Ruizia

Two species. Stove evergreen shrubs. Cuttings. Loam, peat and sand.

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 distinct - over-fertility or poverty of soil will equally cause the colours to run.

Runners

Runners are young shoots issuing from the collar or summit of the root, and creeping along the surface of the soil, but producing a new root and leaves at the extremity, and forming a new individual, by the decay of the connecting link. This takes place in a great variety of herbs, but particularly the strawberry, which is a good example.

They afford very ready and unfailing means of increasing the species or variety, all the care required being to see that the plantlet is well rooted before the connecting string is divided.

Ruscus

Butcher's Broom. Five species. Chiefly hardy evergreen shrubs. Suckers. Common soil. R.androgynus is a green-house evergreen climber. Division. Rich soil.

Russelia

Four species. Store evergreen shrubs. Cuttings. Light rich soil.

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 indurated. Some think it arises from their being handled, or the hair of the head touching them; but the disease is often too general to admit of this topical explanation. I believe it to arise from an over-heating of the vinery, however unintentional, 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

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 and disgusting to good taste, 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.

Ruta

Two species. Hardy and half-hardy evergreen shrubs. Cuttings. Light rich soil. See Rue.

Ruyschia

Ruyschia clusioefolia. Stove evergreen shrub. Ripe cuttings. Loam and vegetable mould.

Ryanoea

Ryanoea speciosa. Stove evergreen shrub. Ripe cuttings. Peat and loam.

Rytidophyllum

Rytidophyllum auricula. turn. Stove evergreen shrub. Cuttings. Peat and loam.

Sabal

Five species. Stove palms. Suckers. Light loamy soil.
