Stoebe. ] COMPOSIT& (Harv.) 279 
XCII. STOEBE, Linn. 
Heads one-flowered. Jnv. scales oblong, imbricate, dry-membranous, 
the outer ones short and often woolly. Cor. tubular, 5-toothed. Style- 
branches pencilled at the abrupt point. Pappus of 5 or many bristles 
naked below, plumose above, slightly connected at base into a ring and 
falling off together; a small rim or annulus, in many species, exterior 
to the true pappus, and persistent on the oblong achene. Achene either 
glabrous or woolly, sessile, beakless. Stoebe and Seriphium, DC. Prodr. 
Pp. 259, 261. 
Small, rigid shrubs or half shrubs, almost all S. African. Leaves crowded, narrow, 
often pungent, very entire, linear, oblong or subulate, often spirally twisted, woolly 
and concave within, glossy, becoming glabrate externally. Heads crowded together 
in dense tufts (glomerules) or dispersed in long spikes, Name from oroiBn a crowd- 
ing or surrounding : alluding to the crowded leaves of many. I unite the genera 
Stoebe and Seriphium of most authors, because the species grouped under them agree 
in habit, foliage and floral characters; and merely differ by an obscure and variable 
character of the fruit; the achene in Stoebe possessing an annulus exterior to the 
pappus ; that of Seriphiwm being perfectly round-topped. I find an annulus in some 
species said not to possess one; and the breadth of margin varies very much, from 
species to species. .
