 and Leaves. 



D. Mezerenm (Mezereuni).* Common Mezereon ; Spurge Flax ; 

 Spurge Olive. /. red, distributed over the branches mostly in 

 threes, and in pairs and fours, expanding before the leaves 

 appear. February, March, or April. I. lanceolate, membranous, 

 2in. to 2in. long, obtuse or acute, shortly petiolate. A. 3ft, to 4ft. 

 Europe (England, but very rare, perhaps not indigenous). A 

 slender, straggling, deciduous shrub. The bark of this species is 

 very acrid, and is used medicinally, for which purpose it is largely 

 imported from Germany. There are white, red, and autumnal- 

 flowering varieties. 



D. odora (sweet-scented).* JL purple, fragrant ; heads terminal, 

 sessile, many-flowered. March. L scattered, oblong-lanceolate, 

 smooth. A." 3ft China, 1771. Greenhouse evergreen. (B. M. 

 1587.) 



D. o. Maxell (Mazel's).* JL white, pink, sweet-scented, borne on 

 short lateral branchlets all along the branches, and thus differing 

 from all the other varieties of D. odora. It produces its flowers 

 from November until spring, and succeeds best in a partial! v 

 shaded position. (Gn., Nov. 1878.) 



D. oleoides (Olive-like), f.. white, terminal, sessile, a few 

 together, and surrounded by leaves that in some measure invo- 

 lucrate them. April. 7. obovate-lanceolate, terminated with a 

 minute mucro, glabrous on both sides, glossy. A. 2ft South- 

 east Europe, 1818. A hardy evergreen shrub. (B. M. 1917.) 



O. pontica (PonticX* fl. greenish-yellow, fragrant, bractless, 

 glabrous, in many-flowered upright clusters, each of the long 

 partial stalks of which bears two flowers. April and May. I. 

 obovate-lanceolate, glabrous, h. 4ft to 5ft Eastern Europe, 

 etc., 1759. A hardy, spreading, branchy, evergreen shrub. (B. M. 

 1282.) There is a form with variegated leaves, but it is rare. 



D. striata (streaked), /t. rosy-purple, Carnation-scented, terminal, 

 aggregate. June and July. I. sub -spat hulate-linear, sessile, 

 AT2ft. Europe, 1819. A hardy evergreen, forming dense, twiggy, 

 spreading masses, 1ft to 3ft across.

DARLINGTONTA (named in honour of Dr. Darling- 

 ton, an American botanist). OBD. Sarracenvaceae. A very 

 curious and remarkable hardy herbaceous monotypic 

 genus, allied to Sarracenva, but without the curious 

 umbrella- shaped summit to the style, which is so con- 

 spicuous in the latter. It is an admirable plant for grow- 

 ing in the greenhouse, in conjunction with Cephalotns, 

 Drosera, Sarracenia, Ac., and requires the same cultural 

 treatment. Out of doors, it thrives best in a damp and 

 shady position, in the rockery or f emery, where it must 

 be kept well supplied with water. The best soil is 

 one composed of peat and chopped sphagnum, to which 

 plenty of sharp sand and small pieces of limestone are 

 added. Darlingtonias should have the protection of a 

 handlight, which is preferable to a bell glass, as venti- 

 lation may be more easily given. It is usually con- 

 sidered somewhat difficult to get the seeds to germinate 

 and grow. The following mode of treatment has, however, 

 been found successful : The pots should be filled, within 

 lin. of the top, with fibrous peat, charcoal, fresh-chopped 



Darlingftonia conttniud. 



sphagnum, and sand, in equal parts, then coated with fresh 

 tips of sphagnum. On this the seeds should be sprinkled, 

 and well watered, the pots being stood in pans of water, and 

 covered with a bell glass, in order io keep the atmosphere 

 above the seeds in a moist condition. The pots should 

 then be placed in a shady position in a cool greenhouse, 

 and in about five or six weeks the seeds will commence 

 germinating. When strong enough, the seedlings should 

 be pricked off into pans filled with the same compost as 

 above mentioned, and transferred to a cold, shady frame, 

 where they must be kept constantly moist Perfect 

 drainage and a cool, shady position, are at all times 

 absolutely

 red-brown veins, oblong. April. I. , or pitchers, slender at the 

 base, gradually swelling upwards ; apex bent over, or hood-like, 

 with a large triangular process depending from the aperture ; 

 ground colour bright green, upper portion and throat beautifully 

 mottled with white, and reticulated with reddish-pink veins.

 author of a once famous poem entitled ''The Botanic 

 Garden"). SINS. Genetyllif, Hedaroma, and Polyzone. 

 OBD. Myrtac&B. A genus of greenhouse, Heath-like, ever- 

 green shrubs ; there are upwards of a score species known, 

 all natives of Australia. Flowers red or white, in terminal 

 fascicles, inclosed in large, coloured, ovate or oblong 

 involucres, and interspersed with chaffy bracts. Leaves 

 scattered, full of pellucid dots. For culture, Ac., tee 

 Calythrix. 



D. citrlodora (Lornon-scented). ./f. usually four, in small 

 terminal heads ; involucre scarcely exceeding the flowers, con- 

 sisting usually of four outer leaf -like bracts, and four inner ovate 

 ones, more or less coloured. L nearly opposite, from narrow. 

 oblong to almost ovate-lanceolate, obtuse. A. 1ft to 2ft Sr.v 

 Hedaroma latifolium. 



D. dlosmoldes (Diosma-like). fl. white, numerous, in compact 

 terminal globular heads ; calyx about one and a half lines long, 

 the adnate part obscurely five-ribbed, and covered nearly from the 

 base by glandular papillw more or less distinctly arranged in six 

 to eight prominent parallel rings ; petals white. April. L scat- 

 tered; crowded, linear, semi-terete or triquetrous, thick or slender,
