20 Rosa Jacksoni Hort. (Rosa rugosa x wichuraiana)
Rosa Jacksoni : caulibus brevibus, arcuatis ; aculeis inaequalibus, haud densis, rectis, gracilibus ; foliolis 7-9, oblongis, obtusis, firmis, glabris, late breviter simpliciter serratis ; rhachi aciculata, haud glandulosa ; stipulis adnatis, apicibus liberis ovatis ; floribus pluribus, corymbosis ; pedicellis leviter aciculatis; calycis tubo globoso, leviter aciculato ; lobis ovato-lanceolatis, apicibus elongatis, dorso leviter glandulosis ; petalis magnis, rubris ; stylis liberis, haud prompts ; fructu globoso, rubro.

Stem low, arching; prickles very unequal, not dense, straight, slender, the largest 1/4 in. long. Leaflets 7-9, oblong, obtuse, firm, glabrous or nearly so, openly shallow simply serrated; petioles aciculate, not glandular; stipules adnate, with ovate free tips. Flowers seceral, corymbose; pedicels slightly aciculate. Calyx-tube globose, slightly aciculate; lobes ovate-lanceolate, with Long leafy tips, slightly glandular on the back. Petals large, bright crimson. Styles free, not protruded beyond the disk. Fruit urceolate-globose or ampullaeform, bright red, much smaller than in Rosa rugosa.

Rosa Jacksoni is one of the numerous hybrids to which These two roses (Rosa Wichuraiana and Rosa rugosa) have given rise. It was raised at the Arnold Arboretum by Mr. Jackson Dawson, and was sent from thence to Kew in 1897; it is thus one of the earliest of the Wichuraiana hybrids. It is exactly intermediate between its parents, and is of graceful habit and good constitution, often making shoots seven to eight feet long in one season. It is extremely floriferous and is in every way an acquisition to a garden,

A new Rose. — Mr. Jackson Dawson, of the Arnold Arboretum, has produced from a cross between Rosa rugosa and R. Wichuriana a Rose which trails flat on the ground, with very thorny wood like rugosa, and with rugosa foliage in form and colour, with all the gloss of Wichuriana and flowers 3 inches across, of a fine light red. It is sure to be very useful in many situations. This is, I think, the first time it has been described. I consider it the most interesting Rose raised in this country for some time.
