With this more limited plan, and with its execution, as far at least as regards the determination of several of the species, I am so little satisfied, that had the publication depended entirely on myself, and related solely to the present essay, I should have deferred it still longer, probably until the return of Captain Parry from the arduous enterprise in which he is now embarked.

I have, however, to express my regret for the delay that has already taken place, as it has prevented the appearance of the valuable memoirs in other departments of Natural History, which have been long ready for publication; and also as it has till now deprived Botanists of the excellent figures so admirably illustrating the structure of the plants selected for engraving, and for which it is hardly necessary to add that I am indebted to the friendship of Mr. Bauer.[1]

It has not been thought necessary to reproduce the engravings illustrative of the plants described in the present memoir; in the Appendix to Captain Franklin's journey; in Mr. Clarke Abel's journey in the interior of China; and in Captain King's survey of the coasts of Australia. For these plates, in all ten in number, the reader is referred to the works in which they originally appeared.—Edit.
