 fine species, while through other sources they have 

 obtained many additions from Australia, New Zea-

 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 

 in raising plants from spores ; and the Messrs. Back- 

 house & Son, of York, the principal nurserymen

 have likewise been introduced by other nurserymen, 

 but the above are the principal of those who have 

 obtained them from their native countries. I may, 

 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. 



In addition to all these sources, occasional intro- 

 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
