L flavescens (yellowish).* fl. lemon-yellow; limb about 2in. 

 deep ; falls obovate-cuneate, about IJin. broad, reflexing half-way 

 down ; claw veined with purplish-brown ; beard orange-yellow ; 

 standards erect, obovate, rather shorter and broader than the 

 falls ; clusters terminal, three or four-flowered. May. I. few, 

 tufted, ensiform, 1ft. to IJft. long. Stem 2ft. to 3ft. high, 

 glaucous, branched about half-way down. Eastern Europe and 

 Western Asia, 1818. (S. B. F. G. ser. ii. 56 ; B. B. 1845, 35, under 

 name of I. imbricata.) 



I. fiorentlna (Florentine).* fl. fragrant ; limb 3in. to 3iin. deep ; 

 both rows of segments eighteen to twenty-one lines broad ; falls 

 obovate-cuneate, white, tinged with lavender, reflexing half-way 

 down ; claw veined with green and brown ; beard bright yellow ; 

 standards erect, obovate-oblong, with a short claw, pure white. 

 May. I. few, tufted, ensiform, glaucous. Stems 2ft. to 3ft. high, 

 branched above the middle, bearing three or four terminal 

 spathes. South Europe, 1596. The rhizome of this possesses 

 cathartic and emetic properties ; it is also used as the basis of 

 many perfumery powders. (B. M. 671 ; B. M. PI. 273.) 



1. fcetidissima (very totid).* Stinking Gladwin. fl., limb bluish- 

 lilac, 2in. deep ; falls obovate-unguiculate, the oblong-obtuse 

 lamina 3in. broad ; standards erect, oblanceolate, three to four 

 lines broad, shorter than the falls ; clusters sessile, lateral. June. 

 I. ensiform, same length as stem, firm. Stem compressed, 2ft. to 

 3ft. high. West Europe (Britain). A very desirable species, 

 of easy cultivation in almost any situation, but it prefers and 

 flourishes best in a moist one. Its large, thrice-divided seed 

 pods, showing the large, orange-coloured seeds, are very orna- 

 mental. (Sy. En. B. 1494.)

 pblong-unguiculate, Jin. to lin.Tjroad, obtusely rounded at the 

 top, deeply emarginate, gradually narrowed into a claw not 

 more than Jm. long, velvety on the face, with reddish-brown 

 pubescence on the keel ; standards shorter, oblanceolate-spathu- 

 late, IJin. long, Jin. to fin. broad. June. 1. narrow-ensiform 

 briht green. Stems 2ft. to 3ft. high, forked low down, angular 



at tie forks with larg4 i ^ s - 



bright purple, reflexing half-way down ; claw white with brownish 

 veins ; beard bright yellow ; standards obovate-unguiculate deep 

 lilac, erect ; clusters four or five-flowered. May. I tufted few 

 ensiform, very glaucous. Stem 2ft. to 3ft. high, glaucous, forked 

 half-way down. Central and South Europe. A fine ornamental 

 species, and one of the commonest in cultivation ; it has numerous 

 very elegant varieties See Fig. 325. (B. M. 670 B. B. 818, under 

 name of /. nepalensis). 



I. gigantea (gigantic). A garden name of I. ochroleuea.

 white ground ; standards erect, purple, Jin. broad ; clusters 

 terminal, two or three-flowered. May. I. about four tufted 

 linear much overtopping the flowers. Stem solid, ancipitous! 

 about 9m. high. Central and Southern Europe, 1597. (B. M. 681.) 



FIG. 326. IRIS GULDENSTADTIANA. 



I. Guldenstadtiana (Guldenstadt's).* fl., limb 2in. deep ; claws 

 of the falls much longer than the obovate deflexed lamina, which 

 is pure white, jin. broad, with an orange throat; standards 

 oblanceolate, 4-in. broad, erect, rather shorter than the falls, pure 

 white, with a yellow keel and border ; spathes two or three- 

 flowered. June. I. firm, ensiform. Stems stout, 2ft. high. 

 Siberia, 1757. This species is, according to Mr. Baker, the 

 erratica and WiUmaniana of many gardens. SYNS. /. halophila 

 (of Pallas, but not of B. M. 875, which is /. spuria notha), 

 I. stenogyne. See Fig. 326. 



I. halophila (salt-loving). A synonym of I. Guldenstadtiana. 



I. hexagona (hexagonal), fl., tube funnel-shaped, iin. to lin. 

 long, pale or deep lilac, Sin. to 3iin. deep ; falls obovate- 

 unguiculate, the lamina exceeding the claw, lin. to liin. broad ; 

 standards erect, oblanceolate - spathulate, iin. broad, rather 

 shorter than the falls ; spathe valves often 5in. to 6in. long 

 April. I, basal ones ensiform, 2ft. to 3ft. long, by lin. to liin. 

 broad. Stems 3ft. to 4ft. high, deeply forked, and furnished with 

 several large leaves. Southern United States. (B. M. 6787.)
