the Altai mountains ; it grows in dense 

 tufts, and all its parts are covered with 

 silky hairs ; the leaves are about a quarter 

 of an inch long, and made up of three leaf- 

 lets, the central one with three, the lateral 

 ones with two teeth. The stems are ter- 

 minated by one or two little flowers, each 

 with a four-parted calyx border, four 

 petals, and four stamens, or in the females 

 a like number of ovaries. [A. A. BJ 



DRYANDRA. Alarge proteaceousgenus, 

 named after Dr. Jonas Dryander, a cele- 

 brated botanist, who was librarian to Sir 

 Joseph Banks. It is distinguished by 

 having four-parted apetalous flowers, gene- 

 rally clothed on the exterior with reddish- 

 brown wool ; four linear nearly sessile 

 anthers, inserted on the concave extre- 

 mities of the segments of the flower, burst- 

 ing longitudinally ; a round occasionally 

 furrowed style, slightly exserted, and a 

 cylindrical or clavate stigma. The fruit 

 is a woody follicle. The flowers grow in 

 sessile terminal heads, with a closely im- 

 bricated involucre, clothed with dense 

 reddish-brown wool, the outer bracts 

 elliptical, acuminate, the inner ones sub- 

 ulate with a pencil of rufous wool at the 

 point. 



Bryandra, like its congener Banhsia, is 

 more remarkable for the variety and pecu- 

 liar forms of its generally rigid foliage 

 than for the beauty of its flowers. The 

 leaves are either linear or oblong, and with 

 very few exceptions coarsely serrated, 

 lobed or pinnatifid (in B. speciosa they are 

 entire), varying considerably in size, some 

 being from a foot to a foot and a half in 

 length, and not more than a third of an 

 inch in breadth, as B. longifolia, B. Brownii, 

 B. tenuifolia, &c. ; whilst in others, as B. 

 prceniorsa, B. cuneata,B.floribunda, &c.,they 

 are only two inches long, and half an inch 

 broad. The genus has only been found on 

 the south and south-west parts of Australia, 

 the larger number of the species having 

 been discovered in the immediate vici- 

 nity of King George's Sound and Swan 

 River. [R. H.J 



DRYAS. A genus of herbaceous plants 

 with shrubby stems, giving name to the 

 sub-order Bryaclece of the Rosacea;. The 

 species are elegant little evergreen plants 

 of humble growth, with rather large simple 

 leaves which lie prostrate on the ground, 

 and showy white or yellow flowers like the 

 Potentillas and Geums, but well distin- 

 guished from both by having the seed- 

 vessels furnished with a long unjointed 

 feathery appendage or tail. They are 

 found either in high latitudes, or in Alpine 

 or sub-Alpine regions, in both hemispheres. 

 B.octopetala, the only British species, well 

 marked by its eight white petals, is not 

 unfrequent in the mountainous parts of 

 England, Ireland, and Scotland, the last 

 especially. French, Briade: German, Sil-

DRYMARIA. A genus of Illecebracece 

 allied to Spergula, and like it rather to be 

 referred to a section of Caryovhyllaceai. It 



consists of tropical or sub-tropical herbs 

 with slender diffuse stems often rooting 

 at the joints, opposite leaves varying from 

 subrotund to linear, often with small ca- 

 ducous stipules, and white flowers in pani- 

 culate or corymbose cymes. [J. T. S.] 



DRYMODA -picta. The name of a 

 curious minute epiphytal orchid, with pseu- 

 dobulbs, and apparently no leaves, found 

 growing in Birmah, and described and 

 figured by Dr. Lindley in the Sertum Orchi- 

 daeeum, t. 8. The flower is single, on the 

 end of a short scape, and inverted, that is' 

 the labellum is uppermost. 'The column 

 with, its two long petal-like arms is under- 

 most, and the long foot of the column 

 stands over it, bearing at the apex a pair 

 of pink and white lateral sepals, between 

 which hangs down the deep red, fleshy, 

 and hairy labellum.' The other parts of 

 the flower are yellow with brown spots. 

 The four pollen masses without caudicles, 

 attached to a large globose fleshy stig- 

 matic gland, make this plant a link be- 

 tween Epidendrece and Tandem. [A. A. B.] 



DRYMOGLOSSUM. A genus of small 

 creeping polypodiaceous ferns, with simple 

 fronds, belonging to the group T(vvitidea>. 

 The fronds are either of two forms, the 

 fertile ones more or less revolute or con- 

 tracted, or else the fertile apex of the frond 

 is contracted. The soriform thickish lines 

 at or near the margin on the lower surface. 

 The veins are reticulated, and very fre- 

 quently obscure; they are, however, uni- 

 form, and form roundish or oblong-hexa- 

 gonal areoles, which enclose a few free 

 veinlets. The species are nc t very nume- 

 rous, but are widely scattered, occurring 

 in India, China, and Japan, extending to 

 Norfolk Island, and again occurring in 

 the "West Indies. The lines of sori, which 

 are not covered, are sometimes placed 

 directly on the surface of the frond, some- 

 times sunk in a little groove or channel. In 

 some species the sterile fronds are nearly 

 round; in others they are subcordate, or 

 elliptic, or spathulate, while the fertile are 

 twice their length, and of alinear or linear- 

 oblong outline. The common typical spe- 

 cies is B.plloselloides, awide-spread eastern 

 plant. [T. M.] 



DRYMONIA. A genus of South Ameri- 

 can shrubs, belonging to the Gesneractce. 

 They are twiners upon trees in moist 

 places, throwing out rootlets from any 

 part of the stem, and they have opposite 

 serrated petiolate leaves, and large flowers 

 on solitary axillary peduncles, the corolla 

 being campanulate-ringent, gibbous at the 

 base on the posterior side, and with the up- 

 per lip two-lobed and the lower three-lobed. 

 The four included didynamous stamens 

 are inserted at the base of the corolla tube, 

 without any trace of a fifth. Seven species 

 have been described. [W. C] 



DRYMOPHILA. A genus of Liliacem 

 from Tasmania, consisting of herbs with 

 erect stems leafless below, but with two- 

 ranked narrowly-lanceolate sessile acute
