BOTANICAL NOTICES OF NEW PLANTS.

present species, that (if we exeept the colour, and the somewhat smaller leaves,) it would be 

 difficult to detect in them any points of difference, upon which to frame a specific character. 



Dendrobium Sulcatum. Lindl. Furrowed Dendrobium. Bot. Reg. N. S. t. 65. This is cer- 

 tainly a beautiful species bearing golden yellow flowers, and, according to Dr. Lindley, related to 

 D. Griffithianum, from which it differs in its three flowering peduncles, and in the form of the lip. 



It is a native of India, and was obtained by Mr. Gibson for His Grace the Duke of 

 Devonshire. 



The following important observations on its culture are given by Dr. Lindley. " At certain 

 seasons of the year," says the above distinguished author, " the plants manifest an inclination for 

 growth ; they must then have plenty of water, and be freely syringed overhead. When the 

 growing season is over, the leaves will become yellow and finally drop off ; water then must be 

 discontinued, the temperature lowered, and the plant allowed a season of rest. After remaining 

 in this state for a few weeks, the temperature may be again raised, and the plants — which by 

 this treatment will have been rendered excitable — will come freely into flower." Water need 

 not be given until the plant begins to shoot from below, when it will require the same treatment 

 as before. It must have the same soil as other orchidaceous plants. Bot. Reg. 



EPIDENDREiE. 



Cattleya Guttata var. Russelliana. Hook. Spotted Cattleya, Lord Edw. Russell's mr. 

 Bot. Mag. t. 3693. This is a very beautiful variety of Cattleya Guttata, and was brought to 

 the Wobum collection from Brazil with many other rare South American productions, in the 

 spring of 1838, by Capt. Lord Edw. Russell, R. N., then commanding her Majesty's ship 

 Actseon. It was given to that nobleman by the director of the botanic garden at Rio, with the 

 information that it was one of two specimens that had recently been discovered in the Organ 

 Mountains. 



Widely as its inflorescence differs in size and colour from Dr. Lindley's C. guttata, it cannot 

 be considered otherwise than as a beautiful and stately variety, worthy of a place in every choice 

 collection of Epiphytes. Bot. Mag. 



Epidendrum Stenopetalum ; pseudobulbis cylindraceo-oblongis ; foliis lanceolatis; flori- 

 bus solitariis ; sepalis lanceolatis ; petalis anguste linearibus labello trilobo, lobo medio cuspidato- 

 purpureo, lobis lateralibus subrotundis albidis columnam involventibus. 



This delicate and pretty species of Epidendrum is a native of Mexico, and was imported by 

 Geo. Barker, Esq., in the year 1837. Its sepals and petals are brownish, the labellum is white 

 having the upper portion tinged with purple. It appears to be a species that only produces a 

 solitary flower at a time. 



§ VANDEiE. 



Comparettia coccinea. Lindl. Scarlet Comparettia. Bot. Reg. N. S. t. 68. This is a 

 beautiful epiphyte, bearing a raceme of brilliant scarlet blossoms, mixed with golden yellow. It 

 is said to be a native of Brazil, but it agrees so completely with specimens which Dr. Lindley 

 has received from Xalapa, that he imagines there must be some mistake in its reputed country. 

 Dr. Lindley further remarks on this genus : — Nothing is more common than for orchidaceous 

 plants to produce spurs from the sepals and labellum, but it is very unusual for the same organ 

 to produce two spurs. Satyrium and Diplocentron were almost the only cases of this structure. 

 Here, however, the labellum not only has two spurs, but they are hidden within the spur of the 

 united pair of lateral sepals, so that they are not discovered till the latter is cut open. In this 

 respect we find almost the same structure for Orchidaceas as we have in Aconitum among 

 Ranunculacese. Comparettia consists at present of this and two other species inhabiting Peru. 

 Of these C. falcata approaches the present in many respects. It, however, appears to differ in 

 having broader leaves, larger flowers, no elevated plate at the base of the stigma, and the spurs 

 of the lip smooth. Bot. Reg.
