I OF ARTS AND SCIEIJWES : SEPTEMBER 11, 1866. 143 



The President communicated, by title, the following paper, 

 with some remarks upon Mr. Mann's botanical explorations in 

 the Sandwich Islands. 



Eniuneration of Hawaian Plants. By Horace Mann. 



During a visit to the Hawaian Islands, made for the purpose of study- 

 ing especially the Botany of the Group, and which extended from 

 the 4th of May, 1864, to the 18th of May, 1865, I botanized over five 

 of the largest of these islands, and brought together a collection which 

 forms the basis of the following Enumeration. In its preparation I 

 have been permitted to examine the other collections of Hawaian 

 plants in the Gray Herbarium ; namely, that by the United States 

 South Pacific Exploring Expedition under Commodore Wilkes, — the 

 fullest hitherto made in these islands ; a set of the specimens gathered 

 by Jules Remy under the auspices of the Paris Museum, given by 

 that institution ; some of Macrae's plants, given by the London Hor- 

 ticultural (now Royal Horticultural) Society ; and a 'ievf of Gaudi- 

 chaud's, Chamisso's, Douglas's, and Nuttall's. These materials, and all 

 his own memoranda upon them, were freely offered to my use by 

 Professor Gray, without whose friendly encouragement this enumera- 

 tion would never have been undertaken, and could not have been ac- 

 complished. 



The botanists who have collected at the Hawaian Islands, so far as 

 known to me, are as follows : — 



David Nelson, who accompanied Captain Cook on his third voy- 

 age, and collected at the Islands in 1778- 1779. The plants collected 

 by him are stored at the British Museum, and, excepting a few Lahiatce, 

 have scarcely been examined until recently. 



Archibald Menzies, a most indefatigable botanist and collector, 

 visited the Islands with Vancouver in 1792, 1793, or 1794, or perhaps 

 in each of these years, and made large and valuable collections, mostly 

 on Hawaii. Sets of his plants are in the Hookerian, Smithian, and 

 Banksian Hei'baria. 



Albert Chamisso accompanied Kotzebue in the voyage of Ro- 

 manzoff, and collected principally on Oaliu, late in each of the years 

 1816 and 1817. He published notes and descriptions of new species 

 in the Linncea, in conjunction with Schlechtendal. Frederick 

 Eschscholtz was the physician of the expedition.
