778 LXIV. EUBIACE^. [.■SpennacoCf. 



1. S. brachystema (short stamens), R. Br. Herh.; Benth. Fl. Austr. iii. 

 439. An erect or spreading rather rigid annual, attaining 1 or 2ft. and not 

 much branched, or sometimes much smaller, more or less pubescent or 

 hirsute, or sometimes nearly glabrous. Leaves sessile, linear lanceolate or 

 rarely oblong, mostly 1 to l^-in. long, occasionally clustered in the axils. 

 Bristles of the stipules rather long. Flowers small, in dense terminal or lateral 

 heads or clusters. Calyx-lobes 4, acute, often unequal, the longer ones as long 

 as the tube. Corolla about 1 line long, bearded inside at the orifice of the tube, 

 the lobes very short. Anthers small, ovoid, on very short filaments at the base 

 of the tube. Capsule about 1| line long, more or less of the dissepiment remain- 

 ing attached to one of the carpels after dehiscence. — S. stricta, F. v. M. Fragm. 

 iv. 41, not of Linn. 



Hab.: B. coast, R. Brown; Port Denison, Fitzalan ; Burnett Kiver and Brisbane Biver. 

 Moreton Bay, i?. v. Mueller; Rookhampton, Thozet, Dallachy (the latter with rather broader 

 leaves and more hirsute) . 



2. S. pogOStoma (bearded at mouth), Benth. Fl. Austr. iii. 440. Annual, 

 erect and quite glabrous. Leaves linear or linear-lanceolate. Stipular bristles 

 rather long. Flowers small, not very numerous, in terminal and lateral heads. 

 Calyx-lobes lanceolate, very acute, almost pungent, longer than the tube, and 

 almost as long as the corolla. Corolla little more than 1 line long, deeply 

 coloured when dry, very densely bearded inside at the orifice of the tube ; lobes 

 longer than the tube, inflected at the tips. Anthers small, ovate, almost sessile 

 at the base of the tube as in S. brachystema. ' 



Hab.: Cape York Peninsula. 



Var. Ivispida, Bail. Bot. Bull. iv. Plant clothed with short somewhat stiff white hairs. Stems 

 procumbent, with erect branches from 6 to 12in. high. Leaves linear to linear-lanceolate, J to 

 IJin. long, the short almost pungent point often recurved, margins revolute. Stipular sheath 

 and bristles of medium length. Calyx-lobes lanceolate with bristle-like points. Corolla 

 pubescent, about 2 lines long, white, not becoming much discoloured in drying, the tube and 

 lobes of about equal length, densely bearded at the orifice of the tube, the lobes with infiexed 

 tips. Anthers small, ovate, sessile at the base of the tube. No ripe capsules on the specimens 

 examined. Hab.: Musgrave Telegraph Station, Cape York Peninsula, Geo. Jacohson. 



3. S> uniseta (stipules often reduced to a single bristle). Bail. Bot. Bull. iii. 

 An erect slightly branched hispid annual, under 1ft. high. Stems slender, not 

 so hispid as the leaves. Leaves narrow-linear, less than an inch long, with 

 revolute margins. Stipules reduced to a single-branched bristle, closely ap^ressed 

 to the stem and rather long, but often concealed by the scale-like hairs of the 

 leaves. Flowers small, in dense terminal heads. Calyx-lobes acute, often 

 unequal, longer than the tube, bristly. Corolla-lobes ovate, patent, nearly 

 glabrous, under 1 line long ; tube about as long as the lobes, bearded inside 

 except at the base. Stamens inserted about the middle of the corolla-tube ; 

 filaments very slender. Anthers very small. No mature carpels on the specimens 

 examined. 



Hab.: Musgrave Telegraph Station, Cape York Peninsula, Geo. Jacohson. 



4. S. marginata (leaf margined), Benth. Fl. Austr. iii. 440. Prostrate, 

 rigid, scabrous and smooth, or the angles of the stem and margins of the leaves 

 scabrous. Leaves sessile, ovate to broadly lanceolate, -J- to IJin. long, mucronate- 

 acute, rigid, undulate, with thickened callous margins. Stipular sheath very 

 short, with rigid bristles. Flowers numerous, in dense terminal or lateral heads. 

 Calyx-lobes lanceolate, rigidly acuminate, longer than the tube, and usually 

 exceeding the corolla. Corolla about 1 line long, the tube very broad , glabrous 

 inside ; lobes longer than the tube, inflexed and thickened at the end, bearded 

 inside at the base. Stamens inserted about halfway up the tube and included in 

 it. Carpels opening inside to the base.
