articulation) with long erect silky hairs, }-3 in. long; lobes broadly ovate 
or ovate-orbicular, obtuse or rounded at the apex, silky-villous without, 
1-1} lin. long. Petals reduced to small teeth. Filaments short;

19. G. oliveriana, Engl. & Gilg in Engl. Jahrb. xix. 262. 
Flowering stems numerous, simple, erect, glabrous, 8-15 in. high, 
arising from a woody rootstock. Leaves crowded, linear or linear- 
lanceolate, acute, ending in a hard point, glabrous, 3—1 in. long, 1—2 lin. 
broad. Heads terminal, many-flowered (20-30) ; involucral bracts 6-8, 
ovate-oblong, green, sessile, rounded at the apex, with membranous or 
coloured margins, glabrous (“ rarely subciliate,” Gilg), 4-2.as long as the 
flowers. Flowers ‘‘orange” or ‘‘red,” 4-merous, pedicelled ; pedicel 
minute, crowned by a dense brush of long silvery hairs. Calyx-tube 
cylindric, silky-pubescent, less densely so below the articulation, }—% in. 
long; lobes broadly ovate or rotund, with sinuate margins, silky-pubes- 
cent on the outside, 14-2 lin. long, 1-14 lin. broad. Petals minute, 
gland-like. Ovary glabrous.—G. baumiana, Gilg in Baum, Kunene-

Lower Guinea. Angola: Malange, Mechow, 325! Gossweiler, 1021! 1022! by 
the River Chitanda, near Kassinga, 4500 ft., Baum, 211! Kitamba Marsh, Quango 
Flats, Buchner, 676 ; by the River Kuango, Pogge,210 211. Mukenge, Pogge, 1414. 
The bracts of Pogge, 210, are distinctly acute and the leaves are longer and more 
crowded than in the type, in which the bracts are rounded at the apex. It is doubt- 
fully placed in this species, 
Baum 211 (@. baumiana, Gilg) diverges in some minor characters from the type, 
but the differences are hardly sufficient for the constitution of a distinct variety. 
20. G. heterophylla, Gilg in Ann. Istit. Bot. Roma, vi. 98. 
Flowering stems much-branched, glabrous, 20 in. high. Leaves some- 
what remote, stiffly membranous, flat, oval or lanceolate, rounded or 
somewhat acute at the apex, a little narrowed towards the base, glabrous, 
with inconspicuous venation, 4—} in. long, ;4,-} in. broad. Heads 
10—20-flowered, supported on a leafless peduncle 3-1} in. long; involu- 
cral bracts 5-6, reddish-brown when dry, very broadly ovate, rounded 
at the apex, erect, persistent, stiffly membranous, 3 as long as the 
flowers. Flowers 4-merous. Calyx-tube terete, slender, very densely 
clothed with very short adpressed silky hairs, }-} in. long; lobes ovate, 
densely pilose beneath. Petals small, obsolete, membranous, glabrous. 
Fruit crowned by silky hairs.
