5. G. indicum (of India), Linn.; DC. Prod. vi. 281 ; Benth. Fl. AiuHtr. iii. 

 655. A decumbent ascending or erect annual, rarely exceeding 6in., covered 

 with a loose cottony -wool, sometimes very abundant. Leaves petiolate, spathu- 

 late or linear. Flower-heads small, densely clustered in ovate or oblong 

 terminal leafy spikes, with a few in the upper axils. Involucres ovoid, about 

 1 line long, the braois densely imbedded in wool, the tips only usually protruding. 

 Female florets very -numerous, with 2 or 3 hermaphrodite ones in the centre. 

 Pappus-bristles numerous, cohering in a ring at the base. — O. niliacwm. Eaddi : 

 DC. I.e. 



Hab.: Upper Eoper and Alligator Rivers, F. v. Mueller. 



The species is common in India, extending westward to the Nile and eastward to the Malayan 

 Peninsula and China. The Australian specimens are small, with very narrow leaves. 



6. Cr. indutum (clothed), Hook.f. in Hook. Loud. Journ. vi. 121, and in FL 

 Tasm. i. 217 t. 62 B.; Beiith. Fl, Austr. iii. 655. A little slender, erect, much- 

 branched annual, rarely above Sin. high and often not above lin., densely 

 cottony-white. Leaves linear, soft. Flower-heads small, sessile amongst leafy 

 bracts, at first dense but not in globular heads, and at length looser, forming 

 leafy corymbs. Involucre ovoid, about 1 line long or scarcely more, woolly at 

 the base ; the bracts oblong, with erect, scarious, brown or straw-coloured tips. 

 Female florets very numerous, with 2 to 4 hermaphrodite ones in the centre. 

 Pappus-bristles quite free. — G. .sericeum, Turcz. in Bull. Mosc. 1851, ii. 83. 



Hab.: Southern localities. 



30. LEPTORHYNCHUS, Less. 

 (Referring to the slender beak of achene.) 

 (Ehytidanthe, Benth.) 

 Involucre broadly turbinate, campanulate or hemispherical, the bracts much 

 imbricate in several rows, the short outer ones and the tips or laminse of the 

 others very thinly scarious and not spreading. Receptacle flat, without scales. 

 Florets all tubular, a few in the circumference usually female, more slender but 

 not longer than the others, 3 or 4-toothed ; disk-florets hermaphrodite, 5-toothed, 

 Anthers with fine tails. Style-brp,nches nearly terete, truncate. Achenes small 

 or narrow, somewhat compressed, glabrous or papillose, contracted at the top or 

 produced into a short beak. Pappus of several capillary bristles, scabroiis, 

 shortly barbellate or almost plumose towards the end. — Annual or perennial 

 herbs or undershrubs, more or less cottony or glandular-pubescent. Leaves 

 alternate, entire. Flower-heads pedunculate, the outer scarious involucral bracts 

 often descending along the peduncle. Florets almost always longer than the 

 involucre. 



The genus is limited to Australia. It is scarcely distinct from Helichrysum, differing in the 

 involucral bracts with more thinly scarious tips, neither spreading nor petal-like nor opaque, 

 and in the contraction of the achene at the top, which can in some species be only seen at 

 maturity, and then not always very decided. From Waitzia, Leptorhynclms differs in the 

 involucre and usually in the shorter beak to the achene. The florets, as in Ixiolcena and 



PodoUiiis, are usually longer in proportion to the involucre than in Helichrysum or Helipterum. 



Benth. 



Aehenes contracted at the top, but not distinctly beaked. Perennials or 

 undershrubs. Pappus-bristles equally and minutely denticulate. Outer 

 involucral bracts very thinly scarious, passing into the scarious scales of 



the peduncle 1. L. sqnamattii. 



Aehenes more distinctly though sometimes shortly beaked. Annual. In- 

 volucral bracts narrow, acute, small, very numerous, all ciliate with long . 

 hairs. 



Flower-heads 2 to 3 lines long , 2. i. pulchelltn. 



Flower-heads Jin. broad. Pappus-bristles plumose above the centre . . . 3. L. Baileyi.
