SELECT FEENS. 



Owing to the great and rapid increase in the number of species and varieties in some 

 of the genera, anything like a full detailed description would tend to bewilder rather 

 than instruct the majority of readers of this work. Brief reference will be made to 

 many of the best species and varieties of ferns in their sections and selections for various 

 purposes offered, before the 

 subject is dismissed. 



AdlNIOPTERIS. A 



small genus of stove ferns, 

 which are both distinct and 

 attractive. A. radiata, 

 India, forms fan - shaped 

 fronds 3 to 6 inches high. 

 A. australis is a variety of 

 the preceding, differing 

 principally in being larger 

 and more vigorous. The 

 pots for Actiniopteris ought 

 to be half filled with crocks, 

 and the plants should be 

 potted in equal parts of 



crocks and charcoal broken up small, adding silver sand and a small portion of loam 

 and peat. Propagated by spores. 



ADIANTUM. 



A large and very popular genus, comprising species requiring gentle heat, others 

 that thrive in a cool greenhouse, and a few nearly or quite hardy. 



Bepresentative Species and Varieties. 



Davallia on Coek Block. 



A. jemulum.— Brazil. Fronds slender, tri-subquadri- 

 pinnate, 6 inches or more in length. Stove or 

 warm greenhouse. 



A. /ETHIOPICUM. — Spain. Fronds deltoid, quadri-pin- 



nate, 12 to 18 inches long, and 6 to 9 inches 

 broad. A. chilense and A. sulphureum are forms 

 of this species, A. assimile and emarginatum 

 synonymous. Greenhouse.
