This, and the preceding varieties, are highly ornamental, from their fine, large, bright yellow flowers, which are produced in abundance; and their smooth, glossy, yellowish green leaves. The plants are, also, most truly ligneous, and of greater duration, than those of most other species of Ribes. Next to R. sanguineum, and its varie
ties, they merit a place in every collection.

In habit, this species is more erect than R. aúreum, and has the young wood more thinly clothed with leaves; its whole appearance is also paler, during the early part of the season. The flowers are not more than half the size of R. aureum; and have entire, not notched, petals. The fruit is about the size of the red currant, of an agreeable Aavour but possessing little acidity.

App. i. A Classification of the Species and Varieties of Ribes in the Horticultural Society's Garden in 1836, made by Mr. Gordon, Foreman of the Arboretum there.
In the following synopsis, the authorities put immediately after the names of the plants are those of the nurserymen, or others, who sent the plants with these names to the Horticultural Society's Garden ; the authorities in parenthesis are references to books; and the references to figures are those in our own pages. In short, we have here followed the plan which we adopted under Cratæ gus, in giving Mr. Gordon's arrangement of that genus ; and for the same reasons as those there given. (See p. 816.)

OF THE HARDY OR HALF-HARDY LIGNEOUS PLANTS OF THE ORDER
ESCALLONIA CEÆ. There is only one perfectly hardy genus belonging to this order ; viz. I'tea; and the principal genus, which is half-hardy, is Escallònia. Both are highly ornamentai shrubs; the former indigenous to North America, and the latter to Chili, and other parts of South America.
I'TEA L. The Itea. Lin. Syst. Pentándria Monogynia. Identification. Lin. Gen., 275.; Dec. Prod., 4. p. 6.; Don's Mill., 3. p. 596. Synonymes. Cedrela Lour. ; Diconángia Michr. Derivation. Itea is the Greek name of the willow, which is given to this genus on account of the
quick growth of the I'tea virginica. Gen. Char. Calyx bell-shaped, with 5 teeth, persistent. Petals 5, their
æstivation valvate. Stamens 5, shorter than the petals. Both petals and stamens inserted upon the tube of the calyx. Teeth of calyx, petals, and stamens, alternate with one another. Ovary not connate with the calyx. Style, at first, seemingly one; afterwards it parts into two portions: hence, there are rather 2 styles connate. Stigmas capitate, mostly divided by a furrow. Carpels two, connate into a capsule of 2 cells, that has 2 furrows, and parts from bottom to top. Seeds in two rows along the introflexed margins of the carpels. (Dec. Prod., iv. p. 6.)- A shrub, with simple alternate leaves, and flowers in racemes.

745 Racemes simple, terminal. (Don's Mill., iii. p. 196.) A deciduous shrub, growing to the height of 6 ft. or 7 ft.
A native of North America, from Pennsylvania to Carolina; introduced in 1744; and producing its white flowers, in terminal racemes, from June to August. It may be propagated by cuttings, but more readily by layers, suckers, or seeds; and it thrives best in a sandy or peaty soil, kept moist. The plant, to be kept in vigour, should have the old wood frequently cut down to the ground. When grown in a situation that is rather moist, its flowers make a fine appearance, at a season when there are few other shrubs in blossom. It is most frequently propagated by seeds, which are annually received from America. The price of plants, in the London nurseries, is 1s. each, and of seeds, 6d. a packet; at Bollwyller, plants are 2 francs cach ; and at New York, 25 cents.
ESCALLO'NIA Mutis. Tue EscalLONIA. Lin. Syst. Pentándria
Monogynia. Identification. Mutis in Lin. fil. Supp., t. 21. ; Dec. Prod., 4. p. 2.; Don's Mill., 8. p. 192. Synonyme. Stereóxylon Ruiz et Pav. Fl. Per. Prod., p. 38. Derivation. From Escallon, the pupil and companion of Mutis, during his travels in New Spain. Gen. Char., 8c. Tube of the calyx semiglobose, adnate to the ovarium ;
limb 5-toothed or 5-lobed. Petals 5, arising from the calyx. Stamens 5; anthers ovate-oblong. Stigma peltate. Style filiform, permanent. Capsule baccate. Seeds numerous. (Don's Miit., iii. p. 192.) - Subevergreen half-hardy shrubs, natives of South America, and more especially of Chili, with the leaves full of resinous glands. Propagated with the greatest ease by cuttings; and growing freely in common garden soil.
. E. rubra Pers. (Hook. Bot. Mag., t. 2890., and 746 our fig. 746.), Stereóxylon rùbrum Ruiz et Pav., is a smoothish evergreen shrub, with numerous, twiggy, rounded branches, which, when young, are clothed with glandular hairs. The leaves are obovate-oblong, acuminated, serrated, and, in their native country, full of resinous dots beneath. A tuft of young leaves springs from the axil of each of the older ones, indicative of numerous branches. The peduncles are 2–7Aowered. Lobes of the calyx denticulated. Petals spathulate, red, conniving, but spreading a little at the apex. A native of Chili
, on the mountains of Colocolo, in the fissures of rocks, and about Valparaiso. It was introduced in 1827. When trained against a wall, it grows to the height of 6 ft. or 8 ft.; flowering from July to September. It is readily propagated by cuttings, planted in sandy soil, under a hand-glass; and the plants, when placed against a wall, require no protection whatever during winter. In the Bot. Misc., iii. p. 252., three forms of this species are recorded :
E. r. 1 glabriúscula Hook. et Arn., with glandular branches, leaves highly pubescent, and red flowers, which may be considered as the species.
E. r. 2 albiflora Hook. et Arn. ; E. glandulosa Bot. Cab., t. 291. ; with white flowers.
There are plants of these varieties at Kew, the Horticultural Society's Garden, Messrs. Loddiges's, in the Goldworth Arboretum, and in the Addlestone Nursery, which have stood out as bushes in the open garden, for several years, without the slightest protection during winter.
. E, montevidensis Dec. Prod., iv. p. 4.; E. floribunda var. B montevidensis Schlecht.; E. bífida Link et Otto Abbild., t. 23., Bot. Reg., t. 1467.; and our fig. 747.; is a smooth shrub, with white flowers, very like those of the hawthorn, which are produced in great abundance from July to September. It is a native of Brazil, on sandy banks and pastures; and was introduced in 1827. It forms a remark
747 ably vigorous-growing bush, with long, flexible, rope-like shoots, and is very prolific in flowers. It is so hardy as to have stood through several winters, as a bush, in the open ground of the Kensington Nursery; so that we might almost have been justified in placing it among the hardy shrubs.
E. floribunda H. B. et Kunth is a native of New Granada, on the Andes, with white flowers, and shining leaves, which are clammy when young. The plant of this name, in the British gardens, appears to be only a variety of the preceding species.
E. resinosa Pers., Stereoxylon resinòsum Ruiz et Pav., is a glabrous shrub, a native of Peru, on the cold parts of hills. A plant of this species has stood against a south wall, in the Kew Gardens, since 1832.
• E. pulverulénta Pers., Stereóxylon pulverulentum Ruiz et Pav., is a shrub, hairy in every part, with white flowers; growing to the height of 8 ft. or 10 ft. It is a native of Chili; and plants of it have been in the Horticultural Society's Garden since 1831.
Twenty other species are described in Don's Miller., iii. p. 193. to p. 195., all natives of South America, and probably as hardy as those above mentioned ; but it does not appear that any of them have been introduced.
OF THE HARDY AND HALF-HARDY LIGNEOUS PLANTS OF THE
ORDER SAXIFRAGEÆ, TRIBE HYDRA'NGEÆ.
The only woody plants contained in this order are included in the tribe Hydrángeæ, which contains the well-known green-house, or rather coldframe, plant, Hydrangea Hortensia, that may be considered as half-hardy; and some species, natives of North America, which are quite hardy. There are also some half-hardy species, natives of Asia. They are all easily propagated by cuttings, and will grow freely in any soil that is rather moist.

dite and fertile. Tube of calyx hemispherical, 10-ribbed, rather truncate, adnate to the ovarium; limb permanent, 5-toothed. Petals 5, regular. Stamens 10. Styles 2, distinct. Capsule 2-celled, with introflexed valves, crowned by the teeth of the calyx and styles, flattish at the top, opening by a hole between the styles. Seeds numerous, reticulated. (Don's Mill., iii. p. 232.)—Shrubs, with opposite leaves. Flowers corymbose, pink, or yellowish white; the marginal ones sterile, and large, in consequence of the teeth of the calyx being dilated into broad, petal-likecoloured segments; the rest of the sterile flower having the other parts partially abortive.
