28. STUARTINA, Sond. 



(After C. Stuart.) 



Involucre ovoid, the bracts imbricate, appressed without appendages or the 

 inner ones with recurved horn-like tips. Eeceptacle without scales. Florets 

 few, those of the circumference female filiform, those of the disk very few, 

 hermaphrodite, 4 or 5-toothed. Anthers with small fine tails. Style-branches 

 terete, truncate. Achenes obovoid-oblong. Pappus none. — Annual, with the 

 habit of Giiaphalium. 



The genus is limited to a single species, endemic in A ustralia, differing from Gnaphalium in 

 the absence of the pappus. 



1. S> IVIuelleri (after P. v. Mueller), Sond. in Linnma xxv. 522. A small 

 diffuse or slender annual, rarely 6in. high. Leaves on long petioles, nearly 

 orbicular, about Jin. diameter, woolly-tomentose or at length glabrous above. 

 Flower-heads very small, in little globular clusters, sessile amongst floral leaves 

 similar to those of the stem, the petioles much longer than the clusters. Invo- 

 lucres narrow, scarcely 1 line long, surrounded by a tuft of long woolly hairs, 

 the bracts appressed but after flowering 1 to 3 of the inner ones are usually 

 produced into recurved horns. Florets from 5 to 7, of which 1 or 2 in the centre 

 hermaphrodite. Achenes glabrous or papillose. 



Hab.: St. George, J. Wedd. 



29. GNAPHALIUM, Linn. 



(From the Greek gnaphalon, wool ; flower-heads woolly.) 



(Leontopodium, E. Br.; Euohiton, Cass.) 



Involucre ovoid or campanulate (rarely hemispherical?), the bracts imbricate 

 in several rows, more or less scarious, with or without small spreading tips. 

 Receptacle without scales. Florets of the circumference female, filiform, in 2 or 

 more rows, often very numerous, those of the disk fewer, often very few, her- 

 maphrodite, tubular, 5-to6thed. Anthers with fine tails. Style-branches in the 

 disk-florets nearly terete, truncate. Achenes oblong or obovate, not striate, 

 glabrous or papillose. Pappus of capillary bristles, in a single row. — ^Herbs, 

 annual or perennial, more or less cottony or woolly. Leaves alternate, entire, 

 usually soft. Flower-heads sinall, usually clustered, either in the upper axils 

 or in terminal spikes, corymbs or compound heads, rarely solitary. 

 A considerable genus, distributed over nearly the whole globe. 



Clusters or compact corymbs of flower-heads terminal, leafless, solitary or 



several in an irregular panicle 1. G. luteo album. 



Clusters forming a terminal globular head, usually surrounded by a few 

 floral leaves. 



Annual 2. G. japonicum. 



Perennial with a tufted or creeping rhizome. Floral leaves narrow, 



glabrous above 3. G. colUnum. 



Clusters of flower-heads axillary or forming a terminal spike. 



Flower-heads about 2 lines long 4. G. purpureum. 



Flower-heads about 1 line long 5. G. indicum. 



Flower-heads in little leafy corymbs. Branching annual of 1 to 3iu. . . . 6. G, indutuvi. 



1. G. luteo-album (yellowish-white), Linn.; DC. Prod. vi. 230; Benth. 

 Fl. Avstr. iii. 653. " Karkar," Mitchell River, Palmer. An annual or perhaps 

 biennial, densely woolly-white, with ascending or erect stems of 1 to. l|ft. when 

 full grown. Lower leaves petiolate, obovate or oblong-spathulate, obtuse; 

 upper ones sessile, linear or lanceolate, acute, all usually soft and retaining 

 the wool on both sides. Flower-heads in loose terminal nearly globose clusters 

 or dense corymbs, without floral leaves, either solitary and terminal or several
