57. B, cymosa, IJudL in Hueg. Enum. 16. A glabrous, often glaucous 

 undershrub or slirub, forming? a thick stock with erect virgate branches. 

 Leaves sessile, linear-terete, often crowded towards the upper part of the 

 branches or clustered in the axils, J to 1 in. or rather longer, sometimes fewer 

 and more distant, the larger cues rarely flattened with revolate margins but 

 always narrow-linear and quite entire. Flowers rather small, usually nume- 

 rous and cymose, on long terminal peduncles. Pedicels short. Sepals short 

 and broad ."^ Petals attaining about 3 lines. Filaments ciliate, slightly dilated 

 at the base, terete and glandular upwards ; anthers minutely apiculate.

3. ACRADENIA, Kipp. 



Calyx 5-cleft, rarely 6- or 7-cleft. Petals 5, rarely 6 or 7, imbricate. 

 Disk thick, entire. Stamens 10, rarely 12 or 14, inserted outside the disk; 

 anthers all similar and perfect. Cai-pels usually 5, united almost to the top, 

 each terminating in a glabrous gland. Styles termigal, united in one tiliform 

 style, ^Yith a small stigma. Ovules 2 in each carpel, collateral or almost 

 superposed. Cocci 5 or fewer, 2-valved ; endocarp and seeds unknown. 

 Leaves opposite, 3-foliolate. Flowers white, in a terminal trichotomous 

 cyme. 



The genus is limited to a single species, endemic lu Tasmania. It is evidently nearly allied 

 to Boroiiiu and especially to Ziena, from which it differs in the flowers, usually 5-nieroUB, with 

 all the stamens perfect aud no glands to the disk. The endocarp has been described, on the au- 

 thority of Kippist, as not separating, but the only fruits knowu are open and have already shed 

 their seed ; and, on comparing them carefully with those of Q{\itv Dioswea in a similar state, 

 I cannot but conclude that, as is usual in the tribe, the eudocarp has been cast with the seed. 



^ Kipp. in Tram, Linn. Soc, xxi. 207, i. 22. A shrub 

 of 8 to 12 ft., glabrous or the young shoots minutely pubescent. Leaves 

 mostly opposite, 3-foliolate, with a short common petiole; leaflets oblong- 

 lanceolate, oUtuse, 1 to 2 in. long, more or less crenatcly toothed, coriaceous, 

 green on both sides, usually scabrous, with prominent glands. Cymes nearly 

 sessile at the ends of the branches, loosely trichotomous. Sepals distinct, 

 short. Petals 2-^ to 3 lines long, pubescent outside. Filaments filiform, 

 glabrous, scarcely shorter than the petals; anthers not apiculate. Ovary 

 very vdlous, except the small glands terminating each carpel. Cocci hard, 

 tnnicate, scarcely beaked, transversely wrinkled.— Hook. f. Fl. Tasm. i. 69.

4. CROWEA, Sm. 



Calyx 5'clcft. Petals 5, imbricate in the bud. Disk annular. Stamens 

 10, shorter than the petals ; filaments flattened, ciliate or woolly ; anthers 

 linear, hirsute, tipped with long hirsute appendages. Ovary 5-lobed; styles
