 Meeds few, youns: obovoid acute at the hilum, opaque. Most nearly allied to /. urtici- 

 folia, Wall., differing in the acute small serratures _ of the leaves, short peduncles, 

 caducous broad bracts, and the curious concave boat-like spurless lip.

A tall, leafy, much-branched annual ; stem stout, succulent. Leaves 3-6 in., mem- 

 branous, with sometimes a few scattered hairs on the upper surface, crenate, bristles 

 or basal; petiole 1-3 in., often with prominent basal stipular glands. Peduncles 

 2-4 in.,'rather stout, erect ; racemes many-flowered ; bracts whorled, ovate, with long 

 prominent glandular tips; pedicels f-1 in., slender. Flowers f-1 in. long from tip of 

 lip to that of standard ; buds 2 -horned by the spur and projecting glandular herbaceous 

 end of the lip, which is large, broad, and remarkably incurved ; wings with small 

 literal lobes and narrow terminal ones. Capsule (according to Wallich) 1^ in., cylin- 

 dric, smooth, shining. Seeds 8-10, subcylindric. Under Wallich's 4729 (/. longi- 

 cornu) there is a fine specimen of this, together with one of /. sulcata, and anotber of 

 /. amphorata ? to neither of which does his character of the double-horned bud apply ; 

 and as the said fine specimen accords with another called /. bicornuta, but without a 

 Catalogue number, in Wallich's Herbarium, collected in Nipal in 1821, and with his 

 description of that plant in Roxburgh's Flora Indica, I retain the name here. The 

 specimen in his Herbarium bearing the Catalogue name of /. bicornuta, has the spur 

 rather more like that of /. amphorata, but it has not the broad sepals. The name 

 longicornu in his Herbarium is inapplicable to any of the 3 plants in the sheet to 

 which it is attached, and had best be suppressed ; and all the more because it is not 

 his own /. longicornu published in Roxburgh (which is De Candolle's, and his own 

 leptoceras). 



108. I. amphorata, Edgew. in Trans. Linn. Soc. xx. 39; erect, branched, 

 slender or robust, glabrous, leaves petioled elliptic acuminate-crenate with 

 glandular stipules, racemes subterminal subumbellately interrupted, bracts 

 broad persistent, flowers large, sepals small broadly cordate, standard orbi- 

 cular dorsally keeled or crested, wings with short lobes, lip a large deep 

 broad rarely conical obtuse sac with a short abrupt incurved spur, capsule 

 linear.

The habit and foliage of this are quite those of /. Hcornuta, but the petioles are more 

 constantly 2-glandular at the base, with the glands either sessile or stipitate, the apex 

 of the leaf is not so produced into an entire linear tail, the raceme is often hardly 

 whorled or interrupted, the sepals are constantly cordate, and the lip is usually of a 

 very different shape, being very large, subcylind'ric and saccate, rarely conoidal, and 

 though at times apiculate, never having the strong callous green points which suggest 

 the name of bicornuta for that plant. The flowers are, 1 believe, rose-coloured and 

 yellow, with red veins ; the lip, often in., is in one specimen from Simla, drawn out 

 into a spur circinnate at the tip, and with the spur considerably over an inch long. 

 The capsule is erect, f-lf in., linear, acuminate, not at all clavate. Seeds few, large,
