eluded, free, their anthers densely hairy at 

 the back ; and the pollen-masses adpressed 

 to an oblong truncate corpuscle. The 

 stigma is pentagonal and apiculate. The 

 follicles are smooth, slender, obtuse, and 

 divaricate, with comose seeds. [W. C] 



ECTOCARPE.E. A natural order of 

 dark-spored Algce, consisting of olive- 

 jointed threadlike seavreeds, whose spores 

 are mostly external, attached to the 

 branehlets or formed in a swelling of their 



j substance. It differs principally from 

 Chordariete in the less compound frond 

 and external spores. The fructification is 



I often of two kinds in the same species. 

 They are most abundant in temperate 

 regions, though several are found in warm 

 seas. [M. J. B.] 



ECTOOARPT7S. A genus of dark-spored 



Algce, with a branched threadlike jointed 



soft flaccid frond, and remarkable for the 



different aspects assumed by the fruit. 



The secondary form is disposed in podlike 



bodies, which are variously articulated. 



A good many species are found on our 



coasts, and are more easily distinguished 



; by their fruit than by the character of the 



j frond. The cells of the pods produce 



] zoospores. It is not quite certain whether 



■ the endochrome of the so-called spores is 



! ever resolved jnto zoospores. Ectocarpus is 



', known from Sphacelariaby the less elegant 



: branching, and the soft not rigid threads. 



These are sometimes collected in bundles 



by the action of the waves, but never essen- 



, tially combined, as in Mesoglcea. [M. J. B.] 



ECTONEURA Polybotrya. 



ECTOZOMA. A genus of Atropacece, 

 ; represented by a shrub, native of Ecuador, 

 : of somewhat climbing habit, and with 



flowers in terminal panicles. The calyx is 

 i thick, bell-shaped, with Ave triangular 

 | erect divisions ; corolla fleshy, tubular, 



somewhat dilated in the middle, its lobes 

 ! roundish, and overlapping before ex- 

 j pansion; stamens five, with very short 



filaments attached to a thin hairy ring 



surrounding: the ovary ; stigma globular. 



The fruit is unknown. [M. T. H.] 



ECFELLE D'EATJ. (Fr.) Hydrocotyle 



EDDOES. The tuberous stems of various 

 araceous plants, as Colocasia esculenta, 

 antiquorurn, &c, Caladium bicolor, violace- 

 um, and others. 



EDDYA. A genus of Boraginacece from 

 Texas and Jew Mexico, containing a 

 small much-branched very hispid prostrate 

 undershrub with crowded leaves and soli- 

 tary axillary white flowers ; corolla salver- 

 shaped, naked at the throat ; stamens 

 inserted at the apex of the tube of corolla ; 

 nuts ovate, cohering by their internal 

 angles, muricate. [J. T. S.] 



EDENTATE. Not having teeth. 



EDGED. When one colour is surrounded 

 by a very narrow rim of another. 



EDGWORTHIA. A genus of plants be- 



longing to the Tliymelacere, named by C. A. 

 Meyer in honour of Mr. Edgworth, an 

 Indian botanist. The flowers have a single 

 perianth, the limb of which is divided into 

 four ovate blunt lobes. There are no 

 perigynous scales, but one emarginate 

 hypogynous one; stamens eight, nearly 

 sessile, arranged in two distinct lines, one 

 above the other ; ovary covered with hairs, 

 one-celled, containing a single suspended 

 ovule; style threadlike, ending in an 

 elongated awl-shaped stigma. There are 

 two species of the genus, E. chrysantha, 

 found in Chusan by Mr. Fortune, a shrub 

 with yellow flowers, and oblong-lanceolate 

 leaves of a very dull green, covered with 

 hairs closely pressed to the surface ; and 

 E. Gardneri, found in Nepal. [J. H. BJ 



EDMONSTONIA. A genus of plants 

 named after Thos. Edmonstone of Shet- 

 land, naturalist of the Herald. It belongs 

 to the Samydacece, and has a coloured 

 persistent four-cleft perianth ; four sta- 

 mens inserted into the bottom of the 

 calyx, the filaments free, the anthers in- 

 trorse ; and a free one-celled ovary with 

 three parietal placentas, and numerous 

 ovules. There is one known species, E. 

 pacifica, which is a shrub ten to twelve 

 feet high, native of the promontory of 

 Corrientes in Darien. [J. H. B.] 



EDRAIANTHTTS. The generic name of 

 plants belonging to the order of bellworts, 

 and characterised by the number five pre- 

 vailing in the flower; the stamens free, 

 their filaments broad at the base; the 

 ovary with two or three cells ; and the 

 seeds ovate and plain. The name is de- 

 fined from Greek words signifying ' sessile 

 or stalkless flower.' The species are natives 

 of Southern Europe, and usually in the 

 form of small tufted herbs with narrow 

 alternate leaves, which are often furnished 

 with stiff hairs ; the individual flowers 

 are stalkless but grouped in heads. [G. D.] 



EFFLORESCENT. The action of begin- 

 ning to flower. 



EFFOLIATION. The removal of leaves. 

 EFULCRATE. Said of buds from below 

 which the customary leaf has fallen. 



EGENOLFIA. Pohjbotrya. 



EGER1A. A genus of ffydrocharidacece 

 from South America, consisting of water 

 plants with the habit of Anacharis, having 

 dicbotomous branches and verticillate 

 linear leaves with finely serrated margins. 

 The spathe of male flowers is axillary and 

 sessile, the flowers themselves resem- 

 bling those of Hydrocharis ; female flowers 

 unknown. [J. T. SJ

 longena) and ovigerum.
