(an Linn.?), I. flacrJda, tab. 5276 (an Arn. ?), /. hipartita, 

 Arn., and /. lucida, Heyne, all requiring study with better 

 material than has hitherto been available, but I think all 

 distinct. From all these I. cuspidata differs in the 

 snow-white stem and branches, &c., a character which 

 escaped both White and Arnold. 



Impatiens cuspidata is a native of Conoor in the Nilghiri 

 Hills, at about five thousand feet elevation, where it was 

 first found by Wight. It has been in cultivation in 

 England since 1877, when specimens were sent by Messrs. 

 Veitch to the Kew Herbarium. The plant here figured 

 represents a most remarkable state of it, drawn in July, 

 1891, by Miss Smith, in a conservatory of the Royal 

 Botanic Gardens, Edinburgh, in which the base of the 

 stem was nearly an inch in diameter, the lower branches 

 nearly as thick at the base, the upper with the nodes 

 thickened and elongated into cylinders of a pale pinkish 

 white colour, contrasting remarkably with the white inter- 

 nodes, and the upper nodes quite normal. I have given it 

 the varietal name of arthritica, from its gouty appearance ; 

 but am disposed to regard it rather as a diseased condition, 

 well worthy of study by a vegetable anatomist. 



Descr. — A shrub four to five feet high, with spreading 

 branches, covered with a snow-white farina, the lower 

 nodes elongate, and thickened into cylinders of a pale 

 reddish colour. Leaves alternate, or the uppermost oppo- 

 site, three to five inches long, lanceolate or oblong- 

 lanceolate, finely acuminate, serrulate, flaccid, bright green, 

 base acute ; nerves obUque, more or less pilose beneath ; 

 petiole slender, with a few soft, scattered, gland-tipped 

 bristles. Pedimcles solitary or binate, axillary, longer than 

 the petioles, ebracteolate, quite naked, one-flowered. 

 Floioers about an inch broad, very pale red. Sepals two, 

 very small, ovate, narrowed into long, slender points, 

 green. Standard orbicular, two-lobed, erect, with a dorsal 

 horn. Winga two-lobed ; terminal lobe obliquely oblong, 

 apiculate, much larger than the oblong, deflexed basal one. 

 I/ip boat-shaped, acute, abruptly narrowed into a nearly 

 straight, slender spur, about twice as long as the wings. 

 Capsule ovoid, narrowed at both ends. — J. D. II.
