Tins Fern appears to be very little kn ow n to botanists, and wo arc much indebted to the Rev.
R. T. Lowe for sending us fine specimens gntbercd in Madeira, at Ribeiro d'Amestade, at tin
elevation o f 3 0 0 0 fe e t above the lev e l o f the sea, aud from which our figure and description have
been made. T lie sc , to o , wc liavo l,ad on opporttmlty o f comparing with an authentic specimen o f
Mr. Masson's, and thus determining it to be the P olypodium e longatum o f th e Hortus Kewensis. It
is assuredly allied to N ephrodium F i b M a e ; hut its peduncles are more slender, more eomponnd,
more elongated, the underside is miimte ly dotted with crystalline glands, and the involucre, which
is very convex, is also studded witli glands, som e cryst,allinc, others opake.
