ELLIOTTIA (named in honour of Stephen Elliot, 

 an American botanist, who died in 1830). STN. Trt- 

 petaleia. OBD. Ericaceae. A genus of three species of 

 very pretty half-hardy evergreen shrubs, two of which 

 are Japanese (these are probably not at present in 

 cultivation), and the third North American. The one 

 mentioned below does well in a warm situation, in a 

 peaty soil. Propagated by cuttings.

 of Ceratopteris thalictroides.

ELODEA (from elodes, growing in watery places). 

 Water Thyme. STN. Udora. OBD. Hydrocharidea. A 

 genus of unattractive slender aquatic perennials. There are 

 eight species, none of which are worth growing. E. cana- 

 densit merits mention in this work from the fact that its 

 extremely rapid increase often entails no little work on the 

 gardener. It was introduced from America to County 

 Down about 1836, and into England in 1841. Very soon, 

 it filled a number of canals and rivers with its dense, 

 matted growths to such an extent as seriously to impede 

 navigation. No inconvenience of this kind is complained 

 of in its native country. In many places now (fish ponds, 

 ornamental waters, Ac.), where at one time it was so 

 abundant, it seems to have almost disappeared, perhaps 

 owing to the exhaustion in the soil of the specific nutri- 

 ment on which the plant feeds. 



ELONGATED. Lengthened out. 

 ELYMUS (from elumot, the old Greek name for a 

 similar grass, used by Hippocrates). Bunch Grass. OBD. 

 Gramineas. A genus of about twenty species of tall 

 perennial grasses, represented in Britain by the Lyme 

 Grass, E. arenarius, a sea-side plant, useful for fixing, 

 by means of its long creeping rhizomes, the moving sand. 

 All are natives of North temperate regions. E. con- 

 densatu* is described as a vigorous perennial grass, from 

 British Columbia, forming a dense, compact, column-like 

 growth, more than 8ft. in height, covered from the base 

 almost to the top with long arching leaves, and crowned 

 in the flowering season with numerous erect, rigid spikes, 

 each 6iin. long, and resembling an elongated ear c 

 Wheat in form. 



EMARGINATE. Having a small notch at the end 

 or tip : as if a piece had been taken out. See Fig. 702. 



EMBELIA (Ceylonese name of one of the species) 

 OBD. MyrsinecB. A genus of mostly stove climbing 

 shrubs, or small trees. Flowers white or greenish-yellow, 

 small polygamous, mostly dioecious. Fruit small, globose 

 one (rarely two) seeded. Leaves entire or toothed; pe- 

 tioles often margined or glandular. Embelias thrive in 

 a compost of peat and loam. Propagated by cuttings 

 made of half-ripened shoots, and placed in sandy soil 

 under a bell glass, in heat. There are about i

 undulate or obscurely serrulate, rusty-pubescejit,

 cultivation. 

 Lrobuata (robust). L< 

 acuminate, undulate 

 or rarely glabrous beneath. __ . . . 



A. 20ft India. A large rambling shrub, 



EMBOSSED. Projecting in the centre, like the boss, 

 >r umbo, of a round shield or target. 



EMBOTHRITJM (from <m, in, and bothrion, a little 

 pit; referring to the pollen-cases, or anthers). OBD. 

 roteacece. A genus of four species of very ornamental 

 evergreen shrubs. AH are natives of the Andes, or 

 extra-tropical South America. They require proteo- 

 ion throughout the winter, in cold, northerly situa- 

 ions. In the southern counties of England, the one 

 lere described is quite hardy. For culture, see Core- 

 throstylis. 



E. coccincum (scarlet).* . orange scarlet, long, pendent ; pe- 

 rianth tubular, with a sub-globose four-cleft liuib, bearing the 

 sessile anthers on the concave lobes. Summer. I. simple, entire, 

 oblong. A. 5ft 1881. (B. M. 4856.) 



EMBRACING. A leaf is said to Embrace a stem 

 when it clasps the latter round with its base. 



EMBRYO. The rudimentary plant within the seed. 



EMERGENT. Protruded through the cortical layer. 



EMERICIA. A synonym of Vallaria. 



EMMENANTHE (from emmenot, enduring, and nn- 

 Ihot, a flower; in reference to the persistent corolla). 

 STN. Miltitzia. OBD. Hydrophyllaceae. A genus of 

 dwarf annual herbs, containing five species, natives of 

 North-west America. Flowers yellow; corolla campann- 

 late, marcescent, persistent. Leaves alternate. None of 

 bhe species are yet in general cultivation. 



EMPETRACEJE. A natural order of Heath-like 

 evergreen shrubs. Flowers small, solitary or clustered, 

 axillary or terminal, regular, polygamous, bracteolate or 

 not. Fruit fleshy. Leaves alternate, exstipulate. The 

 distribution of the order is North temperate and Arctic 

 zones, Chili, and Fuegia. There are only four species. 

 The order is represented in Britain by Empetrvm nigrvm, 

 the fruit of which is eaten in some countries. The three 

 genera are: Ceratiola, Corema, and Empetrwn. 



EMFETRUM (Empetron, the Greek name of a plant 

 used by Dioscorides, from en, 

 upon, and petrot, a rock ; in allu- 

 sion ' to the place of growth). 

 Crakeberry, or Crowberry. OBD. 

 Empetracect. An ornamental 

 hardy evergreen, low, spreading, 

 Heath-like shrub. Flowers mi- 

 nute, axillary, dioecious. Fruit a 

 small berry-like drupe. Leaves 

 small, crowded, entire, evergreen. 

 They are well adapted for grow- 

 ing in damp, peaty situations. 

 Propagated readily, in summer, by 

 cuttings, which should be placed 

 in sandy soil, under a handlight.
