 surfaces ; petiole 1-2 in. Pedjuncles O-J in. ; cymes 10-30-fld. ; bracts J in., linear- 

 lanceolate, deciduous ; pedicels many attaining ^ in. Sepals | in., patently fulvous-

 Seeds glabrous. — L. flavescens, Blume, a Javau species, has the sepals ovate subacute 

 (not acuminate)., the corolla rather shorter and wider at the base than in L. WaUichii.

 densely grey strigose ; but these 3 Asiatic species might perlmps be considered vars. 

 of one.
