FLORA OF THE HAWAIIAN ISLANDS. 16f 



Stamens 8, filaments subulate or flattened, often quite short in the fer- 

 tile flowers. Hypogynous disk short, entire or eight-crenulate. Ovary 

 4-celled (the cells opposite the petals) 4-lobed, often umbilicatc ; style 

 central ; stigma 4-lobed. Ovules 2 in each cell, hemitropous. Capsule 

 4-parted, the cocci divaricate, loculicidally dehiscent. Seeds usually 

 2 in each cell, ovoid, with a shining, black testa. Embryo straight, in 

 fleshy albumen ; cotyledons oval. Unarmed trees ; with a heavy odor. 

 Leaves simple, entire, opposite or whorled, coriaceous, very veiny, the 

 veins uniting in a more or less distinct iutramarginal one. Flowers 

 axillary. 



A small genus, peculiar to the Hawaiian Islands (or perhaps one In the Samoau 

 Islands). 

 Leaves whorled; flowers fascicled in the axils on short peduncles. 



Leaves petioled, entirely glabrous, 1. P. clusise/olia. 



Leaves petioled, pubescent beneath, 2. P. sapotirfolia. 



Leaves sessile by an auricled base,. 3. P. auriculxfolia, 



Leaves opposite ; branches glabrous. 



Leaves velvety-villous beneath ; coriaceous, i. P. Kavaiensis. 



Leaves glabrous; rather thin, 5. P. anisata. 



Leaves glabrous, coriaceous, oblong, petioled, 6. P. oblongifolia. 



Leaves glabrous, coriaceous, orbicular, sessile, 1. P. rotundifolia. 



Leaves opposite ; branches liirsute-tomentose. 



Leaves oval or oblong, strongly reticulated and glabrous beneath, 8. P. Sandwicensis. 



Leaves oval, beneath slightly hirsute, 9. P. volcanica. 



1. P. CLUSLEFOLIA Gray. (Enum. No. G6.) A small tree, 20, 

 more or less, high, as are all the species of the genus. Glabrous 

 throughout. Leaves verticillate in fours or threes, rarely opposite, co- 

 riaceous, obovate or obovate-oblong, obtuse or retuse, more or less 

 acute at the base, pale, 2' -3' or more long, 8" -20" wide; veins 

 straight and parallel. Flowers in axillary subsessile clusters, the short 

 pedicels becoming 2" - 4" long in fruit. Calyx lobes ovate, membrana- 

 ceous, obtuse, l" long. Petals ovate-lanceolate, 3" long, wax-colored. 

 Stamens shorter than the petals. Ovary glabrous, four-lobed, shorter 

 than the style which arises from its umbilicate apex : stigmas 4, thick 

 and short. Capsule obtusely 4-lobed, h' or more in diameter. The thin 

 and papery endocarp glabrous within.' Seeds 1 - 2 in each cell, black 

 and shining, l"-2" in diameter. 



Mountains behind Honolulu, and Kaala Mountains, Oahu. Windward slopes of 

 Mauna Kea, and district of Puna, Hawaii. 



2. P. SAPOT^FOLIA H. Mann. (Enum. No. 67.) The young naked 

 leaf-buds hirsute, as in all the species. Branches and inflorescence 

 glabrous. Leaves 4 iu a whorl, elongated-oblong or spatulate-oblong, 

 chartaceous, 4' -9' long, 2' -3' wide, attenuated or somewhat obtuse at 

 the base, on petioles li' long, villous-pubescent beneath, quite glab- 

 rous above. Flowers in axillary sessile clusters, the pedicels 2" - 3"
