 Branclilets with the leaf-stalks, inflorescence and the exterior of the flowers eanescent 

 with a soft tomentum; leaves alternate, exstipulate, 3 to 4.5 em long, pinnately 5 to 7 folio- 

 late; leaflets oblong or elliptical 10 to 17 cm long and 5 cm or more in width, obtuse at both 

 ends, entire, coriaceous, glabrous above, densely canescent-tomentose underneath, the ribs 

 hirsute; peduncle terminal stout, bearing an ample and open panicle of compound or de- 

 compound umbels; peduncles and pedicels articulate, densely tomentose; calyx tube cup- 

 shaped, the truncate limb very short, entire; petals 5 to 8 tomentose as is the calyx, 

 cohering at the apex, 6 to 8 mm long; stamens 4 times as many as petals or less in one 

 circle, recurved; ovary 7 to 13 celled; the apex crowned with a short and conical stylopod 

 which bears an obscurely 7 to 13 rayed stigma; ovules solitary; fruit a globose baccate 

 drupe 1 cm in diameter, many ribbed when dry, containing 7 to 13 flat chartaceous com- 

 pressed pyrenae. 



The ohe, not to be mistaken for the ohe of the lowlands, is a beautiful tree 

 with a broad, flat crown reaching a height of 40 to 80 feet, with a trunk of 1 to 2 

 feet or more in diameter. The writer met with huge trees in Kona, Hawaii, in 

 the semi-wet forest, overtowering the tallest Ohia trees. The bark is whitish and 

 more or less smooth. 



It can be distinguished from afar on account of its large pinnate leavtis, 

 which are 1 to 1^ feet long, having from 5 to 9 oblong leaflets, which are light- 

 green above and pale-ocher colored underneath, due to a dense tomentum. The 

 flowering panicles are often more than one foot long, bearing umbellate racemes 

 along umbellate and racemose tertiary and secondary branches. The globose 

 fruits become many-ribbed when dry. 



The ohe inhabits the drier as well as very wet regions and is not uncommon 

 in the valley of Wailau, Molokai, where it grows on the steep pali or cliff covered 

 with tropical verdure. On Eanai, from which island it had not been been re- 

 corded previously, it can be found near the summit ridges of Haalelepakai and 

 Lanaihale, at an elevation of 3000 feet, and also on Mahana ridge. 



On Maui it growes above Kaanapali, and on Hawaii it is found in the rain 

 forests of Puna and semi-wet forests of Soiith Kona, together with Xylosma, 

 Pelea, etc. 



Its associates are usually species of Straussia, Bobea, Metrosideros, Cheiro- 

 dendron, and such as are peculiar to the rain forests.
