ELL 



Elliptic. A flat body which is oval and 

 acute at each end. 



Elliptic-lanceolate. A form between elliptic 

 and lanceolate, as in Olea Americana. 



Elongate, Elongated. Lengthened or 

 stretched out; when any part of an organ 

 is in any way remarkable for its length 

 in comparison with its breadth. 



Emarcid. Flaccid, wilted. 



Emarginate. Having a small notch in tha 

 end, as if a piece had been taken out, as 

 in Canna coccinea. 



Embolus. A plug; a process which projects 

 downward from the upper part of the 

 cavity of the ovary in Armeria, and closes 

 up the foramen of the ovule. 



Embossed. Projecting from the surface, 

 like the boss or umbo of a round shield 

 or target. 



Embracing. Clasping with the base. The 

 same as amplexicaul, which see. 



Embryo, (adj. Embryonal.) The rudiment 

 of a plant contained in the seed. Ic 

 makes its first appearance soon after the 

 pollen has fertilized the ovule. Fixed 

 embryo, a leaf bud. 



Embryo buds. Spheroidal solid bodies, re- 

 sembling woody nodules, formed in the 

 bark of trees, and capable of extending 

 into branches under favorable circum- 



Embryotegium, Embryotega. A little papilla, 

 often separating as a lid, which covers 

 over the radicle of some kinds of embryo. 

 It is the hardened apex of the nucleus. 



Empetracece, (Crowberriea.) A natural or- 

 der of monochlamydeous Dicotyledons 

 belonging to Lindley's Euphorbia! Alli- 

 ance. They are shrubs with heath-like, 

 evergreen leaves without stipules, and 

 small axillary flowers, Avhich are usually 

 imperfect. The fruit is fleshy, with two 

 to nine nucules; seed solitary. They are

natives chiefly of the northern parts of 

 Europe and America. There are four 

 known genera and five species. Empe- 

 trum, Ceratiola, and Corema are examples 

 of the order. 



Emphysematose. Bladdery; resembling a 

 bladder. 



Endeca. In Greek compounds means 

 eleven. 



Endecagynous. Possessing eleven pistils. 



Endecandrous. Possessing eleven stamens. 

 No flowers are strictly characterized by 

 possessing either eleven stamens or 

 eleven pistils, but as such conditions oc- 

 cur from accidental abortions or mon- 

 strous developments, the terms are in use. 



Endocarp. The lining of a carpel; the in- 

 ner surface or lining of a fruit, represent- 

 ing at that time the upper surface of a 

 carpellary leaf. The stone of a Cherry is 

 its endocarp. 



Endogens. A large class of plants to which 

 the names of Monocotyledones and Amphi- 

 bryce are also given. " They have a cel- 

 lular and vascular system, the latter 

 exhibiting spiral vessels. Their stem 

 is endogenous, that is to say, increases 

 in diameter by the addition of woody 

 vessels towards its interior, the outer 

 part being the oldest and densest, and 

 hence the name Endogens, inward grow- 

 ers; bundles of woody, spiral, and pitted 

 vessels are scattered throughout the cel- 

 lular tissue; there is no pith, no separ- 

 able bark, no woody rings or zones, and 

 no true medullary rays. The age of 

 woody Endogens cannot be determined 

 by counting concentric rings, as in Exo- 

 gens. The leaves are usually continuous 

 with the stem, and do not fall off by ar- 

 ticulations; and when at length they sep- 

 arate, their bases leave marks or scars at 

 definite intervals on the stem, as may be
