and bearing exceedingly compact, firm and subrigid, caespitose, lanceolate, 
pinnated fronds, 2-6 inches long; pinnae oblong, paleaceo-hirsute, deeply 
pinnatifid or almost again pinnate; segments numerous, oblong or oval-ob¬ 
long, sinuated at the somewhat reflexed margin ; stipites castaneous, glossy, 
and as well as the rachises (especially when young), clothed with slender,

Woodsia Rajana. Newm. 
Hab. Elevated mountains in the north of England. First detected near the top 
of Snowdon by Br. Lhwyd, and by Br. Richardson in other parts of Wales. 
Westmoreland, Mr. Clowes , and Cumberland, Teesdale, Durham, Mr. Hail¬ 
stone. Breadalbane and Clova Mountains, Scotland. 
This species, in Europe at least, generally inhabits the same 
northern or high alpine regions along with W. hyperborea , and,, 
judging by the numerous specimens I have received, it is much 
more plentiful; by way of Siberia, Songaria, the Amur, and Man- 
chouria, extending to the northern islands of Japan, Hakodadi 
( Wilford ); indeed our finest specimens are from this latter 
country. In North America, although it attains a very high 
* Llva , from whence this name is derived, is the classical name for the island 
of Elba, so named, Sir Jas. Smith correctly observes, because Linnaeus believed 
this Fern to be the same as one figured by old Dalechamp, in an execrable figure, 
named “Lonchitis aspera Ilvensis,” with which indeed our plant has little affinity. 
Use has rendered the name familiar to us; and sanctioned as it further is by the 
authority of Linnaeus, so incorrect a name has never been attempted to be altered 
by any succeeding author.
