The Cooke Herbarium. — From the June number of Grevillea 
we learn that the large herbarium of fungi, transferred by M. C. Cooke 
to the Royal Herbarium at Kew, is now for the most part incorporated 
with that great collection. The specimens are distributed as follows : 
Hymenomycetes, about 11,000 
Gastromycetes and Myxogasters, 2,000 
Ustilagines and Uredines, 6,000 
Pyrenomycetes, 12.000 
Incomplet^e, 9,000 
The collection is a most valuable one, containing, as it does, con- 
tributions from many eminent mycologists, Berkeley, Curtis, Duby, 
Ellis, Fries, Levi lie, Montague, Peck, Ravenel, Rabenhorst, Winter, 
The Flora of Madagascar. — It may now be said with perfect 
truth that the vegetable productions of Madagascar have been, though 
not thoroughly, very extensively explored, and that the majority of 
the plants inhabiting the island are known to science. The country 
has been traversed by botanists in many different directions, its high-

forests penetrated, and large collections of plants have been made 
from time to time, which have been examined and described in various 
publications. Our knowledge of the flora of Madagascar is due, in

merson, Chapelier, Bernier, Lantz, Boivin, PerviUe, De Lastelle,
