A new species of Pritchardia 
JosepH F. Rock 
(WITH PLATE 2I AND ONE TEXT FIGURE) 
| The genus of palms, Pritchardia, is represented in the Hawaiian 
Islands by eleven species, including the new species treated in 
this paper. Originally, there were only two species known from 
these islands, Pritchardia Gaudichaudii Wendl. and Pritchardia 
Martti Wendl. 
For several years I have carried on, on all the islands of this 
group, thorough botanical explorations; these have brought to 
light several new species of Pritchardia, most of which have been 
described by O. Beccari. Kauai has furnished two species; 
P. minor and P. eriophora; Maui, one species, P. arecina; Oahu, 
one species, P. Rockiana; and Hawaii, two species, P. eriostachya 
and P. Beccariana, the last (which is the handsomest of all) being 
here described for the first time. Beccari had described pre- 
viously P. Hillebrandii from Molokai, P. lanigera from the Kohala 
Mountains, on Hawaii, and P. remota from Bird Island (Moku 
Manu), northwest of Kauai. 
During a sojourn at the Volcano of Kilauea with my friend, 
M. L. Copeland, whom I take this opportunity to thank for his 
kind assistance, we discovered this handsome species in the humid 
forests of Glenwood. I was at once struck by the extraordinary 
size of this palm, its peculiar inflorescence and large globose 
fruits. We felled one tree and thus obtained complete specimens, 
some of which I forwarded to my friend, Dr. O. Beccari, with whom 
I had had long and interesting discussions of our Hawaiian palms 
while in Florence less than two years ago. He pronounced the 
palm a very distinct species but asked me, as he was occupied 
with other work, to describe it. With his consent I have taken 
the liberty of naming this beautiful species in his honor. 
I believe that the Hawaiian Islands still harbor other species of 
Pritchardia, especially Lanai and the Island of Oahu; future
