a living state. This reduction is consequent on Mr. Baker 

 having united, or what is termed " lumped," a number of 

 forms described by authors as species, under A. Filix-foemina, 

 which is widely diffused over the Northern hemisphere, pre- 

 senting many different aspects in the more or less divided 

 states of its fronds in different regions, some of which may 

 be admitted to be as distinct species as many other closely 

 allied Ferns. 



The species are widely distributed, being found in India, 

 Malay, and islands of the Pacific, A. Brownii extend- 

 ing to Southern Australia, A. umlrosum and A. axillare 

 being found in Madeira. In this country, especially in 

 Yorkshire, a number of what are called tasselled forms of 

 A. Filix-foemina are found, which have become great fa- 

 vourites with amateurs ; one trade catalogue alone contains 

 the fanciful names and prices of no less than 115.
