 whence it has probably been introduced into various i)arts of the Old World. 



25. E. loandensis, N. E. Br. Annual. Stems spreading on the 

 ground, 2-^ in. long, laxly branched, thinly sprinkled all round with very 

 spreading straight hairs. Leaves opposite, shortly petiolate, lv^,-3^1in. 

 long, f-1 J lin. broad, oblong, obtusely rounded at the apex, very "unequal 

 at the base, entire or obscurely toothed at the apex, glabrous on both 

 sides or with a few hairs beneath at the base. Stipules all free, those on 

 the upper side of the stem subulate, those on the under side broader and 

 cut into 2-3 segments. Inflorescence as in E, p'ostrata. Peduncle at 

 first almost obsolete, finally lengthening to J or J lin. long, glabrous. 

 Involucre J lin. long, rather longer than broad, campanulate, glabrous, 

 uniformly reddish, without paler stripes, with 4 glands and 5 lobes ; 

 glands minute, narrowly half surrounded with an inconspicuous or sub- 

 obsolete appendage ; lobes subulate, entire, not ciliate. Capsule § lin. 

 in diam., with pubescent angles, nearly glabrous on the sides. Seeds 

 J lin. long, oblong, 4-angled, minutely tuberculate, whitish.

Allied to E, ^>ro*/ra^a. Ait., and E, granulata, Forsk., but its more loosely 

 branched habit gives it a different appeai'ance from either. From the former the 

 pubescence and stipules, and from the latter the differently shaped i)roportionately 

 longer and glabrous leaves, absence of the characteristic pale stripes on the involucre 

 and want of cilia on its lobes, readily distinguish it. Welwitsch, 647. as distributed, 

 is a mixture, one of the sj^ecimens under this number at Kew being E. granulata. 



26. E. serpens, 77. B. d- K. Nov. Gen. et Sp. ii. 52. Habit and 

 arrangement of inflorescence as in E. prostrata, Ait Stems 3-7 in. 

 long, branching, glabrous. Leaves opposite, shortly petiolate, lJ,-2^1in. 

 fong, 1-2J lin. broad, suborbicular, slightly notched at the obtusely 

 rounded apex, unequally subcordate at the base, entire, glabrous on both 

 sides. Stipules 2 at each node, each pair being united into a deltoid- 

 ovate or deltoid-oblong body, irregularly cut or toothed at the top. 

 Involucres shortly pedunculate, f lin. long, campanulate, with 4 glands
