The v ariety andrciosii is v ery distinct, h av in g long n arrow
fronds, lanceolate-ovate in form, the p rim a ry divisions narrow,
and, as well as the secondary ones, more d istan t th an in the
normal form. In v o lu c re s immersed, and th e receptacles much
elongated. AA^e are in d eb ted to Mr. AVilliani A n d rew s, of D u b lin ,
for th e discovery o f this handsome v a rie ty ; he found it in the
ye a r 1843, at Iv e ra g h , Ire lan d .
Trichomanes radicans was found at Be llb an k , b y Bolton, in
th e year 1758, an d h e remarks th a t it was p len tifu l in this
station; it is now u n fo rtu n a te ly only a h ab ita t of days gone by.
In Jamaica, in woods, observed b y Swartz, Bancroft, and
Purdie . In Brazil, according to Raddi, Forb e s, Ma cra e, Scouler,
G a rd n e r, Sinclair, and Vau tio r, the va rie ty andrewsii appears
to occur, bearin g fronds from six to eighteen inches in le n g th ;
a similar form exists in th e F ore st of Esmeraldas, E l E q u a d o r,
according to Colonel H a ll. In the Azores, D r. H o ch s te tte r and
-Mr. H . C. Watson discovered it at an elevation of from two to
th re e thousand feet above th e level of the sea.
This E e rii, in a wild state, grows on damp shady rocks, and
delights to be within the spray of a waterfall. U n d e r p ro p e r
cultivation it can be made to be even more handsome th an when
growing in its own wild h a b ita t; on th e o th e r h an d , u n d e r
imperfect cultivation, it is an u n sig h tly F e rn . I t must be borne
in mind th a t th e fronds live th re e or fo u r years, and in th e
case of b a rre n fronds some have been known to keep gre en
and fresh as long as ten y e a rs; it is therefore desirable th a t
th ey should not be subject to in ju ry .
jMr. Jo s ep h H en d e rso n , of AWntworth, has b o th th e normal

th a t the AA^entworth specimens eclipse them. Mr. Flen d e rso n ’s
lilan is to grow it u n d e r a large hand-glass, the top only of
which lifts off, b y w hich means th e p la n t can be examined
without in ju ry to th e fronds in tak in g off and p u ttin g on th e
hand-glass. T h e fronds en tire ly fill th e space allotted to them,
like a dense m iniature forest. AA^ith my own plants I have
followed a similar p la n ; th e plants are p o tted in large saucers,
on pieces o f bro k en crock and freestone, with a slight p ortion
of vegetable mould and silver-sand, below w hich th e saucer
had been previously well drained, and upon this d rainage a
