CRYPTOGAMIA— FILIGES. Aspidiuni. 295 



north-east corner of Rivelston wood, near Edinburgh 3 also 

 among bushes under the high rocks at the top of Cromford 

 moor, near Matlock bath, Derbyshire. 



Perennial. July. 



About one-third the size of the last, with which it agrees in general 

 habit and structure, but the le(i/Iets are rather more ovate, and 

 their segments more closely crowded together, less serrated at 

 the sides, but their bristly teeth more numerous at the extremity 

 of each segment. J\Tasses few, small and rather scattered. 

 Cover thin, pale, flat, not tumid nor kidney-shaped, but more 

 orbicular, with a deep notch at the lower part, and finally turned 

 loosely aside, by the few, rather large, shining, brown cap- 

 sides, whose rings are very apjjarent. Sometimes the masses 

 are placed at the very edges or points of the segments, and the 

 covers are often torn ; but they are never tumid, like a kidney, 

 nor fixed closely by their outer margin, as those of J. dUatatuin 

 are. I think these two species may always be distinguished by 

 the situation of their fructification, and the nature of their 

 covers. 



Mr. Henry Shepherd, of the Botanic Garden, Liverpool, raised 

 the A. dumetorum in plenty, from seed brushed from a Derby- 

 shire specimen. The individuals, whether cultivated in pots or 

 on rock-work, retain their original habit and characters, the 

 largest not exceeding a foot in height. Others, from Scotland, 

 have rather more distant lenjlcts^ with more spreading segments, 

 but i\\(d\\' fructijications agree, both difl'ering alike from A. dila- 

 talum. The midribs of their leci/lets accord with ihis last, and 

 not at all with A. spinulosuni.

Frond doubly pinnate; leaflets linear-oblon<ij, pinnatifid, 

 serrated, pointless. Stalk smooth. Cover oblong-, finally 

 somewhat kidney-sha})ed, jj^gg^d.
