broad, oblong or subrectangular, toothed at the truncate apex, often 
keeled down the back, glabrous. Involucre 13-1# lin. in diam., cup- 
shaped, glabrous, with 5 glands and 5 subquadrate or transversely oblong 
toothed lobes; glands subcontiguous, 3—} lin. in their greater diam., 
narrowly transverse-oblong, entire. Ovary acutely 3-angled, glabrous, 
with a rudimentary rim-like calyx at its base, on a very short pedicel and 
only partly exserted from the involucre; styles about 4 lin. long, united 
nearly to the middle, then spreading, entire at the apex. Capsule and 
seeds not seen.

133. E. Johnsonii, V. #. Br. A succulent leafless spiny perennial 
6-9 in, high. Branches 3-angled, flexuous, 4-} in. thick when dried, 
“green, with a white stripe down the centre of each face” (Johnson), 
glabrous ; angles with deltoid tubercles 3~3 in. apart, bearing a pair of 
diverging grey needle-like spines 2-4 lin. long on narrow horny shields, 
decurrent 2-5 lin. below the spines. Peduncles solitary in the axils of 
the upper tubercles, 3—} lin. long, 1-flowered in the specimen seen, but 
probably ultimately 3-flowered. Bracts about 3 lin. long, broadly ovate, 
obtuse, apiculate. Involucre sessile, 2 lin. in diam., obconic cup-shaped, 
glabrous, with 5 glands and 5 broadly cuneate or transversely elliptic 
fringed lobes ; glands 2-1 lin. in their greater diam., erect, transversely 
linear-oblong with parallel, nearly straight margins, sometimes slightly 
2-lipped. “ Flowers (glands?) pinky-yellow ” (Johnson). Ovary much 
exserted on a recurved pedicel, glabrous; styles } lin, long, united at the 
base into a sort of nipple, minutely 2-lobed at the apex. Capsule and

134. E. taitensis, Paw in Engl. Jahrb. xxxiv. 83. A bush 14-2 
ft. high, leafless, spiny, succulent above, becoming woody below. Stems 
«nd branches slender, about 4-1 in. in diam. when dried, with opposite 
or alternate rather distant ascending or erect branches, 4-angled, but 
the older parts subterete and the angles very slightly prominent except 
at the short and very broadly deltoid teeth. Leaves very rudimentary, 
minute, scale-like. Spinesslender, blackish, a pair 1-2} lin. long at the 
‘pex of each tooth and a pair of prickles }—} lin. long (or sometimes 
abortive) 3-2 lin. above them, on long linear dark brown horny shields 
decurrent nearly to the shields below, but not forming continuous horny 
margins to the stem-angles. Flowering-eyes at the apex of the shields 
in the axils of the small prickles. Cymes sessile or subsessile, solitary, 
ultimately with 3 involucres, glabrous. Involucres 1-1} lin. in diam., 
funnel-shaped or sometimes somewhat bowl-shaped, glabrous, with the 
vente united into a slightly 5-crenate rim or here and there separated 
md slight cut-like notches, surrounding 5 broad transverse fringed 
odes. Ovary 3-lobed as seen from above, exserted on a pedicel as long 
#8 the involucre, glabrous; styles 4-% lin. long, shortly united into a
