§ 6. Hemihibbertia. — Carpels glabrous or rarely villous. Stamens very numerous, with 

 several small, subulate or elavate staminodia outside. Leaves flat. Flowers pedunculate. 

 Leaves distinctly petiolate, ovate, or oblong, mostly toothed. 



Carpels 3, glabrous, 6- to 8-ovulate IS. H. dentata. 



Leaves oblong-lanceolate, tapering at the base, and halt stem-clasping . 19. H. glaberrima. 

 Leaves narrow-elongate to linear-lanceolate, 6in. long, 2 to 6 lines 



broad 20. H. longifolia. 



Leaves narrow linear-lanceolate, 2 to Bin. long, 2 to 4 lines broad, 



staminodia numerous, carpels 4 21. J?, cenotheroides

few, carpels 3 22. i?. Bennettii. 



1. H. Banksii (after Sir J. Banks), Benth. Fl. Austr. i. 20. Young branches 

 and under side of the leaves densely clothed with a short, soft, rusty tomentum. 

 Leaves oblong, obtuse, 2 to Sin. long, ^ to near lin. broad, the margins more or 

 less recurved, narrowed into a short petiole, glabrous above and somewhat shining 

 when old, the pinnate and anastomosing veins prominent underneath. Spikes 

 terminal, 1-sided, rusty-villous, about lin. long, the flowers closely sessile. Sepals 

 about 4 lines long. Petals longer. Stamens about 20, obtuse, with half as many 

 staminodia outside, about one-third shorter. — Hemistemma Banksii, E. Br. in DC. 

 Syst. Veg. i. 414. 



Hab.: Endeavour Eiver, Banks. 



2. H. Brownei (after Robert Brown), Benth. Fl. Austr. i. 21 . Young branches 

 clothed with a short rusty down. Leaves oblong-lanceolate, obtuse or scarcely 

 pointed, 2 to Sin. long, closely sessile and very obtuse or rounded at the base, the 

 margins flat, glabrous, and at length almost shining above, white underneath, 

 with the midrib alone prominent and rust-coloured. Spikes terminal, 1 -sided, 

 silky-villous. Sepals scarcely 4 lines long, acute. Stamens nearly as in H. 

 Banksii. 



Hab. : Eecorded, for Queensland by F. v. M. 



3. H. candicans (whitish), Benth. Fl. Austr. i. 21. Like H. dealhata in the 

 white tomentum that covers the under side of the leaves, but it is rather more 

 silky or rusty on the peduncles and calyx, the leaves are rather narrower, and the 

 inflorescence is very different ; peduncles all axillary, | to lin. long, bearing at 

 their extremity 1 to S sessile flowers, and bracts and sepals usually broader. 

 Stamens and carpels the same as in H. Banksii. — Hemistemma candicans, Hook, 

 f. in Kew Journ. Bot. ix. 48, t. 2.
