simpler upwards, the terminal segment with a rounded or obtuse outer margin, and the serratures of the 
sterile segments having a veinlet extending to the point (not to the sinus). The present species has both 
surfaces of the frond minutely pilose with appressed whitish hairs. The involucres are variable in shape, 
oblong and linear on the same pinnule, and rather few (3-7) in number. This is apparently a rare species, 
~ as I can not learn that it has been collected by any one in California since the time of Nuttall. It is No. 
11 of Ervendberg’s collection of Huasteca plants, and No. 687 of Schott’s collection made in Yucatan

IX. LOMARIA. Willd. 
Sori in a continuous band next the midrib of the contracted pinne of 
the fertile frond, covered till mature by an elongated involucre, either formed 
of the recurved and altered margin of the pinnz or else sub-marginal and 
parallel to the margin. Veins of the sterile frond oblique to the midrib, 
simple or forked and free. Fronds mostly elongated, pinnatifid or pinnate, 
in foreign species rarely undivided or bipinnate, of two kinds, the sterile 
foliaceous, the fertile commonly much contracted —A genus of about sixty 
species, finding its greatest development in the southern hemisphere. It is 
closely connected with Blechnwm, which has the involucre remote from the 
margin, and the fertile frond not much contracted. The two genera were 
united by Dr. Mettenius, but it is more convenient to keep them apart. 
Lomaria Spicant, Desvaux. 
Rootstock short and thick, very chaffy; fronds tufted, erect; sterile 
ones nearly sessile or short-stalked, sub-coriaceous, narrowly linear-lan- 
ceolate, 8-24 inches long, 1-3 inches wide, tapering to both ends, pinnatifid 
to the rachis into very numerous close-set oblong or oblong-linear often 
upwardly-curved obtuse or apiculate segments, the lower ones gradually 
diminished to minute auricles; fertile fronds sometimes three feet high, long- 
stalked, pinnate; the pinnze somewhat fewer and more distant, longer and 
much narrower than in the sterile frond, sessile by a suddenly widened 
base; involucres distinctly intramarginal.—‘“ Desv. in Berl. Mag. v, p. 325.”
