glomerules 2-5 lin. apart, females in simple few-flowered glomerules 
2-5 lin. apart; bracts 2-glandular; male pedicel 2 lin., female pedicel 
3 lin. long. Male: Calyx globose, closely lepidote, } lin. wide, 2-3-lobed. 
Petals 5, free. Stamens 7-8, 5 outer; extra-staminal glands 5, free. 
Female: Calyx oblong, closely lepidote, + in. long; lobes 5, ovate, 
obtuse, with a gland at each sinus. Petals 5, free. Disk urceolate. 
Ovary closely lepidote; styles 3, each 2-partite. Capsule closely 
lepidote, 3-coccous, } in. long. Seeds not seen. 
Upper Guinea. Southern Nigeria: Oban, Talbot, 691! 694! Cameroons: 
Victoria, near Bimbia, Preuss, 1220! near Amarsi, Winkler, 355! Lom, 700-

This species differs from all the others in its cordate auriculate leaf-bases and in 
its free male petals. It is, therefore, at least sectionally distinct from the remainder 
of the genus.
