RUN 



RYT 



clouded with its lighter ground colour, 

 they say it is a ntnjloicer. Abundance 

 of moisture and a rich soil promote the 

 development of leaves, and, conse- 

 quently, check running, or producing 

 seed. A suitably fertile soil also pre- 

 serves the colours of a ilower pure and 

 distinct over-fertility or poverty of 

 soil will equally cause the colours to run. 

 Ru'scus. Butcher's Broom. (From 

 bniscus, derived from the Celtic Icnx, 

 box, and kelem^ holly ; Box-holly, or 

 Butcher's Broom. Nat. ord., Lily worts 

 [Liliaceffi]. Linn., G-Hcxandria \-Mo- 

 nogynia.} 



Hardy evergreen shrubs. Suckers, and di- 

 viding the roots ; any common, rich soil. An- 

 drogynus is a greenhouse, evergreen climber, 

 and, like the rest of the Butcher's Brooms, 

 retains the singularity of producing its flowers 

 and fruits on the edges of the leaves.

RUSH BROOM. Vimlna'ria. 



RUSSE'LIA. (Named after Dr.'Russel, 

 author of a Natural History of Aleppo. 

 Nat. ord., Fiyivorts [Scrophulariacefe], 

 Linn., l-i-Didynamia S-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.

RUST. A disease of the berries of j 

 the grape. It appears in the form of 

 a rough, rusty appearance of their I 

 skins, which have, in fact, become \ 

 thick and hardened. Some think it j 

 arises from the berries being handled, I 



or the hair of the head touching them ; 

 but the disease is often too general to 

 admit of this topical explanation. Y\"c 

 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 from without, 

 causes its thickening. 



RUSTIC STRUCTURES are pleasing in 

 recluse portions of the pleasure-ground, 

 if this style be confined to the forma- 

 tion 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, intended 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 rtis, to flow ; 

 from some reputed medicinal virtue. 

 Nat. ord., Eucworts [Rutacere]. Linn., 

 8-Octnndria l-Monoyi/nia.) 



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. See Rue.

 sand, under a glass, in a hotbed; fibry loam 

 and leaf-mould. Winter temp., 5i to 60;
