ELISENA. 



A small genus (ord. Amaryllidere) of handsome 

 greenhouse bulbs. Propagated by offsets in sandy 

 loam. Soil, light loam of good quality, with a 

 generous admixture of sand. 



Principal Species : 



longipetala, '2.' ', My., wh. 



ELISMA. 



(Ord. Alismacesr.) This is the proper name of 

 Alisma natans, a pretty little water plant, very 

 suitable for growing in shallow water outdoors or 

 in the tank inside. It is hardy, and is increased 

 by division or by seeds. 



Only Species :

ELLIOTTIA. 



A small genus (ord. Ericacea-) of dwarf ever- 

 greens. They do best in the greenhouse, but will 

 thrive out of doors in very favoured localities. A 

 compost of loam, peat, and sand is suitable. Prop- 

 agated by spring cuttings beneath a bell-glass or 

 by layering in summer. 



Principal Species : 



racemosa, 2', Je., wh. 



ELM (see also ULMUS). 



As a park tree, the English Elm (Ulmus campes- 

 tris) is in its right place. It is handsome when in 

 full leaf, rich in colour during late autumn, and a 

 decided ornament even when the leaves have 

 fallen. As an avenue tree the common Elm is 

 sometimes dangerous, for its huge, leafy branches 

 occasionally snap off suddenly in hot weather, 

 without any apparent cause. When planted in 

 suitable positions, Elms live to a great age, 

 and may reach a height of 100'. The wood is 

 tough, and used in boat building, wheel making, 

 anil for coffins. Some well-marked varieties are 

 even more ornamental than the type, and of these 

 antarctica aurea, pendula, and variegata are among 

 the best. The Scotch or Wych Elm (U. montana) 

 is a fine garden tree, and is well represented by 

 such varietal forms as the Parsley Elm (U. m. 

 crispa); the upright, large-leaved U. m. Dovsji; the 

 golden form known horticulturally as U. m. 

 Dampieri aurea, or Wredei aurea; the Camper- 

 down Elm (U. m. pendula) ; and the Purple-leaved 

 Elm (U. m. purpurea). Seedlings of both English 

 a.nd Scotch Elms are extensively used in forestry. 



ELYMUS. 



A genus (ord. Grarainea?) of hardy Grasses. They 

 will grow in any soil, and may be increased by 

 seeds or by division. The species vary in height 

 from 1' to 5'. Arenarius, the Lyme Grass, is used 

 for binding sandy soil on embankments. Cana- 

 densis, giganteus, sibiricus, and vaginatus are 

 sometimes found in cultivation. 



EMBELIA. 



A small genus (ord. Myrsinea?) of stove ever- 

 greens, grown for their foliage and berries. Equal

parts of loam and peat suit. Propagated by cuttings 

 of half-ripened wood in sand beneath a bell-glass 

 over bottom heat. The berries of E. Kibes are 

 j edible, though somewhat pungent.

EMBOTHRIUM. 



Several species were formerly included in this 

 genus (ord. ProteaceaV), but the majority have been 

 removed. The principal remaining species is the 

 beautiful coccineum, a greenhouse evergreen shrub. 

 In favoured places in Devon and Cornwall it grows 

 out of doors. Propagated by seeds. A compost 

 of three parts fibrous peat and one part fibrous 

 loam, . with ccarse sand, suits this South American 

 plant. 



Principal Species : 



coccineum, 20', My., Je., sc. 



EMILIA. 



Pretty annual or perennial plants (ord. Com- 

 positai) of which only a few may be named. These 

 are half-hardy annuals, which are useful for the 

 border or for cut bloom. They require the ordinary 

 treatment of flowers of their class, and may cither 

 be sown under glass in March, or in the border, 

 where they are to bloom, in May. 



Principal Species : 



flammea, 2', Jy., sc. (syn. Cacalia coccinea). 



soncihfolia, 2', Jy., pur. (syn. Cacalia sonchifolia). 



EMMENANTHE. 



A California)! genus (ord. Hydrophyllacea;) 

 needing greenhouse protection. 

 Principal Species : 

 pendulillora. 2', Jy., yel., pendulous flowers. 



EMPETRUM. (CnowiiERRY or CUAKI:- 



BERRY.) 



Neat little evergreen, Heath-like shrubs (ord. 

 Empetracere), with pink or reddish flowers, followed 

 by black or red berries, and growing well in a 

 damp spot filled with peaty soil. They are prop- 

 agated by cuttings in summer, inserted in sandy 

 soil under a bell-glass or hand-light, or by seeds 

 sown in spring or autumn. These germinate very 

 slowly. 



Only Species : 

 nigrum, 9", My., pk., scoticum, dwarf.

EMPLEURUM. 



There is only one species of note in this genus 

 (ord. Diosmea;). It is an evergreen shrub that 

 must be grown in the greenhouse, and may be 

 increased by cuttings of the tips of the growths 

 inserted in very sandy peat beneath a bell-glass. 

 A good compost consists of fibrous loam two parts, 

 peat one part, and enough sharp sand to ensure 

 porosity. 



Principal Species : 



serrulatum, 3', Je., pk. 



ENCELIA.

 greens that thrive in fibrous loam, peat, and sand.
