ORIGINAL COMMUNICATIONS.

ART. I. Report on the new Species and Varieties of Hardy Trees and Shrubs raised in the Horticultural Society's Gardens since the last Report, made in October, 1838, and published in the "Gardener's Magazine," vol. xiv. p. 581. Drawn up for the "Gardener's Magazine" by Mr. GORDON, Foreman of the Arboretum, by Permission of the Council of the Horticultural Society.

RANUNCULA CEE.-Clématis gràta Wall. This species was raised from Himalayan seeds presented to the Society by Dr. Royle; it is quite hardy, and a free grower, flowering in October. The flowers are small, like those of C. virginiana, to which it seems nearly related, but with much smaller leaves. It was received by the Society under the name of C. nepalénsis, but upon flowering it proved to be C. gràta of Dr. Wallich; C. nepalénsis being one of those species which, like C. montàna Wall., flower in May. It is not yet introduced.

It is

Clématis [cirrhòsa] polymorpha Lodd. This is, I think, only a large, but very distinct, variety of C'lématis calycìna Ait., with large spotted flowers, and foliage double the size. probably the true Clématis balearica of Persoon, as one of the plants in the Society's collection was received from the Hon. W. Fox Strangways as the true C. balearica. The specific name baleárica is often applied to C. flámmula rotundifolia, which is the same as C. fràgrans, the subevergreen variety of C. flámmula.

Clématis Hendersònii Chandler. This beautiful hardy creeper should be in every collection, and trained on every suburban cottage, for it is one of the most ornamental of the genus, with large bright purple flowers, which are produced in profusion from June to September. It appears as if it had been raised between C. integrifòlia and C. Viticélla, but it is decidedly ligneous. It was raised by Mr. J. A. Henderson, F.H.S., Pine-apple Place. The plants in the Society's collection were presented by Messrs. Chandler and Mr. Henderson.

Clématis [campaniflòra] parviflora Dec. The Society is indebted to the late M. Fischer of Göttingen for this? species. It is very nearly related to C. campaniflòra Arb. Brit. p. 242., VOL. XVI. No. 118.

B

but has flowers only one half the size, and the plant is of slenderer growth; but the colour of the flowers and the plant in other respects is nearly the same, and it is probably only a variety of C. campaniflòra.

The following prove to be the same as Clématis campaniflòra Arb. Brit., viz. C. viornöìdes Schrader and C. Viticélla baccata Dec.

BERBERA CEE.- Bérberis [? ibérica] glaúca Booth. This is a distinct but rather slender plant, with small but very glaucous leaves, and is nearly related to B. ibérica. It was received from Messrs. Booth of Hamburg, but it is in other collections under the false name of B. ilicifòlia; but the true B. ilicifòlia of Forst. is the same as the B. heterophylla of Juss., a plant found near the Straits of Magellan, while the present plant is probably from the Altai or Caucasus.

Bérberis caroliniana Nutt. This is only a variety of B. canadensis (or rather of B. vulgàris), with long narrow leaves; and, as a variety of the common berberry, is very distinct and rather singular.

Bérberis [vulgaris] provincialis Schrader. This ? species has dark brown shoots, with few spines, red fruit, and rather shining leaves, which are retained longer than on most of the varieties of B. vulgàris. It seems as if it were intermediate between B. vulgàris and B. sinensis, and it is probably only a rather distinct variety of B. vulgàris. The plant was received from the late M. Fischer of Göttingen, as the true B. provincialis; that generally sold in nurseries for B. provinciàlis not being different from B. vulgaris.

Bérberis [vulgaris] lucida Schrader. This is only the common Bérberis vulgaris, with rather larger and brighter leaves.

Bérberis [vulgaris] emarginata Willd., Arb. Brt. p. 303. This is only a rather strong-growing variety of B. vulgàris, but not very distinct. It was received from M. Fischer of Göttingen.

Bérberis [vulgaris] spathulata Schrader. This also is only a very slight variety of B. vulgàris.

ACERA CEE.Acer [eriocárpa] Pàvia Booth. This is only a variety of A. eriocárpa, with the leaves a little more divided, and the upper surface wrinkled like some of the pavias, which I suppose induced Messrs. Booth to give this variety of (Sir Charles Wager's) maple so absurd a name.

Acer [campéstre] taúrica Dr. Fischer. This seems to be one of the endless varieties of Acer campéstre, with less divided and larger leaves, but decidedly only a variety of the common maple. RHAMNA CEE. Ceanothus thyrsiflorus Lindl. This handsome species is very distinct from C. azùreus. It has much smaller and rounder leaves, and rather flat panicles of bright blue flowers. It is the C. ovàtus cyaneus of the Continental col

lections, and was presented to the Society by Messrs. Booth and Messrs. Baumann.

LEGUMINO'SE.-Sophòra heptaphylla Bentham. A smallflowering species, probably from China, which has proved quite hardy, but of little beauty. It flowers in October.

Genista tinctòria flore plèno. This pretty double-flowered variety of the common dyer's broom was received from Messrs. Young of Epsom.

Eysenhardtia amorphöides Lindl., Bot. Reg. Miscell. 55. 1839, H. et B., vol. vi. t. 592., Don's Mill. vol. ii. p. 234. A very curious and ornamental plant raised from Mexican seeds, presented to the Society by G. F. Dickson, Esq., F.H.S. It is hardy, and resembles a small-leaved species of Amórpha, with numerous spikes of small flowers.

ROSA CEE. fòlia Don.

Spira'a adiantifòlia is the same as S. vaccinii

Spira a laxiflora Lindl., Bot. Reg. Miscell. 89. 1839. This species very much resembles in foliage and habit S. vacciniifòlia Dec., but has rather large loose panicles of white flowers. was raised in the garden of the Society, from seeds, presented by the Hon. East India Company, from the North of India.

It

Spira a cuneifolia Wall., Bot. Reg. Miscell. 87. 1839. This is the same as those sold in the nurseries about London under the following names:-S. argéntea, S. nùtans, and S. canéscens. The first name (argentea) belongs to a plant from New Granada, H. et B. vol. vi. t. 562., not yet introduced; the others are names applied by different authors. S. cuneifolia is quite hardy, and is a native of the North of India.

Spira a Lindleyàna Wall. This fine species belongs to the section Sorbària, with large pinnate and finely serrated leaves. It is very hardy, and a great addition to this beautiful family of shrubs. Raised in the garden of the Society, from seeds received from Dr. Royle.

Crataegus [spathulata] geórgica Lodd. (not of Douglas). This is certainly distinct from C. microcarpa Lindl., which is C. spathulàta Arb. Brit., but nothing more than a variety of that species, with the leaves five-lobed, on longer footstalks, and rather smaller, while those of C. microcárpa are mostly three-lobed, and broader. C. microcárpa and this variety were the only Cratæ'gi killed in the Society's very extensive collection by the winter of 1837-8.

Crataegus pectinata of some collections is the same as C. coccínea corallina Arb. Brit.

Crataegus fúsca Jacq. Plants were raised from seeds received from Baron Jacquin, under the above name; they have large prominent buds and cut leaves, like C. nigra or C. purpurea. Cotoneaster [(r) buxifòlia] marginata Lindl. This pretty plant

comes nearest to C. buxifòlia, with rather larger leaves, which are covered thickly on the under side and margin with a dense white tomentum. It was raised in the garden from seeds, sent to the Society by Dr. Falconer, from the Saharunpore Botanic Garden.

Cotoneaster denticulata H. et B. vol. vi. t. 556. This distinct species was raised from seeds collected by M. Hartweg, the Society's collector in Mexico; and, as the Society has distributed a large quantity of the seeds to the Fellows of the Society, it will soon become common. It is probably not so hardy as the other species of Cotoneaster, not one of which was killed by the winter of 1837-8 in the Society's garden.

PHILADELPHA CEA.- Deutzia corymbòsa Lindl., Bot. Reg. Miscell. No. 49. 1839. This I mentioned in my report of last year (Vol. XIV. p. 582.) under the name of D. canéscens Sieboldt; but, when the plants flowered in the Society's collection, they proved to be the same as D. corymbòsa Royle, figured in Royle's Illustrations, plate 46. fig. 2.

GROSSULA CEAE.- Ribes [Grossulària] himalayànuum Royle. This was raised from seeds presented to the Society by Dr. Royle, and seems hardly different from the R. Grossulària.

SAXIFRA GEE.- Hydrangea altíssima Wall. This curious species was raised in the garden of the Society, from seeds sent by Dr. Falconer, the superintendant of the Hon. E. I. Comp. Botanic Garden at Saharunpore; but the plants are too small at present for me to say more than to record its introduction.

CAPRIFOLIA CEE§ LONICE`REE.-Lonicera Ledeboúrii Eschsch. This very distinct species comes nearest to the L. involucrata, but is quite distinct; it has much smaller leaves, and yellower flowers. The plant was received from Messrs. Booth.

Caprifolium (sempervirens) Brównii. This is a fine variety of the trumpet honeysuckle raised by Messrs. Brown of Slough, and which, I think, should bear their name, as indicating the place of its origin. It has larger and rather brighter flowers than the common one, and, as a variety, is a great acquisition.

ERICA CEE. - Andrómeda Drummondii? Hooker. This distinct species was given to the Society by Mr. J. Cunningham of Edinburgh. It is rather a slender-growing plant, with the young leaves covered, as well as the young shoots, with a scurf like those of an Elæágnus.

Arbutus speciosa Dickson. This beautiful species has long, lanceolate, finely serrated leaves, glaucous on the under side, and bright green on the upper. It will probably form a large bush, or small tree. It was raised in the garden of the Society, from seeds, presented by G. F. Dickson, Esq. F.H.S., collected in Mexico.

Pernéttya Cummingii Lodd. This is nearly related to P.
