EQU 



Equitant. A mode of vernation, or of ar- 

 rangement of leaves with respect to each 

 other, in which the sides or edges alter- 

 nately overlap each other, as in Morcea 

 iridioides. 



Erectly-spreading. Between erect and 

 spreading. 



Erecto-patent. Between erect and spread- 

 ing. 



Eremus. A ripe carpel separating from its 

 neighbors and standing apart. 



Ergot. A disease of Corn, Rye, etc., pro- 

 duced by Fungi. 



Erianthus. When some parts of a flower 

 are covered with a woolly or cottony pu- 



Ericacece, (Heathworts.)A. natural order of 

 CoroUifloral Dicotyledons, typical of 

 Lindley's Erical Alliance. They are shrubs 

 or undershrubs, with evergreen, rigid, 

 entire, whorled, or opposite leaves with- 

 out stipules. Arbutus Unedo is the Straw- 

 berry Tree. Rhododendron arboreum some- 

 times reaches in India a height of forty 

 feet, and some species grow at an eleva- 

 tion of 16,000 to 18,000 feet in the Hima- 

 layas. Several species of Azalea, Rhodo- 

 dendron, and Kalmia are natives of the 

 United Statea The plants of this order 

 are highly prized for the beauty of their 

 flowers. There are about fifty known 

 genera and nine hundred species. Erica, 

 Rhododendron, Kalmia, Clethra, Arbutus, 

 and Ledum are examples of this order. 



Erinus. Prickly, rough. 



Eriocaulacece, (Pipeworts.)-A. natural order 

 of incomplete Monocotyledons, included 

 in Lindley's Glumal Alliance among the 

 Endogens. They are marsh plants, with 

 narrow, spongy leaves. There are ten 

 known genera and two hundred and 

 twenty species. Eriocaulon, Cladocaulon, 

 and Philodice are examples of the order.

 larly toothed, as if bitten by an animal; a 

 term used to express a particular kind of 

 denticulation, as in Salvia pinnata.

Escalloniacece, (Carpodetece, Escalloniads.) 

 A natural order of Calycifloral Dicotyle- 

 dons belonging to Lindley's Grossal Alli- 

 ance of epigynous Exogens. They are 

 evergreen shrubs, often odoriferous, with 

 alternate exstipulate leaves, and axillary, 

 conspicuous flowers. The order is con- 

 sidered by Bentham and Hooker as a 

 tribe of Saxifragacece, with which they 

 similarly unite Ribesiacece. The plants are 

 chiefly natives of South America, but some 

 are found in the southern parts of Aus- 

 tralia and New Zealand. There are seven 

 known genera and about sixty species. 

 EscaUonia, Itea, and Carpodetus are exam- 

 ples of the order. 



Escens. A termination equivalent to the 

 English ish ; thus, rabescens, reddish. 



Essential,. The most prominent character-
