This plant scarcely differs generically from the following, with which it sufficiently agrees in habit. By Kützing 
it has been erroneously referred to Botryoglossum, from which it is widely separated by its fructification. The 
ceramidia, with which we were unacquainted when the genus was first described, resemble those of Pollexfenia 
pedicellata.

(Harv. in Hook. Lond. Journ. Bot. iii. p. 431. Ner. Austr. p. 21.)
