 Swartz 46. Vancouver Island, and 49 J X. Lat 

 Dr. Lyall. 



Cystea, Smith. 



I adopt Sir J. E. Smith's characteristic name 



for this genus, as I do not consider Bernhardt 

 genera to be of much value.— Eng. Fl. iv. 260, 264. 



1. C. bulbifera (Linn. 1553). 



Aspidium b., Swartz 59. "A. atoma-rium

 Ferns, t. 9; H . alpina, Moore, Xat.pr. Br. Ferns t. 

 106. More properly II'. Ilrtusis var. alpina. 

 Scarcely distinct from No. 1— from which, 

 it may usually be distinguished by its smoothness.' 

 shorter pinnae, more rounded lobes, and darker 

 (often almost ebeneous) sti t es which have fewer 

 scales. 



3. TV. hyperborea (Liljeb.) 



Newfoundland, per Geological Survey. I re- 

 gard the Acrostichum hi/perlioreum of L 

 quite distinct from the A. alpinurn of Boltou, (.Fil. 

 Brit. t. 42), and as very closely allied to No. 4. 



4. TV. glabella, E. Brown. 



Rich. App. 39; Hook. Fl. Bor.-Am. t. 237. Pro- 

 bably identical with Xo. 3 and thus If. hyperborea

Sub. HYMENOPHYLLE.E. 



Hymenophyllum, Smith.
