Pittosporaceae. 
Corvus hawaiiensis or Alala, which pecks open the large woody capsules and 
feeds on the oily seeds within. The crow is peculiar to Kona, Hawaii. Nearly 
80% of all the capsules of this species examined by the writer were eaten out 
by these birds, which are still very common.

This very interesting tree is peculiar to the interior, high plateau of Kauai 
especially the upper slopes of Waialeale. It grows in the swamps and swampy 
forests as well as along streambeds several miles inland from Kaholuamano, at 
an elevation of 4800 to 5000 feet. It is not uncommon in the more open flat 
swamps in company with the thousands of Lobelia macrostachys at this region, 
which is constantly wrapped in clouds. It is a rather curious plant, with a 
short trunk and perfectly straight branches, which are only few, three or four, 
and the large dark green and brown foliage. It is a constant species and grows 
all over the summit of Kauai. It was collected hy the writer first in Septem- 
ber, 1909, and again in October, 1909, in the Alakai swamp near the head of 
Wainiha, and on Waialeale October 20, 1911. The type is 8867 in the College 
of Hawaii Herbarium, Honolulu, T. H. The plant is named in honor of Mr. 
Francis Gay of Kauai, whose kind hospitality and help in exploring the Kauai 
forests the writer was fortunate to enjoy. At the very summit of Waialeale 
in the open bog the writer found a variety of this species perfectly glabrous; it 
was a shrub about 5 feet high, and may be described here as follows:
