ROSA LUTEA.

GROUP XV.-THE AUSTRIAN BRIER.

This may be called a group of Yellow Roses, for the varieties which compose it are mostly of that colour. The Austrian Brier is a native of Germany and the south of France, and was introduced to England in 1596. It is distinguished by its small leaflets and solitary flowers, the bark of the wood being, for the most part, of a chocolate colour. The varieties are very hardy, but require a pure air and dry soil to flower them in perfection. Hence, they rarely succeed well near London; the Harrisonii is an exception, and the Persian Yellow may be the same; but of this we have as yet no proof. I have been told that the latter variety grows wild in the hedges of Persia. If so, strange it is that a Rose of such rare beauty should only just now have reached Europe. But probably it was the single kind which caught the eye of my informant.

The Harrisonii is capable of being formed into a perfect Weeping Rose. Select a plant on a four-feet stem, grow it vigorously, thinning out, but not shortening the shoots. Thus it will droop beautifully, producing its golden blossoms in gorgeous abundance. If a Weeping Rose is wanted every year, two plants should be grown, that each may be cut in close every alternate year, otherwise the tree becomes weak and shabby.

These Roses require very little pruning: the flowers are usually produced from the eyes at the middle or near the top of the shoots: the branches should, therefore, be well thinned out in ordinary pruning, the shoots left having their mere tips taken off.

1. BICOLOR, OF FLAMED; flowers copper and yellow, single; form, cupped. Habit, branching; growth, vigorous.

2. COPPER; flowers rich reddish copper, single; form, cupped. Habit, branching; growth, moderate.

3. DOUBLE BLUSH; flowers light rosy pink, their centre buff; form, cupped. (Victoria) Very sweet.

4. DOUBLE YELLOW, (Williams'); flowers bright yellow, of medium size, double; form, cupped. Habit, branching; growth, moderate. An abundant and early bloomer; requiring but little pruning. A good seedbearer. Raised by Mr Williams of Pitmaston.

5. GLOBE YELLOW; flowers bright lemon; form, globular.

6. HARRISONII; flowers fine golden yellow, of medium size, double; form,

cupped. Habit, pendulous; growth, moderate. An abundant and early bloomer, producing a splendid effect on the tree, but very transitory. Requires little pruning. Introduced from America about fourteen years since.

7. HARRISONII, No. 2; flowers buff, their centre reddish salmon; form, cupped. 8. ITALIAN YELLOW; flowers pale straw colour.

9. PERSIAN YELLOW; flowers of the deepest yellow, large and full; form, globular. Habit, branching; growth varies, often vigorous. Requires

but little pruning. Introduced from Persia by Sir H. Willock in 1837.

VICTORIA; see Double Blush.

ROSA ARVENSIS.

GROUP XVI.-THE AYRSHIRE ROSE.

This is a native species, abounding also throughout Europe, trailing over waste lands, and climbing the hedges and thickets, often completely hiding the undergrowth from view, producing its solitary blossoms in magnificent profusion in June and July. This is the hardiest of Climbing Roses, growing exceedingly rapid where others will scarcely exist. The shoots are slender, owing to which the varieties form admirable Weeping Roses when worked on tall stems: they are also of the best description for planting to cover banks, and rough places in parks or shrubberies, soon converting the dreary waste into a flowery plain. "Ruga," one of the best of the Group, is apparently a Hybrid between the Ayrshire and Tea-scented. It was raised in Italy, and is quite hardy, notwithstanding the proverbial delicacy of the one parent.

As may be supposed from the names of these Roses, they are chiefly of British origin; indeed, we scarcely find mention of them in foreign Catalogues. 1. ALICE GRAY; flowers creamy salmon blush.

2. ANGLE; flesh tinged with rose, large and semi-double; form, expanded. (Jessica)

3. BENNETT'S SEEDLING; flowers white, of medium size, double; form, ex(Thoresbyana) panded. A free bloomer.

THORESEYANA; see Bennett's Seedling.

ROSA SEMPERVIRENS.

GROUP XVII.-THE EVERGREEN ROSE.

The Sempervirens Rose abounds throughout the middle of Europe, and is supposed to have been introduced in 1629. It is suited for the same purposes as the Ayrshire, from which it differs by producing its flowers in corymbs, instead of singly, and by holding its beautiful dark green leaves till the depth of winter. On account of these properties, we think it more valuable than the last mentioned. It is not strictly evergreen, as its name would lead us to suppose. It is very hardy, of vigorous growth, and an abundant bloomer. As Pillar Roses some are very beautiful, rising quickly to the height of ten or twelve feet, their pretty ranunculus-shaped flowers drooping in graceful corymbs of from ten to fifty blooms each. In pruning they require much thinning, and the shoots left should be merely tipped.

1. ALBA PLENA; flowers pure white, full.

2. ADELAIDE D'ORLEANS; flowers creamy white, of medium size, full; form, (Leopoldine d'Orleans) globular. Blooms in large handsome clusters. Α
