 and Kashmir, Jacquemont. 



Stems 1-3 in. Rosulate leaves f in. long; cauline ^ ^ in. somewhat densely 

 imbricate, sessile, oblong or elliptic, glandular-pubescent. Cyme dense. Petals lan- 

 ceolate (white or rose-white ?). Seeds narrowly ellipsoid, minutely striate longitu-

8. TRIACTINA, H.f. $ T. 



A weak succulent herb. Leaves alternate and verticillate. Flowers yellow, 

 in lax leafy cymes. Calyx 5-partite. Petals 5, free, yellow. Stamens 10. Hypo- 

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

 each carpel. Follicles 3, connate to the middle, divaricate above, 1-seeded. 



1. T. verticillata, H.f. $. T. in Journ. Linn. Soc. ii. 103. 



SIKKIM, alt. 10,000-12,000 ft. ; Lachen, J. D. H. ; Tumbok, C. B. Clarke. 



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

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

 with elongate papillae. 



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

 dum perpusittum H. f, $ T. H. f. $ T. in Journ. 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. 



OKDEE LIV. DROSERACEJE. (By 0. 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 5-3, capitate fimbriate or bifid ; 

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

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

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

 and tropical lands except the islands of the Pacific.
