 Embryo not seen.

Araliacea? — On high land, near Waianae, Oahu, some branches 

 with nascent foliage and young flower-buds were gathered from " an 

 Araliaceous tree, twenty feet high," of which, for want of suflicient 

 materials the genus cannot be made out. The following data which 

 the specimens furnish will serve to indicate the tree to future col- 

 lectors in the Sandwich Islands. 



Branchlets slender (for an Araliacea), with a wrinkled and warty 

 bark, nodose with the scars of former petioles ; the bark not pungent 

 to the taste. Young foliage, &c, glabrous. Stipules none. Leaves 

 alternate, on slender petioles which are slightly dilated at the base. 

 Leaves either trifoliolate or pinnately quinquefoliolate ; the deve- 

 loping leaflets ovate or obovate, petiolulate, entire or undulate, 

 mostly less than an inch long. Male flowers somewhat umbellate or 

 fascicled on the divisions of a small paniculate inflorescence, which 

 arises from the base of the leafy shoot of the season : the buds half a 

 line in diameter, short-pedicelled. Calyx four-lobed, or sometimes 

 five-lobed. Corolla globular in the bud, the 4 or 5 petals moderately 

 imbricated in aestivation. Stamens 4 or 5, alternate with the petals : 

 filaments short : anthers oblong, two-celled, incumbent. Ovary abor- 

 tive, so that the calyx appears as if inferior : a minute stylopodium 

 occupies the place of the style or stigmas. Fertile flowers entirely 

 unknown.
