IRIS

 stalks. Var. variegata, Hort. Lvs. striped with creamy 

 white. Var. pallida, Hort. Fls. pale sulfur-yellow. 



74. versicolor, Linn. (7. virginica, Linn.). Fig. 

 1972. Lvs. slightly glaucous, 1^-2 ft. long: st. forked 

 low down and often branched above, 2-3-headed : tube 

 very short; limb violet-blue; outer segms. spatulate,

 England 1732. B.M. 21, 703.

 simple, 3 ft. long, 2-3-headed, with several large Ivs., 

 the upper ones exceeding the fls. : spathe-valves some- 

 times If .-like: tube 1 in. long, green, dilated upward;

76. caroliniana, Wats. Fig. 1973. Lvs. 2-3 ft. long, 

 bright green: st. stout, simple or branched: tube >in. 

 long; limb lilac, variegated with purple and brown;

 Differs from /. versicolor by its green Ivs. Discovered by 

 W. A. Manda in N. C. B.M. 8465. G.F. 6:335 

 (adapted in Fig. 1973). 



77. setdsa, Pall. (7. brachycuspis, Fisch. 7. 

 tripetala, Hook.). Lvs. thin, green, 1-1^ ft. long: 

 st. deeply forked, much exceeding the Ivs.: tube J^in.

 Siberia, Japan, and N. W. Amer. to Labrador and 

 Maine. B.M. 2326; 2886. Gt. 322. 



78. Monnieri, DC. Lvs. slightly glaucous, 2-3 ft.' 

 long: st. stout, terete, 3-4 ft. long, with several sessile 



clusters of fls 



1973. iris caroliniana. ( x H) 



long, lemon-yellow, with- 

 out veins; blade of 

 outer segms. orbic- 

 ular, 1-1 y z in. 

 long, equaling the 

 claw; inner segms. 

 oblong - u n g u i c - 

 ulate, 1 in. broad. 

 Origin not cer- 

 tainly known. 

 Found in the gar- 

 den of Lemonnier 

 at Versailles. G. 

 25:389. Not 

 showy except in 

 masses. This and 

 7. orientalis and 7. 

 aurea are very 

 closely related and 

 together with 7. 

 halophila are per- 

 haps all forms of 

 7. spuria. I. Mon- 

 nieri is uniformly 

 bright lemon-yel- 

 low, free from 

 veins or spots. By 

 its coloring, it dif- 

 fers from 7. orien- 

 talis and by the or- 

 bicular bladeof the 

 outer segms. from 

 7. aurea, in which 

 the blades are 

 oblong. Often at- 

 tributed to Crete. 



79. hal6phila, Pall. (7. Gueldenstxdtiana, Lepech.). 

 Lvs. pale green, 1-1 ^ ft. long: st. stout, terete, lj- 

 2 ft. long, often bearing 1-2 spicate clusters below the 

 end one: limb pale yellow; outer segms. with an orbicu- 

 lar blade H-Min. broad, shorter than the claw, which 

 has a bright yellow keel and faint lilac veins; inner 

 segms. shorter, erect.

80. orientalis, Mill. 

 (7. ochroleiica, Linn. 7. 

 gigantea, Carr.). Fig. 

 1974. Plants growing 

 in strong clumps: Ivs. 

 2-3 ft. long, 1 in. or 

 more broad, slightly 

 glaucous: st. 3 ft., 

 stout, terete, about as 

 long as the Ivs., with 

 2-3 spicate clusters of 

 fls.: outer segms. ob- 

 ovate, 1 in. broad, as 

 long as the claw, yel- 

 low, paler or white 

 toward the margin; 



inner segms. oblong, 1 1974. Habit sketch of Iris orientalis.

low to whitish. Asia 



Minor and Syria. B.M. 61. Gn. 20:272; 38:462; 46, 

 p. 362; 50, p. 186; 69, p. 25; 72, p. 622. Gn. M. 15:360. 

 R.H. 1875, p. 357. One of the largest of the irises. 

 Grows in almost any situation. White forms of this 

 plant are in cult, but no purple forms are known. See 

 note under 7. Monnieri. 



81. aurea, Lindl. Lvs. scarcely glaucous, 1^-2 ft. 

 long: st. 3-3 J^ ft. long, stout, terete, with 1-2 sessile 

 lateral clusters below the end one: spathes 2-3-fld.: 

 pedicel long: limb bright yellow; outer segms. with an 

 oblong undulate blade 1 in. broad, as long as the claw; 

 inner segms. less than >in. broad, with much-waved 

 edges. July. W. Himalayas. B.R. 33:59. Gn. 31:52. 

 G. 25:388. B.M. 1131 (as 7. spuria var. halophila). 

 Intro, by Dr. Royle. The color is a rich golden yellow, 

 much deeper than that of 7. Monnieri and the others 

 of this group. See 7. Monnieri. Said to grow up to 5 

 ft. high under favorable conditions. Var. intermedia, W. 

 I., in G.C. III. 28:22. Intermediate between 7. aurea 

 and 7. orientalis. Deep yellow, with crisped segms. like 

 7. aurea, but having the obovate outer segms. and narrow 

 inner segms. of 7. orientalis. Fls. late, with 7. aurea. 



82. fcetidissima, Linn. GLAD WIN. Lvs. 1-1 H ft. 

 long: st. compressed, 2-3 ft. long, 2-3-headed : tube %m. 

 long; limb bright lilac; outer segms. 1 3/2-2 in. long, 

 with a suborbicular blade equaling the claw; inner 

 segms. shorter, oblanceolate. Cent, and S. Eu., Eng- 

 land, Afghanistan and Algeria. Gn. 47, p. 30. G. 

 19:543. This plant is very distinct, and is easily 

 recognized by the odor of the broken Ivs. The caps. 

 remain on the plants in winter, bursting open and 

 displaying rows of orange-red berries. The fls. are 

 rather inconspicuous. There is a whitish variety with 

 brown veins, and a variety with white-striped Ivs. A 

 pale yellow form veined with green also occurs occa- 

 sionally. 



83. spuria, Linn. Lvs. firm, linear, glaucescent, 1 ft. 

 long, longer after flowering: st. overtopping the Ivs., 

 bearing 1-3 spicate heads: pedicel shorter than the 

 spathe: tube J^-^in. long; limb bright lilac; outer 

 segms. with an orbicular, spreading blade ^m- broad 

 and half as long as the claw; claws broad, concave, 

 lilac, with a yellow keel and purple veins; inner segms. 

 shorter, straight, oblanceolate; style-crests small. Cent. 

 and S. Eu. B.M. 58. Var. ndtha, Bieb. (7. halophila, 

 Ker). More robust: Ivs. 1 in. broad: spathes larger:
