Beccari and Rock — Pritchardia. 'ij 



Valley on the windward side of Molokai, where it grows in similar locations 

 as Pritchardia GaudicJiandii. It is also cultivated by the natives of Wailau in 

 front of their houses. 



MAUI. 



The island of Maui is composed of two distinct mountain masses, West 

 Maui and East Maui. It has, so far as is known, only three species of Pritch- 

 ardia. The eastern part of Maui is made up of the great mountain mass known 

 as Haleakala, one of the largest extinct craters in the world. This mountain, 

 rising to a height of little over 10,000 feet, is younger than the western part of 

 Maui, which is deeply intersected on all sides by ravines and gorges, the highest 

 points being Puu Kukui, nearly 6,000 feet, and Mauna Eeke, over 4,000 feet in 

 height. Two species of Pritchardia have been found in this region. The mos.1 

 distinct species found on Maui is Pritchardia arcciiia, which occurs on the 

 windward side at an elevation of about 3,000 feet back of Honomanu and Nahiku 

 in dense rain forests. This species, while very distinct, shows a decided relation- 

 ship to Pritchardia lanigera of the Kohala mountains of Hawaii, separated from 

 East Maui by a channel forty miles wide. The other species, Pritchardia glabrata 

 and Pritchardia Forbesiaiia, are restricted to the rain forests of West Maui, the 

 former to the lateral branches of lao Valley, and the latter to the drainage basin 

 of Honokahau immediately below Mauna Eeke, an open bog of over 4,000 feet 

 elevation (see PI. IX, A). It is interesting to note that Pritchardia Forbesiaiia 

 is very closely related to Pritchardia Gaudichaudii so common on Molokai and 

 only a few miles distant from the west end of Maui. Undoubtedly the valleys 

 of Waihee, Honokawai, and Olowalu, of the west end, and the mountains back of 

 Keanae and Kipahulu will furnish additional species, since it has been found 

 that each species is very precinctive indeed, being confined not only to one island 

 but to certain valleys or circumscribed areas. 



LANAI. 



This comparatively small island harbors at least one distinct species, 

 Pritchardia Lanaiensis ; but there is a strong suspicion of a second species occur- 

 ring there, as among the fruits of the above-mentioned species deposited in the 

 B. P. Bishop Museum Herbarium there are some which do not belong to 

 Pritchardia lanaiensis, but belong to an entirely dififerent plant. The mature 

 fruits, which I have carefully examined, are different from any known to me and I 

 designated this otherwise incompletely known species as Pritchardia elliptica Rock. 

 According to the accompanying note it occurs at the eastern end of that island, 

 while Pritchardia lanaiensis grows on the windward side at the head of Mauna Lei 

 gorge and also on the edge of the canyon Nahnku, where I observed a number 

 of individuals.
