Olearia.] LXV. COMPOSlTiE. SOo 



afterwards that this was not a constant character, aad his genus was suppressed, and the 

 eirourastanoe that this abnormal peculiarity occurs on some specimens of one species of Olearia, 

 can surely be no reason for now transferring the name founded on it to a large genus where it 

 has not been observed in any other species. 



In the subdivision of Olearia, I have adopted the main sections proposed by Archer (Journ. 

 Linn. Soo. v. 17, 20), founded on the indumentum, which, with the exception of two or three 

 species where it almost disappears, seems to be the most available in a genus where so many 

 species pass into each other by almost insensible gradations. — Benth. (mostly). 



Section I. Asterotriohe. — Iiidumentum of the wider side of the leaves consisting of 

 stellate hairs, sometimes very close and almost mealy. 



Leaves alternate, mostly toothed or sinuate. 



Leaves ovate-oblong or lanceolate, smooth or scabrous above. Flower- 

 heads rather small. Involucres broadly turbinate. Achenes hairy . . I, O. stellulata. 

 Leaves ovate-lanceolate, acute, rather thin and somewhat glutinous. 



Flower-heads in pedunculate corymbs 2. 0. Nernstii. 



Leaves alternate or opposite, narrow, quite entire. Leaves alternate, 

 narrow-linear ...... 3. 0. liygrophila. 



Section II. XSriotriche. —Indumentum of the -under side of the leaves consisting of densely 

 intricate woolly hairs. Leaves alternate, often small. 



Flower-heads (usually small and ovoid) axillary or on very short axillary 

 branehlets, forming long leafy racemes. Bay-florets conspicuously 

 exceeding the style. 

 Leaves 1 to 4 lines long, obovate to oblong-linear, the upper surface 



glabrous or scabrous 4. 0. ramiilosa. 



Leaves narrow-linear, 3 to 6 lines long. Flower-heads forming short, 



dense, terminal, leafy racemes 5. 0. subspicata. 



Flower-heads usually hemispherical, terminal, solitary or corymbose. Bays 

 conspicuous. 

 Leaves mostly reflexed, clustered, about 1 line long. Flower-heads 



solitary 6. 0. ramosisnma. 



Leaves oblong-cuneate, 3 to 4 lines long. Flower-heads solitary, on long 

 branehlets 7.0. pimeleoides. 



Sectio)j III. Adenotriche. — Plant glabrous, usually glutinous. Involucre ovoid, tur- 

 binate or rarely hemisplierical, the bracts usually obtuse, rigid, scarious on the margins and often 

 ciliate. 



Flower-heads very large. Involucre broadly turbinate, above Jin. long. 



Leaves narrow, cuneate 8. O. magniflora. 



Flower-heads small, numerous, in a, leafless corymbose panicle. Leaves 



elliptical-oblong or lanceolate, IJ to Sin. long 9. 0. elUpticd. 



Section IV. lUerismotriclie.— (fiaftj'ous, glandular-pubescent or hirsute, and often 

 glutinous, the hairs simple rigid, white or transparent and septate. Involucre hemispherical, triih 

 narrow, usually acute bracts. 



Flower-heads rather large; few, trimmed, or, in the upper axils, on peduncles 

 shorter than or rarely exceeding the leaves. Leaves obovate or oblong- 

 crenate, very viscid. Peduncles longer than the leaves. Involucre 

 scarcely Jin. diameter 10. 0. xerophila. . 



Flower-heads solitary, on peduncles very much longer than the leaves. 



Leaves mostly oblong, obtusCj coarsely toothed 11. O.rudis. 



1. Od Stellulata (hairs in stars), DC. Prod. v. 272 ; Benth. Fl. Austr. iii. 

 478. An erect shrub of 3 to 5ft. Leaves alternate, oblong or lanceolate, obtuse 

 or acute, more or less sinuate-toothed or rarely almost entire, glabrous scabrous 

 or stellate-hairy above, white or rusty underneath with a dense stellate tomentum, 

 varying in size from all under fin. in some specimens to above 2 or even 3in. in 

 others. Heads in the original form rather small; in leafy panicles. Involucre 

 turbinate. Ray-florets about 8 to 12 ; disk-florets rather more numerous. 

 Anthers scarcely auriculate. Style-appendages almost acute. Achenes more 

 or less hirsute. Pappus with a distinct external series of short bristles. — Aster
