Asplenium Kamchatkanum sp. now Rootstock not seen. 

 Stipes nearly naked except for a few light colored scales at base, 

 dull straw colored, : ft. long, stout angled. Rachis slender, 

 slightly furfuraceous at nodes; lamina 12 to 20 in.. long, ovate, 

 8 in. broad, bipinnatifid, slightly diminished in width at base, re- 

 duced suddenly at tip, which is pinnatifid and acute; mid-pinnules 

 lanceolate, 5 to 7 in. long, 1 in. wide, ascending, lower ones 5 in. 

 long and opposite, upper ones alternate, about 1 in. apart except 

 the lower, which are 3 in. distant, all acuminate semi-pedunculate, 

 pinnatifid to within a line of costa, sinus acute V-shaped, costa 

 slightly furfuraceous; pinnules 5 to 8 lines long, 2 lines wide, ex- 

 panded at base 011 both sides and adnate, never cut quite to costa, 

 regularly 6 to 8 lobed, lobes entire and pointing forward, end of 

 pinnules round, blunt, entire or faintly serrate; veins branched 

 once or twice in each lobe; sori medial, one in each lobe forming 

 one long row on each side of the midrib, extending not quite to 

 the tips of the pinnules, but nearly always one in each swelling 

 of the segments at base. Indusium tumid, straight, the free 

 edge slightly ragged, persistent ', dark brown. 



The type specimen belongs in the United States National 

 Herbarium, but there are two pairs of pinnae of the same in the 

 Eaton herbarium at Yale. The labels read: "Herbarium of the 

 U. S. North Pacific Exploring Expedition, under Commanders 

 Ringgold and Rodgers, 1853-56. Asplenium filix-foemina. 

 Bernh. C. Wright Coll. Okotsk Sea, J. Small." The fern is a 

 pure Asplenium. The sorus is straight, and when mature the 

 indusium is forced back but not covered by the sporangia, and 

 being on one side it looks like the half indusium of a Hemitelia. 

 Its affiliation seems to be with the West Indian Asplenium con. 

 chatum, but the sinuses are not so broad and are much sharper 

 the pinnules are more expanded at base, the sori are larger and 

 not so close to the midrib, and the veinlets instead of being simple 

 are once forked.

— Mr. Gilbert's statement in a recent number of this magazine 

 that the young plants of Botrychium obliquum produce fruit the 

 first year, still leaves unexplained the behavior of the sterile 

 plants that are always found with the fruiting specimens, fre- 

 quently outnumbering them. Is this another proof that the 

 Botrychiums rest from spore-bearing in alternate years?
