2. Oblong Sundew. Drosera longifolia, Linn. (Fig. 389.) 

 (Eng. Bot. n. 868 in the text, 867 on the plate.) 



Distinguished from the common S. by 

 the leaves much more erect, not half so 

 broad as long and gradually tapering 

 into the footstalk ; the flowering stem is 

 also usually shorter, and not so slender ; 

 the styles less deeply divided, and the 

 seeds are ovoid or oblong ; the testa 

 either close to the albumen, and taking 

 its form, or very slightly prolonged at 

 each end. 



In bogs, with the common S., but 

 much less generally distributed both on 

 the continent of Europe and in Britain. 

 Fl, summer and early autumn.

3. English Sundew. Drosera anglica, Huds. (Fig. 390.) 

 (Eng. Bot. t. 869.) 



Very like the oblong S., but the leaves 

 are still longer and narrower, often an 

 iuch long without the stalk, the flowers 

 and capsule larger, and the testa of the 

 seed is loose and elongated, as in the 

 common S., but more obtuse at the ends. 



In bogs, apparently spread over the 

 same geographical range as the two other 

 species, but being often confounded with 

 the oblong S., of which it may be a mere 

 variety, its precise stations are not very 

 clearly defined. In Britain, more fre- 

 quent in Scotland and Ireland than in 

 England. Fl. summer and early autumn.
