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 B1. Its area of occupancy (AOO) is estimated to be 132 km ², within the limit for “Endangered” status under criterion B2, 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.
