132 PENTANDIIIA — HEXAGYNIA. [Drosera. 



Sir J. E. Smith, are taken from the calyx. In the present the petals 

 are of a paler blue than in the preceding species, and smaller in propor- 

 tion to the size of the calyx. 



4. L. cathch'ticum, L. (^purging Flax) ; leaves opposite oblong, 

 stem dichotomous above, petals acute. E. Bot. t. 382. 



Pastures, everywhere abundant. Fl. June, July. 0. — Stem slender, 

 upright, 2 — 6 inches high. Flowers gracefully drooping before expan- 

 sion, white, small. 



99. SiBBALDiA. Linn. Sibbaldia. 



1. S. proctimbens, L. (procumbent Sibbaldia) ; leaves ternate, 

 leaflets wedge-shaped tridentate. E. Bot. t. 175. 



Near, and upon, the summits of the Highland mountains of Scotland, 

 abundant. Fl. July. 11 . — A small, 'glaucous, slightly hairy plant, woody 

 at the base and roots. Petals small, yellow, sometimes wanting. Stam. 

 5 — 7. Pistils 5 — 8 or 10. — Nearly allied to Potentilla, as Mr W. 

 Wilson well observes. 



PENTANDRIA— HEXAGYNIA. 



100. Drosera. Linn. Sun-dew. 



1. D. rotundifolia, L. (round-leaved Sun-dew) ; leaves radical 

 orbicular spreading, petioles hairy, seeds chaflFy. E. Bot. t. 867. 



Bogs and moist heathy ground, frequent. Fl. July. If. — Leaves, 

 in all our species, covered with red pedunculated viscid glands, which 

 retain insects. Scape 2 — 5 inches high, glabrous. Flowers racemed, 

 secund, small, " each, as it successively occupies the apex of the perpendi- 

 cular part of the scape, expanding, but if the day be not sunny, it never 

 expands at all ; but the next above it does when it arrives at the apex." 

 (J. E. Bowtnan). Stales variable in number. 



2. D. longifolia, L. (spathulate-lcaved Sun-detv) ; leaves radi- 

 cal spathulate very obtuse erect on long glabrous petioles, seeds 

 with a compact rough coat not chaffy. E. Bot. t. 868. 



Bogs and moist heathy ground, not uncommon, but more frequent in 

 the south than in the north. South of Ireland. Fl. July. 7/ . — Well 

 distinguished from the following, by its rough, and not loose, coat to the 

 seeds, a character long ago observed and figured by Heyne Schkuhr and 

 confirmed by Mr W. Wilson. Styles often 8 ; stigmas deeply cloven. 

 Mr W. Wilson detected a curious monstrosity in the flower of this, having 

 " one germen enclosed within another, and a third within the second ; 

 the external one open at the top and fringed with styles and abortive 

 anthers. Rudiments of seeds Hned the inner surface as usual. The 

 inner germen had styles and anthers intermixed, and was closed at the 

 top, the innermost was more imperfectly formed, but with rudiments of 

 styles. There were 8 petals and about 6 perfect stamens in the flower." 

 The same acute Botanist, too, observed that "specimens' gathered in 

 Cheshire abounded in colouring matter and stained the paper in which 



' With me, in the Herbarium, both D. Anglica and D. Zowj/ZfoZ/a retain the 

 property of staining the papers that lie next to them for a great number of 

 years ; so that the form of the leaves, scapes, and flowers is distinctly repre- 

 sented through to tlie backs of the sheets on which they ai'e fastened, and 

 also upon the backs of several others which may have, at different times, 

 lain above them j and this though the specimens are perfectly dry.
