the perigyrioiis andliygogynous flowers. 

 The epigynoua disk is a name given 

 either to the thickened summit of the 

 ovary in epigynOus flowers, or very 

 rftrely to the real disk or enlargement 

 of the receptacle closing over the ovary. 

 EpiPHLa'ODAL — Existing superficially on 

 the epidermis of bark. 



Ep'ipHragm — In Nidulariese, a delicate 

 membrane closing the cup-like sporo- 

 phore. 



Epiph'tllous, Epiphtl'lus— Either grow- 

 ing upon or inserted on the leaf, as 

 many Fungi and Lichens. In the case 

 of the Cactus called EpiphyUum, the 

 genus is only so named from the 

 flattened branches having somewhat the 

 appearance of leaves. 



Epiphyte', Epi'phyton — Plants which at- 

 tach themselves to others for support, 

 but derive no nutriment from them. 

 They simply grow upon other plants 

 without penetrating into their tissue. 

 (See the native species of Dendrohiums, 

 Stag's-horn Perns, &c.) 



Epispebm', Epispeemium — The seed-cover ; 

 used ■ synonymously with "Lorica," 

 "Perisperm," and "Spermodermis." 



Epispobb' — The outer integument of a. 

 spore. 



Episto'meus — Spigot-shaped. 



Epithal'lus — Cortical layer of Lichens. 



Epithe'cicm— The expanded coloured disk 

 of the apothecium. 



Epiz'oio — Growing upon animals. 



Equinoo'tial— Plants whose flowers expand 

 and close at particular hours of the day. 



E'qcitant, Eqtiitativus — A form of verna- 

 tion, in which the leaves are folded 

 forwards longitudinally on the mid- 

 rib, so that their edges meet, and each 

 embraces the one which is placed next 

 within it. (See Oberonia iridifolia.) 



Ee'emos — Solitary, as Ehemophila, a lover 

 of the desert ; Eebmostachts, a soli- 

 tary or deserted spike. 



Eeioe'tinus— Growing on heaths. 



Eei'nus— Prickly, rough. 



Eeineum — A diseased state of the tissue, at 

 one time believed to be produced by a 

 fungus. The trees of Mallotus phtlip- 

 pinensis frequently have their young 

 shoots deformed by this disease. 



Eeio'phoscs — Bearing wool, or covered 

 with woolly or downy pubescence. 



Eeose' — Gnawed. Eeoded— Having the 

 margin irregularly toothed as if bitten 

 by an animal. 



Ee'ehine— Promoting a discharge of mucus 

 from- the hostrils. 



Eeum'pbnt — Applies tocertain fungi whose 

 fructification bursts through the tex- 

 . ture of leaves, &c. 



Es'otlLENT, . ESCULENT0S— Good for food. 

 Example, Hibiscus esculentns, the 

 .Oohro or Gombo. 



Essen'tial Oils — Thete is no reason why 

 maity such plants, as Lavender, Ani- 

 seed, Caraway, the Mints, &c., as well 

 as a number of the indigenous plants, 

 should not be grown in this dolony for 

 the sake of their oils. Mower-farming 

 is an industry in the neighbouring 

 colonies, and f romsamples lately tested 



it is reported thatlOOlb. of the Pepper- 

 mint plant produced 4 oz. of oil, and 

 loz. of oil from 301b. of- Spearmint; 

 3 oz. of oil was also obtained from 20 lb. 

 of the stems and leaves of Zavendula 

 vera. Our Brisbane Pennyroyal 

 {Mentha satureioides) has been known 

 to yield, from 1001b. of the plant, 7 oz. 

 of oil, equal to the best peppermint. 

 Of our trees those which have yielded 

 oil of the best quality, as well as the 

 -greatest quantity, are Eucalyptus 

 hcemastoma, E. microcorys, E. rrmculata, 

 var. citriodora, E. Staigeriana, Mela- 

 leuca leiieaderidron, M. linariifolia, 

 and Baokhousia citriodora. 

 Esd'kiale — Appeasing hunger, as the 

 fruits of Solanum esuriaiey by the 

 natives. 

 Et^i'eio, ETA'iRinM — A fruit composed of 

 several distinct one-seeded pericarps 

 (akenia and caryopses of different 

 anthers, or drupellae), arranged u^ou 

 an elevated receptacle or torus, which 

 may be either dry or fleshy. Eor 

 examples see Banuncidus (Buttercup), 

 Fragaria (Strawberry), and Ruhus 

 (Blackberry or Raspberry). 

 Etiola'ted, Etiola'tus — The effect _ of 

 blanching the leaves, and lengthening 

 of the stem when a plant is suffered to 

 grow in the dark, or in a much 

 obscured situation. 

 Evanes'cent, Evanes'ceNS— Vanishing ; 

 applies to veins which do not reach the 

 margin. 

 Ex, in composition, signifies without ; as 

 exalbuminous seeds, as the common 

 garden Been and Pea, which contain 

 an embryo only. 

 Exaspeea'tus — Rough. (See cap of 



Lentinus exasperatvs. ) 

 ExoiP'tJLUM— Receptacle of a Lichen. 

 Exoue'eent, Exoureens — Protruding be- 

 yond the usual limits. 

 Exhala'tion, Bxhala'tis — A vital func- 

 tion by which the stomata are made to 

 discharge a large portion (about two- 

 thirds) of the water introduced by 

 absorption through the spongioles. 

 Exi'gdds— Very puny and pitiful. (See the 



small orchid, ButbophylJ/wm exiguum.) 

 Ex'oGENB, Bxo'gens— Used synonymously 

 with "Dicotyledons," because the 

 stem of such plants have an exogenous 

 structure, which consists of (1) pith, 

 (2) medullary sheath, (3) wood, dura- 

 men, and alburnum, (4) medullary 

 rays, (5) bark. 

 ExosHi'z AL, ExoEHizus — The peculiar m ode 

 in which the radicle of dicotyledons is 

 developed in germination ; elongating 

 at once from the radicular extremity of 

 the embryo, and not bursting through 

 an outer coat, as in monocotyledons. 

 Exosmosb', Exosmo'sis— The effect opposed 

 to Endosmose, referring to the current 

 which passes from within outwards. 

 ExospOEiDM, ExospOEE — The outer 

 membrane of the coat of a spore. 

 ExoSTOME', Exos'toma— The perforation in 

 the primine or testa which, together 

 with the endostome, completes th<
