Leaf a palm long, very tender, rosy red, somewhat waved, blunt, the seg¬ 
ments bearing fruit. Fructifications roundish, small,, dark red. Huds. 
n. 27. Very tender. Blood red. Linn. Resembles F. laciniatus in 
texture, but in the blunt terminations of the teeth is more like 
F. pinnatfiidus in its younger state. If the figure of Wulfen in Jacq. 
Coll. iii. 16. 2, be the true Linnsean plant, our specimens are not so, but 
the figures in FI. Dan. are the same as ours. Wulfen’s figure represents 
the edges of the leaves very much crisped and curled.

Two or three inches in length and breadth; pale, red, thin, membranaceous, 
without rib or nerve. Branchings irregular, segments broadest towards 
the ends, waved, curled and fringed. Fructifications small, red, elevated, 
wart-like dots; at the base of the fringe ; each containing ten or twelve 
seeds. Lightf. This appears to be a smaller plant than F. laciniatus 
but unless the greater size of its fructifications will distinguish it, nothing 
hitherto mentioned is sufficient to do so.

F. laNCEola'tus. Stem strap-shaped: leaves membranaceous, with¬ 
out a mid-rib, strap-spear-shaped, simple, mostly on leaf-stalks, 
edged with processes of various lengths. 
Stackh. ii. \3—Gmel. 21. 3. 
Plant about four inches high. Stem near one and a half inch. Leaves flat, 
membranaceous, pinky red, strap or strap-spear-shaped, one and a half 
inch long, from the breadth of a straw to one quarter that size; fringed, or 
rather winged with appendages of very various lengths, the larger ones 
half an inch long and these sometimes toothed at the edge, but without 
any appearance of fructification. This has been considered by Mr. 
Hudson and others as a variety of his ciliatus, but it differs in having a 
stem, in showing no granulations on the fringe of the leaves, and also in 
their shape. It is nearer to F. holosetaceus , but has no appearance of 
bristles on its surface. 
Further observations are wanting to determine whether it be really a dis¬ 
tinct species. I suspect that the processes from the edge of the leaves 
may be other leaves in an incomplete state of growth.

well established species, it could not be retained. 
Specimens from Mr. Stackhouse, gathered on the coast of Cornwall. 
(F. reniformTs. Stem cylindrical, filiform, short, branched; ex¬ 
panded at its summit into a cartilaginous, flat, nerveless, simple, 
reniform or orbicular, entire leaf, when old proliferous from its 
margin; sessile, hemispherical tubercles scattered over the sur¬ 
face of the frond. Turner.
