X. DROSERACEaE. 
[. Drosera . 
Ord. X. DROSERACEaE Be Cand. 
Sepals usually 5, persistent, equal. Petals as many as the 
sepals. Stamens free, equal in number with the petals or 2 — 4 
times ,as many; anthers dehiscing longitudinally. Ovary 1. 
Styles or sessile stigmas several. Capsule 1-celled, with 
3 — 5 placentas and 3 — 5 valves, loculicidal ; valves bearing 
the seeds along their middle. Seeds never comose. — Herbs 
of marshy ground , with the leaves all rudical or stem-leaves 
alternate. 
1. Drosera. Styles filiform. Leaves clothed with glandular hairs. 
2. Parnassia. Stigmas sessile. Leaves glabrous. 
Sub-Ord. I. DROSEREaE. Styles (or style') elongated. Stamens 
hypogynous, as many as the petals. Capsule 1( — 3 )-celled, 
3 — 5 -valued. Seed with a minute embryo at the base of a co- 
pious fleshy albumen. Leaves clothed with beautiful glandular 
hairs, and having a circinate vernation. 
1. Drosera Linn. Sun-dew. 
Styles 3 — 5, variously divided, usually bipartite and resem- 
bling 6 — 10 distinct, styles. Capsule 1-celled, many-seeded. — 
Name derived from Spotroe, dew, the glands exuding a pellucid 
fluid, which makes this plant appear as if covered with dew. In 
the Latin of the middle ages ( for it was unnoticed by the an- 
cients) it is called Ros solis, a mere translation of the common 
name. Nearly all the species stain the paper in which they 
are placed, of a purple colour. 
1. D. rotund) folia L. ( round-leaved S.); leaves radical ob- 
ovato-orbicular spreading, petioles hairy, seeds chaffy. E. B. 
t. 867. 
Bogs and moist heathy ground, frequent. 2/.. 7, 8. — In all our 
species the leaves are covered with red stalked viscid glands, which 
retain insects ; the flowers are racemed, small, secund, on a scape, 
and the styles (3 — 4) are bipartite. Stiymas entire, clavate. Petals 
almost always 6. 
2. D. longifolia L. (spathulate-leaved S.) ; leaves radical ob- 
long-spatkulate obtuse or obovate on long glabrous erect petioles, 
seeds with a compact rough coat not chaffy. E. B. t. 868. 
Bogs and moist heathy ground, not uncommon ; more frequent in 
the south than in the north. Isle of Skye. South of Ireland. If.. 
7, 8. — Well distinguished from the following, by its rough, and not 
loose, coat adhering firmly to the rest of the seed, a character long ago 
observed and figured by Dreves and Hayne. Petals, sepals, and sta- 
mens often 6 and sometimes 8 in this and the next species. Limb of
