Leucoium continued. 



open, rich soil. If very heavy, an addition of a little 

 peat or leaf mould is recommended. Increased by offsets, 

 which should be secured as soon as possible after the 

 foliage ripens. Any of the species of Leucoium are ad- 

 mirably adapted for naturalising in the same way as 

 the Snowdrop, which they resemble in general appear- 

 ance, if a sufficient number of bulbs is obtainable. 



L. sestiyum (summer).* Summer Snowflake. fl. pure white, 

 about lin. long, the tip of each perianth segment marked with 

 green, both inside and out ; drooping ; clusters from four to eight- 

 flowered. Spring and early summer. I. linear, obtuse, with a 

 blunt keel. h. IJft. Central and South Europe (South 

 of England). An exceedingly pretty plant, and of easy culture 

 in any ordinary garden soil. See Fig. 398. (B. M. 1210.) 



L. autumnale (autumnal). This is the correct name of the plant 

 described in this work as Acis autumnalis. (B. M. 960.) 



L. Hernandez!! (Hernandez's).* fl. white, about iin. long ; 

 perianth segments oblong, obtuse, marked with a green spot ; 

 stem one to three-flowered. Summer. I. linear, about Jin. 

 broad, flat, obtuse, h, 1ft. to lift. Majorca. This species is 

 known in gardens as L. pulchellum. It is generally supposed to 

 be a variety of L. cestimim, but is not so ornamental, and is, 

 consequently, less grown. (L. B. C. 1478.) 



L. pulchellum (neat). A garden name of L. Hernandezii. 



FIG. 399. LEUCOIUM VERNUM, showing Habit and detached 

 Flower. 



L. vernum (spring).* Spring Snowflake. fl. white, with a green 

 spot on the tips of the segments, solitary, drooping, fragrant. 



Spring. I. few, linear, h. 4in. to 6in. Central Europe, 1596. 

 SYN. Erinosma vernum. A very handsome species, well sui 

 for either rockwork or the border. See Fig. 399. (B. M. 46.) A 



suited 



variety named biflorum is sometimes seen in gardens. (B. M. 

 1993),

 of North America and Japan. Flowers white, disposed 

 in terminal and axillary paniculate racemes. Leaves 

 alternate, petiolate, oblong or lanceolate, serrulate, per- 

 sistent or deciduous, penninerved. Leucothoes require 

 a peaty soil, or one composed of peat and leaf mould. 

 They are amongst the most desirable of hardy erica- 

 ceous shrubs. Propagated by seeds, which should be 

 covered very lightly ; by layers ; and by divisions of 

 established plants, in autumn or winter. Leucothoes, 

 like many other shrubs of a similar character, do not 

 grow very fast when young, or before being well esta- 

 blished.
