14. obtusum (M.). This variety has broad lanceolate fronds, 
about two feet high, the leafy portion being about half as broad as 
long. The pinn® are broadish and tapering. The pinnules are 
flat, distinct, obliquely and very obtusely ovate-oblong, somewhat 
decurrent behind, cut into a few broad variously-toothed lobes, the 
teeth short and bluntish ; they have somewhat the appearance of 
blunt pinnuled forms of Lastrea dilatata. The sori form two lines 
nearer the midrib than the margin. It was found at Virginia 
Water, in Surrey, by Dr. Allehin. A nearly related plant has been 
sent from Todmorden by Mr. Stansfield. 
. 15. frondosum (M.) This is a larger and more compound state 
than the preceding, growing from two to three feet high, and having 
very broad lanceolate fronds, with broad approximate pinnee, and 
crowded pinnules. The fronds have thus a more crowded and leafy 
appearance than usual. The pinne are irregular in outline, gradually 
narrowing to a long taper point. The.larger pinnules are sometimes 
nearly or quite an inch long, and fully three-eighths of an inch in 
breadth; they are pyramidal, pinnatifid nearly to the midrib, the 
lobes blunt oblong toothed, the lowest anterior ones frequently bear- 
ing half-a-dozen sori, sometimes more, and most of the lower lobes 
several. In these sori the tendency to become arcuate is strongly 
marked, the-one placed nearest the midvein of the pinnule, on 
each lobe, being uniformly horse-shoe-shaped. The stipites and 
rachides are quite red in plants we have met with at Mayford, in 
Surrey. The same variety has been sent from—Denbighshire : 
Ruthin, 7. Pritchard ; and Somersetshire: N ettlecombe, C. Elworthy. 
16. latipes (M.). A very remarkable variety, with pyramidal or 
elongate-triangular fronds, which are rather above two feet in height, 
and about nine inches across the base where it is broadest. The 
stipes is about ten inches or a foot long; and the pinns are broad, 
two inches or upwards in width, and somewhat irregular. The 
pinnules are large and coarse-looking, the full-sized ones averaging 
two inches in length or upwards, the lowest sessile, the rest more or 
less adnate and decurrent, distinct, pointing forwards, ovate-lanceo-
