218 ELORA OF TASMANIA. [Composite. 
integerrimis utrinque lanatis, pedunculis solitariis terminalibus monocephalis, involucri squamis anguste 
linearibus acuminatis post anthesin reflexis extus lanatis, receptaculo piano papilloso, floribus radii 3-4- 
serialibus foemineis angustissimis 4-dentatis, disci latioribus 5-dentatis hermaphroditism antheris bicaudatis 
caudibus fimbriatis, achemis oblongis sericeis. (Gunn, 322.) (Tab. LXII. C.) 
Hab. Summit of Mount Olympus, Gunn. — (Fl. Jan.) 
A remarkable little plant, quite unlike its Tasmanian congeners in habit, and more resembling some of the 
Arctic and Alpine European tufted species of the genus. It has the habit of, and is similar in foliage to, Raoulia 
Tasmanica, but is smaller, and has a brown or buff-coloured, woolly tomentum on the foliage and scape. The 
capitula too are not sessile, but peduncled, the involucral scales are very different, and the receptacle is broad and 
almost plane. — Stems tufted, short, much branched, creeping and ascending, densely leafy, 1-2 inches long. Leaves 
about i inch long, spathidate, obtuse, spreading, equally woolly on both surfaces. Peduncle very short or \ inch 
long, slender, erect, densely woolly. Beads about \ inch long. Involucral scales very numerous, in about three 
rows, scarions or almost membranous, very narrow-linear; the outer tomentose externally. Jchemum oblong, 
pubescent, silky upwards, terete. Pappus hairs few, slender, scabrid. (Named after my friend M. Planchon, who 
has also examined this plant, and who agrees with me in considering that, under the present limitations of the 
genera of Gnaphalioid Composite, this must be ranked under Gnaphalium itself, though, as before remarked, it 
differs widely from its congeners.) — Plate LXII. C. Fig. 1, involucre ; 2, flower of circumference ; 3, of centre ; — 
all magnified. 
Gen. XXIX. ERECHTITES, Raff. 
CapiUdum niultiflorum, heterogamum, discoideum ; floribus marginalibus fcemincis multi- v. pauci- 
seriatis, tenuissimis, 2-4-dentatis ; disci hermaphroditism 4-5-dentatis. Receptaculum nudum, subpapil- 
losum. Involucrum cylindraceum ; squamis anguste linearibus, 1-seriatis. Styli rami truncati v. cono 
superati. Ackeuia oblonga, striata, obtusa v. apice attenuata, pilosa v. scabrida. Pappus pluriserialis, 
tenuissimus, scaberulus. — Herbse erectce, simplices v. ramosa, glalerrinue v. lanalce. 
This genus, as defined by De Candolle, chiefly differs from Senecio in the extremely slender, tubular, female 
florets of the ray. The majority of the species are Australian and New Zealand, the rest are tropical American. 
About a dozen Australian species are known, several of which are common to both sides of the Continent, and four 
of them to New Zealand also.— Tall, smooth or woolly, simple or branched, herbaceous plants, bearing corymbs of 
many exceedingly narrow heads, which have no ligulate flowers. Involucre cylindrical ; scales very long, narrow, 
erect, in one series, with a few short ones at the base. Receptacle narrow, papillose. Flowers of the circumference 
in one or many series, extremely slender, female ; those of the disc broader, hermaphrodite. Arms of the styles 
tipped with short, hairy cones. Achenia oblong, striated, hairy or smooth. Pappus of numerous, very slender, 
rough hairs, in many series.— The species of Erechtites abound in Australia and Tasmania ; a few are found in 
South America, and as far north as the Southern United States. (Name applied by Dioscorides to some species of 
Senecio.)
