Genus Isodendrion — St. John 
243 
which had been included by Mann. There are 
also some notes,, including some on geo- 
graphic occurrence. Well placed, even with 
No. 14, Isodendrion longi folium Gray, there is 
the marginal note in pencil in Hillebrand’s 
hand, "Aupaka (Kauai).” This is at variance 
with Hillebrand’s own printed record of the 
name "aupaka” for 1. pyri folium which is No. 
13, the species just above in Mann’s Enumera- 
tion. It could be supposed that his hand had 
slipped and the words were written a little 
too low on the page, but he gave Kauai as 
the locale of the name. Gray had described 
1. pyrifolium from Oahu alone, then Hille- 
brand, using a wider species concept, re- 
corded it from Oahu, Lanai, Maui, and (by 
implication) from Hawaii, and Niihau also. 
In this present monographic treatment only 
the Oahu specimens remain in 1. pyrifolium, 
while the specimens from other islands are 
allocated to different species. The only Kauai 
collection known to Hillebrand was by Knud- 
sen, and he classified that as the same as the 
Oahu species /. longi folium. The Knudsen 
specimen is here identified as I. maculatum. 
Mr. Valdemar Knudsen of Waiawa, Kauai, 
was one of Hillebrand’s most active collectors 
and cooperators. He made pioneer explora- 
tions of the forests and mountains of Kauai. 
Since we have, in Hillebrand’s own writing, 
the record that "aupaka” was the name of 
Isodendrion on Kauai, it is apparent that this 
name should go with the Knudsen collection 
from Kauai. Hence, the vernacular name is 
transferred to the new 1. maculatum. 
The species is named from the Latin, 
maculatus, spotted, in allusion to the red- 
spotted fruits.
