FLORA OF THE HAWAIIAN ISLANDS. 241 



with stout branches marked with very large leaf-scars ; when young 

 hirsute, as is the inflorescence, with strigose hairs, at length glabrate. 

 Leaves opposite or in verticils of 3, ovate-oblong or narrowly oblong, 

 4' -8' long, li'-3^' wide, acute, tapering at the base into the petiole, 

 coriaceous, feather-veined from the stout midrib, closely serrate with 

 fine and incurved callous teeth, glabrous above, the midrib and veins 

 beneath strigosely hairy, especially when young. Petiole 6" -20" 

 long, very much dilated at its insertion. Primary divisions of the 

 cyme subtended by foliaceous bracts, 1' or less in length. Pedicels 

 l"-3" long. Bractlets minute and caducous. Fruit 3" in diameter, 

 bright red when ripe. Seed 3" long. Some botanists distinguish two 

 species, one with opposite and the other with verticillate leaves (B. 

 pellucida Gaud.), but the other characters are hardly sufficient. 



Not uncommon in mountain woods. 



ORDER XXVIII. DROSERACE.E. 



Small herbs, growing in swamps, usually covered with gland- 

 bearing hairs ; with the leaves rolled up from the apex to the base in 

 vernation (circinnate) : stipules none. Calyx of 5 persistent sepals. 

 Corolla of 5 petals, withering and persistent, convolute in a3Stivation. 

 Stamens 4-20. Styles 3 to 5, distinct or nearly so, and each two- 

 parted (so as to look like 10 styles), and these divisions sometimes 

 two-lobed or many-cleft at the apex. Fruit a 1-celled capsule, opening 

 loculicidally by 3 to 5 valves, with 3 to 5 parietal placentae. Seeds 

 usually numerous. Embryo small, at the base of cartilaginous or 

 fleshy albumen. 



1. DROSERA L. 



Stamens 5. Styles 3, or sometimes 5, deeply two-parted, so that 

 they are taken for 6 or 10, slender ; stigmatose above on the inner 

 face. Pod globular or oblong. -^ Low perennials ; the leaves (with 

 reddish gland-bearing bristles) all in a tuft at the base ; the naked 

 scape bearing the flowers in a 1-sided raceme-like inflorescence, which 

 nods at the undeveloped apex, so that the fresh-blown flower (which 

 opens only in sunshine) is always highest. 



A large genus, distributed throughout most of the world. The Hawaiian species the 

 only one known from the Pacific Islands; though there are many species in extratropical 

 Australia. 



1. D. LONGIFOLIA Linn. (Enum. No. 129.) Leaves spatulate- 

 oblong, tapering into the long, rather erect naked petioles; seeds 

 oblong, with a rough close coat. Flowers white. Plant raised on its 

 prolonged caudex when growing in water. 



Leeward verge of the mountains of Kauai. To be looked for on the mountain of 

 West Maul: rare. Common in North America and Northern Europe in boggy places.
