Pittosporaceae. 
Wawra in Flora writes that P. acuminatum, described by Mann, may belong 
to the group of P. terminalioides. This view the writer does not share with 
Wawra, but he thinks it to be closer to P. insigne var. 8 Hbd. However, it is 
quite a distinct species. Specimens were collected by the writer on Kauai, to 
which island the tree is peculiar. It is plentiful at Halemanu, and Kaholua- 
mano at an elevation of 4000 feet, where it grows in the drier forests or on ex- 
posed ridges. It was also observed above Makaweli at an elevation of 2000 feet. 
Specimens from this locality differ somewhat from those of the higher elevations 
in being much stouter, and in having coriaceous instead of chartaceous leaves.

A tree of 15 to 18 feet in height, occurring in the rain forests of Oahu, espe- 
cially in the Koolau range. It is a very distinct and not variable species, as its 
characteristics are quite constant. It is a rather handsome, though somber, 
plant, and is conspicuous from a distance on account of its dark green foliage. 
It is quite common on the upper slopes of Konahuanui, elevation 3000 feet, and in 
the mountains of Punaluu, Waiahole, and Waikane. In the upper forests of 
Oahu it takes the place of P. glabrum, which grows up to 2000 feet elevation. 
Norace Mann’s specimens came from Kaala Mt., Waianae range.

A small tree occurring at the eastern end of Oahu in Waker Valley. Hille- 
brand also describes a variety B. acutisepala from the same region, evidently a 
slight variation. 
The species comes very close to P. glabrum and is perhaps only a form of it.
