TYPUS: Kauai, Hanakapiai, Napali Coast, 
in woods, 800 ft., Jan. 2, 1931, H. St.John et 
al. 10,988 (BISH), (st. If. fl. fr.). 
SPECIMENS examined: Kauai, Wahiawa 
Mts., / M. Lydgate (BISH), (st. If. fl.); ex 
Museo botanico Berolinensi, Knudsen 196 
(BISH), (If. fl.). 
There are slight differences between the 
two latter collections and the type which 
came from the north, or Napali, coast of 
Kauai. The specimen from the Wahiawa 
Mountains, collected by Lydgate, consists of 
small snips from a shrub, but when assembled 
these show the stem, stipules, leaves, flowers, 
and young fruit. Only the sepals differ slight- 
ly in having a few ciliolations towards the 
tip. All other parts match well those of L 
maculatum, hence it seems best to keep it 
within that species. 
The collection, Knudsen 196, consists of 
fragments given to Rock from the Hillebrand 
collection in Berlin. It contains five loose 
blades and one loose flower. It was identified 
by Hillebrand as /. longifolium and so cited in 
his flora (1888: 19). The blades are similar in 
texture and general outline to the oblance- 
olate, undulate ones of /. longifolium, but they 
are only 5. 4-9. 5 cm, long, far below the 
dimensions of the former, and are crenate 
instead of merely undulate. The flower differs 
from those of 1 . maculatum only in having the 
calyx lobes slightly longer and narrower and 
glabrous. Rock studied the original sheet 
when in Berlin in 1914 and made an ink 
sketch of it. This shows a large plant with six 
leaves fully outlined, 11-16 cm. long, 3,0-42 
mm. wide, linear-oblanceolate, and like those 
of I. maculatum. Rock also listed as identical 
another specimen, Knudsen 3. 
In view of the fragmentary nature of the 
material and the slight differences, the speci- 
mens collected by Knudsen and by Lydgate 
are, for the present, included within the popu- 
lation limits of /. maculatum. 
The vernacular name ”aupaka” is recorded 
for I. pyrifolium Gray by Hillebrand (1888: 
18) and is the only published record of a 
common name for any of the species. Though 
Hillebrand was a very accurate man and his 
flora is a scientific model, there seems to be 
an error at this point. Recently it was learned 
that, in the library of the Hawaii National 
Park at Kilauea, there was a copy of H. 
Mann’s Enumeration of Hawaiian Plants (1867) 
bearing Hillebrand’s signature. As shown by 
the book plate and the library stamp and ac- 
cession number 25,290, this copy was once 
in the library of the United States Geological 
Survey in Washington. Later it was removed 
and the entry cancelled, and it was sold, 
probably as a duplicate. As the son, William 
F. Hillebrand, lived in Washington and was 
long a staff member of the U. S. Geological 
Survey, it appears that Hillebrand’s annotated 
copy passed to his son, to the Geological 
Survey, then was sold in 1935 to the Hawaii 
National Park. This copy’ has recently been 
loaned to the Bishop Museum, and there it 
has been collated. On the front cover Hille- 
brand wrote his name in ink, and throughout 
the pamphlet made additions in the margin 
in ink or pencil. These are mostly to supply 
the Hawaiian vernacular names, none of
