5. S> multicaulis (many-stemmed), Benth. Fl. Austr. iii. 440. Annaal or 

 with a perennial almost woody base and erect rigid stems, glabrous and smooth 

 or minutely scabrous-pubescent. Leaves sessile, linear, with revolute margins. 

 Stipular sheath very short. Flowers in small but dense terminal or at length 

 lateral clusters or heads. Calyx-lobes thick, obtuse, incurved, as long as the 

 tube and nearly as long as the corolla. Corolla not above 1 line long, usually 

 pubescent outside, the tube slightly hairy inside ; lobes longer than the tube, 

 thickened towards the end. Stamens inserted at the orifice of the tube ; anthers 

 oblong, not OKceeding the lobes. Carpels opening nearly to the base.

6. S. Jacobsoni (after Geo. Jacobson), Bail. Bot. Bull. iii. A glandular- 

 hispid annual of 12 to 15in. high. Stems few, erect. Leaves linear-lanceolate, 

 usually under 2in. long, somewhat coriaceous, veins very obscure, upper surface 

 and midrib on the under side covered by light hair-like scales, margins revolute, 

 the two last leaves close under the heads of flowers. Stipular sheath somewhat 

 prominent, bordered by rather long bristles. Flowers small, very numerous, in 

 dense terminal heads, often exceeding -Jin. diameter, the flowers intermixed with 

 long scarious white cilia. Calyx-lobes narrow-linear, hirsute on the back, about 

 If line long, tube slender, of equal length with the lobes. Corolla scarcely 

 exceeding the calyx-lobes, scaly-hairy outside, glabrous on the inner surface, the 

 tube very hairy inside. Stamens inserted at the orifice of the tube and alternat- 

 ing with the lobes of corolla, about as long as the lobes. Anthers large, oblong. 

 No mature carpels on the specimens received,

7. S. exserta (stamens exserted), Benth. Fl. Austr. iii. 441. Apparently 

 annual, erect, more or less hirsute. Leaves long-linear or linear-lanceolate. 

 Stipular bristles rather long and fine. Flowers in dense globular terminal or 

 sometimes lateral heads. Calyx-lobes lanceolate, ciliate, much longer than the 

 tube, and often nearly as long as the corolla, the tube hirsute with almost scale- 

 like bristles. Corolla nearly 3 lines long, the tube short and broad, the lobes 

 much longer, lanceolate. Stamens inserted at the orifice of the tube, as long as 

 or much longer than the lobes. Fruit -only seen young. 



Hab.: Islands of the Gulf of Carpentaria, R. Brown. 



8. S« membranacea (leaves membranous), R. Br. Herb.; Benth. Fl. Austr. 

 iii. 441. A slender annual, sprinkled with minute hairs or nearly glabrous. 

 Leaves on rather long petioles, ovate or elliptical, | to IJin. long, thin and 

 membranous. Stipular sheath very short, with very fine often long bristles. 

 Flowers very small, in small terminal heads. Calyx-lobes lanceolate, shorter than 

 the corolla. Corolla white, scarcely above 1 line long, the lobes longer than the 

 tube. Stamens inserted at the orifice of the tube, exceeding the lobes. Fruit 

 not seen.

9. S. debilis (feeble), Benth. Fl. Austr. iii. 441. Slender and diffuse, 

 probably annual, glabrous or minutely scabrous. Leaves petiolate, ovate or 

 oblong-lanceolate, obtuse or scarcely acute, not rigid, under fin. and mostly under 

 fin. long. Flowers numerous, in dense heads mostly terminal. Calyx-lobes 

 lanceolate-subulate, longer than the tube. Corolla nearly 2 lines long ; tube 

 cylindrical, slightly hairy inside but not at the orifice ; lobes pubescent outside, 

 very much shorter than the tube. Stamens inserted at the orifice of the tube and 

 shorter than the lobes. Fruit small, the carpels opening to the base.
