Trichomanes—continued. 
symmetrically and also more vigorously, but this hardly 
compensated for the length of time which seedlings take 
to develop, for the plants which in 1886 were only in 
24in. pans were produced from spores sown on turfy peat 
in 1882. The experiment, however, was interesting from 
the fact that the young subjects thus obtained under 
artificial conditions were the first of which there is any 
record, and they conclusively proved that, with a certain 
amount of patience, Trichomanes may, like most other 
Ferns, be propagated from spores, especially when these 
can be gathered and sown immediately.

T. meifolium (Spignel-leaved).* fronds tufted, 2ft. high,

which, standing forward as in Todea superba, give the whole

7000ft.), 1871. One of the most beautiful of all Filmy Ferns.

T. r. Andrewsii.* This beautiful variety mainly differs from 
the type in having narrower fronds, with more distant and 
distinct leaflets. See Fig. 729. 
T. r. proliferum (proliferous). fronds, when fully developed, 
dotted over with small bulbils, from which young plants are

TRICHOPILIA. To the species described on 
pp. 83-4, Vol. IV., the following should be added’: 
T. brevis (short).*  /. two or three to a scape; sepals and 
petals greenish-yellow, blotched with chocolate, linear-lanceo- 
late, acute; lip white, slightly flushed and veined with yellow 
on the front lobe and disk. J. solitary, elliptic-lanceolate, 6in.

about 1891. (G, C. 1895, xvili., p. 641; L. vii., t. 332.) 
T. coccinea marginata (scarlet, margined). The correct 
name of 7. marginata, T. coccinea (B. M. 4857) being now 
regarded as a species. Other forms are crispa and lepida 
(both described as species in Vol. IV.), and olivacea (sepals 
and petals elivaedoul): 
T. crispa is a form of 7’. coccinea.

(R. G. 1888, t. 1276, f. 2.) 
T. lepida is a form of 7. coccinea. 
T. punctata (dotted).* This is allied to 7. lawa, but differs 
from that and all other species in having the sepals and petals 
coyered with numerous reddish-purple spots on a light green 
ground ; lip greenish-white. Costa Rica, 1890. 
T. Wageneri and 1, Warscewiczii are grown in botanical collec-

star-shaped flowers on slender stalks (B. M. 7350). It is

TRICHOSMA. To the species described on p. 86, 
Vol. IV., the following variety should be added: 
T. suavis Meulenaereana (Meulenaer's). his differs from

brown. Sikkim, 1894.
