16. AN6MALAE Sarg. Leaves elliptical to ovate, finely and doubly serrate 

 or lobed, acute at the apex, abruptly cuneate to rounded at the base, subcori- 

 aceous or membranaceous, bright green above, pubescent (particularly along 

 the veins beneath); petioles slightly winged above, 1-4 cm. long; corymbs 

 many-flowered ; calyx-lobes lanceolate, acuminate, glabrous outside, slightly 

 pubescent within, glandular-serrate; stamens 6-20; anthers pink ; styles

 thin succulent or glutinous flesh; nutlets usually 2-4, commonly having a 

 shallow pit on the ventral face (a feature often lacking in individual nut-
