ing of several collections under one number) 
(GH, G). 
This typical variety differs from variety 
Helleri principally in its entire leaf margins. 
The different leaf shape and the long-pedicelled 
staminate flowers of variety Helleri serve to 
separate the two varieties. 
Neraudia kauaiensis (Hbd.) Cowan variety 
Helleri Cowan, var. nov. 
Diagnosis typi: A var .kauaiensi differt in 
marginibus foliorum undulatis, petiolis longiori- 
bus, pedicellisque longioribus. 
Description of all material examined: Petioles 
3-7 cm. long, averaging 5 cm. long. Leaf blades 
6.5-12.0 cm. long, 3. 5-5. 5 cm. wide, averaging 
8 cm. long, 4 cm. wide, elliptic to elliptic- 
ovate; above with many very short, appressed 
or sub-erect hairs; margin irregularly undulate, 
base obtuse or sub-obtuse. Pistillate flowers un- 
known. Staminate flowers with pedicels 0.5-2. 5 
mm. long, averaging 2 mm. long, calyx lobes 
3.0-3. 5 mm. long, 1. 5-2.0 mm. wide; filaments 
3-4 mm. long, 0.5 mm. wide; anthers 1. 5-2.0 
mm. long, 0.8-1. 0 mm. wide. 
Type: Heller 2847 (NY), "On Kaholuama- 
noa, above Waimea, October 1-8, 1895,” 
Kauai (NY, P, GH, G). (Type deposited at 
New York Botanical Garden; also sheets at P, 
GH, and G.) 
Range: Known from the type locality only. 
Specimens examined: Only type collection 
available for study. 
Although the material for this group is in- 
adequate, it seems to be a distinct entity to 
which a name should be applied. It may be 
distinguished from variety kauaiensis by its 
irregularly undulate leaves and the presence of 
many long filiform pedicels at each node. No 
pistillate material is available but it is hoped 
that future collections in this locality may re- 
veal the nature of the pistillate plants. 
The name for this group was chosen in recog- 
nition of the outstanding field work accom- 
plished by A. A. Heller in the Hawaiian Islands 
in 1895. His very acute powers of observation 
and awareness of plant differences resulted in 
the description of many new species and in a 
collection of much valuable material.

Description of Gaudichaud’s material: Upper 
branchlets with many short, straight, erect hairs. 
Petioles 1-2 cm. long. Leaves 5-6 cm. long, 
3-4 cm. wide, ovate or oval, thin, palmate; 
above with few, very short, ascending, appressed 
hairs, below puberulent with many very fine, 
more or less erect, very short, straight or slightly 
bending hairs; margin entire, base obtuse or 
cuneate, apex contracted abruptly into an acumi- 
nate or long-acuminate tip. Pistillate flowers 
sessile, calyx pilosulose, hairs many, short, as- 
cending, appressed, and with few erect, uncinate 
hairs intermixed, beak expanded or attenuate 
apically. Achene about 2 mm. long, apical por- 
tion depressed-conic, separated from basal por- 
tion by obtuse constriction, basal portion raised, 
involute at outer margin, about 2.5 mm. in 
diameter. No staminate flowers available. 
Description of all material examined: Vining, 
sprawling, rarely erect shrub 1-3 m. tall with 
a spread of 3-7 m., sometimes clambering over 
adjacent vegetation, main stem up to 5 cm. in 
diameter at base; upper branchlets pilosulose, 
with many short, erect hairs. Leaf blades 3-10 
cm. long, 2-6.5 cm. wide, elliptic, elliptic-ovate, 
ovate, broadly ovate, or oval, thin, palmate; 
above sparsely puberulent, below more densely 
puberulent; margin entire, base usually obtuse or 
sub-obtuse, sometimes cuneate, apex abruptly or 
evenly acuminate or long-acuminate, occasion-
