ehes high. Frond solitary, from a torn membranaceous sheath, 

 divided into 3 or 4 unequal segments or pinnatifid ; the seg- 

 ments often much cut. Spike subcompound, unilateral and in- 

 terrupted. See Hitchcock in Sill. Jour. vi. 103. 



2. B. fumarioides Willd. : scape naked ; frond smooth, radical, 3- 

 parted, bipinnate ; pinnules lunate, crenate ; spikes bipinnate, and B. ob- 

 liquum Muhl. B. fumarioides var. obliquum Torr. Botrypus lunarioides 

 Mich. 



HAB. Shady woods. N. Y. to Car. June. If. Fern 912 

 inches high. Frond petioled, mostly ternate, but often more 

 compound ; segments lunate, closely resembling those of B. lu- 

 naria. Capsules in double rows on the branchlets. I have care- 

 ,. fully examined an authentic specimen of B. obliquum in the her- 

 barium of Mr. Schweinitz, but can observe nothing to distin- 

 guish it from this species. 



3. B. dissectum Willd. : scape with the frond near the base ; frond 

 ternate, thrice pinnatifid ; segments decurrent, linear, wedge-shaped, 

 sharply toothed at the end. 



HAB. Dry woods. Near Philadelphia. Conrad. Washington 

 City. Collins. N. Y. to Flor. Pursh. June. 2[. Easily 

 distinguishable from the next by its smaller size, and by the 

 much more finely divided segments of the frond. 



4. B. virginicum Sicartz: scape bearing the frond in the middle ; 

 frond 3-parted, bipinnatifid ; segments obtuse, about 3-toothed ; spikes 

 bipinnate, divaricate and B. gi-acile Pursh. Botrypus virginicus Mich. 



HAB. Shady woods. Can. to Car. June, July. If. Fern 

 often 18 20 inches high. Frond near the middle of the stipe, 

 divided into 3 principal branches, which are again variously 

 divided. Spilie pinnate or bipinnate, smooth or a little hairy.
