1. Blechnum L.

Blechnum procerum (Forst. f.) Labill. Syn. B. capense Schlect (1825).

J. C. Andersen: Popular Names of New Zealand Plants (Trans. N.Z.I., Vol. 56, 1926, p. 681).

This would appear to be a compound species. One of its forms has the lower pinnae (almost invariably) not narrowed at the base, and stipes very long in proportion to the frond. There is no doubt that the species needs revision, and in the present state of our knowledge it seems impossible to come to final conclusions about some of its forms. Carse submitted characteristic B. capense (as then understood in New Zealand) to Dr. Christensen, who said that it “should probably be named B. procerum”

Blechnum minor (R. Br.) Ckne.

Syn. B. capense var. minor Hook f. (1855).

Blechnum patersoni Mett. (1856)

Syn. Blechnum patersoni var. elongatum Hook. and Bak. 1873.

The type and its variety were originally thought two forms. There was, Cheeseman remarks, “The type which was believed to always have simple fronds, and secondly var. elongatum in which the fronds were pinnatifid…. But it was long since proved that the variety produces simple fronds and B. patersoni has been found with pinnatifid ones, so that the supposed distinction falls to the ground.”
