    near the ascent of Glyder Vawr, from the Llanberris side, and I am uncertain to which of the supposed species it belongs. I believe Mr. Roberts, of Bangor, first discovered the plant in this locality, but I fear it is extinct, as this gentleman failed in his search after it, in company with Mr. C. C. Babington, in 1835, and I spent hours hunting diligently in the same place, in August, 1838. Roots long, fibrous, brown. Rhizoma tufted, brown, slightly scaly: the young fronds appear in May, and last till September or October; the shape of the frond is linear, lanceolate, and pin- nate; the pinne are attached by their stem only: they are indented but not pinnatifid. Sadler, who appears to consider the ; plants distinct, thus characterises them :— De filicibus veris, &c. p. 45. W. hyperborea. “‘ Frond linear, lanceo- late, pinnate, beneath pubescent: pinne nearly ovate, obtuse at the base, unequally cuneate, nearly sessile, obtusely lobato-pin- > natifid; masses of thecee becoming nearly Jim, confluent; stipes smooth, rachis pilose.”— Nadler, l.-c. W. Ilwensis. ‘‘ Frond oblong, pinnate, be- neath hairy; pinnz opposite, lanceolate, pinnatifid; the lobes oblong, obtuse, the lower ones spreading: masses of thecz con- fluent; stipes and rachis scaly-villose.”— Sadler, 1. c. A small portion of the rachis is naked, the veins are irregularly distributed, frequently the midvein is not to be traced without dif_li- culty, no single vein appearing to have a superiority over the rest: none of the veins A reach the margin, and each at its extremity bears a mass of thece. The plants are represented of the natural size; the two pinne detached are magnified, i | the upper shows the masses of thecee in their a “AS en natural situation, the lower exhibits the i 7 ge ie mena, and -thionpio tino Mace nee Goal yy of a ‘ velns, an ete points ef attachment of the aan ple thece at their extremities, the thecee them- we aye selves being removed.
