Foulkesweg 37, 6703 BL Wageningen, The Netherlands; corresponding author e-mail: jos. vandermaesen @ wur. nl. yellow or red. Pods black, brown to grey-hairy, rounded-oblong, c. 1 cm long, 1 – 2 seeds. Ecological note — The plants look capable of surviving savannah fires. Except for Adam 27917 all localities are coastal sites. Conservation assessment — Based on an area of extent of nearly 48 000 km 2 and on an area of occupancy of c. 15 000 km 2 when using grid cells of 56 km, E. arenicola would be classified as Least Concern. However, since the most recent collection (Adam 28403) is already 38 years old, at least the Monrovia locality of the species is probably lost, and the actual distribution area along the coast is confined to a very narrow savannah strip that is not considered by both the AOO and EOO calculations, we consider E. arenicola is under quite some threat at present and we assess it as Threatened. Notes — This taxon belongs to the group around E. glomeratum (Guill. & Perr.) Hook. f., of which species Verdcourt (1971) indicated the lectotype: Perrottet s. n. (P, barcode P 00373661), Senegal, Kounoun, 12 mars 1829. It is a smallish specimen with sessile capitate inflorescences, in West Africa difficult to separate from var. elongatum (Baill.) Baker, with pedunculate inflorescences; hence both Verdcourt and Jacques-Félix (1971) synonymised the latter with var. glomeratum. However, in Flore du Congo-Belge et du Ruanda-Urundi Hauman (1954) kept var. elongatum apart, and the specimens are reasonably easy to sort in the more central part of Africa. In Flora Zambesiaca both these taxa are absent, apart from a mention as doubtful (Verdcourt 2001). Hepper in Flora of West Tropical Africa (1958) quoted Deighton 2679 and Dinklage 3279 under E. glomeratum as undescribed sea coast forms. In the Flore Analytique du Bénin (Akoègninou et al. 2006) and the Checklist of Gabon (Sosef et al. 2006) E. laurentii was considered a variety of E. glomeratum, but upon further consideration it is distinct enough to merit the rank of species, just as Hauman (1954) and Jacques-Félix (1971) preferred. As is apparent from Map 2 and 3 these two species have a different distribution and hence ecology. Eriosema laurentii occupies a habitat that, albeit savannah, is closer linked to the forested areas than E. glomeratum, the latter avoids the dense forest region as a whole.	en	Maesen, J.
