REMARKS Operculicarya hyphaenoides is a well-branched shrub or small tree about 1.5 m tall. It is restricted to SW Madagascar (Fig. 3), where it occurs in xerophytic scrub vegetation on limestone in and around Tsimanampetsotsa National Park. This species can be recognized by its numerous small leaflets with strongly revolute margins and prominently raised venation on lower surface that forms deep cavities between veins. CONSERVATION STATUS With an EOO well below 500 km 2 , an AOO of 300 km 2 and only two subpopulations, one from a protected area (Tsimanampetsotsa PA), Operculicarya hyphaenoides is assigned a preliminary status of Endangered (EN B1ab(ii,iii)+2ab(ii,iii)) based on application of the IUCN Red List threat criteria ( IUCN 2001 ).
