Asplenium platyneuron (L.) Britton, Sterns & Poggenb.
Aspleniaceae (Spleenwort Family)
USDA Symbol: ASPL
Sterile and fertile fronds are entirely different in appearance and habit. Sterile fronds are only 2-6 in. long, have short, blunt, alternate pinnae, and are evergreen. Fertile fronds are 1-2 ft. long, erect-arching, and bear short, alternate pinnae below and longer, opposite pinnae above. Fronds occur in loose clusters, arising from the clumping rootstock. Colonizing roots are black and wiry.
The word, ebony, refers to the fact that the stalk turns a shining black with age.
