Dicranopteris linearis var. alternans (Mett.) Holttum

Very similar to var. linearis in texture, shape, and hairiness of the ultimate branches, but lateral branch-systems several times forked, the branches at successive forks alternately unequal about as in var. subpectinata, differing from the latter in larger somewhat hairy ultimate branches of much firmer texture.

Apparently not common, but needs field study; perhaps only a growth-form of var. linearis; from sealevel up to 500 m.
