represent the tree ferns of the West Indies. All the foregoing be- 
long to the tree-fern family proper, the Cyatheaceae. It is 
hoped to materially increase the representation of West Indian 
species by an expedition to Porto Rico during the present summer. 
Arboreous species of small dimensions occur occasionally in 
other families of the ferns than the tree-fern family ; our native 
Royal fern and Clayton’s fern which grow plentifully in marshy 
daceae, is represented in the tree-fern house by a live specimen 
of Yodea barbara, native of Africa and Australia, obtained by 
exchange with the Fairmount Park conservatories. 
few of the true fern family, Polypodiaceae, also form small 
erect trunks; these are represented in the collection by several 
fine specimens of Blechnum Cordovense from Brazil, presented by 
Mrs. F. L. Ames; some of the spleenworts (genus Asp/enium) 
likewise form low erect trunks and we possess two individuals of 
a species from Costa Rica. 
It is desired to increase the tree-fern collection as rapidly as 
possible, and we will be glad to receive any plants which can be 
spared from other collections.
