as the petals ; the filaments flat, villous in front, scarcely so lono* as the 

 antlieis. Style subglabrous. Fruit unknown, 

 Singapore] ; Ridley 3972. 



A very distinct species in the neighbourhood of P. vdiitina, Bl., but with 

 narrower leaves, much more fcomentoso flowers and inflorescence, and a wider calyx- 

 tube. 



Note. — I here take the opportunity of describing a very distinct new species 

 from Sumatra. 



PoLYOSMA LONGE-PEDICELLATA, King n. spec. A shrub or tree 15 feet high 5 

 young branches coarsely adpressed-puboscent. Leaves elliptic or obovat-e-elliptic, 

 abruptly and shoi^tly acuminate ; the edges slightly sinuate and very obscurely and 

 liiinutely toothed, slightly recurved when dry ; the base caneate ; upper surface 

 glabrous, finely reticulate ; the lower with short coarse adpressed hairs especially on 

 the midrib, finely reticulate; main nerves 14-16 pairs, almost horizontal, slightly 

 cnrved and interarching towards the edge of the bade, slightly prominent on 

 the lower surface only when dry, the intermediate nerves almost as distinct; the 

 I'eticulations minute, distinct on both surfaces ; length 5'25^7 in., breadth 2*2-3'25 

 in. ; petiole '75-l"25 in., paberalous. Raceme solitary, terminal, rather longer than the 

 leaves, with pubescence like the young branches. Flowers '5 in. long, on slender 

 adpressed-pubescent pedicels 'S-'SS in. long, and bearing three adpressed bracteoles 

 towards their apices. Calyx-tithe '1 in. long, adpressed-pubescent, its teeth broadly 

 triangular. Petals '4i in. long, linear, obtuse, adpressed-pubescent outside. Fruit 

 ovoid, tapering to each end, crowned at the apex by the very short calyx-lobes and 

 by the sharp base of the style, minutely adpressed-pubescent, '5 in. long, and '3 iu. 

 in diam. Fruit pedicels ■5-'7 in. long, sometimes deflexed. 



Eastern Sumatra ; at elevations of 3200 and 3700 feet, Forbes 2037, 2250. 



Order XLI. DROSERACE^. 



Herbs; catching insects by means of glandular viscid 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, hypogy- 

 nous or. nearly so. Ovary nearly free, globose or ovoid, 1-3-celled ; 

 styles 6-3, capitate, fimbriate or bifid; ovules numerous, on parietal 

 placentas equal in number to the styles. Capsule membranous, 5-3- 

 valved, many-seeded. /Seetis with fleshy albumen; embryo cylindric or 

 minute. Distrib. Species 110 ; spread over nearly all temperate and 

 tropical lands except the islands of the Pacific. 



1. Drosera, Linn. 



Perennial herbs, scapigerous or with a leafy stem, gland iilar-pilose. 

 Leaves radical or alternate, usually circinate in vernation ; stipules 0, or 

 scariose and adnate to the petiole. Calyx free from the ovary, 4-8- 

 partite, sepals persistent. Petals 4-8, hypogynous or scarcely peri- 

 gynous, Avhite or rose-coloured, withering, peristent. Stamens as many
