It has often been remarked by lovers of British Botany, that 
the researches, and consequently the discoveries, were never so 
numerous as during the publication of Sir James Edward Smith’s 
‘Flora Britannica,’ and his and Sowerby’s ‘ English Botany;’ and 
we trust that what those works did towards promoting our know- 
ledge of the plants of Great Britain, the ‘Species Filicum,’ and 
the present work, will do by increasing our acquaintance with 
the Ferns of the whole world. We have, indeed, to a great ex- 
tent, already experienced this to be the case. These works have 
afforded the means of studying the genera and species, and have 
encouraged students and collectors abroad, and they are sure that 
their contributions of new and rare species will be turned to ac- 
count for the good of the public, and that they will be duly de- 
scribed and recorded. We are certain that our friend Mr. 'Thwaites 
will have pleasure in knowing that two of the rarest and most 
beautiful Ferns of Ceylon, which he has taken infinite pains in 
sending far into the mountain woods of Ceylon to procure and 
send to us in a living state, have at length reached us in safety 
and in the most beautiful condition; and that, in less than a 
fortnight after their arrival, they are drawn and engraved for the 
JUNE lst, 1861.
