  • Scientific Name

    Asplenium heterochroum Kunze

  • Description

    Species Description - Similar to Asplenium monanthes but distinguishable from all the lustrous- and dark-stiped Aspleniums (except A. resiliens and A. palmeri) by the lack of conspicuous hydathodes. The lower elevation (below 1400 m in Chiapas) (A. R. Smith, 1981), smaller, thinner pinnae, more delicate, arching fronds without deflexed pinnae, and smaller rhizome scales (2 mm) distinguish A. heterochroum from A. resiliens (q.v.). The occurrence at lower elevation and lack of terminal buds on the fronds distinguish A. heterochroum from A. palmeri (q.v.).
