der, about twice the length of the petals, straight. Petals, smaller than 

 the upper sepal, the upper lobe much smaller than the lower. Capsule 

 oblong, attenuated at both ends, glabrous. - 



Hab. Shevagherry hills, in dense forests, at an elevation of about 

 4,500 feet. 



This is a large, very ramous, bushy plant, from four to six feet high, 

 the larger branches naked, but the young terminal shoots bearing 

 numerous, closely congested, rather small leaves, the largest rarely ex- 

 ceeding 2 or 21 inches long in its whole length ; by | broad. Some- 

 times the petiole has only one pair of glands, but oftener more, and the 

 bristles of the lower serratures of the leaves are often glandular. The 

 peduncles are usually three together, and about the length of the 

 adjoining half. The flowers are conspicuous on account of the large 

 upp^r very petaloid sepal, nearly equaling in size both the petals, and 

 the much greater size of the upper than the lower lobes of the petals. 

 It is nearly allied to I. arcuata, but is readily distinguished by being 

 every where glabrous, in place of all more or less clothed with pubes- 

 cence as in that species. It is distinguished from I. Balsaminia by its 

 glabrous capsules, and from Leschenaullii by its glandular petioles, 

 and aggregated pedicels.

(green). 



4.— Impatiens auriculala. (ii. W.) 



Herbaceous, procumbent, glabrous, rooting along the stem. Leaves 

 congested on the. ends of the shoots, petioled, alternate, broadly ovate, 

 lanceolate, bristle serrated. Peduncles about the length of the petioles^ 

 two flowered. Pedicels erect, many times longer than the peduncle. 

 Flowers large. Sepals, upper vaulted, crowned with a foliaceous crest ; 

 lateral ones very large, pendulous, obliquely ovate, acute ; lower, 

 conical, including the inferior half of the lower petals, and ending in a 

 hooked spur. Upper lobes of the petals smaller, opposed to the superior 

 dilated half of the lower. Capsule ovate, many seeded. 



Hab. Courtallum on branches of trees, flowering in August and 

 September. 



This species differs so much in the general form of it", flowers, and 

 in the relative size of their parts, that I at first proposed separating 

 it from the genus. The discovery of a second very nearly allied spe- 

 cies, but agreeing better in these respects with the other members of 

 the genus, renders such a step inadmissible. The specific name is in 

 allusion to the side sepals hanging down on each side like dog's ears. 

 The general appearance of the flower, from the mixture of colours 

 which it presents, is very unusual. The upper sepal or helmet, which, 

 it greatly resembles, both in form and situation, is bright green, the
