spurs in the forks, perhaps slightly 4-angled, glabrous, brown. Leaves 

 opposite at the forkings of the stem and about 4 in a tuft at the 

 thickened apex of the branchlets and of the very short thick flowering 

 spurs in the forkings, spreading, subsessile or very shortly petiolate, 

 J-| in. long, ^-h lin. broad, linear, acute, with a recurved or hooked 

 point, glabrous on both sides. Involucres 1-8 together amid the leaf- 

 tufts, on peduncles about -J lin. long, immature, about 1 lin. in diam., 

 cup-shaped, glabrous, with 5 glands and 5 small fringed lobes ; glands 

 scarcely J lin. in their greater diam., transversely oblong, entire. Ovary 

 and fruit not seen.

36. E. macra, Jliei-n in Cat. Afr. PL Wehn. i. 041. Perennial, 

 very variable in appearance. Rootstock woody or perhaps a tuber with 

 a long woody neck. Stems few or many, 2-11 in. high, erect, \-\ lin. 

 thick at the base, 2-3-times forked, in the taller specimens with long 

 slender internodes, glabrous. Leaves all opposite, with the pairs in 

 dwarf specimens \-\ in. and in tall specimens lJ-3 in. apart, sessile, 

 J-1 in. long, \-\h lin. broad, usually linear, sometimes linear-lanceolate 

 or lanceolate, acute, in dried specimens often with inroUed margins, 

 entire, glabrous on both sides. Stipules none. Involucre solitary in 

 the forks of the stem or terminal, subsessile, about IJ lin. in diam., 

 cup-shaped, with 4 glands and 5 subquadrate lobes minutely toothed at 

 the truncate apex, glabrous outside ; glands about J lin. in their greater 

 diam., transverse, narrowly oblong, somewhat 2-lipped or the inner 

 margin inflexed, entire or indistinctly crenulate on the outer margin. 

 Capsule about 2 lin. in diam. and rather more in length, glabrous ; 

 styles J-1 lin, long, erect in a cluster, united below, minutely bifid at 

 the apex. Seeds 1 \ lin. long, oblong, 4-angled, with irregular flattened 

 tuberculate sculpturing and raised flattened margins to the two inner 

 sides, pale greyish- white. — E. tenella. Pax in Bull. Herb. Boiss. vi. 73S,
