314 MEMORANDA. 
Enumeration of Hawaiian Plants. By II orace Mann. Reprinted from 
the Proceedings of the American Academy of Arts and Sciences, 
vol. vii., Sept. 1866. Issued July, 1867. Cambridge, United 
States : Welsh, Bigelow, and Co. 1867. 
During Mr. Mann's visit to the Sandwich or Hawaiian group, he 
visited five of the larger islands, and brought together a collection which 
ill 
forms the basis of this enumeration. On his return to the United 
States he examined the collections of Wilkes's Expedition and sets of 
specimens gathered by Bemy, Macrae, Gaudichaud, Chamisso, Douglas, 
and Nut toll. But he had no opportunity of seeing the rich collections 
made in the islands bv Nelson, Menzies, and Barclay, which we have 
in London, and which have as yet been examined but partially, so that 
his c Enumeration,' though it is the most complete as yet published, w 
receive considerable addition from the sources indicated. 
Mr. Mann prefaces his ' Enumeration ' by an historical notice of the t 
different botanists whose visits to the islands have contributed to make 
us acquainted with the Hawaiian flora, beginning with David Nelson, 
who, in 1778-1779, accompanied Captain Cook, and ending with 
Hillebrand and Brigham. We observe, however, that he omits to in- 
sert, between the visits of Nuttall and Eemy, the two of H.M.S. 
Herald, an account of which was published in the ' Kew Miscellany.' 
This historical notice is followed by a geographical notice and the 
enumeration of the plants. Omitting for the present the Grasses. 
Mosses, and Hepatica, the author enumerates 796 species, 129 of 
which are Lichens, and 116 Ferns. Many new species and the follow- 
ing new genera are described, viz. Alsinodendron (AlsineaJ, Flaty 
desma (Rutacem), and Brigltamia (Lobeliacece). One of the Araliacea 
is also the type of a new genus. 
We congratulate Mr. Mann on the completion of his useful Enume- 
ration, and trust that when he shall have added the three important 
Orders at present omitted, he will enter into some phyto-geographica 
considerations of the composition of the Hawaiian flora.
