border ; the flowers are produced in spikes of six or eight inches long, thej 

 are of a deep orange colour, having a purplish red calyx, the contrast o$ 

 which is very pretty, each blossom is about half an inch long; the plant 

 blooms very freely, and the blossoms being of a bright colour produce a • 

 pretty effect. It has bloomed in the collection of J. D. Llewellyn, Esq. 



5. RUELLIA CIL1AT1FLORA. Fringe flowered Ruellia. (But. Mag. 



ACANTHACEA. DIDYNAM1A ANGIOSPERMI A. 



This is rather an ornamental stove plant, with oblong serrated foliage, and 

 flowers produced upon a short pannicle, which are of a purple colour, having 

 five cordate petals, and a spreading disk. It was sent home by Mr. Tweedie, 

 and is supposed to be a native of the interior of Mexico. 



6. P1MELEA HENDERSONI. Mr. Henderson's Pimelea. (Bot. Reg. 



THYMELEA DIANDRIA MONOGYNIA. 



Is a very pretty plant, intermediate between P. decussata and P. rosea?. 

 It is a native of King George's Sound, and was raised from seeds received 

 from thence by Messrs. Eagle and Henderson. This is said to be one of the 

 most ornamental of the genus ; and judging from tLe plate, we are fully in- 

 clined to fall in with this opinion. The colour of the flowers is a light rose. 

 The branches are very thickly set with leaves. 



7. BRASSAVOLA CUSPIDATA. Spear-lipped Brassavola. (Bot. Reg. 



ORCHIDES. GYNANDRIA MONANDRIA. 



This is a native of Trinidad, imported from thence by John Moss, Esq., of 

 Otterspool, Liverpool. We are here told, that owing to the skill of this gen- 

 tleman's gardener, and the extensive connexions wbich Mr. Moss, possesses 

 abroad, his collection at Otterspool bids fair to *i.al some of the many col- 

 lections of orchidaceous plants, of which the country may well be proud. 

 Five species of this genus have already been described by Professor Lindley, 

 of which the one now under consideration is the sixth, and nearly related to 

 B. cucullata. 



To those unacquainted with the genus as well as the species referred to, 

 it may be well to say that the B. cuspidatahas long ridged rush-like foliage, 

 bearing a few scattered white flowers. 



8. DENDROBIUM FORMOSUM. Beautiful Dendrobium. (Pax. Mag. 



ORCHir>E.€. GYNANDR1A MONANDRIA. 



Amongst the genera of orchidaceous Epiphytes none contains a greater 

 number of really beautiful species than Dendrobium, of which we think it 

 quite just to the genus to say, the species now before us is decidedly the 

 most ornamental. The foliage is scanty, being only a pair or so on the sum- 

 mit of a rather tall fleshy stem. The ttowers are very large, and nearly 

 white. We are told that this handsome plant was discovered in a district 

 called Pondooah, at the base of the Khoseea Hills, by Mr. J. Gibson, collect- 

 or to his Grace the D'ike of Devonshire, and under whose care it produced 

 its handsome flowers at Chatsworth. during the spring of 1S38. Some excel- 

 lent directions are here given on the cultivation of this genus, the most 

 important of which are those which refer to a season of rest or the suspension 

 of moisture, but not of heat. In their native localities they bloom in the dry 

 season. This period should commence about the beginning of our winter, 

 and continue tor one or two months. During this time the foliage will 

 wither, and not unt'renuently drop off, but, at the end of this period, mois- 

 ture should again be freely supplied, when the flowers and foliage will be 

 most luxuriant.
