Bt-eynia.] CXVII. EUPHORBIACE^. 1427 



The genua is gensrally spread over tropical ' Asia and the Pacific Islands ; it ia 

 allied to Glochidion, but readily distinguished by the peculiar male perianth, and by the 

 more baccate fruit. 



Fruiting perianth spreading flat to a diameter of about 3 lines 1. U. cermui. 



Fruiting perianth broadly turbinate or concave, enlarging to about 2 lines 



diameter. Styles very short erect or spreading on the obtuse fruit . . . 2. B. ohlongifoUa. 



Fruiting perianth scarcely enlarged. Ovary and capsule more or less 

 contracted into stipes at the base and crowned with three protuber- 

 ances surrounding the styles 3. B. stiintata. 



1. B. cemua (drooping), MueLl. Art), in DC. Prod. xv. ii. 489 ; Benth. Fl. 

 Austi: vi. 113. A glabrous shrub, with the broad almost orbicular leaves and the 

 flowers of B. stipitata, but the female perianth rather larger at the time of 

 flowering, very shortly broadly and retusely 6-lobed, and when in fruit spreading 

 out quite fiat to the diameter of fully 3 lines. Capsule sessile, globular, without 

 appendages, crowned by the very short styles. — Melanthesa cemua, Done. Herb. 

 Tim. Descr. 155. 



Hab.: Cape York, Daemel. 



2. B. oblongifolia (leaves oblong), Mnell. An/, in DC. Prod. xv. ii. 440 ; 

 Benth. Fl. Austr. vi. 114. " Willgar," Bundaberg, Keys. A glabrous shrub, 

 attaining 10 to 15ft., with slender branches. Leaves petiolate, ovate or broadly 

 oblong, obtuse, ^ to lin. long. Stipules small, rather rigid, acute. Flowers 

 monoecious, the females solitary, with or without 1 or 2 males, the males often in 

 clusters of 2, 3 or more, and the cluster sometimes growing out into a short 

 raceme, with a rhachis of i to 1 line, covered with imbricate stipule-like 

 "bracts. Pedicels usually about 1 line long. Male perianth nearly 1 line long, 

 broadly turbinate, flat-topped with the orifice closed, the stamens quite included, 

 the anthers covering the greater portion of the central column. Female perianth 

 spreading and shortly and broadly 6 lobed, about 1 line diameter when in flower, 

 enlarging to 2 lines under the fruit but remaining concave, not spreading flat as 

 in B. cemua. Styles short, entire, erect or spreading. Capsule sessile, globular, 

 about 3 lines diameter, obtuse, without any protuberances round the styles. — 

 B, cinerascens, Baill. Adans. vi. 344.

3. B. Stipitata (stalked), Muell. Arg. in DC. Prod. xv. ii. 442; Benth. FL 

 Austr. vi. 114. A tall glabrous shrub. Leaves petiolate, ovate or almost 

 orbicular, very obtuse, f to IJin. long. Flowers both male and female usually 

 solitary. Male perianth of B. oblongifolia. Female perianth broadly turbinate, 

 very shortly and obtusely sinuate-lobed, scarcely enlarged although more open 

 under the fruit. Capsule globular, contracted at the base into a stipes sometimes 

 very short sometimes half as long as the capsule, crowned by 3 or more less 

 confluent protuberances forming a fleshy ring round the short styles and about 

 their length, both the stipes and the terminal protuberances already apparent on 

 the ovary at the time of flowering.
