Tooting, have likewise succeeded in enriching our 
collections with a considerable number, received 
principally from Mr. John Henshall, their collector in 
Java and the neighbouring islands. Mr. Robert Sim, 
of Foot’s Cray, has an extensive collection, which 
he increases by importations, and is very successful

however, mention Messrs. Osborn & Sons, of Fulham, 
as having introduced one or two from Tasmania; 
Messrs. Jackson & Son, of Kingston, the Angiopteris 
Assamica, from Assam; and Mr. B. Williams several 
from various parts ; while all these and some others 
have also imported considerable numbers from the 
Continental gardens and nurseries.

ductions have taken place through several other 
Botanic Gardens in this country, as well as through 
some of the numerous amateur cultivators; but Fern 
amateurs have increased so largely during the last 
few years, that it is obviously impossible to mention 
them in detail. With respect to the former, the first 
provincial Botanic Garden in which Ferns were brought
