sum- 

 mer. This and the last are very interesting native 

 plants of easy culture, propagated by tubers and by 

 seeds. 



fimbri^tum, Masters. Fringed Calla. Leaf solitary, 

 the petiole a ft. or less high, sheathed below ; Ifts. broad- 

 ovate and acuminate, short-stalked : scape as long as 

 the petiole, bearing a large, purple-limbed, white- 

 streaked, long-pointed spathe : spadix ending in a long 

 and gracefully drooping, feather-like appendage. E.

-A handsome and striking pot-plant, blooming in sum- 



iier. Grow in rich soil. Dry off the tuber when the lvs. 



urn yellow after flowering, and keep dry in sand or 



arth until spring. 

 Other species are: A. anOmalum, Tiemsl. Lfts. 3, broad-ovate,

ARISARUU (old Greek name). Ardidem. Three or 

 four variable species of Arum-like plants of the Medi- 

 terranean region. Differs from Arisfema, its nearest 

 ally, in having the margins of the spathe connate rather 

 than convolute, and in other technical characters. For 

 culture, see Aris<ema and Arum.
