5. obtusa (M.). This form does not well associate with any of the 
others that we have seen. It is of medium size; the fronds narrow 
ovate in outline, with oblong obtuse shallow-lobed pinnules, set on 
nearly at a right angle, and having few coarse acuminate teeth. We 
have found this form well marked at Hampstead, Middlesex; others 
collected at Hastings, Sussex, resemble it. 
6. distans (M.). This is a marked variety, somewhat resembling 
Chanterie (7), but it is smoother, more lax in habit, and apparently 
growing to a larger size. The outline of the frond, which grows 
three feet high or more, is ovate. The pinne are distant, and 
scarcely enlarged on the posterior side in the upper parts of the frond, 
the lowest pair only being very oblique, and the next pair slightly 
so. The pinnules are set wide apart on the rachis, and are ovate- 
oblong, obtuse, the narrowed stalk-like base somewhat decurrent, 
except in the very lowest pinnules; the basal pinnules are deeply, 
the rest shallowly divided into short oblong obtuse lobes, which 
are coarsely toothed, the teeth acuminately-aristate. The sori are 
numerous, forming two lines near the midrib; the indusium is slightly 
glandular. It was found at Coombe Wood, Surrey, by Mr. S. F. 
Gray. 
7. Chanterie (M.). This is an elegant and a remarkably distinct 
form of the species, differing obviously in the narrowed form and 
attenuated apex of its fronds, its distant pinne, and its distinct 
blunt pinnules. The stipites, rachides, and under surface of the fronds 
are clothed with sessile or very shortly-stalked glands. The stipes 
bears numerous lanceolate and ovate-lanceolate entire scales, which 
are of various sizes, brown, with a dark central streak, and tipped 
by a longish, weak, bristle point. The fronds grow about a couple 
of feet in height, and are nearly erect in habit, and lanceolate or 
oblong-lanceolate in form, the base narrowing yet terminating 
abruptly, and the apex attenuated and caudate; those of the culti- 
vated plant, being more lax, are often ovate with an elongated 
point; they are always bipinnate, sometimes almost tripinnate. The 
pinnz are distant, somewhat spreading,'and more or less twisted, 
so that the upper surface is directed towards the zenith ; the lower- 
most pair, about three and a half inches long, and an inch and a half 
broad, are very unequally deltoid, their posterior basal pinnules being
