 from each other by the material available. They are dis- 

 tinguished by slight differences in the Ivs., spathe 

 valves, beard, and form of the segments, as described 

 in the text.

 obovate, pure white in the center, conspicuously veined 

 with lilac towards the margin and on the claw; inner 

 segments very plicate, white tinged with lilac on the 

 margin. B.M. 870. — Known only in cult. Probably de- 

 rived from J. pallida. 



57. Sw6rtU, Lam. {F. aphylla, var. Swirtii, Ker.).

The following seven species (58-04) 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. negl^cta, Horn. Lvs. slightly glaucous, 12-15 

 in. long, ensiform, purple at the base: stem taller, 1>2- 

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

 ering time, much tinged with purple: outer segments 

 oljovate-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, oli- 

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

 -Known only in cult. 



59. hybrida, Retz. (/. aniTena, UC). Differs from /. 

 ne(jlecfa by its longer spathe valves, and its pure white 

 or faintly lilac-tinted outer segments and style branches. 

 June, — Known only in cult. 



00. Germinica, Linn. Fig. 1178. Lvs. 1-lM 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 SEu. Early May, June. B.M. 670. B.R. 10:818. 

 I.H. 40:182 (var. Gypsea, purewhite). Gn. 48:1033 (dark 

 purple var.). — Var. reticulata sub6rba, Hort. Outer seg- 

 ments purple, veined; inner segments lavender. 



61. squalens, Linn. Lvs. glaucous, 1-1>2 ft. long: 

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

 segments obovate-cuneate, upper part plain lilac-pur- 

 l>le; claw yellow, veined with lilac; beard yellow; inner 

 segments as large, obovate, dull lilac and yellow, or 

 brownish and yellow. Central Eu. to Caucasus. B.M. 

 787. — Many of the German Irises of cultivators belong to 

 this form. Var. Jacquesl^na, Hort. ()uter segments dark 

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

 Late. One of the best. 



62. sambucina, Linn. Differs from /. i^qiialevH by its 

 less robust habit, narrower segments and elder-like 

 odor. The outer segments are colored and veined with 

 claret, 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 m()re rigid than in /. Gernianica : stem 

 si-veral-headed, 2^2-3 ft. long: spathe valves ventricose: 

 outer segments obovate cuneate, reddish purple, with 

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

 ner segments orbicular ungTiiculate, 2 in. broad, bright 

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

 III on tea . 



04. Cypri^na, 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 wliitish, with greenish 

 lirown veins; inner segments oblong-unguiculate, lilac, 

 spf.tted with reddish brown on the claw. June, July. 

 ( 'yprus, — Very near /. pallida, from which it differs 

 only by the longer navicular spathe valves, which are 

 not CTitirely scariose at the flowering time, and the more 

 obovate segments. 



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

 Ion;.'; stem equaling the I VS. : spathe entirely scariose : 

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