ARISARUM 



AA. Fls. white (rarely purple). 



grandifldra, 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. 

 Mex. B.R. 1264. L.B.C. 16:1546. B.M. 3073. 



platyceras, Link & Otto. Robust, 1^-4 ft., very spiny, 

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

 bracts aggregated below the fls. : petals large (rarely 

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



Var. hispida, Prain. (A. hispida, Gray). Petals 

 rounded ; sepals and capsule densely prickly : plant 

 hispid. Wyo. and Ark., W. and S. L. H. B. 



ARGYREIA (silvery, referring to the under side of 

 the Ivs.). Convolvuldcece. Tender climbers from the 

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

 tomentose or villous beneath : cymes usually few-fid. 

 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. 



tiliaefdlia. Wight. Lvs. heart-shaped : fls. white and 

 violet. Prop, from seeds. E. Ind.-Int. 1890 by Peter 

 Henderson & Co. 



ARIA. See Sorbus. 



AA. Leaflets S. 



triphyllum, Torr. JACK-IN-THE-PULPIT. INDIAN TUR- 

 NIP. Fig. 137. Usually dioecious : Ivs. usually 2, with 

 ovate or elliptic-ovate Ifts. : spadix club-shaped and 



(Greek-made name, of no particular sig- 

 nificance). Arbidew. About 60 widely distributed herbs, 

 with tuberous roots, and a spathe rolled in or convolute 

 about the spadix below, and often arched oVer it : fls. 

 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, under cover, as recommended for Arum (which see).

A. Leaflets 7-11. 



Drac6ntium, Schott. DRAGON-ROOT. Sending up a 

 solitary leaf 1-2 ft. high, pedately divided into oblong- 



137. Jack-in-the-Pulvit. Arisaema triphyllum (X 



lanceolate pointed Ifts. : spadix long-pointed and pro- 

 jecting beyond the greenish spathe : scape much shorter 

 than the leaf. Low grounds in E. Amer.- Occasionally 

 grown in borders and rockwork. 



138. Aristolochia macrophylla. 



covered by the arching purplish spathe, Common in 

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

 large, 1 very acrid, often employed as a domestic remedy. 

 Berries red and showy, ripening in early summer. 

 Planted in a moist, shady place, the Ivs. 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. 



fimbriatum, 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. 

 Ind. G.C. 11.22:689; III. 15:763. B.M. 7150. Mn.8:59. 

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

 mer. Grow in rich soil. Dry off the tuber when the Ivs. 

 turn yellow after flowering, and keep dry in sand or 

 earth until spring. 



Other species are: A. anomalum, Hemsl. Lfts. 3, broad-ovate, 

 acuminate : spathe small, purplish and streaked, arching over 

 the short spadix : suggests A. triphyllum. Malacca. B.M. 7211. 

 A. conclnnum, Schott. Leaf solitary, with 10 or more Ifts.: 

 spathe colored, tailed. India. B.M. 5914. A.curvatum, Hook. 

 =A. tortuosum. A. galeatum, N. E. Br. Leaf solitary, with 3- 

 Ifts.: spathe purple inside. India. B.M. 6457. A. Griffithii, 

 Schott. Lvs. 2, Ifts. 3, nearly orbicular : spathe very large, with 

 a spreading and wrinkled limb several inches broad, and rich 

 purple with green veins. India. B.M. 6491. One of the hand- 

 somest of all Arissemas. A. nepentholdes, Mort. Leaf pedate, 

 of 5 narrow Ifts.: spathe auricled. India. B.M. 6446. A. ringens, 

 Schott. Lfts. 3, ovate, acuminate : spathe purple, arched. Japan. 

 Perhaps hardy in the open. Gn. 37, p. 577. A. Sieboldii, De 

 Vriese.=A. ringens. A.specibsiim, Mort. Lfts. 3 : spathe large 

 and very dark purple ; spadix with a very long, string-like tip. 

 India. Gn. 37: 758. B.M. 5964. A. tortuosum, Schott. Lvs. usu- 

 ally 2, with several or many Ifts.: spathe purple outside : spa- 

 dix long-tailed but erectish, greenish. India. B.M. 5931 (as A. 

 curvatum). A. utile, Hook. Lvs. 2, with 3 crenate Ifts. : spathe 

 reddish, green-ribbed : spadix purple : tubers eaten by natives 

 in India. B.M. 6474. A. Wrayi, Hemsl. Leaf solitary, pedate, 

 the Ifts. lanceolate : spathe green or whitish : spadix slender, 

 recurved. India. B.M. 7105. Except A. ringens, probably all 

 the above species require pot cult, in the N. L jj < 3^ 



ARISARUM (old Greek name). Aroidece. Three or 

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

 terranean region. Differs from Arisaema, its nearest 

 ally, in having the margins of the spathe connate rather 

 than convolute, and in other technical characters. For 

 culture, see Ariscema and Arum.
