and afterwards further up the same stream, in similar but more acces- 

 sible places. 



At the date of the publication of my Prodromus, only one species of 

 this unusual form was known, the I. Scapiflora : since then, I have 

 seen three or four more, namely, the two here described, and one or 

 two, I am uncertain which, in Ceylon. 



§ 6. Leaves opposite, pedicels one flowered. 

 15. Impatiens fasciculata ? 



Herbaceous, erect, sparingly ramous at the base, glabrous, except the 

 upper surface of the leaves, which is hispid. Leaves opposite, linear or 

 lauceolate subsessile, cordate at the base, acutely subspinous, serrated, 

 with two short, reflexed, subulate, interpetiolar stipule-like glands. 

 Pedicels, one or two from each axil, shorter than the leaves, erect in 

 flower, afterwards deflexed, pendulous. Flowers large ; upper sepal 

 broad cordate, keeled, retuse, mucronate ; lower infundibuliform, 

 scarcely half the length of the long linear, curved, slightly bifid, spur. 

 Upper lobes of the petals triangular, pointed, about half the length of 

 the upper sepal, and considerably shorter than the linear, acute, slightly 

 falcate, lateral ones ; lower lobes semiorbicular, notched at the point, 

 3-4 times larger than the upper sepal, but shorter than the spur. 

 Capsule oblong, slightly ventricose. 



This plant certainly differs in some respects from I. fasciculata as 

 now characterized, but not enough, it appears t,o me, to admit of my 

 drawing up a separate character for it, the principal pointsof distinc- 

 tion being in this having two interpetiolar glands, resembling stipules, 

 in the serratures of the leaves, being spinous, and in the lower lobe of 

 the petals being three or four times larger than the upper sepal, in place 

 of only twice, the size according to the character. 



There is yet another source of doubt as to their identity, the one grows 

 on the plains of Malabar, the other on the elevated marshes of the 

 Pulney mountains, nearly 6,000 feet above the sea. If new I would 

 propose the name I. pungens in allusion to the spinous teeth of the leaves. 



16. Impatiens rosmarini folia ? (Retz.) 

 " Pedicels solitary, shorter than the leaves, leaves opposite, linecr : 

 spur short, somewhat recurved at the apex."— De Cand. Prod. Syst. 

 Veget. I. p. 636. 



I have adopted Retz's specific name for this plant with a doubt, which 

 however, I believe unnecessary, as the only difference between the plant 

 here figured and the above character translated from Decandolle's 

 Prodromus, is in the number of pedicels in that being solitary, in this 

 solitary or paired, in my opinion a distinction of no importance. This 

 species appears exactly intermediate between l.filiformis and I. lenella ;
