176 NEW FERNS FROM WESTERN CHINA. 



secure some of these masquerading Ivy-flowers in various stages 

 of development, from the earliest to the latest, and so afford a 

 surer basis whereon to construct the morphological pedigree.

By J. G. Baker, F.E.S., F.L.S. 



The following are the novelties and more interesting species 

 contained in a large collection made in the Provinces of Hupeh and 

 Szchewan, in Western China, lately received from our indefatigable 

 correspondent, Dr. Henry, and a smaller collection sent by Mr. 0. 

 Ford, of the Hong-kong Garden. My last paper on new ferns from 

 the same region will be found in Journ. Bot. 1888, p. 225.
