B. sinuata, Presl. reliq. Hank. 2. p. 38. Petals 10, pale yel- 
low. Filaments all dilated. Stigmas 3-lobed. This species does 
not turn black on drying, as in the other species, and is readily 
distinguished from them by the beautiful white down on the stem.

Cult. The seeds of the species should be raised in a gentle 
heat in spring; and when the plants are of a proper size, they 
should be potted separately in small pots, and shifted from size to 
size of pots as they grow; the pots should be well drained with 
sherds ; and in the winter they should be placed on a dry shelf 
in a greenhouse or frame. The flowers are very showy, and the 
plants are therefore worth cultivating in every garden.
