Euphorbiaceae. 



conspicuous in that small area on account of its pale glaucous foliage. The wood 

 is exceedingly heavy, close grained and very hard. The sap wood is red, while 

 the heartwood is black, making a beautiful contrast. The type is no. 10030 in 

 the College of Hawaii Herbarium. 



It is associated with Antidesma pulvinatum, A. platyphyllum, Pittosporum 

 Hosmeri var. longifolia, Maba sandwicensis, Alpliitonia excelsa, Cohibrina oppo- 

 sitifolia, Santalum Freycinetianum, Osmanthus sandwicensis, Tetraplasandra 

 Ilawaiiensis, and many other interesting tree species. 



ANTIDESMA Linn. 



Flowers dioecious. Calyx 3 to 5 lobed. Discus teeth free, rarely united. Male flow- 

 ers: Stamens 2 to 5, opposite the sepals; anthers bent inward in the bud, later erect. 

 The rudimentary ovary small. Female flowers: Ovary 1 very rarely also 2-celled. 

 Style 3, very short, 2 lobed. Stone fruit small often oblique. Seeds without caruncle. 



A genus of trees and shrubs, with more than 70 species in the warmer re- 

 gions of the old world. It is distributed from tropical Africa to Australia, 

 Japan and the islands of the Pacific. 



Two species or probably three are to be found in these islands, with one in 

 the Viti (Fiji) Islands, one in Samoa, and two in New Guinea. The only repre- 

 sentative of the genus in tropical Polvnesia, a doubtful one, is recorded by 

 Hemsley from Admiralty Island. None have so far been discovered in America.

Leaves ovate to obovate or orbicular 8 to 12 cm long, 4 to 10 cm wide, on petioles of 

 about 5 mm, shortly acuminate, glabrous, shining above but punctato papillose, chartaceous 

 to coriaceous, panicles puberulous; male flowers: subsessile along the simple branches of 

 a paniculate rhachis of about 8 cm; bracts conchoid, as long as the calyx or longer; 

 calyx less than 2 mm, puberulous, with 5 to 4 roundish lobes; petals rudimentary, diso 

 glabrous, lobed, stamens 5 or 4, long exserted; ovary rudimentary, with peltate stigmas. 

 Female flowers: pedicellate along the branches of a solitary, axile. paniculate rhachis of 

 5 to 14 cm; bracts linear; calyx less than 2 mm, 5 to 8 cleft; disc small, annular; ovary 

 glabrous; style terminal; drupe reddish or dark purplish, fleshy, compressed, suboblique 

 the osseous putamen irregularly ridged. Cotyledons suborbicular, as broad as the scanty 

 albumen, 2 or 3 times as long as the radicle. 



The Hame or Haa is a very handsome tree, reaching a height of 20 to 30 feet, 

 with a trunk of a foot or more in diameter; the bark is fibrous, deeply corru- 

 gated, and whitish. It has no round crown, as the few branches are rather as- 

 cending and have only a few branches. It is conspicuous by its large leaves, 

 which are bright green and glossy, and is on that account often mistaken for 

 the Maua tree (Xijlosrna Hillebrandii or X. Hawaiiense') , which it resembles
