 minutely bifid or emarginate tips, glabrous. Capsule and seeds not seen. 



Ziower Guinea. Anp:ola : Huilla; sandy plains in the vicinity of the River 

 Nene, 5900 ft., Bekindt, 3088 ! (Antunes 889 according to Pax.) 



^ Although there is disagreement in the name of the collector and numher quoted, 

 this is undoubtedly the plant described as E. verticillata by Pax, as is clearly 

 evidenced by the remarkable chiiracter of having a whorl of 4 bracts around mch 

 puberulous involucre as described by him, as well as by being so named in the Pari« 

 Herbarium. On tlie label with the specimens from which the above description ia 

 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 ajid tlien corrected. 

 Antunes aiid 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, N. E. 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, J-1 J 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, 1-3 times forked, rather widely diverging, 

 glabrous. Involucres solitary, sessile at the tips and in the forks of the 

 rays, l^-^J hn. in diam., cup-shaped, glabrous, with 4 glands and 5 

 oblong bifid or toothed lobes; glands apparently erect, §-J 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. — E. verticillata, N. E. Br., on p. 525 of this volume, partly, not 

 of Pax. 



Ko-wer Guinea. Angola: Huilla; on a sandy plain, 6600 ft., Antunes, 

 1047 ! {Dekindt 1047 in the Berlin Herbarium is probably an error as to the 

 collector's name.) 



I was misled into describing tliis plant as E. verticillata on p. 525 because 

 the specimen of it in the Berlin Herbarium has evidently been misUiken for that 

 species by Pax himself. But now that I have seen specimens in the Paris Herbarium 

 lliat are undoubtedly correctly named E. 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 E. verticillata.
