Les rosiers formant ce groupe, le plus important de tous, sont des arbustes de végétation vigoureuse, très florifères et portant beaucoup à fruit. Rameaux allongés, généralement gris; aiguillons nombreux, crochus; feuillage vert foncé, folioles ovales; floraison le plus souvent en corymbe; fleur forme en coupe ou chiffonnée, frisée, quelquefois globuleuse, coloris du rouge clair au pourpre noirâtre; fruits abondants, de forme plutôt arrondie.

Hybrid Perpetuals.
Alfred K. Williams (Schwartz, 1877). — Makes long shoots as a maiden, or at times on good soil as a cutback, but the constitution is weak. Thorny, with good foliage, and will stand some rain. This is a Rose of great reputation, because the blooms nearly always come perfect, forming first-class examples of the popular "imbricated" shape, i.e. something after the form of a camellia. Not a good bloom to last, or of the largest size, but prominent as a show Rose from its shape and bright colour. It is not a very free bloomer but comes again pretty fairly in the autumn. It is quite a late Rose with me, as the shoots, though not very stout, run up to some height ; but it comes early with some growers. The plants are not hardy or long-lived, and fresh ones should be budded every year, preferably on the briar, as, though some do well as cutbacks, maidens are more to be depended on: some find it answers best as a standard. Not to be recommended for those who cannot give it good soil and high culture, but well spoken of in America and Australia. (My notes are from Philadelphia in America, and from Sydney in Australia.) Grand Mogul is said to be a seedling from this beautiful Rose.

Rose A. K. Williams.
When this Rose was sent out in 1877 by Monsieur J. Schwartz it was considered too delicate a grower to rank among any but those grown purely for exhibition. I well remember how my first half a dozen plants dwindled away during the winter of 1878-79. However, now it has got over the strain of excessive propagation, I find it is a fairly good grower and hardy. It speaks much in favour of this variety that it has reliably won the medal as being the best Hybrid Perpetual in the show oftener than any other Rose. To win this coveted honour only once among the galaxy of Roses brought together at the Crystal Palace exhibitions is no mean feat, but when we remember the occasions on which A. K. Williams has been to the front, there is little need to say it is one of the most perfect Roses of its type- imbricated. So much is this recognised, that when the National Rose Society wished to figure a variety as an example of the imbricated form, they chose this, at that time a comparatively new Rose. One of the earliest and certainly one of the very best late-flowering varieties in this extensive class, A. K. Williams also possesses the great merit of seldom producing any but perfectly finished blooms. Deep carmine-red when first opening, changing to a more or less magenta hue with age, every flowr bold and upright, with good lasting flowers and exquisite fragrance, it is indeed difficult to select a more desrving favourite among dark red Roses than the one under notice. In all Rose elections since this variety has become known it stands very close to, if not absolutely at the top of its class. Among mixed classes it is generally in the first three or four. It is not so long-lived as many when grown upon the Manetti, but its earliness when grown upon that stock, especially as a maiden, makes it well worth cultivating in this form. The Brier stock gives a more lasting bloom, and is much the best for autumnal flowering. A. K. Williams is useful for forcing, making a neat, compact plant, and carrying from three to twelve blooms at one time in a 6-inch or 8-inch pot.
