Discussion
Plants of Distichium capillaceum form dense, rather silky tufts and the slender, spreading, distichous leaves with shiny, whitish, oblong, sheathing bases are characteristic. This is a taller species than D. inclinatum, with plants less crowded, capsules erect-symmetrical and cylindric, and spores smaller. In more northerly or alpine regions with more severe climatic conditions, the plants are often shorter, more compact, and have shorter leaves.
Selected References
None.
