5. G. Wrightii (Harv.) ; leaves petioled, cordate, repando-denticulate 
with subrevolute margins, soon glabrous above, thinly albo-tomentose 
beneath; petioles, scapes and iny. sc. thinly cobwebbed, becoming 
nearly glabrous, the scapes scale-bearing ; inv. sc. in 4-5 rows, lanceo- 
late, acute ; pappus rufous. 
Has. Near Simonstown, C. Wright, 343. (Herb. D.)

In the shape of the leaves this agrees with @. tomentosa, but the scanty tomentum we 
is white, not rufous, and the involucre is nearly glabrous. Heads of large size, with ) 
35-40 rays. 
6. G. leucothrix (Harv.); leaves oblong, cordate at base, deeply 
inciso-sinuous, and subdentate, with revolute margins, glabrous above, 
persistently rufo-tomentose beneath ; scapes squamellose, cobwebby or 
nude below, tomentellose at the summit; inv. sc. 4-5 seriate, minutely 
tomentose or glabrate; pappus white. °

This may possibly be a natural hybrid between @. ferruginea of which it has the 
foliage and pubescence, and G. Burmanni which it resembles in involucre and pap- 
pus. I have seen but a solitary specimen. 
7. G. Burmanni (Cass. Dict. 18, p. 461); leaves petioled, elliptical, / 
oblong, or obovate, more or less cuneate or tapering at base, either | ' 
minutely denticulate, toothed, or sinuous-toothed (very variable in this 
respect), glabrous above, either glabrous or thinly canous beneath ; 
scapes scale-bearing, glabrous or cobwebbed, or minutely velvetty; inv. 
se. about 3-seriate, lanceolate, subglabrous ; pappus slender, snow-white, 
eq. the dise. Less. in Linn. 1830, p. 294.

Has. Both varieties near Capetown and in the Western Districts generally. 
(Herb. Th., D., Hk., Sd.) 
I cannot find either in pubescence or the toothing of the leaves any permanent 
character between the above varieties, which grow in the same districts and often 
intermixed. The pappus is constantly and conspicuously white, by which character 
those with sinuous leaves are known from subsimilar forms of @. ferruginea.

8. G. cordata (Less. in Linn. v. p. 297); leaves long-petioled, mem- 
branous, elliptical or oblong-ovate, cordate at base, entire or denticulate, 
sparsely pilose becoming nude above, softly and persistently albo- 
tomentose beneath, and when young also clothed with long, brown, 
silky, deciduous hairs ; inv. se. at length reflexed ; ripe-achenes long- 
beaked. DC./ 1. c. 16. Arnica cordata, Th.! Cap. 628.

Petioles 3-5 in. long; lamina 24-5 in. long, 2-3 in. wide, obtuse or acute. Scape 
12-15 in. long, tomentose. Inv. very woolly. Rays yellow, not much longer than 
the inv. scales.
