style-arras J in. ; crests large, deltoid, acute. Capsule exactly as in I. nepalensis, of 

 which this may be a variety, but the sepals are strongly bearded. 



11. X. Duthieil, Foster in Gard. Ghron. 1887, i. 611; dwarf, leaves 

 linear, flower-heads solitary, spathes 1-fld., perianth-tube very long, blade 

 o£ spreading sepals cimeate-obovate gradually narrowing into the bearded 

 claw, petals oblong obovate red lilac. 



WbstbenHimalata; Kumaon, DutJiie {Sort. Foster). 

 Seems to differ from /. Teumaoneusis, of which it is probably a variety, in the 

 reddish lilao flowers, with darker veins. Capsule IJ by 1 in., trigonous. As in 

 kumaonensis the flowering precedes the mature leafing. 



12. I. Kookeriana, Foster in Gard. Chron. 1887, i. 611; dwarf, 

 leaves linear, flower-head solitary, spathes three 2-fld., persistent perianth- 

 tube short, blade of sepals obovate-ouneate gradually narrowing into the 

 thickly bearded claw, blade of erect petals narrowly obovate, capsule 

 small trigonous beaked. 



Westbbn Himalaya; Labul (flbrf. Foster). 



Stem 5-6 in., sheaths torn. Leaves immature at the flowering season, at length 

 24 by J-| in., pale green. Spathes about 5 in. long j valves lanceolate, ventricoae. 

 Perianth-tube ^ in., limb 1^2 in.; blade of sepals cuneate-obovate, j in. broad, 

 purplish blue blotched with darker ; claw white with violet veins, hairs of beard 

 white yellow-tipped ; blade of petals \ in. broad, suddenly narrowed into the chan- 

 nelled claw ; style-arms very convex dorsally, crests revolute deltoid, coarsely ser- 

 rulate. Capsule oblong. 



tt Stem 1 ft. or more. 



13. X. Clarkei, Baker mss. ; stem tall stout, leaves linear or ensiform 

 strongly striate, flower-heads 1-2, spathes 1-2-fld., valves green to the 

 tips, pedicels nearly equalling the spathe, perianth-tube short infundibular, 

 blade of sepals oblong-cuneate with a bearded erect claw, blade of petals 

 small oblong, claw long, capsule oblong obtuse at both ends. 



SiEKiM HiMAiATA, alt. 10-11,500 ft., J. D. H., Clarke. 



Bootstock very stout, creeping, sheaths long, fibrous. Stem 10-24 in., fruiting 

 very stout, 2-leaved. Leaves not membranous at the tips, at length 1^-2 ft. by 

 ^-i in. Spathes 2^3 in., valves lanceolate, persistent. Perianth bright lilac 

 blotched with violet, throat yellow; tube J in. ; limb 2 in. ; blade of sepals f in. 

 broad, style-arms 1 in. long, bright lilac, crests square. Capsule 1^2 in., oblong, 

 trigonous, valves thick, rigid, keeled at the back. — The leaves are very variable, 

 linear and ^ in, broad in small fld. specimens. 



EOUBII'trL SPECIES. 



Of the following, except I. longifolia, all are supposed to be either garden plants 

 or originally garden escapes, and probably identical with Persian species. The 

 attention of Indian botanists should be given to them. 



I. DEFLEXA, Knowles and Westc. Plor. Cab. ii. 19, t. 57 (Zindl. Bot. Meg. 1840, 

 Misc. 25, 34; Baker in Gard. Chron. 1876, ii. 774 (in part). I. germanica, var. 

 nepalensis, Herb, in Bot. Meg. 1. c. 34. Baker, who characterizes the plant of 

 the Floral Cabinet by the scarious tips of the spathes and deflexed stem, considers it to 

 be intermediate between germa/nica and pallida, but as he has included under it the 

 nepalensis of Koyle & Wallich, some of which are certainly different, his view is 

 perhaps not correct. Herbert, who cultivated authentic specimens, says that the 

 deflexed stem was due to its being grown in heat, and that it is a var. of germanioa, 

 and is I. nepalensis, Wall, in Bot. Reg. t. 818. 



I, KASHMiBiANA, Baker in Gard. Chron. 1877, ii. 744 (Kashmir to Kumaon). 

 Differs, according to Baker, from /. fiorenUna, in the sweet-scented pure white 

 flowers with the spathe-valves scarious at the tips only, and the pure milk white 

 stigmas two-thirds as long as the perianth with large crests.
