pretty and useful. The beautiful and distinct hybrid 

 M. Bleuana and its variety nobilior, which was obtained 

 by crossing M. vexillaria and M. Roezlii, is a splendid 

 addition to the family. M. vexillaria succeeds in well- 

 drained peat and sphagnum moss, and, having numerous 

 fibrous roots that ramble over and through the surface of 

 the compost, it should have sufficient pot room for their 

 extension. The plants may be repotted in August to 

 February. 



Moorea 



This is a new genus founded by Mr Rolfe, of the 

 Royal Gardens, Kew, and its one species is named 

 Moorea irrorata, being worthily dedicated to Mr Moore, 

 Curator of the Royal Botanic Gardens, Glasnevin. 

 It is closely allied to Houlletia. The only two plants 

 known to exist are in the collections at Kew and 

 Glasnevin. 



Mormodes 



A genus of deciduous epiphytes, inhabiting Columbia 

 and Central America as far as Mexico. They are allied 

 to Catasetum, and require the same kind of culture, 

 excepting that they come from mountainous regions at 

 a considerable elevation. The Cattleya house is the 

 most suitable place for their cultivation. Like Cata- 

 setums, the whole of the pollinary apparatus, when the 

 beak of the columns is touched ever so lightly, is 

 released and tossed upwards with a jerk to some dis- 

 tance. The labellum, too, is a remarkable organ, being 

 so twisted as partially to arch over the column. The 

 whole genus has many striking floral peculiarities, some 

 of the species being very handsome, whilst others have 

 a delightful fragrance, which is acceptable even among 

 Orchids. The number of species known is about
