Taxon Profile     (Last Modified On 12/20/2017)
Description: Shrub or treelet up to 10 m tall, with 3-4-angled branchlets. Leaves oblanceolate to narrowly elliptic, usually condensed at the apex of the twigs. Numerous flowers in glomerules all along the branchlets; almost sessile, small, yellow-beige to white, apparently tubulous, but with actually 5 free petals, pubescent inside. The fruits, are green then red, ellipsoid, 15 x 10 mm when dry. The pollinator of this species is unknown. Due to scattered observations along the Ogooué and Ivindo rivers, dissemination is most probably driven by water.
Habitus: Shrub up to 7 m, Tree
Phenology: This species has been observed with flowers in September and October, and with fruits only in October.
Habitat: Strombosia fleuryana is only known from very partial to seasonally flooded forests. These forests usually form a narrow belt on the edges of lakes and rivers in the Ogooué basin, and consist mostly of exclusive tree species such as Dactyladenia chevalieri (De Wild.) Prance & F.White, Morelia senegalensis A.Rich. ex DC., Martretia quadricornis Beille, Scytopetalum klaineanum Pierre ex Engl., and Cynometra mannii Oliv. Strombosia fleuryana is locally frequent in this habitat, but always occurs as isolated plants. It is known from 20 to 190 m in elevation.
Distribution: Gabon (endemic)
Distribution Note: Due to recent efforts in inventory of this species, it is now known from more than 15 specimens in more than 10 different locations. It has been collected three times in the lakes near Lambaréné, once along the Ogooué river near Ndjolé, and once along the Ivindo river. It is very likely to be found elsewhere in similar habitats occurring in the Ogooué basin.
Phytogeographical type: This species is endemic to Gabon, with a linking Coastal-Continental phytogeographical type.
Note: This species with a very strong ecological preference was described from the lakes near Lambaréné, but a recent collection along the Ivindo (Bidault et al. 2167) significantly expanded its known distribution. It is also the first collection of this species’ fruits.
More literature: This recently described species has not yet been mentioned in literature.
Case Study: Lower-Ogooué, Ivindo

Conservation assessment     (Last Modified On 12/20/2017)
Red List Category: Near Threatened
Status of Conservation Assessment: Preliminary
Note: This species has been preliminarily assessed in 2017, following the Categories of the IUCN Red List, using Criterion B, by the ConR routine. Based on more than 10 different locations (sensu IUCN), it has been preliminarily assessed as NT. Nevertheless, a formal assessment remains necessary, including a complete review of the available material with emphasis on their location to assess whether the subpopulations should be considered as still present or probably extirpated. Only a full IUCN Red List assessment can conclude on this species being threatened or not.
