kidney-shaped, very unequally 2-lipped, entire with the margin of the 
large outer lip rounded, very obtuse or folded as if pinched together at the 
apex, often reflexed at the sides. Ovary sessile within the involucre, 
with 3 linear calyx-lobes 1-1} lin. long at its base, glabrous; styles only 
partly exserted from the involucre, 2 lin. long, free to the base, with 
thickened or subcapitate scarcely lobed stigmas. Capsule (Boissier)

This is one of the species that has been mistaken for EH. abyssinica, Gmel. 
Although it bears some resemblance to one of Bruce’s figures, and like Bruce’s plant 
is called “kolquall ” by the natives, yet it totally disagrees with Bruce’s description 
of Z. abyssinica as to its spines and number of stem-angles, The name * kolquall ” 
and its variants also appears to be indiscriminately given to several species of tree- 
like Kuphorbias and is without value for specific determination. The true Z. abyssinica 
would appear to belong to the coast-region, whilst #. controversa is from the interior. 
A. Richard (Pent. Fe. Abyss. ii, 239) mentions that Quartin-Dillon, in a note, has 
Stated that it differs in several particulars from Bruce’s account of the plant, and is 
not used for tanning, but the wood is used for building purposes, &c., which also 
indicates that it is a different species from Bruce’s plant. 
169. E, Murieli, V. #. Br. A large tree with a stout trunk and 
a large dense obconic flat-topped crown of succulent leafless spineless 
branches about as broad as the tree is high. Branches all ascending, 
subparallel, alternately branching, slightly constricted at regular or 
regular intervals, but the joints so formed are of equal diameter 
throughout, 4-angled, with flattish or shallowly concave faces or occa- 
Slonally 5-angled with narrower channels between the angles, but always 
with the solid central part twice or more than twice as broad as the 
narrowly wing-like or slightly compressed angles, in the branchlet seen 
1-1} in. square; angles with even margins, glabrous, Leaves rudi- 
mentary, less than 1 lin. long and about 1 lin. broad, triangular, acute, 
perhaps sometimes larger, as the specimen seen is very imperfect. 
Spines none on the specimen and not evident on a photograph ; spine- 
Shields horny, containing the flowering-eyes, 24-33 lin. long and 2 lin. 
broad, oblong, 3-5 lin. apart, not connected by a horny border. Cymes 
tn dense masses at the ends of the branchlets, with peduncles 4-{ in. 
long, bearing 3 involucres, with the lateral on branches }-} in. long, 
glabrous, Bracts thin, suborbicular, about 1} lin. in diam., very obtuse, 
“oneave. Involucres about } in. in diam., cup-shaped, glabrous, prob- 
ably yellow, with 5 glands and 5 short broad transverse fringed lobes ; 
glands erect in dried flowers, contiguous or subcontiguous, about 14 lin. 
im their greater diam., transverse, reniform, with the inner margin 
turned in, forming a lip, and the outer margin wavy or somewhat 
recurved at the sides. Capsule exserted on a stout pedicel 23-3 lin.
