3484. SO'LLY^ 



linearis Lindl. navrow-leaved 3^ i | or 5 s.n B Swan River 1839. C l.s.p Bot. reg. 



The present species differs from S, heterophjlla in the intense blue, large 

 size, and great abundance of its flowers, and in its " exceedingly narrow leaves, 

 which have no appearance of having been ever serrated." It is also "a more 

 slender-looking plant." It was found in the Swan River Colony by Drum- 

 mond and others, and was introduced by Robert Mangles, Esq., of Sunning 

 Hill. Cuttings root slowly. Under this head, Dr. Lindley mentions that the 

 plant called Sollya angustifolia, the Billardiera fusiformis of Labillardiere, 

 proves to be a very slight variety of S. heterophylla, having nothing to distin- 

 ■ guish it from that plant but " a few long hairs on the young twigs, and on the 

 back of some of the leaves, of which there is a trace on the younger leaves of 

 S. heterophylla itself." (Bot. Beg., Jan.)

+macrochlla Lindl. long-lipped O or 8 jl.au Pk India 1839. S co Bot. reg. 1840, 8, 



A tall, and rather weedy-growing plant, with very large pink flowers. A 

 native of the North of India, and requiring no other care than sowing in the 

 open ground. (Bot. Beg., Feb.) 



H-tricornis Lindl. three-horned O or 6 jn.au Y India 1839. S co Bot. reg. 1840, 9. 



A very beautiful yellow-flowered species, which derives its name of three- 

 horned from the shape of the flowers. Under this head. Dr. Lindley re- 

 marks, that the I. picta of the Floral Cabinet (see p. 19.) is the 1. longicornu 

 of Dr. Wallich. A very interesting quotation is given from a paper on the 

 genus Impatiens, written by Dr. Wight, which appeared in the Madras 

 Journal for January, 1837 ; by which it appears, that " at least a hundred 

 species occur in those districts, from which Roxburgh described only three." 

 Many of these grow in situations having a mean summer temperature, " not 

 exceeding 70°, if so much." Dr. Wight mentions one circumstance which, " in 

 a physiological point of view, is exceedingly curious. It is, that most of the
