ARISARUM (old Greek name). Arace;e. Three or 

 four variable sjjecies of arum-like plants of the Medi- 

 terranean region. Differs from Arisa;ma, its nearest 

 ally, in having the margins of the spathe connate rather 

 than convolute, and in other technical characters. For 

 culture, see Arum. 



vulgare, Targ. (Ariim Arimrum, Linn.). A foot high: 

 lvs. cordate or somewhat hastate, long-stalked: spathe 

 purple, incurved at the top. — Has many forms and 

 names. Can be grown in the open with protection. 



.4. proboscUeum, Savi. Lvs. hastate; scape less than half the 

 petiole: spathe 1-1 )i in. long, pale gray, with a long olive tail 5-6 

 in., the moutli of spathe small, olive-purple. Italy. B.M. 6634.

ARISTEA (name refers to the stiiT leaf-points). Iri- 

 da^esp. Mostly blue-flowered spring- or summer-bloom- 

 ing greenhouse herbs or sub-shrubs, and grown in the 

 open far south. 



Leaves distichous in basal rosettes, those on the st. 

 alternate: fls. clustered in spikes, not lasting; the 

 perianth with a short tube and oblong, spreading, 

 nearly equid segms. that twist up spirally after flower- 

 ing; stamens short-stalked, borne on the throat of 

 perianth-tube: fr. an oblong or cylindrical 3-valved 

 caps.— About 30 species in Afr. Of easy cult. Prop, by 

 seeds and division. Not showy. 



Ecklonii, Baker. Herb, IH ft.: lvs. linear but not 

 rigid, 18 in. or less long: fls. in many clu.sters that form 

 a loose panicle with a flattened rachis; hmb of blue 

 perianth H'm. long: caps, cyhndrical, less than 1 in. long. 

 Cape Colony. — Reported in Cahf., where it is said to 

 make dense dark green clumps, with Sisyrinchium-like 

 fls. in spring. 



fruticosa, Pers. {Niv'enia frulicdsa, Baker). Dwarf 

 shrub: st.-lvs. linear, 2 in. or less long: fls. in a single 

 cluster; perianth blue, the tube J^in. long. Cape 

 Colony. L. H. B. 



ARISTOLOCHIA (named for supposed medicinal 

 virtues). Arislolochiacese . Birth wort. Perennial herbs 

 or shrubs, many climbing, remarkable for the very odd- 

 shaped flowers, some species grown in the open, but 

 most of them culti- 

 vated as odd glass- 

 house subjects. 



The corolla is 

 wanting, but the 

 calyx is corolla-like, 

 tubular, mostly vari- 

 ously bent, and com- 

 monly tumid above 

 the ovary and con- 

 tracted at the mouth, 

 superior; stamens 

 commonly 6, short 

 and adnate to the 

 style, which is flefhy 

 and lobcd: fr. a 

 naked 6-valved caps. ; 

 seeds flat. — About 

 180 species of warm 

 and temperate regions throughout the earth; mostly 

 woody twiners. Many si)ecies are evergreen. The 

 tender species are cult, for the strikingly irregular 

 and grotesque fls. The fls. arc u.sually fetid in odor, 

 often very disagreeable. .Many species are grown in 

 botanic gardens and in the collections of fanciers, but 

 those usually cult, or planted are to be found in the 

 treatment which follows. 



These plants are mostly climbing vines, A. macro-
