OSMUNDA REGALIS. 201 
with a free admixture of silver sand. If grown in a pot, 
which must be large, or other confined space, it must 
have good drainage, and an abundant and continuous 
supply of water. With a moderate space for its roots it 
makes a noble-looking plant. For open-air culture it 
prefers a damp, shady situation, and in the compost as 
for pot-culture it will thrive and do well. It may be 
also grown in exposed situations with an abundant 
supply of water through the summer months. In such 
an exposure it will not produce nearly such fine fronds 
as in one more shaded; yet, if a constant supply of water 
and good drainage can be secured, it will do remarkably 
well. We have also grown this Osmunda very success- 
fully in a stove temperature, where it will, with plenty 
of light, form also a pleasing object. It is too large for 
a Wardian case. It may be increased by sowing its 
seeds, and also by division ; but by its seeds is the best 
mode.
