The collection by Leroy of complete material of this interesting species shows 

 that E. glomerijlora. Pax, and E. venenifera. Pax, are the female and male of the 

 same species. In Leroy's, as in Hildebrandt's, Stuhlmann's and Holtz's specimens, 

 the inflorescences are 1-sexual, but one of Leroy's specimens is interesting in having; 

 one male catkin and many female cymules on the same leafy twig. The species 

 is the representative in Africa of the South-Eastern Asiatic E. Agallocha, Linn.

 eglandular, shortly cup-shaped, limb truncate, denticulate. Stamens 

 8-20 ; filaments prolonged into the connective and connate in a stout 

 somewhat dilated column almost flattened at the apex, which rises

 distinct and parallel, in 2 or more whorls round the upper portion of 

 the column. Kudimentary ovary 0. Female : Calyx coriaceous, 

 eglandular, widely cup-shaped ; limb truncate, quite entire, loosely 

 enveloping the ovary. Ovary 5-20-celled ; ovules in each cell solitary ; 

 styles connate in a long fleshy column with as many radiately divergent 

 undivided arms. Capsule large, depressed, the whorled woody cocci 

 sepai-ating explosively from the columella. Seeds laterally compressed,

 broad, suborbicular, flat. — Lofty trees. Leaves alternate, petioled, 

 broad, closely penninerved. Male flowers in terminal peduncled oblong 

 stout spikes ; each flower solitary to its bract, subsessile ; bracts mem- 

 branous, at first closed and enveloping the buds, at length irregularly 

 torn by the expanding flower. Female flowers solitary, basal to the 

 male spikes or in the upper leaf -axils, distinctly pedicelled ; pedicel 

 stout.

 occasionally naturalised.
