Mozamb. Distr. German East Africa: Ubungu; on the Olunga Mountains, 
4900 ft., Goetze, 1095! 
Described from the type. This is extremely like Z. Schinzii in appearance, but 
the pedunculate cymes, with the central involucre also pedunculate, easily distinguish 
it from that species, 
128, E. tetracanthoides, Pax in Engl. Jahrb. xxx. 342. A 
leafless spiny succulent, 8-12 in. high and up to 2 ft. indiam, Branches 
4-5 lin, in diam. when dried, 5-7 lin. when alive, 4-angled, glaucous. 
Angles subeompressed, crenate or with broadly rounded teeth. Leaves 
rudimentary, scale-like, deltoid, acute. Spines 1-2 lin. long, in pairs 
t-} in, apart, diverging, grey, with a pair of minute and often re- 
curved prickles near their base, on horny grey shields decurrent nearly 
or quite to the flowering-eyes below, occasionally forming continuous 
horny margins to the stem-angles. Flowering-eyes touching the apex 
of the shields but not enclosed in them. Cymes solitary, probably 
Sessile, with 3 involucres, but very immature.—Pax in Engl. Jahrb.
