of the disc linear, empty. Pappus caducous, of few setz, either shortly- 
feathery or barbato-serrate ; ray-fl. either wholly without pappus, or 
with 1-2 bristles. DC. l. c. p. 300. 
South African suffrutices or half-herbaceous plants, with slender, rod-like, leafy 
branches. Leaves alternate, linear or subulate, acute, entire, smooth or ciliate at 
the margins. Heads pedunculate, solitary, small ; the ray blue, the disc yellow. 
Invol. scales mostly marked with long, glandular ribs. Nearly related to Mairea, 
from which it scarcely differs except by the scanty and less plumose pappus; I find 
the ray-flowers with or without pappus in species which are otherwise very closely 
allied. Name from yuuvos, naked, and oreos, a crown; alluding to the want of 
pappus in the ray-flowers. 
Inyol. scales glabrous or nearly so, flat, marked with 3 glandular rib-strie. 
Lys. with minutely revolute margins, one-nerved : 
Very slender; pedunc. glabrous; invol. scales few (1) gracile. 
Robust; pedune. villous; invol. scales many ... (2) fruticosum. 
Lys. channelled and keeled ; pedun. glandularly scabrous (3) angustifolium. 
Invol. scales hispid or pubescent, keeled : 
Pedune. elongate, one-headed; without bracts : 
Stems and leaves roughly hispid and scabrous ... (4) hirsutum, 
Stems glabrous; leaves glabrous, but ciliate ... (5) ciliare. 
Pedune. short, corymbose, pluri-bracteate ; leaves ciliato-

1. G. gracile (Less ! Syn. 186) ; quite glabrous, very slender, diffuse ; 
branches flexuous, laxly leafy ; leaves scattered, narrow-linear, acute, 
with revolute margins, one-nerved and veiny ; heads shortly peduncled, 
small; invol. triseriate, scales few, linear-oblong, flat, glabrous, ciliolate, 
with 3 glandular ribs. DC. l. ¢. p. 300. 
Has. Tradouw, Mundt and Maire! (Herb. Sond.) 
A very slender, scarcely lignesent plant. Branches filiform. Leaves about 1 in. 
long, § line wide, thin. Pappus of disc of one or two caducous, plumose bristles ; 
of the ray none. Ripe achenes not seen. 
2. G. fruticosum (DC.! 1. c. 300); nearly glabrous, shrubby ; 
branches rather closely leafy, glabrous ; leaves alternate, linear, acute, 
with revolute margins, one-nerved, glandularly-dotted, quite glabrous ; 
pedune., short, villous, with many barbato-ciliate bracts; invol. pluri- 
seriate, scales numerous, oblongo-lanceolate, acute, glabrous, ciliate, 
with 3 glandular ribs. 
Has. Near Swellendam, Drege! (Herb. Sond., Hook.) 
Much more robust than G. gracile, with larger fl. heads and involucres. Leaves 
1 inch long, 1-14 lines wide. Our specimens are very imperfect, and I have seen 
neither pappus nor achenes. 
8. G. angustifolium (Harv.); erect, nearly glabrous ; branches rod- 
like, glabrous, rather laxly leafy ; leaves subulato-filiform, channelled 
and keeled, acute, glabrous, very entire or the uppermost ciliate ; pe- 
dune. glanduloso-muricate; invol. triseriate, scales several, oblougo- 
lanceolate, acute, minutely glandular and ciliate, with 3 glandular ribs. 
Has. Near the River Zonder Einde, Zeyh.! 2743. (Herb., Sd., Hk., Cap.) 
1-14 f. high, woody below, corymbosely branched upwards. Branches erecto- 
patent. Leaves an inch or rather more long, not 4 line wide, the younger ones 
rigidly ciliolate, especially near their base, the older quite smooth-edged, all semi- 
amplexicaul. Pappus of disc of 2-3 caducous, barbellate bristles, of ray none. Ripe 
achenes glandularly-granulate on the disc. This has quite theaspect of Aster simulans.
