LINDSAYA. 
Lindsaya (commonly called Lindscea) or 
Dryander, is a large genus of stove and greenhouse 
lerns, very few of which are grown in this country. 
Most of the species have one-sided leaflets of a 
somewhat transparent though leathery texture, 
approaching in shape a quarter of a circle. Lind- 
sayas are readily distinguished through the sori, 
marginal or nearly so, being placed at the summit 
of and uniting two or more veins, and through their 
being furnished with a double involucre opening 
outwardly. As now made up the genus contains 
Diellia, Eulindsaya, Isoloma, Schizoloma, and 
Synaphlehiiivi, For a long time the requirements 
of these Ferns were little understood. Of recent 
years, however, owing to their being differently 
created, some of the most interesting species have 
been established in this country. Although they 
require an abundance of water at the roots, perfect 
drainage for Lindsayas cannot be too strongly in- 
sisted upon, for they suffer considerably from the 
effects of stagnant water — as much, in fact, as from 
the want of atmospheric humidity. When properly 
established, these plants should be potted in a 
mixture of two parts turfy loam and one part fibrous 
peat, with just a dash of sand; and only a little of 
this mixture should be used in each pot, the greater 
part of which should be filled with drainage 
materials. They should then be either set on, or, 
better still, plunged in, a bed of sphagnum, kept 
close, and occasionally sprinkled overhead. Nearly 
all the species thrive fairly well under such treat- 
ment, although a few members of the genus, notably 
those native of New Zealand, such as L. linearis 
and L, trichomarioides, &c., naturally need a little 
less heat. With the few exceptions indicated, all the 
species require stove temperature. Lindsayas are 
usually propagated by the division of their crowns or 
of their rhizomes. 
L. linearis. 
This pretty, distinct, small, and rare greenhouse species, 
native of Tasmania, New Zealand, and West Australia, has
