Hab. Kaala Mountains, Oahu, Sandwich Islands. 



Stems 6 feet high, with rather few very stout branches, roughened 

 with the cicatrices of fallen leaves, and above with the persistent 

 stipules. Leaves alternate, approximate at the summit of the branches, 

 of a coriaceous texture, entirely glabrous, as is the whole plant, 6 to 8 

 inches long, li to 2 1 inches wide, obovate-lanceolate, varying from 

 obovate-oblong to oblong-lanceolate, somewhat acute or acuminate, or 

 rarely obtuse at the apex, below tapering to an acute base, veiny, and 

 with the veinlets reticulated, the midrib very prominent underneath; 

 the margins obscurely repand-undulate, or obsoletely and sparingly 

 serrulate. Petioles i to U inches long. Stipules geminate, subulate- 

 triangular from a broad base, glabrous, carinate with a thickened axis, 

 and with somewhat scarious margins, appressed, persistent long after 

 the leaves have fallen. Flowers axillary, solitary, on very short 

 drooping pedicels, which are bibracteolate next the base, and only 

 one or 2 lines long. Calyx of 5 nearly distinct, ovate and glabrous 

 sepals, quincuncially imbricated in aestivation, not at all produced 

 at the base, scarcely a line long, persistent. Corolla hypogynous or 

 obscurely perigynous, regular, apparently white, scarcely 3 lines long: 

 petals 5, linear-spatulate, connivent for two-thirds of their length into 

 a tube, the upper and dilated portion spreading, convolutely imbri- 

 cated in aestivation, as in Violece, marcescently persistent. Stamens 5, 

 hypogynous or obscurely. perigynous, alternate with the petals and 

 much shorter than they, scarcely exceeding the ovary, all similar, 

 entirely unconnected, glabrous. Filaments subulate-linear, flattened, 

 about the length of the anthers which terminate them, destitute of
