NEW AND RARE PLANTS. 217 



gases and vapours of the atmosphere is rapidly to permeate each 

 other's bulks, and become equally diffused ; and on this principle, 

 and from his experience with the plant-cases, he concludes that the 

 noxious gases, in all ordinary cases, have little or no influence in de- 

 teriorating the atmosphere either for plants or animals. 



The admirable manner in which the plants grow, the beauty and 

 neatness of appearance, strongly recommend them for every good 

 aspected sitting room. I purpose sending, for a future Number, a list 

 of the plants grown in the several cases in the possession of my friends, 

 and remarks thereon. I have above given a list of some genera 

 growing in a case ; it is at the habitation where I am but a lodger ; 

 when, however, I am master of a house, I purpose having one of Ward's 

 glass cases.

 LIST OF NEW AND RARE PLANTS. 



Acacia dentifeha. Tooth-bearing. (Bot. Mag. 4032.) Leguminosae. 

 Polygamia monaecia. Mr. Drummoncl discovered it at the Swan River colony, 

 and sent seeds of it, we believe, to the Glasgow Botanic Garden. The plant 

 which was raised is now seven feet high ; it blooms most profusely. The ra- 

 cemes of flowers are very large, drooping, each being about six inches loner, 

 having from thirty to forty blossoms of a rich yellow, and very highly fragraift. 

 Several of these racemes are produced at the ends of the branches, making a 

 splendid show. The leaves are about six inches long, and a quarter of an inch 

 broad. The plant blooms from March to May, and deserves a place in every 

 greenhouse or conservatory ; as it blooms when even a small plant, it can be 

 grown to accommodate either situation. 



Clowesia rosea. Pink-flowered. (Bot. Reg. 39.) Orchidaceae. Gynandria 

 monandria. A native of Brazil. The flower stems rise to about three or four 

 inches long, producing five or six erect delicate white flowers tinged with pink. 

 The edges ot the petals and end of the lip are beautifully fringed. It is a very 

 interesting flowering plant, of the catasetum division, and has bloomed in the 

 collection of the Rev. J. Clowes of Broughton Hall, near Manchester. 



Census Weldenii. Dalmatian Laburnam. (Bot. Res'. 40.) Leguminosae. 

 Diadelphia decandria. A hardy bush, growing ten feet high ; the flowers are 

 produced in short erect racemes, of a bright yellow colour. It is more poisonous 

 than the common Laburnam, even the scent of the flowers produce head-ache. 



Eranthemum montanum. Mountain eranthemum. (Bot. Mag. 4031.) 

 Acanthaceae. Diandria monogynia. (Synonym, Justicia montana.) A native 

 of the Sicar mountains, Ceylon, &c. It is a stove shrub, blooming profusely in 

 spring. The flowers are produced in branching terminal spikes ot twenty blos- 

 soms on each. The tubular portion of the flower is two inches long, greenish- 

 yellow. The limb (face of the flower) is divided into five lobes, about an inch 

 and a quarter across, of a pretty lilac-purple, spotted with red at the entrance of 

 the tube. It is a very pretty flowering plant, well deserving a place in the 

 stove. 



Laeichea punctata. Two-pointed leaved. (Pax. Mag. Bot.) Legumi- 

 nosae. Diandria monogynia. A native of the Swan River colony, from whence
