Small, glabrous, alpine, tufted herbs. Leaves lax or imbricate, long or 
short.-— Heads subsessile, small, inconspicuous, 4-15-flowered ; outer fl. 
female; inner male or hermaphrodite. Involucre cylindric; scales few, erect, 
in 1 or 2 series, coriaceous. Eeceptacle narrow, flat, papillose. Female fl. : 
pappus 0 or very small ; corolla tubular, unequally 3-5-cleft at the mouth, 
inflated ; style bifid, inserted on a spherical disk ; aeheue 3- or 4-angled, or 
costate, obovoid or obconic. Hermaphrodite fl. : corolla narrow campanulate, 
4-cleft ; stamens almost free ; style truncate. 
A small genus, of which the species included under Ceratella and Trineuron (genera 
founded by myself on Auckland Island plants) differ much in lax habit and foliage from the 
original Fuegian Abrotanella emarginata , which has closely imbricate, minute leaves ; my 
Tasmanian genus Scleroleima, again, has the habit of the Fuegian one. I follow A. Gray 
(Proceedings Amer. Acad.) in reducing all to Abrotanella. The section Trineuron is found 
on the Australian alps and New Zealand ; and one species is Fuegian.
