( Fig. 1G–H View Fig , 7C–D View Fig ).

Pseudosabicea nobilis (R.D. Good) N. Hallé, Fl. Gabon 17: 2. 1970.

Lectotypus (designated here): ANGOLA. Cabinda : Belize , 16.XI.1918, fl., Gossweiler 7550 ( BM [ BM000902997 ]!; isolectotype: K [ K000414624 ]!, LISC [ LISC000807 , LISC000808 ] images seen). Syntypus: ANGOLA. Cabinda : Belize , 12.III.1917, fr., Gossweiler 7043 ( BM!, LISC [ LISC000809 , LISC000810 , LISC000811 ] images seen).

= Pseudosabicea mitisphaera N. Hallé in Adansonia ser. 2, 3: 170. 1963. Holotypus: GABON. OgoouéIvindo : piste du Bouéni , env. 20 km SE Makokou, 11.II.1961, N. Hallé 1129 ( P [ P00077593 ]!; isotype: BR [ BR0000008852137 ]!, K [ K000414625 ]!, LISC [ LISC002621 ] image seen, P [ P00077594 ]!).

Distribution, ecology and phenology. – Sabicea nobilis occurs in southeastern Cameroon, Gabon (mostly in the east, absent from the coastal area), southwestern Congo Republic, and Angola ( Cabinda) ( Fig. 9 View Fig ) and is locally common in its range. It is found in secondary forest, edges and regrowth, always on drained soils, 160–800 m in elevation.

Flowers have been collected from May to August and October to January; fruits from January to May and September to November.

Conservation status. – The extent of occurrence ( EOO) of S. nobilis is calculated to be 238,406 km ², well above the limit for “Vulnerable” status under subcriterion B 1. Its area of occupancy ( AOO) is estimated to be 132 km ², within the limit for “Endangered” status under criterion B 2, but this is an obvious underestimation since most of its range is not well explored. It occurs in Atlantic Central Africa from southeastern Cameroon to Cabinda ( Angola) and is known from 43 specimens representing 30 subpopulations. It occurs in two protected areas, the Doudou Mountains National Park and Batéké Plateaux National Park in Gabon. It is a locally abundant plant of forest edge habitats, and is thus favoured by small-scale forest clearing. Furthermore, most of the area where it occurs is sparsely populated. As a result, there is no particular threat to the species, which is here assessed as “Least Concern” [LC] using the IUCN Red List Categories and Criteria ( IUCN, 2012).

Notes. – The original description of S. nobilis ( GOOD, 1923) is based on two syntypes, Gossweiler 7043 and 7550, both at BM; the latter collection is here selected as lectotype, because it has a larger number of duplicates.
