A shrub or small tree 5 to 6 m high; branches terete glabrous or in the axils of leaves 

 sparsely white-villose; leaves chartaceous, obovate or obovate lanceolate, acuminate at the 

 apex, cuneate at the base, narrowing into a petiole of 6 to 12 mm, margins serrate- 

 dentate, glabrous on both sides, 4 to 10 cm long, 2 to 4.5 cm wide; flowers in subdivari- 

 eate cymes, 7 to 15 flowered, as long as the leaves or longer; bracts small linear, acute 

 2 to 5 em long, ovary obovoid, glabrous, 3 to 4 mm long; calyx 1 to 2 mm long, shortly 

 5-lobed, sparsely ciliolate; corolla white with purple streaks or pure white, the erect tube 

 narrow cylindrical, 1.5 to 2 cm long, glabrous outside, sparsely pubescent inside, lobes 

 about half the length of the tube or shorter, winged; stamens almost the length of the 

 tube, the filiform filaments somewhat dilated at the base, anthers small, oblong, truncate; 

 style slightly protruding from the corolla, pubescent below, glabrous above; iudusium 

 glabrous, the superior margin sparsely and siiortly ciliate. fruit ellipsoidal, glabrous 6 to 10 

 mm long, 4 to 5 mm thick. 



This species is one of the most common shrubs or often small trees which one 

 is likely to meet everywhere in the lower or middle forest zone. It is in flower 

 nearly all the year round and is quite a conspicuous object in the forest on ac- 

 count of its white flower, which appears to be only a half a flower, though com- 

 plete. It occurs on all the islands of the group from 800 feet elevation up to 

 4000 feet and even higher ; several varieties have been described. Krause in his 

 monograph on the Goodeniaceae of the world distinguishes three varieties of 

 this species: (1) var. pubescens (Nutt.) Krause, from Kohala, Oahu, (2) var. 

 iracteosa Hbd. from Maui, Hawaii, and Molokai, and (3) var. cylindrocarpa 

 (Hbd.) Krause, from Lanai. 



There are many more varieties of this species in the writer's possession, which 

 belong all to shrubs and therefore do not come within the scope of this book. 

 Plate 210 shows a branch from the typical 8. Chamissoniana, as it occurs in 

 the forests of Oahu. 



Here may be recorded another species, the Ohenaupaka of the natives or 

 Scaevola glabra H. et A. This latter plant often reaches a height of fifteen
