time engaged on the grasses. 
Alluding in the preface to the material utilised in preparing 
this volume, Sir Joseph states that the Ceylon collections in the 
Kew Herbarium are much richer than those in the Herbarium of

New Orchid Houses.—During the past year the Orchid Houses 
(Nos. XIII. and XIV.) have been entirely reconstructed. The old 
houses, which were erected in 1869, had proved ee Ede. to

Angrecum, Cypripedium and Anectochilus ; the cool (XIV. A)
