acuminate, the points cohering by their minutely hairy tips. Stigmatic cone 
rather long, but shorter than the filiform style. Nuts small, scabrous with short 
hairs. — DC. Prod. ix. 547.

10. H. filaginoides (Filago-like), Bentk. FI. Amtr. iv. 398. A dwarf 
erect much-branched corymbose plant, apparently shrubby, clothed in every part 
with a white cottony-wool, the specimen seen complete with the root, but 
scarcely 4in. high. Leaves crowded and almost imbricate towards the end of 
each year’s shoot, oblong-lanceolate, obtuse, with recurved margins, not 2 lines 
long. Flowers small, in dense terminal cymes almost contracted into heads, 
sessile within the imbricate bracts, which are as long as the calyx. Calyx- 
segments oblong-lanceolate, obtuse, rather above 1 line long. Corolla not 
2 lines long, the lobes about as long as the tube, with a ring of hairs in the 
throat. Anthers acuminate with long exserted points, connected by the minute 
hairs of their tips. Style very short ; the stigmatic ring broad and cup-shaped, 
with a small central cone. Fruit not seen. 
Hab.: Towards Cooper's Creek, HowitVs Expedition. 
11. £1. ventricosum (corolla-tube swollen), H. Hr. Prod. 494 ; Benth. FI 
Amtr. iv. 399. An erect corymbosely- branched annual of A to 1ft., becoming 
diffuse when old, hirsute with rigid strigose or spreading hairs. Leaves narrow- 
linear, acute, with revolute margins, rarely above ^in. long. Flowers in short 
compact spikes, interspersed with long leaf-like bracts, all as well as the calyxes 
very hispid. Calyx-segments narrow, shorter than the corolla-tube. Corolla- 
tube about 2 lines long, slender to above the middle, ventricose below the throat, 
which is pubescent inside. Anthers small, acuminate, the points connected by 
the minutely hairy tips. Style long and filiform, with a short stigmatic cone. 
Fruit tipped by the persistent base of the style, the nuts small, minutely strigose 
or nearly glabrous. — DC. Prod. ix. 547. 
Hab.: Gulf of Carpentaria, R. Brown : Port Denison, Fitzalan ; several other localities in the 
tropics. 
12. H. tenuifolium (thill leaves), It. Br. Prod. 494 ; Benth. FI. Amtr. 
iv. 399. Stems erect, branching, hard or almost woody at the base, 1ft. high or 
more, more or less hoary as well as the foliage with short appressed hairs. 
Leaves linear, acute or almost obtuse, with revolute margins, f to lAin. long. 
Flowers distant, forming interrupted once or twice-forked spikes, interspersed 
especially at the base with a few bracts, which are rarely entirely wanting. 
Calyx glabrous or strigose, the segments very acute, about 2 lines long, the 
2 outer ones often larger than the others. Corolla-tube about as long as the 
calvx. ventricose above the middle, shortly bearded in the contracted throat, 
the limb nearly as long as the tube. Anthers acuminate, the points cohering by 
their minutely hairy tips. Style slender, the stigma broadly 4-lobed with a 
small central cone. Fruit tipped by the persistent base of the style, the nuts 
slightly scabrous-pubescent. Embryo usually curved. — DC. Prod. ix. 547.

13. H. paniculatum (flowers in panicles), It. Iir. Prod. 494 ; Benth. FI. 
Amtr. iv. 399, nut of Iloxb. Erect and paniculately branched with the habit of 
II. tenuifolium, but much more slender, more or less hirsute or nearly glabrous. 
Leaves linear-filiform, with revolute margins. Panicles at length very divaricate, 
with dichotomous filiform branches. Flowers very much smaller than in II. 
tm a I folium , but otherwise similar. Calyx 1 line long, strigose, with acutely 
acuminate segments. Corolla-tube rather longer than the calyx, ventricose
