ASPLENIUM vieide, Huds. 
Green Spleenwort. 
Asplenium viride; caudex short, creeping, clothed with black subulate scales, 
forming a closely compacted rooting mass; stipites densely csespitose, two 
to four inches long, slender, glossy-black below, then castaneous or stra¬ 
mineous, green in the rachis ; fronds three to five, rarely six inches long, 
linear-lanceolate, submembranaceous, bright-green, glabrous, scarcely acu¬ 
minated, pinnated ; pinnae two to three lines long, rather distant, all petio- 
late, rhombeo-ovate, obtuse, more or less obliquely cuneate at the base, 
deeply but rather irregularly crenate, scarcely lobed; veins subflabellate ; 
sori two to four near the disk, remote from the margin, oblong, oblique, at 
length confluent; involucres very thin-membranaceous, soon obliterated.

Hah. Eocks in mountain districts of England, Wales, and Ireland ; especially 
abundant in Scotland.—Upon the continent of Europe this species appears 
more universally distributed than in Britain; from the extreme north, Nor¬ 
way to Italy, Spain and Dalmatia in the south. In Northern India it is 
found in the western districts of Himalaya (12,000 feet elevation, Strachey 
and Winterbottom) ; in Bussia and Siberia. In North America it appears 
in the Eocky Mountains ( Drummond , Bourgeau). 
This is one of the most delicate and elegant of our Terns, and 
was supposed by myself and others to have been confounded by 
Linnaeus with Asplenium. Trichomanes , from the fact of his calling 
it “ A. Trichomanes ramosum but he seems merely to have 
adopted Bauhin's brief character for his specific name, for which, 
as observed by Sir James Smith, Hudson's “ A. viride '' is now 
universally substituted. Linnaeus's plant had the frond in an 
abnormal branched state, as represented by Bolton. The dis-
