3-lobed, lobes narrow, lanceolate. Filaments membranous, united into an angular 

 tube ; anthers of a dusky blue, bearded at the apex, more especially the inferior 

 one. Style the length of the filaments ; stigma somewhat globose, surrounded by

This distinct species of Lobelia is in the collection of the Birmingham 

 Botanical and Horticultural Society, who are indebted for it to Mr. Knight, of 

 King's Road, Chelsea. 



MONOCOTYLEDONES. 

 ORCHIDACEiE § VANDEiE. 



Coryanthes maculata, vav. Parkeri. Hook. Mr. Parker's variety of 

 Coryanthes. Bot. Mag. t. 3747. This variety differs merely in having the 

 labellum marked with purple. It appears from the specimen figured to be a 

 handsome variety. It is a native of Demerara, and was imported by C. S. Parker, 

 Esq. Bot. Mag. 



Oncidium \ concolor. Hook. One-coloured Oncidium. Bot. Mag. t. 3752. 

 This is certainly a very beautiful plant, bearing a raceme of brilliant yellow 

 flowers. It is a native of the Organ Mountains of Brazil, where it was found by 

 Mr. Gardner, in the year 1837, and sent by him to the Woburn collection, the 

 property of the Duke of Bedford. Sir W. J. Hooker is doubtful whether it be 

 an Oncidium or not, and states that in some respects it agrees with Miltonia, 

 though it differs from that genus, which has an entire lip. Bot. Mag. 



Odontoglossum Rossi i. Ross's Odontoglossum. Bot. Reg. N. S. t. 48. This 

 is a pretty species, though, according to Dr. Lindley, inferior in beauty to several 

 which have been discovered before. We may hope, however, that other species 

 of this beautiful genus will soon be added to our collections, as Mr. Hartweg is 

 now actively engaged in exploring Oaxaca, a country which may be regarded as 

 the head- quarters of the tribe, and from which we shall probably derive many rich 

 and beautiful varieties. The flowers of some of the plants in this genus, besides 

 being remarkable for their colouring, frequently attain a considerable size. Indeed, 

 the Odontoglossum nebulosum produces flowers which are as much as nine inches in 

 circumference. The 0. Cervantesii resembles Rossii, but the flowers are larger, and 

 the eolours more beautiful. 



O. Rossii was found in Mexico by Mr. Barker's collector, Mr. Ross, after 

 whom it has been named. The sepals are of a dark green colour, spotted with 

 purple. The petals are white, marked also with purple. The labellum is white, 

 having a yellow claw, and the contrast of the different colours produces rather a 

 singular and beautiful appearance. 



It requires to be cultivated in a warm damp stove, where it may either be potted 

 in the usual way, or suspended from the roof on a piece of wood. It may be mul- 

 tiplied as plants of this tribe usually are. Bot. Reg.
