Genus Ner audio . — COWAN 
255 
Range : Oahu, Punaluu region of Koolau 
Range in upper rain forest. 
Specimens examined: Pig-God Trail, Puna- 
luu, Degener 18184 (NY), 17117 (NY); Pu- 
naluu, Webster 1603 (U. of Tex.). 
This variety is similar in appearance to variety 
uncinata but differs in its complete lack of un- 
cinate hairs on any plant part, by its staminate 
flowers borne on pedicels, and by the presence 
of many rather long hairs scattered over the en- 
tire lower leaf surface. In this latter character 
it resembles variety pubescens but differs in its 
smaller calices, by the depressed-conic apical 
portion of the achene, and by its usually tripli- 
nerved leaves. It is remarkably similar to variety 
melastomae folia but the long hairs all over the 
lower leaf surface and the lack of uncinate hairs 
on any plant part separate it from this variety. 
Variety Gaudichaudii appears to be most closely 
related to variety melastomaefolia. 
This variety is named in honor of Charles 
Gaudichaud, one of the most illustrious botanical 
travelers of the early exploratory period of the 
Hawaiian Islands. He described many genera 
from these islands and the genus Neraudia was 
one of them. He is also the author of three of 
the species assigned to the genus. 
Neraudia melastomaefolia Gaud, variety pal- 
lida Cowan, var. nov. 
Diagnosis typi: A var. melastomaefolia differt 
in foliis subtus glabris, pallidissimis, floribus 
sessilibus, rostro calycis ad apicem plerumque 
expanso. 
Description of all material examined: Upper 
branchlets sub-glabrous with few, straight, as- 
cending, appressed hairs. Petioles 1-3 cm. long, 
glabrous or sparsely pilosulose with few, ascend- 
ing, appressed hairs. Leaf blades 6.0-7. 5 cm. 
long, 1. 5-3.0 cm. wide, elliptic, oblance-elliptic, 
or somewhat obovate, thin, palmate; upper sur- 
face with very few, ascending, appressed hairs, 
under surface glabrous or with few hairs on 
venation; margin entire, base narrowing, cu- 
neate or sub-obtuse, apex abruptly or evenly 
acuminate or long-acuminate. Pistillate flowers 
sessile, calyx with few ascending, appressed 
hairs, beak expanding apically or sometimes 
attenuate, four-toothed; stigma 4-7 mm. long 
and receptive on all surfaces or stigmatic hairs 
sometimes absent from one side. Achene (ma- 
ture ? ) about 1 mm. long, apical portion hemi- 
spherical or elongate-hemispherical without con- 
striction from basal portion, outer margin of 
basal portion plane, about 2 mm. in diameter; 
seed ellipsoid. No staminate flowers available. 
Type: Forbes 2363 -M, ridge upper part of 
Olowalu Valley, Maui, May 14, 1920. (Type 
deposited in Bishop Museum [Ho}.) 
Range: Island of Maui, western part. 
Specimen examined: Forbes 2470-M, up Olo- 
walu Valley and up right-hand side on ridge, 
May 23, 1920 (Ho). 
The material representing this group is so 
scanty that its evaluation and proper position in 
relation to other groups are not entirely clear. 
The group is recognizable and therefore is 
named in order to call it to the attention of 
future collectors. It may be separated by the very 
pallid appearance of the lower leaf surface 
when dry and the usually expanded beak of the 
pistillate calyx. (See Fig. 20 for distribution.) 
Neraudia angulata Cowan, sp. nov. 
Diagnosis: Frutex 1. 5-3.0 m. altus; petiolis 
0.8-3. 0 cm. longis, perbreviter pilosis, laminibus 
6.5- 13.0 cm. longis, 3. 5-5.0 cm. latis, ellipticis 
vel elliptico-ovatis vel ovatis tenuibus supra 
adpressi-pilosulosis infra valde curvati- vel ad- 
pressi-pilosulosis sericeis marginibus integris vel 
partim dentatis vel dentatis ad basim cuneatis 
vel sub-obtusis vel obtusis ad apicem gradatim 
vel abrupte longi-acuminatis aliquando tripli- 
nervatis. Floribus femineis sessilibus, calycibus 
angulatis valde adpressi-pilosulosis et erecti- 
pilosulosis, rostro calycis ad apicem contracto 
acute 4-dentato, stigmate 2-8 mm. longo 
uno latere sine pilis receptivis. Achaeneis

basim sine constrictione, parte basali crasso 
1. 5-2.0 mm. diametro marginibus exteri- 
oribus in sicco nonnihil involutis et angulatis,
