7a. Sabicea sanguinosa subsp. sanguinosa View in CoL

( Fig. 2E–F View Fig , 12E View Fig ).

Distribution, ecology and phenology. – This subspecies is endemic to coastal Gabon, occurring in the Wonga-Wongué reserve and slightly further north (Nyonié) ( Fig. 10 View Fig ) and grows in forest edges on coastal sandy soils, up to 150 m in elevation.

Flowers collected in January (buds), February, and from May to July; fruits in January-February and August.

Conservation status. – The extent of occurrence (EOO) of S. sanguinosa subsp. sanguinosa is estimated to be 860 km ², and its area of occupancy (AOO) to be 32 km ²; both values fall within the limit for “Endangered” status under subcriteria B1 and B2. The taxon is endemic to coastal Gabon, and is known from nine specimens, representing five subpopulations, all but one of which occur in the Wonga-Wongué Presidential Reserve. Its situation is rather comparable to that of the species as a whole, and it is assessed as “Least Concern” [LC] for the same reasons using the IUCN Red List Categories and Criteria ( IUCN, 2012).
