ODONTOGLOSSUM ROSSII. 



bars of rich brown. Petals white, revolute, with a few spots of brown at the base. Lip of a 

 pure, beautiful white, the claw parallel with the column, the crest formed of two elevated fleshy 

 lamellae, marked on the inner side with a few yellowish-brown streaks, connate in front, and 

 terminating in two short, obtuse teeth. The limb deflexed, and spreading nearly at right-angles 

 with the claw, ovato-rotundate, undulate, undivided. 



This handsome plant is in the collection of George Barker, Esq., who received 

 it from Mexico, where it was found by his collector, Mr. John Ross. It differs 

 in several respects from the original species, O. Mossii, as figured by Dr. Lindley 

 in the Sertum, and Botanical Register. The flowers are larger ; the sepals are 

 more acuminate, and free from the yellowish-green tint ; while the lip is undivided, 

 not emarginate. 



It requires the hot and humid stove during the growing season ; but should be 

 kept more cool and dry when at rest. The soil should be rough sandy peat, 

 mixed with small drainers. It may be increased by division of the pseudo-bulbs.
