Nepheodium (Lastrea) Oreopteris; caudex short, erect or decumbent, copiously 
scaly ; stipites short, tufted, scaly below; fronds l|-2 feet long, firm-menu 
branaceous, broad-lanceolate, gradually tapering and attenuated below, glan¬ 
dular ; pinnae two to three inches long, patent, sessile, from a broad base 
lanceolato-acuminate, deeply (more than halfway down) pinnatifid, from 
near the middle of the frond gradually becoming shorter downward, more 
distant and deltoid, the lowest less than an inch long; segments plane, 
nearly entire, oblong, very obtuse; veins simple or forked; sori quite mar¬ 
ginal ; involucres very delicate, membranaceous, more or less toothed at the 
margin, soon obsolete ; rachis often subulato-squamose ; costae pubescent.

Hab. Frequent in exposed situations in hilly and mountain regions, in England, 
Scotland, and Ireland; yielding a balsamic fragrance when handled, from 
the copious glands of the frond. 
This well-marked species is common on the continent of Eu¬ 
rope as far north as Norway. It appears in the middle of 
Russia, Lithuania, Volhynia, Moscow; and we have specimens 
from as far south as Asturias in Spain, Burieu, in Herb. Nostr. 
As this is marked from “ Pico de Arras and Pico de Tozaque , 55 
it is, I have no doubt, the locality alluded to by Mr. Moore, when 
he says, “ We have a memorandum of its occurrence at Pico, 
—one of the Azorean islands being probably intended / 5 The 
North American specimen in the Hookerian herbarium, also 
mentioned by Mr. Moore, is there marked from “Herb. Turner , 55 
and bears no stamp of authority whatever, and, being incor¬ 
rectly named Aspid. marginale , was on that account probably 
believed to have been American.
