The following seven species (58-64) are closely related, 

 the distinctions between them being mainly those of de- 

 gree. Some of them are known only in cultivation, and 

 are no doubt derived forms; all are connected by nu- 

 merous intermediate garden forms : 



58. negUcta, Horn. Lvs. slightly glaucous, 12-15 

 in. long, ensiform, purple at the base: steni taller, IK- 

 2 ft., many-fld. : spathe valves green below at the flow- 

 ering time, much tinged with purple: outer segments 

 obovate-cuneate, very obtuse, 2 in. long, violet-blue on 

 the margin, whitish veined with blue in the center; 

 beard yellow ; inner segments erect or connivent, ob- 

 long, as large as the outer, pale lilac. June. B.M. 2435. 

 — Known only in cult. 



59. hybrida, Retz. (/. aimena.DC). Differs from /. 

 neijlei-ta by its longer spathe valves, and its pure white 

 or f.iintly lilac-tinted outer segments and style branches. 

 June. — Known only in cult. 



60. GermAnica, Linn. Fig. 1178. Lvs. 1-1 >^ ft. long: 

 stem 2-3 ft. high : spathe valves tinged with purple: 

 outer segments obovate-cuneate. 2-3 in. long; beard yel- 

 low; inner segments as large, obovate, connivent. Cen- 

 tral and S Eu. Early May, June. B.M. 670. B.R. 10:818.

 purple var. ) . - Var. retictilita sub^rba, Hort. Outer seg- 

 ments purplf, veined; inner segments lavender. 



61. squilens, Linn. Lvs. glaucous, 1-1% ft. long: 

 stem 2-3 ft. liiirli : spathe valves subscarious: outer 

 segments ol)iivati.--i-unratc. upper part plain lilac-pur- 

 ple; claw yellow, vi-inicl with lilac" ; beard yellow; inner 

 segments as largi-. ..Ii..vati\ dnll lilac and yellow, or 

 brownish and yellow. C.ntral En. to Caucasus. B.M. 

 787.- Many of the (iirnian Insus .jf cultivators belong to 

 this form. Var. Jacquesiana, Hort. Outer segments dark 

 red-violet, yellow at base; inner segments tawny yellow. 

 Late. One of the best. 



62. sambuclna, Linn. Differs from I. squalens by its 

 less robust habit, narrower segments and elder-like 

 odor. The outer segments are colored and veined with 

 i-Iaret, not lilac, purple; inner segments emarginate. 

 Late May. Central Eu. B.M. 187. — Tall and handsome. 



63. Bilibtti, Fost. Lvs. darker green, more distinctly 

 striated, and more rigid than in /. Germanica ; stem 

 several-headed, 2%-3tt. long: spathe valves ventricose: 

 outer segments obovate cuneate, reddish purple, with 

 many dark veins; beard white, tipped with yellow; in- 

 ner segments orbicular unguiculate, 2 in. broad, bright 

 blue-purple. Late June. Trebizond. — Very near /. Ger- 



64. Cypriina, Foster & Baker. Plants tall, the branch- 

 ing stem being 3 ft. high, bearing many fls. 6-7 in. in 

 diameter: outer segments obovate cuneate, reddish lilac, 

 with thin, darker veins; claw whitish, with greenish 

 brown veins; inner segments oblong-unguiculate, lilac, 

 spotted with reddish brown on the claw. June, July. 

 Cyprus. — Very near /. pallida, from which it differs 

 only by the longer navicular spathe valves, which are 

 not entirely scariose at the flowering time, and the more 

 obovate segments. 



65. atroviol&cea, Lange. Lvs. very glaucous, 1 ft. 

 long: stem equaling the lvs.: spathe entirely scariose : 

 fls. dark violet, very fragrant ; outer segments obovate-
