CATALOGUE. 331 



Yar. commune. 



Frond ample, delicate, 2-4 feet high, broadly oblong-ovate, twice pin- 

 nate ; pinnae elongated (4-6-8 inches long) ; pinnules oblong-lanceolate, 

 pointed, more or less pinnately incised and serrate, distinct or confluent on 

 the secondary rachis by a very narrow and inconspicuous margin ; sori 

 short ; indusium straight or variously curved. — Aspl Filix-fcemina of most 

 authors. 



Eastern America, common in moist, shaded woods. Mount Graham, Arizona, Bothrock. Cali- 

 fornia, Brewer, Bolander, Kellogg, etc. Ruby Valley, Nevada, Watson. Southern Utah, Palmer. 



The ordinary, fully developed form of the specie?, which I am unable to separate from the com- 

 mon European plant. Moore's plate of A1h. Filix-fomina, var. ovatum (t. 32), well represents an ordinary 

 average specimen. In living plants, the stalk and rachis is often of a beautiful brownish pink, but this 

 color is lost when the frond is dried for preservation. 



Var. cyclosorum, Euprecht. 



Fronds very large, often 5 feet high and 18-20 inches broad; the pin- 

 nules often an inch long, oblong-lanceolate, pinnatifidly incised, or nearly 

 again pinnated; sori roundish; indusium very short. — Distrib. Crypt. Vase.

 Ferns, t. 30 ; var. cyclosorum, Moore, Index Fil. p. 183. 



Oregon City (Harford). Port Orford, Oregon, Gen. Kautz. Vermont, C. C. Frost. 



The largest form of the species, occurring on the west coast from Oregon to Alaska, rarer in the 

 Atlantic States, and given by Moore as growing in Great Britain, France and Lapland. Var. Sitchense 

 of Euprecht, 1. c, is probably the same thing. The crested, multifid, and irregularly developed forms 

 of the Lady Pern are comparatively rare in America, but it is not to be doubted that diligent search 

 would bring them to the light. One of them, var. laciniatum, Moore, is mentioned by Mr. Davenport as 

 occuring in New Jersey. (See Bulletin of Torrey Club, vol. vi,p. 168.) Of the varieties above described, 

 var. latifolium is the most distinct, but all are closely connected by various intermediate conditions. 



Tribe iv. ASPIBIEJ3. 



Xn. PHEGOPTEEIS. F<§e. 



Phegopteris alpestris, Mettenius. 



Rootstock short and thick, erect or oblique ; stalks 4-10 inches long, 

 bearing a few large brown spreading scales near the base ; fronds oblong- 

 lanceolate, 1-2 feet long, pinnate with delicately bipinnatifid deltoid-lanceo- 

 late pinnae, the lower pinnae distant and decreasing moderately ; pinnules 

 ovate-oblong or oblong-lanceolate, incised and toothed; sori small, rounded, 

 sub-marginal. — Fil. Hort. Lips. p. 83 ; iiber Phegopteris, p. 1 0. Aspidium 

 alpestre, Swartz. Polypodium alpestre, Hoppe. Hooker, British Ferns, t. 6.
