19. G. oliveriana, Engl, d- Gilg in Engl. Jahrh. 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, f-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), i-f 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, J-| in. 

 long; lobes broadly ovate or rotund, with sinuate margins, silky-pubes-

Tbe bracts of Pogcje, 210, are distinctly acute and the leaves are longer and more 

 crowded than in tbe type, in wbich 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 tbe 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, stifily membranous, flat, oval or lanceolate, rounded or 

 somewhat acute at the apex, a little narrowed towards the base, glabrous, 

 with inconspicuous venation, J-| in. long, y^J in. broad. Heads 

 10-20-flow^ered, supported on a leafless peduncle J-lJ in. long; involu- 

 cral bracts 5-6, reddish-brown when dry, very broadly ovate, rounded 

 at the apex, erect, persistent, stiffly membranous, | as long as the 

 flowers. Flowers 4-merous. Calyx-tube terete, slender, very densely 

 clothed with very short ad pressed silky hairs, J- J in. long; lobes ovate,
