 and under a bell glass. (Pcut. Mag. of Bot., June.)

A nearly hardy perennial, requiring a dry situation, and " about the same 

 treatment as Acanthus mollis." It should be protected from wet in winter 

 by a hand-glass. " It is increased freely from seeds, and flowers from July 

 till late in autumn. The stem is covered with soft hairs, which, when bruised, 

 emit the smell of a geranium." (^Bot. Reg., June.)

Tanacetum longifdlium Wall. A " weedy plant from the Himalayas." It 

 grows about 2 ft. high, with light green finely cut leaves, and a rayless head 

 of yellow flowers. {B. M. R., No. 78., June.)

Volemonium ccBrideiim var. grandifdlium Lindl. An Indian variety of this 

 well-known plant, with flowers three times as large as those of the common

Orthosiphon is one of the genera separated by Mr. Bentham from the old 

 genus O'cymum, as Coleus is another. The species has pretty pink flowers, 

 disposed in racemes of from 6 in. to 1 ft. long ; and it is kept in the stove. 

 It is a native of the hills of Sylhet, and it was sent from the botanic garden 

 at Calcutta, by Dr. Wallich, to the Duke of Northumberland, and it flowered 

 in His Grace's collection at Syon.

Qiiercus regia Lindl. The general appearance of this oak resembles that 

 of a Spanish chestnut. Its leaves are dark green and shining, heart-shaped 

 at the base, and frequently 9 in. long, and 3 in. broad. " The leaf-stalks are 

 almost J of an inch long. It probably belongs to the same section of the 

 genus as Q. rigida." {B. M. R., No. 73., June.) ^ 



Q. Brantn Lindl. Apparently allied to Q. Ballota, but with the leaves 

 6 in. long, including the petiole, and 3^ in. across the widest part ; " they are 

 as downy as those of a young plum tree." This species has been named in 

 honour of Mr. Brant, who discovered it. (5. M. R., No. 74., June.)

This curious epiphyte was one of the very few found by Mr. Gardner in 



the interior of Brazil. Its general appearance is somewhat like that of a 



Catasetum, but it is characterised by the singular formation of its labellum, 



" the margins of which are beautifully fringed with white, flexuose, succulent 



hairs, greenish white beneath, dotted with red, bearing on the upper side at 



the base an erect three-partite spine or horn, and having a much larger por- 



rected one below the acumen, which is a little toothed or fimbriated." {Bot. 



Mag., June.)

A very beautiful species of this extensive genus ; nearly allied to O. car- 

 thaginense, but with smaller flowers, " much more beautifully marked and 

 coloured, and the lip has a totally different structure." {Bot. Mag., June.)

A pretty orchideous plant, nearly allied to Maxillaria. In order to culti- 

 vate it " successfully, it should be suspended upon a block of wood from the 

 rafters of the stove, and its thick fleshy roots allowed to hang in the air, and
