NEW AND RARE PLANTS. 17 



are various styles of Roses, each good in its way. Two points, how- 

 ever, (the habit of the plant and the form of the flower) should admit 

 of universal application. By duration of bloom, allusion is more par- 

 ticularly made to the length of time the flowers continue in perfection 

 when open, than to succession of flower. The Smithii (Yellow Noi- 

 sette), for example, and in fact most thick-petal led Roses, hold their 

 flowers in perfection for some days, whereas others fall almost as soon 

 as expanded. Now, to obtain a number of flowers on one plant, in all 

 the various stages of bloom, at a given time, is one great point the 

 cultivator of Roses in pots for exhibition has to attend to. There- 

 fore, both among summer and autumn Roses, such as are for some 

 time in perfection as buds, and when expanded for some time in per- 

 fection as flowers, are certainly the most desirable. Scent, which is 

 an estimable property of a Rose, needs no comment.

LIST OF NEW AND RARE PLANTS. 



Anemone Obtusifoma. Dr. Govan's Anemone. (Bot. Reg. 65.) Ra- 

 nunculaceae, Polyandria Polygynia. A native of Choor (Himalayan) Moun- 

 tain, where it blooms in May. It proves to be a hardy , alpine plant, growing 

 about six inches high, well suited for a rockwork, in a damp, shady situation, 

 where it blooms from June to August. The flowers are produced in. umbels of 

 five or six in each, white, a separate flower, is near an inch across. It is in the 

 collection in the garden of the Horticultural Society. 



Angulosa Clowesii, Mr. Clowes's. (Bot. Reg. 63.) Orchidaceae. Gy- 

 nandria Monandria. Mr. Linden discovered this species in Columbia. It has 

 bloomed in the collection of the Rev. John Clowes, of Broughton Hall, near 

 Manchester. A plant will throw up several strong flower-stalks, each producing 

 one flower. Each blossom is from three to four inches across, of a thick fleshy 

 substance. Sepals and petals of a pretty light yellow, labellum white, with a 

 tinge of yellow near the base. 



Armeria Cephai.otus. Large-headed Thrift. (Bot. Mag. 4128.) Plmn- 

 baginf-se. Pentandria Pentagynia. Synonvm, Statue cephalotus. This fine 

 plant was introduced into this country in 1775, but soon lost. It is a native of 

 several parts of Portugal and of Barbary. It has again been recently introduced 

 from France under different names. It is probably not quite hardy enough to 

 bear the open border in all parts of this country ; but in a cool greenhouse it is 

 a most beautiful object. The flower stems rise to from a foot to half a yard 

 high, each having a head of blossoms about three inches in diameter, of a rich 

 rose colour. It blooms from July to October, and deserves a place iu every 

 greenhouse. It may be had at the principal nurseries. 



Begonia Rcbricaui.is. Rkd-scaped. (Bot. Mag. 4131.) Begoniaceoe. 

 Monajcia Polyandria. In a former volume we gave a descriptive list of the fine 

 collection of this interesting tribe of plants which we saw in the stove at the 

 Royal Botanic Gardens at Kew, (see March, 18-13, page 63,) to which is added
