and often large, the spreading pedicels 9-15 lines long ; sepals pink or crim-

acuminate, 5-8 lines long: pedicels slender 4-8 lines long, erect to some- 
what recurved: segments of the perianth white to pinkish, lanceolate, acu- 
minate, about 3 lines long, scarcely exceeding the stamens and style: cells 
of the ovary bordered by a thick obtuse ridge. In moist places in the

densely many-flowered: pedicels 4-6 lines long erect or ascending: seg- 
ments of the perianth oblong or almost linear, obtuse or barely acute,
