broad; inner segms. oblong, narrower. Hungary, N. E. 

 Asia and Altai region to Mongolia. B.R. 549. G.C. 

 III. 29:337. /. arenaria is the Hungarian representa- 

 tive of I. flavissima. It is smaller than 7. flavissima, 

 but otherwise scarcely distinct. Var. Bloudowii, 

 Ledeb. (7. Bloudowii, Ledeb.). More robust with 

 broader Ivs., a longer st. and larger fls. Gt. 29:1020. 

 Turkestan, Siberia and China. Var. minor, Hort. 

 Smaller. 



12. mandshurica, Maxim. Lvs. from a short creep- 

 ing rhizome whose sheaths are not split into fibers, 

 ensiform, 6-8 in. long, ^in. broad: st. 1-headed: spathe 

 2-fld.; valves 1K-2 in. long, membranous, green with a 

 ecarious edge: pedicel short: fls. yellow; tube M m - 

 long; outer segms. 1^-2 in. long, Kin- broad, obovate- 

 cuneate, truncate, with a yellow beard; inner segms. 

 narrower and shorter; crests of style-branches obtuse, 

 dentate. S. Manchuria. Near /. flavissima, from 

 which it is distinguished by the more compact rhizome 

 and wider Ivs. 



13. Cengialti, Ambrosi. Lvs. ensiform, yellowish 

 green, glaucous, 6 in. long, Y^- broad: sis. 6-12 in. 

 long, usually exceeding the Ivs., 1-3-headed: spathes 

 2-fld., 1 in. long, brown-scarious in the bud but not 

 silvery white like those of /. pallida: fls. bright lilac; 

 outer segms. obovate-cuneate, veined with brown- 

 purple on the pale claw, with a beard of white orange- 

 tipped hairs; inner segms. obovate, short-clawed. 

 Lombardy, S. Tyrol. A dwarf species closely allied to 

 /. pallida. 



,14. aphylla, Linn. (/. bohemica, Schmidt. /. 

 hungdrica, Waldst. & Kit. I.furcdta, Bieb. 7. falcata, 

 Tausch. I. Fieberi, Siedl. 7. nudicaiilis, Hook. 7. 

 benacensis, Kerner). Lvs. glaucescent, 6-12 in. long: 

 st. equaling the Ivs., sometimes forked low down, leaf- 

 less: spathe- valves greenish, tinged with purple: fls. 

 dark hlac; outer segms. obovate-cuneate, 22^ in. 

 long; beard white; inner segms. broader, obovate. E. 

 Eu. B. M. 2361, 5806. B.R. 801. L.B.C. 20:1970. 

 The plant commonly cult, as 7. gracilis is probably 

 7. aphylla. 



15. variegata, Linn. Lvs. 1-1 J^ ft. long: st. equal- 

 ing the Ivs. : outer segms. oblong-cuneate, claret-brown 

 toward the tip, much veined with brown on a yellow 

 ground; beard bright yellow; inner segms. erect, oblong, 

 bright yellow, veined. Austria, Turkey and S. Russia. 

 Long in cult. B.M. 16. Gn. 14:12; 52:364 (var. 

 aurea). G.M. 54:126. Var. honordbilis, Hort. Yellow, 

 shaded with brown. 



16. Idrida, Soland. Lvs. 1 ft. long, slightly glaucous: 

 st. not much overtopping the Ivs., 3-4-headed: spathe- 

 valves green flushed with purple, scarious above, very 

 ventricose, not keeled: outer segms. obovate-cuneate, 

 reflexed from half-way down, dead purple at the top, 

 veined with dull purple on a yellowish ground below; 

 beard yellow; inner segms. broader, dull purple. S. E. 

 Eu. B.M. 986, also B.M. 669, which is probably a 

 different plant. 



17. K6chii, Kerner. Lvs. 12-15 in. long, glaucescent: 

 st. as long as the Ivs., 3-4-headed: spathe- valves 

 lanceolate, the outer herbaceous; the inner partly 

 scarious, tinged with purple along the edge: outer 

 segms. obovate, with a broad cuneate claw, 3)^-4 in. 

 long, 1% in. broad, dark violet; claw veined with brown; 

 beard yellow; inner segms. broadly obovate, clawed, 

 dark violet, somewhat lighter than the outer. Istria, 

 near Trieste and Rovigno. Probably a form of 7. 

 germanica or a hybrid between that species and 7. 

 aphylla. 



18. atroviolacea, Lange. Lvs. very glaucous, 1 ft. 

 long: st. equaling the Ivs.: spathe entirely scarious: 

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

 cuneate, 3 in. long; beard white, tipped with yellow; 



inner segms. as long, 2 in. broad, orbicular. Late May. 

 Known only in cult. Probably either 7. germanica var. 

 atropurpurea or 7. Kochii. 



19. pallida, Lam. (7. asidtica, Stapf. 7. sicula, Tod.). 

 Lvs. 1-2 ft. long: st. much exceeding the Ivs., 2-3 ft. 

 high: spathe- valves wholly scarious before the fls. 

 expand: fls. fragrant, violet, rarely white; outer segms. 

 obovate-cuneate, 3^2 in. long; inner segms. orbicular. 

 Crete, Rhodes, Syria, Palestine. B.M. 685. Gn. 33:32; 

 50, p. 119. G.M. 38:441. G. 29:179. G.L. 23:147. 

 J.H. III. 54:437 (var. delicata). R.B. 30:145 (variety 

 with variegated Ivs.). The spathe -valves entirely 

 scarious even in the bud, the more complicated infl. 

 and the fragrant fls. distinguish this species from 

 7. germanica. Var. dalmatica, Hort. Lvs. 2 in. wide, 

 broader than those of the type, very glaucous: st. 

 shorter and stouter than that of the type: fls. lilac-pur- 

 ple. The finest form of 7. pallida. J.H. III. 56:545. 

 Var. speciosa, Hort. Tall, with large, light blue fls. 



20. plicata, Lam. (7. aphylla, Hort., not Linn. 7. 

 aphylla var. plicata, Ker). Rhizome, st. and lys. as 

 in 7. pallida: outer segms. obovate, pure white in the 

 center, conspicuously veined with lilac toward the 

 margin and on the claw; inner segms. very plicate, 

 white tinged with lilac on the margin. B.M. 870. 

 Known only in cult. Probably derived from 7. pallida. 



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

 Much dwarfer than 7. florentina and 7. pallida. St. 

 1-1 J^ ft. long: spathe- valves flushed with violet: outer 

 segms. 2-2 ^ in. long, obovate-cuneate, white, faintly 

 veined and flushed with purple on the margin; inner 

 segms. as large, much crisped, pure white, except the 

 purple keel and margin. Fragrant. Known only in 

 cult. 



22. imbricata, Lindl. (7. flavescens, Sweet. 7. 

 obtusifolia, Baker). Lvs. about 6 in a tuft, broadly ensi- 

 form, pale green, 6-;8 in. long at flowering time: st. 

 12-20 in. long, bearing a terminal and several nearly 

 sessile lateral clusters each subtended by a ventricose 

 navicular bract: spathe-valves oblong navicular, 2-3 

 in. long, green, membranous, very ventricose: fls. 



1967. Iris pumila. One of the best dwarf species 

 No. 6. 



greenish yellow; tube 1 in. long; outer segms. obovate- 

 cuneate, 2 in. long and 1 in. broad, veined with brown 

 on the claw; inner segms. erect, rounded oblong, sub- 

 cordately unguiculate, mottled with brown on the claw. 

 Transcaucasia and N. Persia. B.R. 31:35. B.M. 7701. 

 Confused with 7. flavescens, from which it differs by 

 the membranous inflated green spathe-valves.

 high, bearing 3-4 heads: spathes 2-3-fld., not entirely
