This very interesting species, which seems to be related to Hillebrand’s var. B 
of Pelea sapotaefolia as far as capsules are concerned, oceurs in the park-like 
Kipuka Puaulu near the Volcano of Kilauea, on Hawaii, at an elevation of 4000 
feet. It is a conspicuous tree on account of its peculiar branching habit, ex- 
ceedingly large leaves, and very large cuboid capsules. It is quite plentiful in 
company with Pelea volcanica, Pelea clusiaefolia, Xanthoxylum, Sapindus sapo- 
naria, Suttonia and other trees. It was discovered by the writer in July, 1911, 
when he collected his type material, which is no. 10216 in the College of Hawaii 
Herbarium. Named in honor of Dr. A. Zahlbruckner, Director of the Botanical 
Museum in Vienna.

This exceedingly interesting species was discovered by the writer on the lava 
fields of Mt. Haleakala on the southern slopes, in the district of Kahikinui, on 
Maui. The particular locality where this tree occurs is called Auahi, and is sit- 
uated at an elevation of 2600 to 3000 feet. It is the richest botanical section in 
the whole Territory, with the exception of Puuwaawaa on Hawaii. 
The species in question is a good-sized tree 30 to 40 feet in height, with a 
trunk of over one foot in diameter, which is clothed in a gray smooth bark. The 
tree is badly attacked by a lichen, a species of Usnea, probably australis, which 
Seems to check the growth of the trees; they are literally covered, trunk and 
branches, with this ungainly looking Hienen 
€ tree was discovered during November, 1910, when the first specimens were 
collected (no. 8646 flowering and fruiting). During the first part of March, 
912, the writer revisited that locality for the purpose of collecting additional 
material and also to secure photographs. Many trees were then in flower, and
