1401 CXVII. EUPHOEBIACEiE. [Beyeria. 



rudimental ovary ; anthers with 2 distinct parallel cells opening outwards longi- 

 tudinally in 2 valves. Female flower: Calyx-segments thicker and narrower 

 than in the males, often enlarging after flowering. Ovary 8-celled, entire, with 

 1 ovule in each cell ; stigma sessile, broad,' entire or 3-lobed, peltate and flat or 

 more or less calyptriform and almost conical, more rarely deeply 3-lobed. Cap- 

 sule 3-celled, 3-seeded, or rarely oblique and 1-seeded by abortion. Seeds oblong, 

 smooth, earunculate. Embryo narrow-linear, the cotylebons longer but scarcely 

 broader than the radicle. — Shrubs often more or less glutinous, with alternate 

 leaves, usually narrow, with recurved or revolute margins, white underneath with 

 a close stellate pubescence. Flowers small, axillary, the males solitary or in 

 clusters of 2 or 3, rarely racemose, the females solitary. 



The genus is limited to Australia. 



Sect. I. — XSubeyeria. — Anthers twice as long as broad, adnate to an entire or scarcely 

 lohcd eoniectlve. Stigma entire or scarcely lobed. 



Leaves oblong lanceolate or broadly linear, flat or with recurved margins, 



mostly 1 to 2in. long. Capsule glabrous 1. B. viscosa. 



Sect. II. Ozyg'yne. — Anthers short, either adnate to a deeply 2-lobed connective, or par- 

 tially free with tlie connective more entire. Stigma deeply 3-lobed. Male flowers in a loose 

 raceme, — Tropical species. 



Leaves ovate or lanceolate, tapering at the b«,se, 1 to IJin. long 2. B. tristigma. 



1. B. viscosa (viscid), Miij. in Ann. Sc. Kat. ser. 3, i. 350, t. 15 ; Benth. 

 Fl. Austr. vi. 64. A tall shrub or tree, the flowering and fruiting branches 

 usually viscid. Leaves from oval-oblong to oblong-lanceolate or broadly linear, 

 mostly obtuse, tapering into a petiole, the margins often recurved, glabrous 

 above, pale or white-tomentose underneath, usually from 1 to above 2in. in 

 length. Flowers axillary or lateral, on recurved pedicels of J to nearly ^in., the 

 females solitary, the males often 2 or 3 together. Calyx-segments broad, 

 coloured, about 2 lines long. Petals small. Anthers (about ^ line long) twice 

 as long as broad, the cells wholly adnate to the entire connective. Female calyx 

 smaller than the male, the thickened pedicel appearing to form part of it, the 

 segments narrow with frequently small glands alternating with them. Ovary 

 nearly globular, the large calyptriform sessile stigma closely appressed when 

 young, raised and flat or concave when fully out. Capsule ovoid-globular, about 

 4 lines long, hard and glutinous, 8-celled and 8-seeded. — Muell. Arg. in DC.

2. B. tristigma (stigma 8-lobed), F. v. M. Fragm. vi. 181; Benth. FL 

 Axistr. vi. 68. A small viscid shrub, glabrous except the underside of the leaves. 

 Leaves resembling those of the common Olive, oval-elhptieal or oblong-lanceo- 

 late, tapering into a short petiole, the margins recurved or revolute, 1 to Ifin. 

 long. Flowers monoecious, the males very small, few in a loose raceme of about 

 lin. at the end of the branches, the pedicels 2 to 4 lines long. Calyx-segments 

 5, not h line long. Petals 3 times as long, ovate, obtuse, fringed inside at the 

 base with a tuft of hairs. Stamens very numerous on a hirsute convex or hemi- 

 spherical receptacle ; anther-cells short, quite distinct. Female flowers on a 

 pedicel of \\n. or longer when in fruit, either solitary at the end of the branches 

 or 1 or 2 at the base of the male raceme, smaller than the males at the time of 

 flowering, but the calyx-segments enlarging under the fruit to nearly 1 line.
