On the Genus Impatiens.

§ 1. Leaves alternate, pedicels solitary or aggregate, one flowered. 

 1. — Impatiens albida. (R. W.) 



Suffruticose, erect, ramoin. Branches terate, marked with numerous 

 scars of fallen leaves. Leaves ovato-lanceolate, pointed, slightly serra- 

 ted, attenuated at the base, tomentose. Pedicels solitary, as long as the 

 leaves, glabrous. Sepals, upper large, broadly emarginate, villous 

 above; lower one tomentose : spur slender, tapering, curved, nearly 

 twice the length of the flower : lateral sepals cordate, acuminated. Pe- 

 tals deeply 2-lobed, the upper lobes larger. Ovary hairy ; ovules few. 



Habitat Courtallum, at an elevation of between 2,500 and 3,000 feef, 

 but rare, growing on clefts of rock in exposed situations. 



This is a very beautiful species, distinguished on account of tho size 

 and beauty of its snow-white flow T ers, which contrast agreeably with 

 the foliage, which has a fine silky appearance, from being thickly 

 clothed with close-pressed white hairs. I gathered it in flower, both 

 in September and February, but on neither occasion found ripe fruit. 

 It appears to be a small shrub, so far as I have yet seen, not exceeding 

 21 to 3 feet in height, with the leaves and flowers congested on the 

 extremities of the branches. 



2. — Impatiens dasysperma. (R.W.) 



Herbaceous, erect, unbranched. Leaves petioled, alternate, ovato- 

 lanceolate, acuminated, hairy above, glabrous beneath, crenato-serra- 

 ted. Petioles glanduliferous. Pedicels axillary, solitary or paired, erect, 

 scarcely half the length of the leaves. Flower rather small. Sepals, up- 

 per obcordate, cuniate, cuspidate ; lateral ones minute, lobes of the petals 

 nearly equal, scarcely half the length of the slender, curved, slightly 

 hairy spur. Capsule glabrous, ovate, many seeded; seeds hairy. 



Hab. Courtallum, in alpine jungles; flowering in August and Septem- 

 ber. 



This species appears nearly allied to I. Leschenaultii, but differs in 

 habit, this being herbaceous and branchless, while that is suffruticose 

 and branched. In this the leaves are hairy, and the petioles glanduli- 

 ferous ; in that glabrous and eglandular ; in this the capsule is many 

 seeded, in that few. 



The name T have adopted is expressive of the hairiness of the seeds. 



3.— Impatiens jloribunda, 

 Suffruticose, erect, ramous, every where glabrous. Leaves alternate, 

 congested near the ends of the branches, on long glanduliferous petioles, 

 lanceolate, acuminated, with incurved bristle serratures, glands of the 

 petioles subulate, hooked at the apex. Peduncles axillary, 2-3 

 together, equalling the leaves. Sepals, upper large, petaloid, two-lobed, 

 with a subulate point between, lateral ones minute subulate. Spur slen-
