accrescent, 1.2-2.5 mm. long, acute or acuminate, conspicuously punctate; 
petals linear-lanceolate, 5-8 mm. long, inner surface papillose-tomentose, usu- 
ally to base, conspicuously punctate in lines; stamens up to 3.8 mm. long; 
filaments thick, glabrous, 12 mm. long, punctate; anthers ovate-lanceolate, 
2-2.5 mm. long, thick, apiculate, dorsifixed one-third above base, black-punctate
