CRYPTOGAMIA. FILICES. Poly sodium. 1001 
Seven or eight inches high. Stem red, smooth, slender, convex on one 
side, bare for two or three inches from the base. Wings distant, spear-* 
shaped, acute; leafits strap-spear-shaped, the edges toothed. Mr. 
Bolton has very well observed, that the wings are distinct all the way 
up, not becoming confluent at the top, and that the leafits on the upper 
side the secondary mid-rib are larger than those on the lower, by which 
it may be distinguished from P. fragile. The regular serratures on the 
sides of the lobes also afford a good distinction, the lobes in P.fragile 
being only serrated towards the end, and that very irregularly.

Fructifications near the rib of the secondary wings. Bolt. Plant from five 
to eight inches high. The three leaves placed near the end of the stem, 
one terminal and one on each side. The Rev. Mr. Baker observes, that, 
“ at the point where the lower pair of pinnae branch from the stem the 
plant forms an obtuse angle and leans backward. This appears to be 
occasioned by four strong glands on the upper side of the stem and two 
on the lower. These glands attend the angles formed by the other wings, 
but decrease as they advance.”

(Mr. Brunton has found a large variety of this plant near the first water¬

(P. CALCA f REUM. Frond three-branched: branches douhly pinnate, 
erect, rather rigid: segments obtuse, somewhat crenate: masses

* (Derives its specific name, Spvonlepli, from being occasionally found among the mossy 
roots of oak trees. It has been supposed to possess medical qualities somewhat similar to 
those of its congeners. E.)
