grower. When, however, in a place in which a perma- 
nently moist atmosphere may be depended upon, it grows 
freely in a mixture, in about equal proportions, of partly- 
decayed leaf-mould, fibrous peat, and silver sand. Also 
impatient of root-disturbance is the beautiful A. scolo- 
pendrifolium, which thrives best when pot-bound, providing 
the watering is carefully done. 
Fig. 11. ACROsSTICHUM AUBERTIL 
A, scandens, though usually regarded as a stove fern, 
grows very well in the intermediate house, where the 
winter temperature occasionally falls below 50deg. Fahr. 
It prefers a compost of an open nature made of fibrous 
loam, fibrous peat, partly-decayed leaf-mould, and silver 
sand, in equal parts, with abundance of water at the 
roots all the year round. To the species, &c., described on 
pp. 18-20, Vol. I., the following should be added. Except 
where otherwise indicated, stove treatment is required.
