araliacejE. 7 27 



Hab. Oahu, Sandwich Islands; on the mountains behind Honolulu, 

 at the elevation of 2,000 feet. 



The collection contains only a single specimen of this evidently 

 arborescent plant, with staminate but sterile flowers only. Until 

 additional materials are obtained, it may be provisionally appended 

 to Qastonia, merely because it accords with the Mauritian species in 

 having twice as many stamens as petals, and also pinnate leaves.— 

 Branches stout, marked with very large leaf-scars. Leaves pinnately 

 5-9-foliolate, glabrous, as is the whole plant. Stipules none. Leaflets ■ 

 fleshy and thick, 2 to 3£ inches long, oblong or oval, inclining to obo- 

 vate, obtuse, closely but inconspicuously feather-veined, mostly acute 

 at the base, on a short partial footstalk. Umbels compound, cymose, 

 crowded at the summit of a compressed-angled common peduncle. 

 Bracts, if any, caducous. Calyx-tube (of the sterile flowers) clavate, 

 4-5-angled; the limb very short, truncate, repand. Petals 5, trian- 

 gular-lanceolate, valvate in aestivation, expanding in anthesis, but 

 caducous. Stamens 10: filaments subulate, short: anthers two- 

 celled, oblong, opening longitudinally. Sterile ovary 4:-5-celled, inane, 

 crowned with a very short stylopodium and an abortive entire stigma. 

 Fertile flowers and fruit not seen. 



The collection of M. Gaudichaud, made at Oahu in the Voyage of 

 the Bonite, contains some pinnately compound foliage of another 

 Araliaceous tree, probably a congener of the above, but hardly of the 

 same species..
