membranous, the outer short and often woolly. Corolla tubu-

Characters of Stabe, except : Pappus 0!— #7. Cap. iii. p. 285. 
P. tortilis, Cass., found on the Cape flats, is so like Stabe perotrichoides 
in aspect, that it may easily be mistaken for it ; it is always distinguishable 
by the want of pappus.

Heads several-flowered, moncecious, all the flowers tubular ; 
female marginal, 1-6, among the innermost involucral scales 
or palee; male numerous, central, 5-toothed. Involueral

nude in the centre. Pappus 0 in the female flowers ; in the 
male 1-seriate, of slender bristles, plumose in the upper part.
