14, E. glaucella (Pax iu Bull. Herb. Boiss. vi. 7;i7) ; annual, 

 2-1-3 in. highj in very small plants unbranched, when more fully 

 developed -with about 3-6 ascending main branches, 1-6-times forked, 

 glabrous ;-leaves all opposite or some of the lower alternate, with a 

 whorl of 3 at the apex of the main stem, petiolate, glabrous on 

 both sides; peti<»le ^-4 lin, long; blade ]^-^)y in. long, 1—4 lin. 

 broad, linear, linear-lanceolate, oblong, elliptic or suborbicular, 

 obtuse and apiculate or minutely 3-toothed or acute at the apex, 

 otherwise entire, rounded or cuneate at the base ; stipules very 

 minute or absent ; involucres solitary in the forks of the brandies 

 or terminal, shortly pedunculate, |-1 lin. in diara., somewhat sub- 

 globosely cup-shaped, glabrous, with 3-5 (usually 4) glands and 4-5 

 short oblong or subquadrate bifid or subentire fringed lobes ; glands 

 ■J— I lin. in their greater diam., transversely obhmg or elliptic, 

 entire, with a narrow firm (not petal-like) rim along the outer 

 margin, green; capsule IJ-H li^- ^^ diam., often rather longer 

 than broad, exserted on a slender pedicel and thinly sprinkled with 

 minute stout adpressed hairs or glabrous ; styles about \ lin. long, 

 free to the base, bifid at the apex; seeds 1-1^ lin. long, oblong, 

 subtruncate at each end, dorsally flattened, labyrinthically tuber- 

 culate-rugose or scrobiculate-tuberculate, dark brown (perhaps 

 when immature) or bluish white, with a pale yellowish or whitish

15. E. phylloclada (Boiss. in DC. Prodr. xv. ii. GG); annual or 

 perennial, with radiately spreading or prostrate branches 1-G in. 

 long, in the larger specimens repeatedly branched, glabrous ; leaves 

 and bracts on the branches all opposite, sessile, often crow^ded and 

 imlM'icate on the flowering parts, forming head like masses, !-§ in. 

 long and as much iu breadth, broadly cordate-ovate or orbicular- 

 ovate, obtuse or acute, raucronate, coriaceous or perhaps somewhat 

 fleshy, with a narrow subcartilaginous white or reddish margin, 

 green, with a large white or whitish ai-ea at the base or occupying 

 half the leaf on one side of the midrib ; leaves on the young main 

 stem below the primary branches alternate, ^-Ij- in. long, spathu- 

 lately obovate or orbicular-obovate, obtuse, apiculate, cuneately 

 tapering into a petiole half to two-thirds as long as the blade; 

 stipules none ; involucres solitary at the usually very crowded 

 flowering nodes, siibsessile, 1 lin. in diam., and rather longer than 

 broad, campanulate, thin or somewhat membranous, apparently 

 whitish or purplish, with 4 glands and 5 quadrate or rectangular
