Araiiaeeae. 



Leaves 36 to 100 cm long, composed of 15 to 21 leaflets varying greatly in size 

 and shape, usually ovate oblong 8 to 21 cm long, 4 to 11 em wide, cordate, truncate or un- 

 evensided at the base, acuminate at the apex, the longest pair of leaflets at about the middle 

 of the leaf, the lowest pair the broadest but shorter, on short petioles in the smaller 

 leaf-forms, and on petioles of often 25 mm in the large leaf forms, glabrous above, fur- 

 furaceous below; panicle very large almost one meter long (in the Kau, Hawaii, speci- 

 mens, but about 36 cm in some of the Maui specimens) rising from a common rhachis of 

 sometimes 15 cm, with 8 drooping rays, each ray often 7.5 dm long, covered with a brown 

 tomentum, the secondary branches 4 to 10 cm long, alternate, the flowers racemose and 

 subumbellate on pedicels of about 1 cm, bractg short triangular; calyx small with an 

 undulate border; petals 6 to 8, 12 mm long, lanceolate, cohering, but finally free; stamens 

 6 to 8, anthers white; drupe ovoid to subglobose, ringed with the calyx border above the 

 middle, stigmas 2 or 3 or 4, slightly raised or sessile on a conical disk; pyrenae coriace- 

 ous inseparable. 



The Ohe ohe of Maui and Hawaii is like that of Kauai, a stately tree 50 to 60 

 feet and sometimes even 80 feet in height. It has a straight bole for 30 feet or 

 more, with few stout ascending branches. The trunk, which is clothed in a whit- 

 ish-gray smooth bark, is often a foot or more in diameter. The tree was first 

 described by H. Mann, who collected it on the Island of Lanai, recording it as 

 a small tree 12 to 20 feet in height. It has since been found on Maui and Ha- 

 waii. It is, however, still most numerous on the southeastern and strictly south- 

 ern slopes of Mt. Haleakala, Island of Maui. In the former locality above Ulu- 

 palakua it is the only species alive, as can be seen in the picture, all the rest of 

 the vegetation having been killed by cattle, goats and sheep. 



On the lava fields of Auahi, district of Kahikinui, the writer found some very 

 big trees in company with Pelea muUiflora, Bohea Hookeri, Alectryon macro- 

 coccus, Xanthoxylum sp., Tetraplasandra meiandra, and many others. It is more 

 or less peculiar to the dry districts, but is also not uncommon in the rain forest 

 on the northeastern slope of Haleakala along the Kula pipe line trail, especially 

 on the crater of Puukakai at an elevation of about 4500 feet. 



On Hawaii it has been found by Hillebrand in the dry district of Kawaihae- 

 iuka, but could not be located during a visit made by the writer in that locality, 

 though the writer was fortunate, however, to find it in the forests of Hilea in 

 Kau, the most southern point on the Island of Hawaii, at an elevation of 2000 

 feet. In this latter locality occur the biggest trees of this species, while in the 

 Kaiholena Mountains, elevation 4000 feet, of the same district, the trees are 

 smaller and resemble the description (outward appearance) given by Mann of 

 the trees which he found on Lanai. 



The wood of the Ohe ohe is rather soft and of no particular value. It is a 

 hardy tree and can stand the ravages of cattle and other enemies better than any 

 other Hawaiian tree.
