back, but not at all spurred. The style, also, is very short, thick, 

 and uncinate-cucullate. In this view, the species may be compared 

 with Viola sarmentosa, of Oregon, from which, however, it is abun- 

 dantly distinct. But if these are the normal flowers, the species 

 must be ranked with the Australian V. (Erpetion) hederacea; and it 

 has a similar mode of growth.

V. eaiile fructicoso erecto; foliis oblongo-ovatis subcordatis acuminatis 

 serrulatis, ramealibus basi nunc acutis; stipulis ovatis lanceolatisve 

 acuminatis sape denticulatis ; calcare brevi late saccate ; antheris apice 

 subulato-appendiculatis.

 V. tracheliifolia, Gingins, 1. c. p. 409. 



Hab. Oahu, Sandwich Islands; on the Kaala Mountains, and in 

 the vicinity of Wailuka. 



Sterns upright, from one to 6 feet high, woody, and from one-eighth 

 to more than half an inch in thickness, branching above, the branches 

 annulate with the cicatrices of former leaves and stipules, glabrous. 

 Leaves ovate, or mostly oblong-ovate, and somewhat cordate, acuminate, 

 serrulate with rather appressed glandular-tipped teeth, glabrous, or a 

 little pubescent beneath when young, membranaceous or chartaceous, 

 veiny; the principal cauline ones from 3 to 6 inches long, mostly 

 subcordate, and not unlike those of Tracheliwm cceruleum; their 

 petioles one or two inches long : leaves of the flowering branches suc- 

 cessively smaller and shorter petioled, merely obtuse or the upper 

 acute at the base. Stipules scale-like in texture, brownish, small ; the 

 lower triangular-ovate, the uppermost lanceolate, acuminate, either 

 entire or beset with a few lacerate or setaceous teeth, which are 

 usually glandular-tipped. Peduncles axillary, half an inch to an 

 inch long, 1-2-bracteolate above the middle ; the bractlets lanceolate- 

 subulate. Flower 6 to 8 lines long. Sepals very little produced at 

 the base, linear-lanceolate ; the two lower sometimes a little broader 

 and shorter than the others. Petals apparently light blue or violet, 

 oblong-spatulate, beardless, nearly equal, the lower one broadly sac-
