A. Pinnatifid or pinnate; basal pinnae, triangular, wide spaced; 



basal segments, or pinnules, longest and paired; pinnae, 

 scaly beneath, outlines regularly tapering, or nearly so; 

 segments bluntly triangular, pinnules, oblong, both dentate; 

 scales at base of stipe, delicate, pale, comparatively few, 

 rarely with dark centers, (cristata, floridana, boottii.) 



* Almost wholly pinnatifid, slightly scaly beneath, segments 



oblique, bluntly triangular. Cristata 



a. Linear lanceolate, few sessile fertile pinnules 



Cristata 



b. Broad lanceolate, always pinnatifid, basal segments 



large Clint oniana 



* Largely pinnate. 



c. Long obovate, pinnules sessile largely bluntly triangular 



to oblong, very scaly beneath Floridana 



d. Lanceolate, pinnules largely oblong, often bidentate, 



sessile to slightly stalked, slightly scaly beneath. Boottii 



B. Almost wholly deeply pinnatifid ; basal pinnae, ovate, close 



spaced; basal pinnules, above, longest, opposite: below, 

 shortest, alternate, reduced or absent; pinnae, slightly 

 scaly beneath, outlines very irregularly tapering ; segments 

 and pinnules, long, subfalcate, obscurely dentate; scales 

 at base of stipe, abundant, dense, alutaceous with very dark 

 central stripe, (Goedieana.) 



e. Broad ovate, pinnae lapping ; segments, close ; apical pinnae 



crowded; scales alutaceous Goldieana 



f. Lanceolate, pinnae and segments not close or lapping, 



apical pinnae not crowded ; scales richly alutaceous

Though the ground is frozen and it is snowing between bursts 

 of sunshine, the influence of spring is making itself felt about the 

 roots of Schizcea pusilla which is now putting up its young 

 croziers. You have to lie flat on the ground and use a pocket lens 

 to see them, for as they make their first bow to the world they are 

 hardly as big as a pin's head. Last year's sterile fronds are as 

 green as ever where they have had the advantage of some cover- 

 ing of snow and the situation is somewhat sheltered. Where the 

 plants have been directly exposed to the elements, the fronds are 

 yellowish or brown.— C. F Saunders, Schizceland, Feb. n.
