 ments as large, white. Cent, and S. Eu. B.M. 671. Gn.

 violet, rarely white ; outer segments obovate-cuneate, 

 3% in. long; inner segments orbicular. Differs from /.

 38:441. Var. speciosa, Hort. Tall, with large, light blu< 

 flowers. 



56. plicata, Lam. (7. apliylla, var. plicata, Ker.) 

 Rhizome, stem and Ivs. as in 7. pallida: outer segments 

 obovate, pure white in the center, conspicuously veinec 

 with lilac towards the margin and on the claw; innei 

 segments very plicate, white tinged with lilac on th( 

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

 rived from 7. pallida. 



57. Swertii, Lam. (7. aphylla , var. Swertii, Ker.). 

 Much dwarfer than /. florentina and I. pallida. Steir 

 1-1% ft. long: spathe valves flushed with violet: outei 

 segments 2-2% in. long, obovate-cuneate, white, faintlj 

 veined and flushed with purple on the margin; innei 

 segments as large, much crisped, pure white, except the 

 purple keel and margin. Fls. May and June, long befon 

 7. pa llida. Fragrant. Known only in cult. 



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, anc 

 are no doubt derived forms; all are connected by nu 

 merous intermediate garden forms : 



58. neglecta, Horn. Lvs. slightly glaucous, 1 

 in. long, ensiform, purple at the base: stem taller, 



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. (7. amcena, DC.). Differs from 7. 

 neglecta by its longer spathe valves, and its pure white 

 or faintly 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. 

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

 purple var.) . Var. reticulata suberba, Hort. Outer seg 

 ments purple, veined ; inner segments lavender. 



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

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

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

 ple; 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. Jacquesiana, Hort. Outer segments dark 

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

 Late. One of the best. 



62. sambucina, Linn. Differs from 7. squalens 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. Bili6tti, Fost. Lvs. darker green, more distinctly 

 striated, and more rigid than in 7. Germanica : stem 

 several-headed, 2%-3ft. 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 7. Ger- 

 manica. 



64. Cypriana, 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 lil 

 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 7. pallida, from which it din 

 only by the longer navicular spathe valves, which are 

 not entirely scariose at the flowering time, and the m 

 obovate segments. 



65. atroviolacea, Lange. Lvs. very glaucous, 

 long: stem equaling the Ivs.: spathe entirely scaric 

 fls. dark violet, very fragrant; outer segments obor
