CULTIVATION.

under the above name. This hygrometric property 
seems to indicate that this and its allied species are 
subjected to occasional drought in their native localities. 
But although they may frequently undergo this pro- 
cess in nature with impunity, it is, however, not 
desirous to be too often repeated on plants artificially 
cultivated. Shallow pots, four to five inches in 
diameter, best suit this section ; and being firm 
holders, it is necessary to insert pieces of soft sand- 
stone or potsherds amongst the shallow soil, so as 
to fix the plant firmly in the pot. The extremely 
delicate nature of the tissue of these little plants neces- 
sitates that a position the shadiest and moistest in a 
Fernery should be assigned to them. S. Willdenovii, 
S. filicina, and others are termed deciduous from their 
fronds decaying altogether in the early spring ; new 
fronds, however, soon begin to grow. 
The species of true Lycopodium are also numerous, 
some being terrestrial and others epiphytal, hanging 
from the trees like various-sized cord, one to four feet in 
length. Of the terrestrial, five are natives of this country; 
they, as well as several beautiful species that have from 
time to time been introduced from North America, 
refuse to become domesticated under ordinary treat- 
ment ; to which must be added the wide-spread and 
beautiful tropical species L. cernuum. Equal ill success 
attends the epiphytal species ; for although frequently 
imported, they are yet but poorly represented in our 
collections ; they adhere to trees by producing many 
fibrous roots, which ultimately become a large spongy 
mass. 
The extra height of roof required for the growing of 
good examples of Tree Ferns excludes them from many
