fruit. Sepals ? lin. long, ovate-acuminate, glabrous, very minutely 
papillate. Corolla rotate, 34 lin. in diam., dark purple-brown on the 
lobes, yellowish with dark purple-brown dots on the disk ; lobes 14 lin. 
Jong, 1 lin. broad, ovate, acute, glabrous, papillate outside. Outer 
coronal-lobes small, spreading or deflexed, concave, tooth-like or with

Nile Land. Eritrea: cultivated specimen / frequent around Geleb, Penzig 
(ex Penzig), 
Described from a cultivated plant introduced by Messrs. Dammann & Co. of 
Naples. 
Specimens collected by Schweinfurth & Riva (1273) on the north side of 
Saganeiti towards Selet, 6000-7000 ft., in Eritrea, may belong to this species, but 
there are no flowers on the specimens I have seen. Possibly the Geleb plant col- 
lected by Penzig (which I have not seen) may be EZ, nubica, N. E. Br., which is 
easily distinguished by its very much smaller flowers. 
Probably Boucerosia cylindrica, Brongn. in Bull. Soe. Bot. France, vii. 900, 
should be referred to this species; it was collected by Courbon near Halai, in 
Eritrea. 
4. E. Virchowii, XK. Schum. Monatsschr. fiir Kakteenkunde, iii. 
98, with fig. Habit and general appearance as in Z. cereiformis, Hook 
f., but more slender. Stems 34-5 lin. thick, 6-angled, tessellately 
divided into slightly pronounced tubercles. Flowers subsessile, flat- 
topped in bud. Sepals about } lin. long, ovate, acute, minutely papil- 
late. Corolla about 34 lin. in diam., rotate, 5-lobed to half-way down, 
outside minutely tuberculate, dingy green or dull purplish, inside very 
minutely papillate, either entirely dull greenish or yellowish-green, 
dotted with purple-brown or with the apical part of the lobes entirely 
dull purple-brown ; lobes about 1 lin. long and broad, ovate, acute. 
Outer corona distinct, cupular, rising to the level of the inner, 
obscurely 5-angled, with 5 small minutely apiculate pouches alternating 
with the angles, which are opposite the inner coronal-lobes, dark purple- 
brown, with the inside of the pouches yellowish, spotted with purple- 
brown; inner coronal-lobes deltoid, acute, obtuse or minutely and 
irregularly toothed or bifid at the apex, horizontally incumbent on the 
backs of the anthers and not produced beyond them, dark purple-brown 
indistinctly mottled with dull yellowish.—K. Schum. in Engl. Pf. Ost-
