Lectotypus (first step designated by BAMPS, 1974b: 133; second step designated here): EQUATORIAL GUINEA. Bioko [Fernando Po]: sine loc., 1860, y. fr., Mann 289 ( K [ K00350392 ]!; isolecto-: K [ K00350393 , K00350394 , K00350395 ]!; P [ P00466313 , P00466314 , P00466315 ]!, S [ S11-26125 ] image seen). = Schefflera mannii var. lancifolia Harms in Bot. Jahrb. Syst. 53: 358. 1915 . Lectotypus (designated here): EQUATORIAL GUINEA. Bioko: sine loc., bud & fl., Mildbraed 6410 ( HBG!) .

Habitat and distribution. – Astropanax mannii is restricted to the mountains of western Cameroon and adjacent Nigeria, as well as the Gulf of Guinea Islands of Annobón, Bioko and São Tomé ( BAMPS, 1974b; APD, 2017), where it occurs in humid forest between 300 and 2,300 m elevation.

Notes. – BAMPS (1974b) indicated Mann 289 at K as the lectotype, citing two additional collections from Cameroon (Mann 1182 and 2168) as “ syntypes ”. However , the protologue only mentions “In Ins. Fernando Po, alt. 5000 ped.” and as a consequence the specimens from Cameroon do not represent original material. A total of four sheets of Mann 289 are deposited at K; we have further lectotypified by selecting the specimen bearing Mann’s original label .

The holotype of Schefflera mannii var. lancifolia at B was presumably destroyed, so we have designated the only known duplicate, deposited at HBG, as the lectotype .
