l|'-3' in length. Flowers from the middle to the end of July, f '-|' long, on stout sparingly 

 pubescent pedicels, in mostly 7-10-flowered thin-branched glabrous cymes; peduncle 

 slender, glabrous, the free portion l$'-lf in length, its bract gradually narrowed and cu- 

 neate or rounded at base, narrowed and rounded at apex, glabrous, 4'-5|' long and '-!' 

 wide, decurrent to within %?'-%' of the base of the peduncle; sepals ovate, acute, ciliate 

 on the margins, covered on the outer surface with short pale pubescence and with silky 

 white hairs on the inner surface; petals lanceolate, acuminate, twice longer than the sepals; 

 staminodia oblong-lanceolate, rounded at the narrowed apex, as long or nearly as long as 

 the petals; style clothed at the base with long white hairs. Fruit ripening in September,
