is a hardy perennial, increasing much by its roots, which are of the creeping kind, and by parting of which in the autumn it is most readily propagated; like the periwinkle, it is a plant well adapted to cover a bank, or bare, spots under trees, where other plants will not thrive.

It flowers from July to September.

Dais Cotinifolia. Cotinus-Leav'd Dais.

Class and Order.

Decandria Monogynia.

Generic Character.

N^o147.

The Dais cotinifolia is an ornamental Green-house Shrub, of the deciduous kind, and though it appears from the Hortus Kewensis to have been introduced by Mr. James Gordon, of Mile-End, in 1776, is yet a great rarity with us, and only to be found in some of the first collections.

Its scarcity, and consequent very high price, is attributed to the Nursery-men's not having yet discovered the means of propagating it freely.

Messrs. Grimwood and Co. of Kensington, have some very fine plants of it, which flower every year in the months of June and July, but as yet have produced no perfect seeds, which they may be expected to do when grown older; such having been known to ripen them in Holland.

It is a native of the Cape, and appears to have been long possessed by the Dutch, as its Generic Character taken from D. V. Royen, is printed in the Genera Plantarum of Linnæus in 1764.

There are only two known species, and they vary in the number of their Stamina, and divisions of the Corolla.

Pelargonium Betulinum. Birch-leav'd Crane's-Bill.

Class and Order.

Monadelphia Heptandria.

Generic Character.

N^o148.

Though long since described, we have been in possession of this species of Crane's-Bill but a few years; it is one of the many new ones introduced by Mr. Masson from the Cape, and at the same time one of the most desirable, as its blossoms which are ornamental, are freely produced during most of the summer, and the plant itself is readily propagated by cuttings.

The flowers vary considerably, both in size, and colour; its foliage is different from that of most others, and, as its name imports, like that of the Birch-Tree.

It requires the same treatment as most other Green-House Plants.

Zinnia Multiflora. Many-Flowered Zinnia.

Class and Order.

Syngenesia Polygamia Superflua.

Generic Character.

N^o149.

The Zinnia, multiflora, a native of Louisania, is a plant of more modern introduction, but requires the same treatment, and flowers at the same time, as the Tagetes patula, with which, though far inferior in brilliancy of colour, it contributes to decorate the borders of the flower-garden from June to September.

There is a variety of it with yellow flowers, nearly as common in our gardens as the present plant.

Linnæus gave to this genus the name of Zinnia, in honour of Joh. Gottfr. Zinn, the pupil of Haller, and his successor at the University of Gottingen.

The plant we have figured, answers to the name and to the specific description of Linnæus's multiflora; having never seen his pauciflora, we cannot say whether there be any just cause for suspecting them to be varieties of each other.

Tagetes Patula. Spreading Tagetes, or French Marigold.

Class and Order.

Syngenesia Polygamia Superflua.

Generic Character.

N^o150.

For richness and variety of tints few flowers can vie with this species of Tagetes, which forms one of the chief ornaments of our gardens at the close of summer.

Some authors make it a native of Africa, others of America.

Two principal varieties are usually kept in the gardens, the common small sort with a strong disagreeable smell, and a larger one here figured, usually called sweet-scented, the former is of more humble growth, its branches more spreading, its blossoms smaller than those of the latter, the flowers of which have usually a greater portion of the yellow tint, and the smell of the other so modified as to be far less
