Mymenophyllum fucoides, C a v a n i l l e s . 0/ S w a r t z . )
Hymenophyllum—Memb ran e-leav ed . Fuciforme— .................. ?
I h e most magnificent Ilijmenophylluni known, growing in
shady woods, on trunks of trees in Chili and Ju a n Fernandez.
The fronds, which are broad, rigid, erect, smooth, and
shining, are tripinnatifid; segments broadly linear-obtuse, rounded,
and bifid, ultimate ones attenuated.
Rachis broadly winged. Stipes stout, rigid, and pale in
colour.
Length of frond from eighteen to th irty inches; and eight
inches or more broad. Colour bluish green or glaucous.
Involucres supra-axillary, marginal, minute, ovate, two-valved
to the base, and free; valves entire. Receptacles exserted.
Requires a very humid airy atmosphere, with a temperature
from 40° to 65°.
My thanks are due to Mr. Backhouse, of York, for the
frond illustrated.
