RUINS are a class of buildings beau- 

 tiful as objects, expressive as characters, 

 and peculiarly calculated to connect with 

 their appendages into elegant groups : 

 they may be accommodated with ease to 

 irregularity of ground, and their disorder 

 is improved by it ; they may be intimately 

 blended with trees and with thickets, and 

 the interruption is an advantage, for im- 

 perfection and obscurity are their proper- 

 ties, and to carry the imagination to some- 

 thing greater than is seen, their effect. 



RUI'ZIA. (Named after H. Ruiz, co- 

 author with Pavon of the Flora Peruvi- 

 ans Nat. ord., Byttneriads [Byttneria- 

 cese]. Linn., \Q-Monadelphia S-Poly- 

 gynia. Allied to Dombeya.) 



Stove, white-flowered evergreens, from the Isle 

 of Bourbon. Cuttings of half-ripened side-shoots 

 in summer, in sandy soil, under a bell-glass, but 

 raised at night, and in a mild hotbed ; sandy 

 loam and fibry peat. Winter temp., 50 to 55 ; 

 summer, 60 to 80. 

 JR. loba'ta (lobed-leaved). 6. 1816. 



varia'bilis (variable-/med). 6. May. 17Q2. 



EUNCINATE, or LION-TOOTHED, describes 

 the edge of a leaf cut into transverse 

 sharp-pointed segments, pointing back- 

 wards, as in the leaf of the Dandelion. 



RUN. A plant advancing to seed is 

 said by gardeners to have run. Also, 

 when the dark colouring of a carnation, 

 or other flower, becomes confused or 

 clouded with its lighter ground colour, 

 they say it is a run flower. Abundance 

 of moisture and a rich soil promote the 

 development of leaves, and, consequently, 

 check running, or producing seed. A 

 suitably fertile soil also preserves the 

 colours of a flower pure and dist?.?2ot; 



over-fertility or poverty of soil will equally 

 cause the colours to run. 



Ru'scus. Butcher's Broom. (From 

 bruscus, derived from the Celtic beus, box, 

 and kelem, holly; Box Holly, or But- 

 cher's Broom. Nat. ord., Lilyworts [Li- 

 liacese]. Linn., Q-Hexandria 1-Mono- 

 gynia.) 



Hardy evergreen shrubs. Suckers, and dividing 

 the roots ; any common, rich soil. Andro'gynus 

 is a greenhouse evergreen climber, and, like the 

 rest of the Butcher's Brooms, retains the singu- 

 larity of producing its flowers and fruits on the 

 edges of the leaves.

RUSSE'MA. (Named after Dr. Russel, 

 author of a " Natural History of Aleppo." 

 Nat. ord., Figiuorts [Scrophulariaceae]. 

 Linn., 14:-Didynamia 2-Anyiospermia.) 



Stove, red-flowered evergreens, from Mexico. 

 Cuttings in sandy soil, in heat ; also frequently 

 by suckers. If a large branch is allowed to lie 

 along the ground in a warm, moist place, plenty 

 of plants will be made from its twigs rooting ; 

 sandy loam, peat, and leaf-mould. Winter 

 temp., 45 to 55 ; summer, 60 to 85. 

 R. floribu'nda (bundle-flowered). 4. 1824. 



ju'ncea (rushy-branched). 3. July. 1833. 



multiflo'ra (many-flowered). 4. July. 1812.

 RUST. A disease of the berries of the 



grape. It appears in the form of a rough, 

 rusty appearance of their skins, which 

 have, in fact, become thick and hardened. 

 Some think it arises from the berries 

 being handled, or the hair of the head 

 touching them ; but the disease is often 

 too general to admit of this topical ex- 

 planation. We believe it to arise from 

 an over-heating and sudden reduction of 

 temperature of the vinery whilst the 

 grapes were young, and thus tending 

 to force them to a premature rapidity of 

 growth. Any excessive pressure upon 

 the cuticle, whether from within or with- 

 out, causes its thickening. 



RUSTIC STRUCTURES are pleasing in 

 recluse portions of the pleasure-ground,
