Of nigella he writes: "Take hede that ye take not to muche of this herbe, for if ye go beyonde the mesure it bryngeth deth."

Eleanour Sinclair Rohde
At the tops and ends of his branches and boughs, it putteth foorth flowers almost like those of nigella, of a whitish and incarnate color, having the fashion of a little bell comming out of a swad or husk, being of the fashion of a small goblet, which husk becometh round, having the fashion of a little apple, or sword's pummell: as soon as the flower is gone and vanished away, it is filled with very small seedes like unto those of yellow henbane, and they are black when they be ripe, or greene, while they are not yet ripe.
