Pittosporaceae. 



mm, bracts ovate lanceolate 5 to 8 mm; tube of corolla about 8 mm split up to the upper 

 third, the lobes broadly ovate; stamens as long as the tube, anthers oblong-sagittate; 

 ovary ovoid, densely tomeutose style almost twice as long; capsule bluish-glaucous or 

 colored, subquadrangular, about 3 cm or more in diameter, valves woody, deeply wrinkled; 

 seeds black, smooth or minutely tuberculate. 



This species is a small tree, 15 to 18 feet high, with straight ascending 

 branches, bark white, smooth; flowers cream-colored. This particular species, 

 occurs on the island of Hawaii in the forests of Naalehu, Kau, at an elevation 

 of from 2300 to 4000 feet or more, where it is quite plentiful. It was alsO' 

 collected by the writer on the great plateau of the Kohala mountains of the 

 same island at an elevation of 4000 feet, but not at all common. Its distinctive 

 characteristics are the capsules, which are bluish-glaucous and deeply wrinkled,, 

 as well as the very large foliage, which is, however, exceeded in size by Pit- 

 tosporum Hosmeri var. longifolia.

Leaves chartaceous with strong prominent nerves, obovate oblong, 12 to 24 cm long, 

 4 to 8 cm wide, shortly acuminate, with a distinct petiole of 2 to 4 cm long, dark green, 

 glabrous above, covered with a whitish or golden yellowish pubescence; inflorescence 

 axillary or cauline, densely hirsute with brownish hair, peduncle short, about 8 mm, 

 pedicels 4 mm, sepals scarcely 2 mm, acute, villous, corolla cream colored the lobes about 

 2 mm with a strong median nerve; stamens as long as the tube, style little longer; capsule 

 subglobose 16 mm in diam., glabrous when mature, covered with brownish wool when 

 young, with 4 deep longitudinal furrows; seeds smooth, shiny. 



This is one of the tallest species of Pittosporum, reaching a height of 30 to 40 

 feet, with a trunk of about 10 inches in diameter, which is vested in a smooth 

 whitish bark. It is peculiar to the island of Kauai, where it grows in the 

 forest of Kopiwai, below Halemanu, 3600 feet, as well as at higher elevation. 

 It is not common at Kaholuamano, but was again collected by the writer in Olo- 

 kele canyon and in the woods of Makaweli, elevation 2000 feet. The trees from 

 the lower locality differ from those of the type locality, Halemanu, in the cap- 

 sules, which are wrinkled, but are otherwise the same. The pubescence of the 

 underside of the leaves disappears with age.
