The branches of this plant seem always to originate from buds in the axils of the 

 cluster of leaves at the base of the peduncle, never from those of the alternate leaves 

 on the lower part. After fruiting the leaves and umbels fall, and the next season's 

 growth is developed from the apex of the previous year's branches. 



61. E. Engleri, Pax in Engl. Pfl. Ost-Afr. C. 242. A tree 

 (Johnston). Stems or branches of the specimens seen herbaceous or 

 sub-woody, lJ-2 Jin. thick, terete, glabrous. Leaves alternate, thin, 

 2J-G in. long, |-2 in. broad, lanceolate, acute or acuminate and apiOulate 

 at the apex, tapering from above or below the middle into a petiole 

 J- J in. long, glabrous on both sides. Stipules none. Umbel terminal 

 or with the branch ultimately developing beyond it, composed of o-6 

 rays 2-5 in. long, once or twice forked, glabrous. Bracts 2J-G in. long, 

 l|-5 lin. broad, elliptic or elliptic-ovate to suborbicular, obtuse or 

 rounded at the apex and base, apiculate, glabrous on both sides. Invo- 

 lucres on very short peduncles, solitary in the forks or at the ends of 

 the ray-branches of the umbel, about 2| lin. in diam., cup-shaped, 

 glabrous, with 4 glands and 5 subquadrate-ovate lobes, minutely 2-toothed 

 at the apex and ciliate ; glands |-1 lin. in their greater diam,, trans- 

 versely oblong, half-circular, or subrectangular, with 2 teeth or short 

 horns, sometimes reduced to minute points at the outer angles. Capsule 

 3-3J lin. in diam., glabrous, exserted on a long recurved pedicel ; styles 

 about I lin. long, very shortly united at the base, rather deeply bifid at 

 the apex, suberect. Seeds If lin. long, subglobose-ellipsoid, tuberculate.

On the respective labels. Sir Harry Johnston states that this is a tree and Volkens 

 that it is a laxly branched shrub 10 ft. high, 1 find no difference whatever between 

 E. Eugleri and E. pseudo-engleri, both leaves and glands vary considerably when a 

 sufficient number of specimens is examined.
