 RUINS are a class of buildings beautiful 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 imperfection 

 and obscurity are their properties, and to carry the 

 imagination to something greater than is seen, their 

 effect.

 Polygynia. 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 fibrous peat. Winter 

 temp., 50 to 55 ; summer, 60 to 80.

Hardy herbs, mostly weeds, but R. Acetosa is the 

 common Sorrel. The others mentioned here are used in 

 a similar way, perhaps, more often in France than in this 

 country. Seeds ; divisions. Ordinary soil.

RUN. A plant advancing to seed is said by gardeners 

 to have run. Also, when the dark colouring of a carna- 

 tion, or other flower, becomes confused or clouded with 

 a 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 distinct ; over- fertility 

 or poverty of soil will equally cause the colours to run. 



RUNCINATE, or LION-TOOTHED, describes the edge 

 of a leaf cut into transverse sharp-pointed segments, 

 pointing backwards, as in the leaf of the Dandelion. 



RU'NGIA. (Commemorative of F. F. Rungia, a 

 German. Xat. ord. Acanthaceae.) 



Stove evergreens. Cuttings in sand in a case, kept 

 close and warm. Fibrous loam, leaf-mould, and a little 

 sand.

 from the Celtic brus, box, and kelen, holly ; Box Holly, 



or Butcher's Broom. Nat. ord. Lily-worts [Liliaceae]. 

 Linn. 6-Hexandria, i-Monogynia.) 



Hardy evergreen shrubs. Suckers, and dividing the 

 roots ; any common, rich soil. Andro'gynus is a green- 

 house evergreen climber, and, like the rest of the Butcher's 

 Brooms, retains the singularity of producing its flowers 

 and fruits on flattened, leaf-like branchlets.

 Natural History of Aleppo. Nat. ord. Figworis [Scrophu- 

 lariaccce]. Linn. i^-Didynamia, 2-Angiospermia.) 



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.

RUOT. 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 explanation. 

 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 pre- 

 mature rapidity of growth. Any excessive pressure 

 upon the cuticle, whether from within or without, causes 



RUSTIC STRUCTURES are pleasing in recluse portions 

 of the pleasure-ground, if this style be confined to the 

 formation of either a seat or a cottage ; but it is ridiculous, 

 if complicated, and elegant forms are constructed of 

 rude materials. Thus we have seen a flower-box, in- 

 tended to be Etruscan in its outlines, formed of split 

 hazel stakes a combination of the rude and the refined, 

 giving rise to separate trains of ideas totally unassociable. 



RU'TA. Rue. (From rus, to flow; from some re- 

 puted medicinal virtue. Nat. ord. Rueicorts [Rutacea?]. 

 Linn. R-Octandria, \-Monogynia.) 



Seeds in spring ; also by cuttings under a hand-light 

 in sandy soil, in a shady place, in summer. They flourish 

 best in a deep, sandy loam, with limy rubbish mixed.
