whence the nnexpanded flower has a remarkably' navrow form with a heated tip; in 

 this respect it agrees with I. stenantha, which differs in the deoiduouB bracts. The 

 wing-lobes vary much in breadth, and in var. 2 the terminal-lol?es are inflexed, 

 crossing one another ; in var. 1 the form of the wing-lobes cannot be determined ; sti- 

 pular glands sessile or pedioelled or

Temperate Western Himalaya ; Simla, alt. 6-10,000 ft., Elgeworth, Thomson. 



A tall slender pale succulent plant, with difficulty distinguished in a dry state from 

 I. laxiflora, except by the smaller flowers and straighter spur. Leaves 3-4 in., very 

 rarely opposite, flaccid, with often 2 glands at . the base of the blade, crenatures with 

 basal bristles, upper subsessile ; stipulaf gland stipitate. Peduncles Xon^er or shorter 

 than the leaves ; racemes many-flowered ; pedicels J-1 in., capillary, blowers white ; 

 standard with yellow and' red spots. Oapsvie horizontal, J-f in., linear, apioulate, gla- 

 brous. Seeds oblong, rugulose. — I can find no 'valid characters in the description given 

 whereby to separate I. elata ; both are probably forms of J. hrachyoentra, to which 

 Edgeworth's var. /3 of J. micranthemwm may be referable.

 179; erect, slender, branched, quite glabrous, leaves long-petioled 

 elliptic acuminate crenate-serrate, peduncles fascicled at the top of the 

 stem stout erect, racemes many -flowered, bracts minute persistent, flowers 

 minute pale, sepals ovate obtuse concave, standard broadly obovate, wings 

 rather long, lateral lobes rounded, terminal produced 2-lobed, lip boat-

Western temperate Himalaya, alt. 7-10,000 ft., from Kunawuk, Jacquemont, to 

 Maeri, Fleming. — Distetb. Soongaria. 



Annual, 1-2 It. Stem usually naked below, not winged. Leaves 2-5 in., very mem- 

 branous, teeth tipped with a bristle, nerves many, very slender; pstiule J-l in., slender, 

 often with 2 sessile or stipitate stipular glands. Peduncles usually very numerous, 1-3 

 in., very slender, mostly subterminal, with a few reduced lateral ones in the lower axils ; 

 bracts setaceous ; pedicels capillary. Flowers \ in., whitish ; sepals large for the size of 

 the flower ; standard not keeled or spurred. Capsule J-| in., narrow clavate, acute, 

 membranous, glabrous. Seeds few, oblong, pyrilbrm, compressed, rugulose. The bristles 

 of the teeth of this species are distinctly apical. — I. olata, Edgew. ( Trans. Linn. Soc. xx. 

 41) differs according to the description in the distinct spur, in being dotted with black 

 glands, and having glandular tips to the pedicels. (See under L micranthemum.)

 quite glabrous, leaves small shortly petioled elliptic-ovate or lanceolate
