Kalmku and Waialua; the writer met with it in Niu Valley where it is quite 

 plentiful at an elevation of 2000 feet. Hillebrand records it also from Wailupe 

 Valley. 



OLEACEIAE:. 



The family Oleaceae, which consists of about 370 to 390 species, inhabits the 

 temperate, subtropical and tropical regions of the earth, especially in East India, 

 where some of the genera like Jasminum and others are rich in species. Only 

 about 12 species belonging to this family occur in Europe ; in Polynesia and Aus- 

 tralia about 26 ; in America and Africa each about 46 species. In the Hawaiian 

 Islands the family is represented by the genus Osmanthus with a single species. 



OSMANTHUS Lour. 



Flowers hermaphrodite, polygamous or dioecious, calyx short, 4 toothed or 4 lobed. 

 Tube of corolla short. Stamens 2, rarely 4, with short filaments inserted on the tube of 

 the corolla and enclosed by the same. Anthers laterally dehiscing. Style short. Stigma 

 small, entire or 2-lobed. Shrubs or trees with evergreen leaves. The small flowers are 

 arranged on axillary simple or compound racemes. 



The genus Osmanthus with its 10 species is distributed in South Asia, East 

 Asia, Polynesia and North America, with one species Osmanthus sandwicensis 

 (A. Gray) Knobl. in the Hawaiian Islands.

A large tree often 20 in high, quite glabrous; leaves pale underneath, darker above, 

 coriaceous elliptico-obloiig or lanceolate acute, or acuminate or obtuse, 7 to 15 cm long, 

 2.5 to 7 cm wide, on petioles of about 12 mm; racemes axillary tomentose, short; flowers 

 hermaphrodite; calyx obtusely 4-toothed; corolla about 4 mm, pale yellow, rotate, deeply 

 4 parted; anthers always 4, alternate with the lobes of the corolla and as long as the 

 latter (in the writer's specimens) sessile on the short tube, oblong obtuse; ovary conical, 

 elongate, stigma subsessile, 2-lobed; drupe ovoid, peaked or obtuse, 12 to 22 mm long, 

 bluish-black, when mature rather dry, but the exocarp somewhat fleshy and staining, 

 with an osseous putamen and a single seed; embryo straight in the axis of horny albumen, 

 the obtuse cotyledons as long as the superior radicle. 



The Pua or Olopua is one of the most common Hawaiian trees, but rarely in- 

 habiting the rain forests or even their outskirts. It is more confined to the 

 lower forest zone, especially on the leeward sides of all the islands, and is usually 

 the predominating tree on the lava fields of Hawaii. The Pua, like all Hawaiian 

 trees, is very variable and only a trained eye can at first glance decide if it 

 is the Pua or not. The leaves are often very large and again very small, as in 

 the Molokai specimens, which have elliptical lanceolate leaves, while those of
