Nephrodium decurrens. Decurrent Kidney-fern. Cau- 
dex tufted; fronds lance-shaped, pinnate, drooping, a 
foot high ; pinnae sessile ; the rachis winged and chaffy ; 
sori situated at the end of the veins. This is a some-

house, but it will live in the open air if covered with 
leaves during the winter season. The light green droop-

Caudex creeping ; fronds very slender, hairy, pinnate ;
