tis supra glabris subtus incanis; racemo virgato densifloro; bracteis 

 lobisque calycis subulato-setaceis ; corolla rectiuscula cterulea. — East 

 Maui. Leaves a foot or less in length, only a third or half an inch 

 long. Capsule dehiscent through the short and obtusely conical vertex. 



SccBvolce Polynesia. The collection contains, 



1. Sc^voLA Lobelia, Linn., De Vriese. Coast of all the coral 

 islands, and of the Feejees, &c. 



2. Sc^voLA SERiCEA, Forst., of which S. plumerioides, Nutt., of the 

 Sandwich Islands, is a variety with ample and almost glabrous leaves. 

 Tonga, Samoan Islands, &c. 



3. Sc^vOLA CORIACEA (Nutt.) : fruticosa, decumbens ; axillis bre- 

 vissime barbatis ; foliis parvulis carnoso-crassis obovato-spathulatis in 

 petiolum brevem attenuatis aveniis soepe retusis ; pedunculis axillari- 

 bus uni- (raro tri-) floris ; calycis limbo truncato vel obscure quinque- 

 lobo ; corollie lobis lineari-lanceolatis, alis angustis. — Sandwich Islands. 



Var. a. {S. coriacea, Nutt. in Trans. Amer. Phil. Soc. n. ser. 8, p. 

 253) : cinereo-puberula vel glabella ; foliis integerrimis ; corolla extus 

 glabra vel pilosula, lobis intus piloso-barbatis. — Kauai and Maui, on 

 sand-hills. 



Var. /3. corolla intus imberbi extus foliisque glabris. — Nihau, Remy. 



Var. y. foliis cinereo-tomentulosis apice 3 - 5-denticulatis ; corolla 

 extus pubescente, lobis intus glabris. — Molokai, Remy. — To this spe- 

 cies probably belongs the Sandwich Island specimen referred by De 

 Vriese to S. montana, Labill. ; but that species is an upright shrub, 

 with well-developed calyx-lobes. 



4. Sc^vOLA Gaudichaudi, Hook. & Arn. (non Gaudichaudiana, 

 Cham.), includes S. montana, Gaud., non Labill., and apparently S. 

 Menziesiana, var. glabra, Cham. It will probably prove to be only an 

 extreme form of the following polymorphous species ; but it has a less 

 developed* inflorescence, narrower and somewhat fleshy-thickened, 

 nearly veinless, more entire, and smaller leaves, a more slender and 

 usually glabrous corolla, &c. The flowers of this and the following 

 species are white, not yellow as De Vriese implies. De Vriese's 

 genus Temminchia, founded on these Sandwichian species, is said to 

 differ from Sccevola in the inflorescence not being cymose, nor the fila- 

 ments bearded, nor the fruit fleshy (baccate). But it would be difiicult 

 to find a more purely cymose inflorescence than in these species when- 

 ever the peduncle is several-flowered ; the filaments are equally beard- 

 less in the original and perhaps in every known species of Sccevola, and 

 the mature fruit is a baccate drupe.
