4. H. IVEillari (after T. Barclay Millar), Bail. 2nd Suppl. 8yn. Ql. Fl. 5. 

 Branches slender, reddish-brown, silky-hoary or more or less clothed with white 

 silky hairs. Leaves linear, acute, and apiculate, 2 to Sin. long, 1 to 1 J line broad, 

 margins revolute, the upper surface glabrous, hoary-white on the under side, the 

 midrib prominent but not rusty as in H. angiistifolia. Spikes fin. long, terminal 

 or in the upper axils bearing 1 or 2 flowers. Sepals ovate, about 4 to 5 lines 

 long, silky-hairy outside. Petals cuneate, about 6 or 7 lines long, the end deeply 

 emarginate. Stamens about 20, with a few filiform staminodia outside. Anthers 

 oblong, longer than the filaments. Carpels 2, villous. 



This species is very closely allied to Hemistemma angustifolia, R. Br., but of a more robust 

 habit, with fewer and larger flowers in the spike, and wanting the prominent rusty-red midrib of 

 the leaf of that species. — Bail.

5. H. synandra (anthers close together), F. v. M. Fragm. iv. 151. An erect 

 branching shrub. Leaves subcoriaceous, lanceolate or broad-linear, 4 to 6 lines 

 long, 1 to 1|^ line broad, margins revolute, deep glossy-green above, slightly 

 canescent underneath. Flowers solitary, subsessile. Sepals 2 to 4 lines long, 

 sparsely puberulous, outer ones oblong-lanceolate, inner ones broad or orbicular. 

 Petals obcordate-ovatei about 5 lines long. Stamens about 20, unilaterals, fila- 

 ments about 1 line long, cohering at the base, anthers linear, no staminodia. 

 Carpels slightly silky, oblique ovate, ovules often 3. Seeds glossy-brown. 

 Arillus white, thin. '

6. H. Stricta (erect), R. Br. Herb. ; F. Muell. PI. Vict. i. 15 ; Benth. Fl. 

 Aicstr. i. 2. Erect, spreading, or diffuse, but scarcely prostrate, sometimes throw- 

 ing up almost simple stems of 6in. from a thick rhizome, sometimes attaining 

 several feet in height, more or less hoary or scabrous, with a minute stellate tomen- 

 tum, although sometimes appearing glabrous at first sight. Leaves narrow-linear, 

 erect or spreading, rather obtuse, mostly J to ^in. long, the closely revolute margins 

 disclosing little more than the midrib underneath. Flowers nearly sessile, or on 

 pedicels of 2 or 3 lines in length. Sepals usually about 8 lines long, oblong, 

 lanceolate, or the inner ones ovate. Stamens usually 8 to 12. Carpels tomen- 

 tose, or very rarely glabrous, with 4 to 6, or very rarely more ovules in each. 

 Arillus usually very small. — Pleurandra stricta, R. Br. in DC. Syst. Veg. i. 422 ;

Hab. : Various parts of Southern Queensland. 



Var. canescens. Leaves and calyx more or less hoary with stellate hairs. Flowers pedunculate 

 or more rarely nearly sessile. Ovules usually 4. 



Var. hirtiflora. Leaves nearly as in the var. canescens. Calyx usually large, more sessile, 

 and hirsute with spreading hairs. Ovules usually 6 to 8 or more. 



7. H. Billardieri (after Dr. J. J. Labillardike), F. v. M. PL Vict. i. 14 ; 

 Benth. Fl. Austr. i. 28. Stems weak, sometimes short and erect, but more fre- 

 quently trailing to the length of 2 or 3 feet or more over other shrubs, the 

 branches clothed with stellate hairs, often mixed with long spreading ones. 

 Leaves from obovate, ovate or oval-oblong to oblong-euneate or narrow-oblong, 

 the larger ones ^ to lin. long, but in the commoner slender varieties not half that 

 size, the margins recurved, more or less stellately pubescent, especially under- 

 neath, and scabrous above, but becoming glabrous with age. Pedicels terminating 

 short, leafy shoots, or apparently axillary, slender, and recurved, J to ^in. long. 

 Sepals 2 to 3 lines long, or in some varieties rather shorter or longer, the outer
