124 COMPOSIT& (Harv.) [ Geigeria. 
Stam. filaments short, hairy ; anthers prolonged into a coriaceous appen- 
dix, 2-tailed at base. Style of the disc-fl. with obtuse, nearly cohering 
lobes, downy at back near the summit. <Achenes of ray abortive, glabrous, 
with a tuft of hairs round the base, of the disc obovate, very villous with 
tufous hairs. Pappus with thick, white, toothed bristles, few in the 
ray-fl., in many series in the dise-fl. DC. Prod. 7, Suppl. p. 286. 
« A much-branched suffrutex ; the branches striate, shortly nude and one-headed 
at the summit. Leaves alternate, obovate-oblong, subobtuse, cuneate at base, 
mucronate, very entire, canescent-villous beneath, glabrous and one-nerved above. 
Heads solitary. Corolla yellow. Apparently related to Geiyeria and Pegolettia. The 
name is compounded of xupedn, a beehive, and odov, a tooth; in allusion to the 
toothed margins of the cells of the honeycombed receptacle.” DC. 1. c. 
C. Eckloniana (DC. 1. c.) 
Has. District of Uitenhage, Ecklon (fide DC.) 
XXXVII. MINUROTHAMNUS, DC. 
Heads many-fl., heterogamous ; ray-/l. ligulate, female, in one row ; 
disc-ft. tubular, 5-toothed, hermaphrodite, Jnv. scales biseriate, the 
outer shorter, acuminate, inner longer, obtuse, membrane-edged. Recept. 
.... Stam. filaments glabrous; anthers shortly tailed. Style bifid, 
with spreading branches. Achenes obovate? clothed with very abun- 
dant, white woolly hairs. Pappus in two rows, of about 20 straight, 
yellow, toothed bristles, the outer ro rather shorter, the inner more 
rigid. DC. Prodr. 7, Suppl. p. 286. 
“ A suffrutex, with the aspect of Cypselodontia ; branches terete, naked and one- 
‘headed at the summit. Leaves alternate, linear, very entire, glabrous above, ap- 
pressedly tomentose beneath. Ends of the peduncular branches and involucres 
clothed with very short, rufous toment. Corolla yellow. The name is compounded 
of puvupos, slender, and @apyos, a shrub.” DC.l.c. Said to be related to Pegolettia. 
M. phagnaloides (DC. 1. c.) 
Has. District of Caledon, Ecklon (fide DC.) 
XXXVIIL GEIGERIA, Griesselich. 
Heads many-fl., radiate ; ray-/l. uniseriate, female, ligulate ; disc-fl. 
tubular, perfect, 5-lobed, the lobes lanceolate, erect, externally gland- 
scabrous. Ltecept. convex, piloso- or paleaceo-fimbrilliferous. Inv. closely 
imbricate, the outer scales mostly leaf-tipped, the inner horny, acute or 
acuminate. Anthers tailed. Style-branches of the disc-fl. linear-lanceo- 
late, flattened. Achenes subtrigonous, hairy or pilose, beakless, narrowed 
to the base. Pappus biseriate, of 10-16 scales, either all aristate, of 
the outer ones blunt; or all of them toothed. DC. Prodr. 5, p. 482. 
Geigera, Less. Syn. 199. 
Suffrutices, glabrous or scabrous, with rigid, leafy stems, or nearly stemless. 
Leaves alternate, linear or linear-subulate, 1-nerved, quite entire or denticulate, 
gland-dotted on each side of the rib. Heads sessile, either terminal or in the forks, 
or secundly pseudo-lateral on lengthening branches. Flowers yellow. Name in 
honor of Prof. Geiger, of Heidelberg. These plants have many characters of Poly- 
chetia, Less., with which genus several of them have been confounded ; but they 
differ not merely by the double pappus, but by the asteroid style. The in all 
h ; pappus in 
is strongly hygrometric and expands almost immediately aaeee water.
