§-1 lin. long, united to the middle or beyond, with slightly spreading 
minutely bifid or emarginate tips, glabrous. Capsule and seeds not seen. 
Lower Guinea. Angola: Huilla; sandy plains in the vicinity of the River 
Nene, 5900 ft., Dekindt, 3088! (Antunes 889 according to Pax.) 
Although there is disagreement in the name of the collector and number quoted, 
this is undoubtedly the plant described as E. verticillata by Pax,"as is clearly 
evidenced by the remarkable character of having a whorl of 4 bracts around each 
puberulous involucre as described by him, as well as by being so named in the Paris 
Herbarium. On the label with the specimens from which the above description is 
made, the number 88 has been written, crossed out and 3088 substituted, as if it may 
have been intended to write the number 889 as quoted by Pax and then corrected. 
Antunes and Dekindt collected together during the Huilla expedition and both 
would be likely to collect the same plant and so some confusion may have been made 
in name and number. 
52a, Euphorbia parifolia, V. /. Br. Rootstock an elongated 
tuber, producing 1 or more annual stems branching into a 2~3-rayed 
umbel at the top and with 1 or 2 pairs of branches or sometimes a 
solitary branch below the umbel, 4-9 in. high, glabrous. Leaves and 
bracts all opposite or with a whorl at the base of the umbel, sessile, 
Spreading, subcoriaceous or subfleshy, 4-1} in. long, 2-7 lin. broad, with 
the basal pairs very much reduced or scale-like, lanceolate, elliptic or 
elliptic-ovate, acute, rounded or slightly narrowed at the base, veins 
Subobsolete, some leaves obscurely 3-5-nerved from the base, glabrous 
on both sides and probably glaucous. Rays of the umbel and branches 
below them 2-6 in. long, 1-8 times forked, rather widely diverging, 
glabrous. Involucres solitary, sessile at the tips and in the forks of the 
rays, 13-2} lin. in diam., cup-shaped, glabrous, with 4 glands and 5 
oblong bifid or toothed lobes; glands apparently erect, 3-2 lin. in their 
greater diam., rather narrowly transversely oblong, concave or shallowly 
crater-like, entire. Ovary exserted on a pedicel twice as long as the 
involucre, at first recurved, finally erect, glabrous; styles ? lin. long, 
free to the base, not spreading, bifid at the apex. Capsule about 2 lin. 
in diam. and rather longer than broad, oblong, trigonous. Seeds not 
seen.—Z, verticillata, N. E. Br., on p. 525 of this volume, partly, not 
of Pax. 
Lower Guinea. Angola: Huilla; on a sandy plain, 5600 ft., Antunes, 
1047! (Dekindt 1047 in the Berlin Herbarium is probably an error as to the 
Collector’s name.) 
I was misled into describing this plant as Z. verticillata on p. 525 because 
the specimen of it in the Berlin Herbarium has evidently been mistaken for that 
Species by Pax himself. But now that I have seen specimens in the Paris Herbarium 
that are undoubtedly correctly named EL. verticillata, as well as others of the present 
plant, there can be no doubt as to the perfect distinctness of the two species. The 
conspicuous difference in the arrangement, shape, texture and venation of the leaves 
is at once very apparent, besides the details in floral structure. Concerning the 
disparity in collectors’ names, see note above under Z. verticillata,

Upper Guinea. French Guinea, Paroisse, 201!
