the drawing (Plate X.) of a large frond of Forster's P. scandens instead of the true species, and he has 
misled all subsequent observers. The following is the synonymy of the species:—Pleopeltis pustulata,

This is a very distinct species from P. quercifolium, Linn. (ex spec. typo. in Herb. Burmaum), and is 
well characterized and accurately figured by Bory, though he erroneously referred it to Linnæus's species. 
This has led to so much confusion that I will give the synonymy of P. quercifolium, Linn., as far as I have 
been able to determine it with certainty. Р. quercifolium, Linn. Sp. Pl. ed. 1. p. 1087; Schkuhr, Crypt.

D. Linnæi, which Mr. Baker has properly reintroduced (Syn. Fil. p. 368) as an independent species.
