FIG. 683. FLOWERS AND LEAF OF DROSERA FILIFORMIS. 



D. binata (twin-leaved).* /. pure white, large ; raceme dicho- 

 tomous. June to September. I. all radical, on long footstalks, 

 deeply parted with two linear lobes. A. 6in. Australia, 1823. 

 Plant stemless. SYN. D. dichotoma (of gardens). (B. M. 3082.) 

 Perennial. 



1>. capensis (Cape), fl. purple ; scape rather ascending, somewhat 

 hairy, longer than the leaves. June, July. I. sub-radical, oblong- 

 linear, obtuse, tapering at the base ; footstalks glabrous, shorter 



684. DHOsKUA JIOTUNDIFOUA. 



Drosera continued. 



than the limbs of the leaves. A. 6in. Capo of Good Hope, 1875. 

 Perennial. (B. M. 6583.) 



D. dichotoma (dichotomons). A synonym of D. binata. 



D. filiformis (thread-formed).* fl. purple, large ; scapes erect, 

 hardly equal in length to the leaves. June to August. {. filiform, 

 very long, from a bulb-like base or conn ; footstalks woolly at the 

 base, much shorter than the leaves. A. 1ft. North America, 

 1811. See Fig. 683. (B. M. 3540.) Perennial. 



D. Innata (crescent-leaved). /. yellow ; racemes lateral, few- 

 flowered ; sepals ovate, acute, beset with glandular hairs on the 

 margins. July and August. L, radical ones roundish-reniform ; 

 cauhne ones scattered, stalked, moon-shaped, peltate. Stem 

 erect, glabrous. A. 6in. Nepaul. A very beautiful annual plant, 

 rarely seen in cultivation. 



D. panclflora (few-flowered). /. white; scapes beset with 

 glandular hairs, one or two-flowered. July, August. I. ovate- 

 oblong, tapering at the base. A. Sin. Cape of Good Hope, 1821. 

 Perennial. 



D. peltata (peltate).* /. pink, racemose. I. spaced along an 

 elongated stem, forming minute flattened cups with the foot- 

 stalks attached, not to one margin, but to the bottom ; the inner 

 surface and the edges of the cups are studded with tentacles. 

 A. 1ft. Australia. Annual. (G. C. n. s., xix. 436.) There are two 

 varieties of this species : foliosc, with white flowers ; and gracile, 

 with pink. 



D. rotnndifolia (round-leaved).* JL white ; scapes erect, four or 

 five times higher than the leaves. July, August. I. orbicular ; 

 footstalks hairy, longer than the limb. The whole disk of the leaf, 

 but especially its margin, is beset with red inflexed hairs. 

 A. 4in. Northern hemisphere (Britain). Annual. See Fig. 684. 

 Other native species are : anglica and intermedia. 



D. spathnlata (spathulate-leaved).* fl. purple, almost sessile, 

 disposed in short racemes ; scape glandular at the top, as well as 

 the calyces. July. I. oblong-spathulate, tapering somewhat into 

 the footstalk. A. Sin. Australia, 1861. Perennial. (G. C. n. s., 

 xvi. 852.) 



D. Whittakert (Whittaker's). fl. white. Australia, 1862. A very 

 rare species, much resembling D. gpathulata in habit, but more 

 erect. It is a deciduous form, and requires a long rest. Before 

 starting into new growth, it must be taken out of the old soil and 

 repotted. Perennial. 



DROSERACE.2E. An order containing six genera 

 and upwards of a hundred species, closely allied to Saxi- 

 fragece. Perennial and annual glandular herbs, rarely 

 shrubby below. Sepals four to eight, persistent ; petals 

 four to eight ; stamens four to twenty. Leaves variable, 

 radical and rosulate, or cauline and alternate, circinate 

 in bud, stipulate. Most of the species are found inhabiting 

 marshy places. Illustrative genera are : Dioncea, Drosera, 

 and Drosophyllum. 



DROSOPHYLLUM (from drosos, dew, and phyllon, 

 a leaf; in allusion to the leaves being beset with stipi- 

 tate glands, appearing like dew). OBD. Droseracece. A 

 remarkable and very pretty sub - shrubby greenhouse 

 plant, thriving in a light sandy loam. Propagated 

 by seed. It should he kept somewhat dry, and no 

 shading will be needed. 



D. Insitanicum (Portuguese).* /. yellow, large, disposed in a 

 corymb at the top of a leafy stem, which attains 1ft. in height. 

 Summer. I. elongate, linear, attenuated, circinate and revolute 

 in vernation. Stem thick, woody, 2in. to Sin. high, at the top of 

 which are the leaves. Spain, Portugal, and Africa, 1869. This 

 one of the most singular plants of the European flora 

 inhabits sandy shores and dry rocks by the sea and inland. 

 The nature of the glandular hairs is different from that of the 

 Droseras ; their rigid pedicels not being endowed with the motive 

 power of the British and other species of the genus just men- 

 tioned. " A still more anomalous character is to be found in 

 the way the leaves are developed in the bud, being circinate and 

 revolute, not involute, as in our Droseras, in Ferns, Cycads, and 

 other plants ; and of this mode of development Drosophyllum 

 is, in so far as I know, the only example in the vegetable king- 

 dom" (J. D. Hooker). (B. M. 5796.) 



DRUMMONDIA. See Mitella. 



DRUPACEJE. Formerly regarded as a distinct 

 natural order, but now as a section of liosacece. The 

 principal characters relied on to distinguish it reside in 

 the fruit, which is a drupe, with a hard endocarp. 



DRUPE. A succulent or fleshy fruit, consisting of 

 a hard-shelled seed, as in Olive, Plum, and Cherry. 



DRYANDRA (named after Jonas Dryander, a dis- 

 tinguished Swedish botanist; born 1748. died 1810). OHD.
