with 2-several parietal placentas; style often with clavate stigma protruding. Fruit coriace- 
ing stipules. Flowers pasuaiiuslty very large, terminal or axillary, white, yellow or purple. 
The genus consists of about 70 species which are distributed over tropical 
Africa, Asia and Australia. About 10 species have been described from the

_ Branches dichotomous, densely foliose, scarcely glutinous at the ends; leaves on short 
petioles of 4 mm, ovate, shortly acuminate, chartaceous, with prominent straight nerves, 
shining above, papillose and puberulous when young; stipules triangular or truncate; 
¥ ° var 
rl se, with 4 faint 
lines, about 2.5 em in iameter, coriaceous, indehiscent, tipped with the contracted limb of 
the calyx, 1-celled, with 4 (or 3 or 5) parietal placentas projecting about 4 mm from the- 
pergameneous endocarp; seeds many in a yellowish pulp, horizontal, flattened, obtusely 
3 or more angled. 
The Nau is a small tree, reaching a height of 15 to 18 feet, or is even smaller 
when it is a shrub. It has a trunk 6 to 8 inches in diameter and is vested in a 
smooth or slightly roughened bark. The fiowers are of a beautiful white and 
very fragrant and would be worthy of cultivation on that account. During the 
month of March the trees are usually loaded with the globose fruits, which turn 
black when mature. Hillebrand remarks that the fruits do not open on the 
tree, though the writer saw them split into several divisions on most of the 
trees on Molokai. 
The Naw is peculiar to the very dry districts on the leeward sides of the 
islands, and is especially common on Molokai, where it forms the remnants of 
the dry forest on the slopes of Mauna Loa which forms the west end of that 
Island. The trees on Molokai are taller than on the other islands. It associates 
with the Keahi, Chrysophyllum polynesicum, Kokia drynarioides, Reynoldsia 
Sandwicensis, Xylosma H illebrandii, Nototrichium sandwicense, ete. On Lanai 
it is also very common in the Valleys of Mahana and Kaiholena, as well as on 
the slopes of the Kaa desert, where it can be found with some of the above 
mentioned trees and also with Bobea sandwicensis, Nothocestrum sp., Osnanthus
