spored Alga?, comprising those species of 

 Ulva which have a tubular frond, whether 

 simple or more or less branched. The 

 most general species, E. intestinalis. known 

 by its bullate crisped fronds, occurs in fresh 

 as well as salt water, E. compressa being 

 the more common species on tidal rocks, 

 and having simple or branched narrower 

 fronds, dilated above. The species run 

 closely into each other, and are probably 

 too much multiplied. [M. J. B.] 



ENTIRE. Having no kind of marginal 

 division. 



EXTOPHYTE. A plant which grows i 

 from within others, as some rhizanths and 

 fun gals. 



ENULA-CAMPANA. (Fr.) Inula Sele- 

 nium. 



BOUSE. (Fr.) Quercus Ilex. 



EOUVE. (Fr.) Pinus Cembra. 



EPACRIDACE.E (Epacrids). A natural 

 order of corollifloral . dicotyledons, in- 

 cluded in Lindley's erical alliance of hypo- 

 gynous Exogens. Shrubby plants, with 

 usually alternate simple leaves ; flowers 

 regular and perfect, in spikes or racemes ; 

 corolla gamopetalous ; stamens five, equal 

 in number to the lobes of the corolla; 

 anthers one-celled, opening by a longitudi- 

 nal slit. Ovary superior, five-celled, with 

 five scales, distinct or combined at its 

 base. Fruit either fleshy or capsular ; em- 

 bryo with albumen and very small cotyle- 

 ! dons. There-are two sections of the order : 

 i 1. Epacrece, with a capsular many-seeded 

 I fruit : 2. SUipheliece, with a drupaceous one- 

 i seeded fruit. The plants are natives of 

 j the Indian Archipelago and Australia, and 

 I represent the hoaths in those countries ; 

 j but they differ from true heaths (Erica) in 

 ; their pentamerous symmetry, their anthers 

 ; being one-celled without appendages, and 

 in the attachment of the stamens and the 

 | corolla. 



They are cultivated in greenhouses for 

 I the beauty of their flowers. Some yield 

 I edible fruits. The berries of Leucopogcm 

 i Bichei, called native currants, are said to 

 I have supported the French naturalist 

 Hi che, who was lost for three days on the 

 south coast of New Holland. Astroloma 

 humifusum is called the Tasmanian cran- 

 berry. There are 32 known genera, and 336 

 species. Examples:— Epacris, Dracophyl- 

 lurn, Styphelia,Leucopogon. [J. H. BJ 



their flowers, are deservedly great favour 

 ites in the greenhouse. There is very much 

 diversity in the habits of the plants. In E. 

 pulchella, E.rigida, and E. microphylla, the 

 leaves are very small, and the flowers white. 



Epacris grandifiora. 



EPACRIS. A large genus typical of the 

 Epacridacece, distinguished by having a 

 coloured calyx with many bracts, a tubular 

 corolla with a smooth limb, stamens affixed 

 to the corolla, and a flve-valved many- 

 seeded capsule. They are branched shrubs 

 with the leaves lanceolate or cordate, 

 generally sharp-pointed, and the flowers 

 axillary, white red, or purple, usually in 

 leafy spikes. The species are distributed 

 over the extra- tropical portions of Austra- 

 lia, Tasmania and New Zealand, and many 

 of them, from the abundanceand beauty of 



In E. grandiflora the leaves are much larger, 

 ! heart-shaped and sharp-pointed, the flowers 

 ! nearly an inch in length, of a brilliant 

 ! reddish purple at the base, and pure white 

 i at the apex. In E. impressa, E. ruscifolia, 

 I and E tomentosa the flowers are of a deep 

 ! rose-colour ; while in E.nivea,E. obtusifolia, 

 E. heteronema, and E. paludosa they are 

 large aud of a pure white, the plants having 

 narrow lanceolate sharp-pointed leaves. 

 The New Zealand species are rather incon- 

 spicuous in their flowers. [R. HJ 



EPEAUTRE. (Fr.) Triticum Spelta. 



EPERUA. Th e Wallaba, E.falcata, a very 

 large timber tree, is the only member of 

 this genus of leguminous plants. It has 

 pinnate leaves composed of two or three 

 pairs of leaflets; and its red flowers are 

 borne in drooping long-stalked bunches. 

 The calyx consists of four thick concave 

 sepals with their bases connected, the 

 upper sepal being broader than the others ; 

 the corolla is a solitary roundish fringed 

 petal, inserted into the middle of the 

 calyx ; and there are ten stamens. The 

 curiously curved flat pod bears some re- 

 semblance to a hatchet, and generally 

 f ontains from three to four very flat seeds. 

 The tree is abundant in the forests of 

 British Guiana, where it attains a height 

 of fifty feet, with a girth of about six 

 feet. The timber is of a bright red-brown 

 colour, marked with whitish streaks, hard 

 and heavy, but rather coarse-grained. In 

 consequence of the readiness with which 

 it splits, it is commonly employed in 

 Demerara for shingles, palings, &c, and 

 being impregnated with a resinous oil, 

 it is very durable. The bark of the tree 

 is bitter, and the Indians employ a decoc- 

 tion of it as an emetic. They also use the 

 gum as an application to cuts. [A. SJ
