1. P. aspalatha (DC. 1. c. 356); “glabrescent ; leaves scattered, 
sessile, elliptical or oblong, nerveless, rather fleshy, acute, the lower 
with 1-2 marginal teeth ; heads shortly pedunculate, terminal, many 
fl. ; inv.-scales linear-lanceolate, acuminate, as well as the twigs and

Has. Betw. Karroe R. and Dwaal, Burchell, 1427. Nieuweveld, Drege? (fide DC.) 
A scrap without flowers from Drege, in Herb. Sond, said to belong to this species, 
seems referable to Pegolettia polygalefolia. We therefore give the present species 
wholly on De Candolle’s authority. 
2. P. glaucescens (DC. 1. c. 357); the young parts downy, other- 
wise glabrous; leaves alternate, close, linear-spathulate, glaucous, some- 
what fleshy, nerveless, quite entire, obtuse; heads ending leafy branches, 
subsessile, 10-12 fl. ; inv.-scales linear, obtuse, loosely imbricated ; 
achenes silky ; pappus tawny. 
Has. Nieuweveld, Drege / (Herb. Hk., D., Sd.) 
A scrubby, rigid, robust, small shrub ; the old twigs hardening and spinescent, 
divaricate. Leaves 2-3 lines long, 1 line wide, narrowed to the base. Heads small. 
Tnvol. loosely 3-seriate ; the scales dry but not membranous. Our specimens are 
far from perfect. 
3. P. baccharoides (Less.! Syn. oo ; glabrous; leaves alternate, 
crowded, spreading, linear-trigonous, keeled, when dry furrowed beneath, 
acute or subacute ; heads sessile or subsessile, 3-12-flowered, either 
corymbose or solitary ; inv.-scales varying from narrow-oblong to ovate,
