pear to me quite as]>i(liaceous. In all my perfect specimens, the base of the 

 stipes is thickly clothed with very long, glossy, hlack, lanccolato-suljulate scales, 

 having hrown margins. The involucres arc quite plane.

Hah. Temperate and colder parts of Europe and the United States, Canada 

 and the Hudson's Bay territories, east of the Rocky Mountains. — I have always 

 considered this a well-marked species, although a plant called Lastr. nliginosa 

 has heen united with it, which 1 helieve rather to he a state of N. spinulosum. 



104. N. (Lastrea) Goldieanum, Hook. ; caudex stout sub- 

 erect, stipites tufted a span to a foot long bright stramineous 

 very paleaceous at the base with large ovate acuminate glossy 

 scales some dark-brown others pale ferrugineous, fronds 

 large l5-2i feet long ovato-oblong acuminate submembra- 

 naceous pinnate, at the base subbipinnate, pinnce'5-6-S inches 

 long H-2 inches wide petiolate deeply pinnatifid all except 

 the superior ones nearly to the base, segments rather distant 

 oblong subfalcate acute sharply and coarsely serrated the 

 base decurrent, the lowest pinnule may be said to be pin- 

 nated but the decurrent bases form wings which extend more 

 or less to the petioles, veinlets once or twice forked, sori on 

 the superior branch distant forming two series much nearer 

 the costule than the margin, involucres rather small mem- 

 branaceous reddish -brown cordato-reniform plano-convex. —
