supporting the spines and extend 4-3 of the way down to the tooth below, 
with a pair of spines and a pair of prickles to each tooth. Spines 2-6 
lin. long, diverging, brown; prickles }~1 lin. long, sometimes nearly or 
quite obsolete. Involucres 3 together, sessile in the axils of the teeth, 
13-1? lin. in diam., shallowly cup-shaped, glabrous, bright yellow, with 
5 glands and 5 broadly obovate fringed lobes; glands }-1 lin, in their 
greater diam., transversely oblong, entire, with the inner margin turned 
up in a slight ridge or the middle of it incurved and forming a slight 
lip. Ovary sessile, glabrous; styles 1—1} lin. long, shortly united at the 
base, more or less thickened at the apex, entire or minutely bifid.—Pax

126. E. torta, Pax & K. Hoffm. in Engl. Jahrb. xlv. 240. A 
dwarf succulent, leafless and spiny, about 4 in. high, with numerous 
stems erect from a tuberous rootstock. Stems probably about } in, nm 
diam. when alive, much less dried, unbranched, 4-angled and more or 
less twisted, glabrous ; angles toothed, with horny brown margins inter- 
rupted at the base of the teeth or continuous; teeth 24-5 lin. apart, 
with their upper slope very short and nearly truncate and that below 
the spines gradual. Leaves rudimentary, minute, scale-like. Spies 
in widely diverging pairs 1 lin. long at the apex of the teeth and . 
pair of prickles }-2 lin. long immediately in front of them, directed 
inwards on either side of the stem-angles. Flowers and fruit absent 
from the type specimens.

127. E. angustiflora, Pax in Engl. Jahrb. xxxiv. 82. A dwarf 
much-branched very spiny leafless succulent about 1 ft. high or less. 
Branches ¢-d in. in diam. (less when dried), mostly 4-angled, bar the 
opposing angles constricted so as to form opposite teeth or lobes 4-3 on 
apart and nearly truncate at the top and sloping inwards below the 
spines to form the constriction, sometimes with only 3 spirally pbc 
toothed angles, glabrous. Leaves rudimentary, } lin. long and wer 
as broad, deltoid-ovate, acute; soon deciduous. Spines in pairs at 
apex of the teeth, 2-34 lin. long, slender but very rigid, diverging, corr 2 
brown, with a pair of prickles }-1 lin. long at their base or some 
times nearly obsolete, seated on narrow horny bright chestnut-brow? 
shields, decurrent 14-3 lin. below the spines, but never formung 7 
continuous horny margin to the angles. Flowering-eyes nearly ‘in 
quite touching the apex of the shields. Cymes on peduncles aga 
long, glabrous, very immature in the specimens seen, with 3 involucres, 
the central on a distinct peduncle 4-2 lin. long, subglobose and dl 
lin. in diam., but evidently only in bud, glabrous with 5 glands 
5 cuneately subquadrate fringed lobes; glands immature } hn. * Pax 
half-circular ; lateral involucres in very young bud.—Z. Schinzi,
