Araliaceae. 
Tetraplasandra Waialealae is really the only tree of any size at the summit, 
where the rest of the vegetation is stunted. It is associated with Pelea Waia- 
lealae, the Anonia of the natives, Lagenophora mauiensis, Sanicula sandwicensis 
var., Lobelia kauaiensis, Lobelia macrostachys var., Drosera longifolia, Dubautia 
Waialealae, Geranium humile var. Kauaiense, ete. 
It is the second species of Tetraplasandra which has been so far recorded 
from Kauai, and is peculiar to Waialeale, though it may be found along the 
Kaluiti and Kailiili streams a little below the summit. The wood is soft and 
white.

This tree was discovered by the writer on the Island of Lanai and described 
by him under the above name. It is rather small, only about 20 feet high, with 
a trunk of a few inches in diameter. It branches irregularly, and as. it was 
crowded in with other trees it was impossible to form an idea of its general 
aspect. 
It is remarkable in the genus Tetraplasandra for its large inflorescence, 
which, instead of being erect, is drooping, and for its very small flowers. The 
leaves are dull and of a light-green color, making the tree quite conspicuous 
among the dark-leaved Maba, Suttonia, and Sideroxylon, with which it is asso- 
ciated. The tree is peculiar to the Island of Lanai and was seen only in Kai- 
holena Valley, crowded by other trees at an elevation of 2000 feet. Kaiholena 
Valley, belonging to the drier regions of Lanai, is extremely interesting and 
harbors a very multiformous tree flora.
