 in lax leafy cymes. Ca/yx 5-partite. Petofe 5, free, yellow. Stamens 10. Hypo- 

 gynous glands 3, linear. Carpels 3, connate to the middle ; ovules several in

Glabrous. Stems 4-10 in. long. Leaves ^-1 J in. long, entire, narrowly obovate. 

 Flowers subsessUe. Sepals very small. Seed ellipsoid, somewhat obovoid, hispid 

 with elongate papiUee. 



This plant by the characters of its carpels and seeds is very closely allied to Se- 

 dum perpu^llvm H. f. ^ T. H. f.^T.m, Joum. Linn. Soc. ii. 90 characterise 

 Triactina as having polyspermous follicles ; the material collected by Sir J. D. Hooker 

 was scanty, and the subsequent collections of C. B. Clarke have all the follicles 

 1-seeded. 



Obbeb LIV. DROSERACEA:. (By C. B. Clarke, F.L.S.) 



Herbs ; catching insects by means of glandular sticky hairs, or by means 

 of petioled leaves with automatically closing laminae. Flowers hermaphrodite, 

 regular. Calyx 4-5- (rarely -8-)partite, or sepals free imbricate persistent. 

 Petals and stamens as many as the sepals, hypogynous or nearly so. Ovary 

 nearly free, globose or ovoid, 1-3-celled ; styles 6-8, capitate fimbriate or bifid ; 

 ovules numerous, on parietal placentse equal in number to the styles. Capsule 

 membranous 5-3-valved, many-seeded. Seeds with fleshy albumen ; embryo 

 cylindric or minute. — Disteib. Species 110, spread over nearly all temperate 

 and tropical lands except the islands of the Pacific.
