Rosa damascena; and on the und rs de the leaf- With bud just opening, the outside petals are somewhat broadly obovate, apex roughly dentate; intermediate petals, oval, apex slightly notched; inner petals, half moon shape.

The number of petals have been variously determined as 47, 57, 73.

The blooms average 3% inches across, with fairly full center, and finally opening rather flat, showing the stamens which are many; and the filaments are red, long; anthers, broad, brownedged, yellow-centered.

The pistils also are many, stiles long, protruding from hip, stigmas large yellow. Rudimentary hip nearly round.

The bud is round, with the five sepals extend-' ing beyond it as foliaceous appendages, and six or more appendages on margins and on foliaceous tips of sepals; also a few hairs on surface and margins.

The petals are moderately thick, satiny, and drop cleanly.

The foliage is abundant, leathery; of five large oval leaflets of dark dull yellow' green, Plate XXX[I-3l-m, coarsely serrate, almost dentate, with a few prickles on under side of rachis.

The thorns are abundant, rather slender, red on young wood, gray on old wood, old wood dark brown.

The plant itself is bushy, vigorous, moderately well-branched, of strong stems, flowers usually borne singly on 5-inch to 9-inch branches, while the leaflets are rough, especially above.

The stipules are narrow, long, acute, and turned out at an angle of 45.

The new foliage and the shoots are green.

I claim:

A hybrid perpetual rose as shown and described and characterized by a yellowish copperred bud of medium size tending to globular form, and the bloom being double, of good size, possessing lasting qualities and intensely fragrant, having the odor of Rosa damascena, with the high color generally of the Austrian Copper rose except at the base and back of the petals where yellow predominates and merges into the copperred color of the bloom proper; and the foliage being abundant, of large size, more glossy than that of Rosa dam'ascevra, and of a dark green color with three, five and seven leaflets having sharper serrations than Rosa damascena, the canes of the plant being moderately thorny and of vigorous, superior growing qualities, attaining a height in excess of six feet.
