Wawra says of this species that the flowers are cs es this is, however, 
not the case. All Hawaiian Peleae have fertile and sterile flowers with either one 
or the other organ rudimentary, making them appear to be hermaphrodite. The 
male flowers of this species were not known to Asa Gray. 
Wawra in Flora records three forms: fm. a (normalis) from the Waianae 
Mts., fm. 8 (macrocarpa) and fm. y microcarpa. Asa Gray enumerates two va- 
rieties—@ and y, so does Hillebrand. 
The writer has large material of this species from many localities. It is one 
of the most common Pelea on Oahu, as well as on other islands, especially on 
Hawaii in the forests of Puna, near the Voleano Kilauea. 
It is a medium-sized tree reaching a height of 25 to 30 feet in certain localities. 
Specimens from Konahuanui, Oahu, have ovate acute leaves, but also varying 
tremendously, while others from the Waikane Mts., on the windward side of 
ahu, have obovate subsessile leaves. From the same locality the writer col-
