The author gives reasons for retaining the genus name Corysanthes R. Br., as against Corybas Salisb., the latter being the valid name according to the International Rules.

From an examination of herbarium material sent by Mr. H. B. Mathews, of Remuera, New Zealand, the author concludes that Corysanthes Cheesemanii Hook. f. is conspecific with C. bicalcarata R. Br.; Pterostylis Matthewsii Cheesem. is P. nutans R. Br.; P. puberula Hook. f. is P. nana R. Br.
