* Achyrospermum tisserantii Letouzey View in CoL

Distribution: Cameroon, Central African Republic, D.R. Congo, Equatorial Guinea, Gabon, Republic of the Congo.

Habitat: Rainforest; alt. 800–900 m in D. R. Congo, alt. 150–940 m elsewhere .

Specimens examined: D.R. CONGO: Forestier Central (near the limit of Lacs Edouard & Kivu): Kivu, territoire Walikale, Musenge, 01°38’S, 28°16’E, alt. 800 m, jeune recru, 20 Dec. 1958, A. Léonard 1897 (BR); Kivu, territoire Walikale, Tandalukara, 01°33’S, 28°22’E, alt. 850 m, forêt à Cynometra , Julbernardia et Staudtia , 10 Dec. 1958, A. Léonard 1927 (BR); Nord Kivu, Irangi, 01°53’S, 28°27’E, alt. 900 m, rive droite de la rivière Luhoho, forêt dense à Gilbertiodendron dewevrei et Uapaca guineensis sur pentes fortes, 27 Nov. 1988, Lejoly 88/730 (BRLU); Kivu, Irangi, gîte IRSAC, ± 01°53’S, 28°27’E, alt. 800 m, forêt dense, sous-bois, 24 Mar. 1967, Lewalle 1737 (BR).

Discussion: A. tisserantii was previously known from the Lower Guinean region only. All new localities are located in Kivu, remarkably isolat- ed> 1000 km in the east of the nearest locations. Collectors do not report the white spots on leaves often found in W African specimens, but the constancy of this trait is uncertain.
