R. SETIGERA.--Of the North American Roses none has proved more useful in this country than the Prairie Rose. A rambler in habit, it is valuable for its vigorous growth and late flowering. The flowers are large, deep rose, and appear in July and August.
R. SPINOSISSIMA (R. PIMPINELLIFOLIA).--The Scotch Rose is one of the earliest species to bloom; it is also one of the prettiest and most distinct. The stems are dwarf and covered with bristles, the leaves small, and the flower white and cup-shaped. There are several wild varieties of it, the two most noteworthy being _altaica_ (or _grandiflora_) and _hispida_. Both these grow 6 feet or more high, and the flowers of both are larger than the typical Scotch Rose. Those of _altaica_ are creamy white; those of _hispida_ a lovely cream yellow. The garden varieties of this Rose are numerous--some double, some single, and varying in colour from yellow to white and from pink to purple. The type is found wild in several parts of Britain.
R. WEBBIANA.--Coming from some of the highest elevations on the Himalaya at which shrubby vegetation exists, this species is the hardiest of the Indian Roses. It has a thin, graceful habit, and its spiny stems are blue white when young. This year it has been very pretty in the unusual profusion of its bluish-tinted flowers, each of which are about 2 inches across. The leaves are of a blue green, and are similar in size and division to those of the Scotch Roses. But it is quite distinct from them or any others, for which reason it is worth the notice of lovers of these wild types.
R. WICHURAIANA.--It is not many years since this Japanese Rose was first introduced, but it is now fairly well known. It is a perfectly prostrate plant, and is remarkable for the shiny, varnished appearance of the leaves. It is one of the latest species to come into bloom. The flowers are pure white, and appear during July and August in clusters resting on the carpet of glossy foliage. It makes an excellent covering for sunny banks where the soil is good. Old tree stumps are also pretty when covered with this Rose. It has already been hybridised, and among its progeny are Pink Roamer, Manda's Triumph, South Orange Perfection, and Jersey Beauty. There is a very distinct cross between it and _R. rugosa_ at Kew.
