in diameter, outer margin plane; seed ovoid 
with constriction in upper part. Staminate 
flowers sessile or with pedicels 1-2 mm. long,

elle de Paris [P].)

Data incomplete: Maui. — East Maui, Hille- 
brand; Kawaihai i’uke, Hawaii, Hillebrand (K) ; 
Hawaii, Remy 196 (in part) (P). Data of last 
two collections are questionable. 
This species was published only as a plate 
in the volume of drawings of plants collected 
by Gaudichaud on his second voyage, on "La 
Bonite.” He did not describe the group but 
the publication of the plate legitimizes the name. 
As a result of his failure to supply a descrip- 
tion, faulty interpretation of the group by sub- 
sequent authors has been the rule. It was not 
until his material was studied that the writer 
was able to apply the name properly. Hille- 
brand misapplied the name to what is named 
here N. angulata and Wawra also misunder- 
stood the group, applying the name to N. kau- 
aiensis. Although Hillebrand’s type is not avail- 
able, it is likely from the description that his 
N. Kahoolawensis was a Kahoolawe represen- 
tative of N. sericea or, at least, closely related. 
The variability in this species is such that a 
much greater mass of material is necessary 
before the group can be understood fully. 
Adequate material may reveal sub-specific en- 
tities, for within the material available is some 
which does have a somewhat different aspect 
but close examination has failed to reveal any 
natural bases of segregation. Intensive collect- 
ing on Maui, Molokai, and Lanai is necessary 
before a proper evaluation of the group can 
be made. The two collections from Lanai have 
petioles which are half as long as the leaf 
blades while the leaves of the Maui and Molokai 
material have petioles one-third or less as 
long as the leaf blades. In the Maui and Molo- 
kai material the main parts of the venation 
are outlined by very many sub-erect hairs placed 
almost perpendicularly to the lateral surfaces 
of these veins. Not all of the Lanai material 
shows this fringe of hairs. These differences do 
not seem important enough to justify another 
group unless subsequent collections show these 
characters in addition to others of more sig- 
nificance.

Rock 8647 and part of Rock 8648 are col- 
lections of a staminate plant from Maui and 
are notable because of the occasional presence 
of a few teeth on the margin of young leaves. 
In the Rock collection, used here for Figure 
18, the achenes have a constriction which is 
more obtuse than is typical. In Forbes 2324-M,
