Description Ochrosia compta is a small tree ranging in height from 10 to 32 feet. The leaves are 4 to 6 inches long and up to 2 inches wide. There are 2 to 4 leathery leaves growing from each node. The leaves are lighter green on the lower surface with a prominent midrib. Like other plants in this family, Ochrosia compta has milky sap. The fragrant, yellow flowers occur in small clusters at the ends of the branches. The 5 petals of the tubular flowers are spiraled. (Wagner 1990) |

Habitat and Geographic Range Ochrosia compta is an endemic Hawaiian tree found in the Wai'anae and Ko'olau Mountains of O'ahu and on the Pelekunu Trail, Wailau Valley, and Kahanui on Moloka'i. It is found scattered in gulches and on ridges in dry and moist forests at elevations ranging from 975 to 1625 feet. (Wagner 1990) |

Propagation by Seeds The 1 inch long fruits of Ochrosia compta are fleshy, pointed at both ends, and have a smooth surface. They are yellow to dark purple when ripe and often occur in pairs. Wooliams reports that untreated fresh seeds of this species germinated in 2 weeks. These seeds had been collected in October and were sown in "Jiffy 7" peat pots. However, the seeds were collected on Kaua'i so may have been from another species of Ochrosia. In his work, Obata found that untreated seeds of this species has a germination rate ranging from 5 to 10%. (Obata 1967; Wagner 1990; Wooliams 1972) |
