simpler upwards, the terminal segment with a rounded or obtnse outer margin, and the serratures of the 

 Bterile 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 

 in 1865.

 IX. LOMARIA. Willd. 



Sori in a continuous band next the midrib of the contracted pinnae of 

 the fertile frond, covered till mature by an elongated involucre, either formed 

 of the recurved and altered margin of the pinnae 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 Blechrmm, 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. 



Ijosnaria 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 pinnae somewhat fewer and more distant, longer and 

 much ^narrower than in the sterile frond, sessile by a suddenly widened 

 base; involucres distinctly intrainarginal. — "Desv. in Berl. Mag. v, p. 325."

From Mendocino County, California (Bolander) and near Crescent City (Brewer) to Oregon, British 

 Columbia, and Sitka. It therefore hardly comes within the geographical range adopted for this report, but 

 is still likely to be found to the south of the 40th parallel in the Coast Ranges of California. It is not an 

 uncommon Fern throughout Europe, and a form of it has been collected in Japan. The North American 

 plant was made a var. elongata by Sir W. J. Hooker in the Species Filicum, but the smaller European 

 form has been collected near Astoria, Oregon, by Prof, Wood, and the large specimens from the
