Cryptogramma

(Greek, a concealed line, alluding to the sub-marginal sori). Polypodiaceae. A small genus of subalpine Ferns of both hemispheres. Lvs. of two sorts, the sporophylls contracted and the sori covered by the infolded margin of the segments, forming pod like bodies. Besides our native species, a second one, C. crispa, is found in Europe, and a third in the Himalayas. Name often incorrectly written Crypotogramme. Culture easy.
