blooms ver}' freely thi-ough the summer months, and is a very 

 desirable plant for a basket. 



Ada. 



This genus, as far as I am aware, contains but one 

 species, and is evidently nearly allied to Brassia. It is an

 Odontoglossum Alexandres, and treated in the same manner. 



A. aurantiaca. — But few plants of this most deskable 

 Orchid have been imported, until quite recently ; it is one 

 of the most distinct in colour, and lasts long in beauty. It 

 is a beautiful compact evergreen Orchid, growing from eight

 elevation of 8,500 feet. It is another addition to our now 

 numerous cool-house species ; blooms in autumn and early 

 spring. 



Aerides. 



The species of Aerides are among the most beautiful of 

 Orchids, many of them uniting every good quality that a plant 

 can possess, viz., rich, evergreen, and regularly- curved foliage ;

 straight or sHghtly bent, with leaves attached on opposite sides, 

 and they are nourished by large fleshy roots, shooting out 

 horizontally from the lower part of the stem. The flowers, 

 which are rich and waxy, proceed from the axils of the leaves,
