PACIFIC SCIENCE, Vol. Ill, July, 1949 
crevices between boulders of rough lava. Several 
seedlings were collected from beneath one pis- 
tillate plant and one of these was successfully 
grown for 18 months in the cool, humid con- 
ditions of Manoa Valley on Oahu. This fact 
would seem to indicate that the plant is capable 
of considerable adjustment, for the conditions 
under which it grew on Oahu are nearly the 
opposite of those in the original locality. The 
puberulent character of the leaves and their 
shape remained typical after a year and a half 
of cultivation. It flowered twice, producing 
pistillate flowers. Pollination with pollen from 
an Oahu plant (of another species) was at- 
tempted without success. This observation may 
indicate that genetic barriers exist between 
some of the groups.

Description of G audio baud’s material: Upper 
branchlets pilosulose, hairs many, erect, or sub- 
erect, ascending. Petioles 1-3 cm. long, pilo- 
sulose, hairs many, irregularly bending. Leaf 
blades 7.0-9.5 cm. long, 4.0-6.5 cm. wide, 
broadly oval or ovate, rather thickish, tripli- 
nerved or palmate; above with few ascending, 
appressed hairs and tuft of hair at point of 
divergence of principal veins also appressed, 
ascending, below densely pilosulose, hairs irregu- 
larly bending and curving, grayish or whitish, 
rather shiny, 0.8 mm. or more long; on upper 
surface of venation hairs ascending, appressed, 
on lateral surfaces hairs divergent; margin 
entire, base cuneate or sub-obtuse, apex con- 
tracted abruptly or tapering evenly into an 
acute to long-acuminate tip, principal veins 
raised on lower leaf surface. Pistillate flowers 
sessile, calyx pilosulose with many straight, 
ascending, appressed hairs; stigma with one side 
lacking stigmatic hairs. No mature achenes or 
staminate flowers available. 
Description of all material examined: Upper 
branchlets with very many short, erect or sub- 
erect hairs. Petioles 0.8-5. 0 cm. long, averaging 
3 cm. long, with many erect to sub-erect hairs. 
Leaf blades 3. 5-8. 5 cm. long, 2-5 cm. wide, 
averaging 7 cm. long, 4 cm. wide, thin to 
thickish, narrowly elliptic, elliptic-ovate, ovate, 
slightly obovate, oval, or broadly oval, mostly 
triplinerved; above pilosulose with many ascend- 
ing, appressed hairs, tuft of hairs at junction 
of principal veins on upper surface appressed, 
ascending, below densely pilosulose, hairs irregu- 
larly bending and curving, grayish or whitish, 
pilosulose on principal veins and primary 
branches, hairs appressed, ascending, lateral sur- 
faces of veins with or without fringe of hairs 
oriented at approximately 90° to the veins; 
margin entire or rarely a few teeth present on 
very young leaves, base cuneate, rarely sub- 
obtuse or obtuse, apex abruptly or sometimes 
evenly long-acuminate, acuminate, or acute. 
Pistillate flowers sessile, calyx pilosulose with 
many straight, appressed, ascending hairs and 
few shorter, erect, uncinate hairs, beak expanded 
apically or rarely attenuated to four-toothed, 
entire, or laciniate apex; stigma 3-5 mm. long, 
all sides receptive. Achene 1. 5-2.0 mm. long, 
apical portion depressed-conic, separated from j 
basal portion by deep, acute or obtuse con- 
striction, basal portion flat-convex, 2. 5-3.0 mm.
