Alsinidendron trinerve sp. nov. 



Growing on the Kaala Mountains, Oaliu, at an elevation of 

 about two thousand feet. — A glabrous branching shrub, about six 

 feet high. Leaves three or four inches long, and one and a 

 half to two inches wide, of a somcAvhat chartaceous texture, oval 

 or ovate, cuspidate-acuminate, tapering abruptly at the base into 

 a margined petiole about an inch long, and with three strong ribs 

 running from the base to the very apex. Cymes from the axils of the 

 upper leaves, on peduncles an inch or more long. Flowers pendu- 

 lous from the ends of long (3-8 lines) capillary pedicels, somewhat 

 globose in shape, a little truncated at the base, and of a light or 

 whitish color. Sepals four (rarely with a minute internal fifth), about 

 four lines long, a little fleshy at the base, but^ with thinner margins and 

 apex, closely imbricated, the two outer completely enclosing the two 

 inner in the bud. Petals and staminodia none. Stamens ten, shorter 

 than the calyx ; the filaments arising from the margin of a thin peri- 

 gynous disk, and about as long as the oblong-linear emarginate an- 

 thers, which are erect and afSxed by a deeply notched base. Ovary 

 ovoid : styles short, 4-7. Capsule membranaceous (only the imma- . 

 ture seen) and probably not opening by valves. Seeds numerous, 

 borne on a central placenta. (Mann & Brigham, 582. Also Hille- 

 brand, fide Oliver in litt.)
