Hab. Sandwich Islands : in the forests and the bullock plains on 

 Mouna Loa and Mouna Kea, Hawaii (where it was discovered by 

 Menzies). Var. (3. District of Waimea and Hilo, Hawaii; and in 

 the mountains of Kauai. (Also collected, in fruit, by Gaudichaud.) 



A shrubby species, the erect stems apparently of considerable height : 

 a short truncheon of a stem in the collection is almost two inches in 

 diameter ! The younger branches, leaves, &c, are tomentose-pubescent, 

 apparently not glandular nor viscous, flexuose, unarmed or frequently 

 aculeolate with small and straight bristly prickles, at length glabrate. 

 Stijjides filiform or setaceous, 3 or 4 lines long. Leaves trifoliolate. 

 Leaflets ovate, acuminate or acute, with an obtuse or truncate base, 

 pinnatifid-incised or very deeply doubly toothed (the close teeth sharply 

 pointed), membranaceous, strongly pinnately veined, the lower surface 

 softly and usually densely tomentose, the upper glabrate with age; the 

 lateral leaflets slightly petiolulate, U to 2 inches long; the terminal 

 one long-petiohdate (the stalk half or two-thirds of an inch long), 2* 

 to 3 inches in length, occasionally subcordate. Peduncles 1-S-floivered,, 

 axillary and terminal, solitary or in pairs, short ; when branched the 

 pedicels an inch or less in length, tomentose, unarmed. Calyx 

 flattish, more or less tomentose externally; the short tube sparingly 

 setose-prickly; the lobes ovate, entire, 6 or 8 lines long, tapering into a 

 slender and long acumination, as long as the broadly ovate petals, 

 which are of a red or bright purple colour, and apparently as showy 

 as those of B. odoratus. Stamens and pistils very numerous. Recep- 

 tacle rather hairy. Ovaries sparsely hispid with a few glandular-
