whole of the leafit seems covered by them, whilst in P. Filir-mas the upper end is always bare. The lower pair of leafits on each wing, that is, the pair next to the principal or primary leaf-stalk, stand close to it, and parallel with it, pointing upward and downward. The breadth of the leafits varies considerably in different plants, but when they are narrow and the wings distant, the whole has a remarkably light and

elegant appearance. FEMALE POLYPODY. (Welsh: March-redynen fenyw. Aspidium Filis

P. June-Sept. (Aspidium irriguum, E. Bot. 2199, scarcely one-fourth so large as the pre

ceding, of which, nevertheless, some good Botanists have thought it a variety; and, indeed, after long cultivation, though raised originally from seed, it considerably approaches that species. In a wild state the fronds are of a more narrow lanceolate figure, and of a paler pellucid green; the main stalk occasionally scaly, but in general quite smooth, and exactly quadrangular, though the latter circumstance varies. Leafits shorter, and somewhat less linear than in F. fæmina, deeply serrated, or

partly pinnatifid, their segments sharply cut, without bristly points. About the margins of clear springs. Several places near Tunbridge. Mr.

T. F. Forster. Eng. Fl. Abundant at Tintern. Mr. W. Christy. E.) (P. DILATA'TUM. Frond doubly winged : leaflets deeply wing-cleft:

4. 28. E.) From four to seven inches high. Stem red, bare for about two inches at

the base; smooth, slender, brittle. Leafits more than twice as long as they are broad. In habit appproaching nearly to P. rhæticum, but it is not distinctly doubly winged like that plant, nor are the lobes of the

leafits regularly serrated at the edges, as in that. Var. 2, Primary wings spear-shaped, acute; leafits crowded.

Bolt. 97Barr. 432–J. B. iii. 741. 2-Seguier. 1. 1. From two to six inches high. Stem red, bare for half to one and a half

inch from the base ; smooth, brittle, but less slender than in the precede

ing. Leafits not equal in length to twice the breadth. Var. 3. Primary wings spear-shaped, blunt. About three or four inches high. Stem red, bare for half to one inch from

the base ; smooth, brittle, slender. This has a general resemblance to P. dentatum, but differs from that in

the colour of the stem, in being doubly winged, and in the want of fine

teeth at the ends of the lobes. Mr. Griffith, of Garn, Denbighshire, favoured me with specimens of these

three varieties gathered from the same root, and I have seen a single

specimen uniting the characters of the two former. BRITTLE POLYPODY. (Aspidium fragile. Sw. Willd. Hook. Cyathea a fragilis. Roth. Cystea fragilis. Sm. Dry stony places, and old buildings, in the mountainous parts of Britain.

E. Bot. 163. Three or four inches high. Stem brown green, slender, bare for one inch or

more at the base; edged with a narrow border on each side. Wings nearly

triangular; leafíts three-cleft, the middle segments sometimes notched. I am indebted to J. Wynne Griffith, Esq. for a beautiful specimen of this

plant. It is sufficiently distinct from P. fragile, though in habit much resembling our third variety of that species. Both this and P. fragile have their capsules in a globular cyst, which seems attached to the foliage at one point only, and readily separates from it.

Seven or eight inches high. Stem red, smooth, slender, convex on one

side, bare for two or three inches from the base. Wings distant, speare 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. (RED-STEMMED POLYPODY. P. rhæticum. Dicks. Bolt. Aspidium rhe

Mr. Baker observes, that, " at the point where the lower pair of pinnæ 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." (THREE-BRANCHED POLYPODY. E.) Dry stony places in Yorkshire, Lan

* (So called from a, privative, and Stairw, to moisten or become wet; because its leares are said to resist moisture ; but how far this name may have been originally applied to our plant seenis questionable. Hippocrates describes the Fern of the ancients as xanlipud dov, beautiful-leared ; Theocritus xãoepór å sikytov, the green Adiantum. E.)

+ (This very elegant plant is chiefly used for making syrup of capillaire ; for which purpose also the wore common Asplenium trichomanes is occasionally substituted ; an immaterial imposition, as neither plant seems to possess either pectoral, or any other active virtues. This Fern may be increased by planting in pots of lime rubbish, but sometimes requires sbelter in the winter. E.)

(Froa Opis, tfixos, hair. Respecting the latter part of the name etymologists are not agreed. The term, so far as intelligible, would seem to refer to the slender shining stalks common to most Ferns, which occasioned such plants to be called capillary herbs; and also to the reputation of improving the growth of human hair, an inference equally futile with many others deduced from analogous appearances. E.)
