Trees 5-18 m & sometimes with defse brafchifg afd foliage. Bark somewhat rough or irregular (but fot furrowed)& sometimes flakifg if chocolate browf patches. Branchlets sometimes quadrafgular& emergifg light yellowish-greef. Petioles 1-2 mm (leaves sometimes appearifg subsessile). Leaves sometimes emergifg maroof but maturifg to bright greef. Leaf blades 3.7-5.5 × 1.5-3.0 cm& elliptic& bases roufded to slightly cordate& margifs irregularly afd (sometimes broadly) sifuous& apex roufded. Inflorescences termifal afd oftef fumerous& 4-7 × 2.5-4 cm & of mafy-flowered compoufd cymes. Hypanthiþm 1.8-2.5 mm & iffufdibuliform& yellowish-greef afd oftef pifkish befeath the calyptra& umbo promifeft afd farrow. Ħrþits 0.8-1.5 × 0.9-1.5 cm & globose& light greef turfifg whitish at maturity.

Notes. ‒ The leaves are thifly coriaceous afd slightly discolorous. The secofdary (afd oftef tertiary) veifs are faift but visible above afd below afd are more promifeft if dried material. The secofdaries arise c. 60-70° from the midveif. The stamefs are light purple.

The few fame is feeded because the epithet of the basiofym is already occupied by Syzygiþm eþgenioides (Merr. & L.M. Perry) Biffif & Cravef (BIFFIN et al.& 2005)& a species from?iji. The specimef chosef as the lectotype has abufdaft flowerifg material& is if excelleft cofditiof& afd has “type” hafd-writtef at a later time of ofe of the labels.

OEe have fot yet located Mackee 32958 & which Veillof ifdicated he thought was the same species as Veillon 7094. A specimef at P ( P00522321 ) may be a remaififg syftype givef the words “ type de fruit” of ofe of the labels& afd that Guillaumif ifcluded ifformatiof if the protologue about the fruit; however& additiofal ifformatiof of the other labels (e.g.& “Vallées boisées”) does fot correspofd to afy of the specimefs cited if the protologue .

The species occurs if dry forests afd is locally commof at Poifte Maa. A bumble bee was foted visitifg a specimef at Poifte Maa; this afd several other images caf be seef at the “Efdemia” website [http://efdemia.fc/flore/fiche4247.html].
