wide. Rays “ white above, red beneath” (M.E.B.). I have examined Krauss’s 
original specimen in Hb. D. of ‘‘ G. Natalensis,” Sch. B,, and find it a “Zasiopus;” 
in other respects it agrees with the pilose forms of G@. viridifolia. I have not seen 
ripe achenes ; ovaries of the disc nearly glabrous; of the marg. fem. fl. hispidulous. 
14. G, aurantiaca (Sch. B. 1. c.) ; leaves membranous, lanceolate or 
oblongo-lanceolate, acute, tapering much at base into a short petiole, 
entire or denticulate, setose, becoming nude above, cobwebby-canescent, 
becoming nude and netted-veined beneath ; invol. sc. cobwebbed, sub- 
biseriate, acuminate; achenes hispid; pappus violet-purple. Wa/p.

woolly, 8-15 inches high, without bracts. Rays (when dry) rich red-brown above,

cuneate-attenuate at base, at first setose, afterwards glabrous above, 
persistently tomentose, strongly midribbed and penni-nerved beneath ;

ge Range of our two varieties look very distinct, but I possess an inter-
