In Bull. Herb. Boiss. vi. 741, Pax describes this and other species as having a 

 thick rieshy trunk. This is an error, as the only one among all tliat lie enumerates 

 wiiich has such a trunk is E. Marlothii, Pax { = E. lonylhracleaia, Va,\=^E. Monti 'tri

58. E, tumbaensis, De Wild. Etudes FL Bas- et Moi/en-CJomjo, 

 ii. 21H. Stems cylindric, striate, glabrous, (greyish-brown. Leaves 

 alternate, 2-3 J in. long, 1-1 J in. broad, obovate or oblong, subobtuse or 

 shortly mucronate, tapering into a short petiole, those towards the 

 apex of the stem passing into bracts. Involucres in terminal groups 

 of 3, with peduncles about 1 lin. long, campanulate, glabrous, with the 

 lobes (? glands) deeply divided into 3 linear segments forked at the 

 apex, 1 lin. long; glands 1-1 J lin. in their greater diam., elliptic, 

 entire. Ovary not exserted, glabrous; styles 1 lin. (or more?) long, 

 united at the basal third, entire and slightly thickened at the apex.

I have not seen any species in which the lobes of the involucre are divided into 

 linear forked segments as described by De Wildeman, but if, as I suspect, the glands are 

 intended, then this plant must be closely allied to, if not identical with,£^. Cervicornu, 

 Baill. 



5H. E. xnacrophylla. Pax in Encjl. Jahrb. xix. 122. Probably 

 perennial, about Ij ft. high in the specimens seen, with simple stems 

 12-14 in. long and \ in. thick, bearing at the apex a 3-5-rayed umbel, 

 with simple or forked rays 3-8 in. long, when simple (from the abortion 

 of one of the 2 branches which arise under each involucre), with 2-3 

 distant flowering nodes, glabrous. Leaves on the stem rather few and 

 somewhat distant, alternate, with a whorl of 3-5 at the base of the 

 umbel, subcoriaceous, 2|-6 in. long, IJ--^ in. broad, those on the stem 

 obovate or oblanceolate to elliptic, obtuse or rounded at the apex, 

 apiculate, cuneately tapering to a subsessile or shortly petiolate base ; 

 those of the whorl sessile, 2-3 of them usually somewhat oblong, 

 deltoid-ovate or rhomboid-ovate, and the other or others cuneate- 

 obovate, oblanceolate or elliptic-lanceolate, cuneate to nearly sub- 

 truncate at the base, all glabrous on both sides. Stipules none. Bracts 

 sessile, |-2 in. long, and as much or more in breadth, suborbicular or 

 very broadly ovate, obtuse or rounded, apiculate, truncate or slightly 

 cordate at the base, glabrous. Involucres on peduncles 1 j--J lin. long, 

 solitary, about 4 J lin. in diam., and 2-2f lin. deep, broadly cup-shaped, 

 glabrous, with 5 glands and 5 transversely rectangular lobes, minutely
