PACIFIC SCIENCE, Vol. Ill, July, 1949 
Type: Forbes 1828-0, Mokuleia, slopes of 
Kaala, April 26-May 16, 1912. (Type deposited 
in Bishop Museum [Ho].) 
Range: Island of Oahu, Waianae Range, in 
dry situations 1,900-2,500 feet altitude. 
Specimens examined 
Data complete: West face of Puu Kalena, 
Waianae Kai, Fosberg 9264 (Ho) ; West branch 
of Waianae Valley at pali near Kolekole Pass, 
Degener 18182 (NY); Puu Kaua, on easterly 
ridge, Cowan 840 (Ho). 
Data not complete: Honolulu, Hillebrand 
(K); Hillebrand, no locality (K); Remy 196, 
Hawaii (almost certainly incorrect locality) 
(P). 
This typical variety may be distinguished 
from dentata by the entire leaf margin and 
the strictly or mostly appressed hair on the lower 
leaf surface. Rarely, dentata has an entire 
margin and then it is only the posture of the 
pubescence which must serve to identify it.

Diagnosis typi: A var. angulata differt in foliis 
marginibus dentatis subtus valde curvati-pilosu- 
losis sericeis.

tion of leaves in Neraudia angulata Cowan var. den- 
tata Degener and Cowan. 
Description of all material examined: Shrub 
1-3 m. tall. Petioles 0. 8-3.0 cm. long; leaf 
blades elliptic, elliptic-ovate, or ovate, margin 
dentate, partly dentate, repand, or rarely entire, 
base cuneate-decurrent to obtuse, apex abruptly 
or evenly long-acuminate or only acute; below 
densely sericeous, hairs sub-erect or erect, geo- 
metrically uneven sheen on lower leaf surface 
not so conspicuous as in preceding, owing to 
more nearly erect hairs, most hairs curving to- 
ward margin apically. 
Type: Cowan 750, Extension of fire-break 
trail, west of Puu Iki, Waianae Range, Oahu, 
December 7, 1947. (Type deposited in Bishop 
Museum [Ho].)

The extent of dentation of the leaves of this 
variety varies considerably but usually leaves 
with some teeth can be found on each plant. 
When a collection is discovered with no den- 
tation it is necessary to observe the posture of 
the pubescence on the lower leaf surface. In 
this variety the pubescence is sub-erect or erect 
and the upper part of each hair is usually curved 
toward the margin. 
Otto Degener recently collected some ma- 
terial of this variety and pointed out its dis-
