Tuberous Moschatel, or Hollow-root; a genus of the tetragynia order, belonging to the octandra clasps of plants. This is a native of the woods in Britain, and several parts of Europe: it is a very low plant, seldom rising more than four or five inches high; the leaves resemble those of bulbous fumitory; the flower-flask arises immediately from the root, on the top of which grow four or five small flowers of an herbaceous white colour, which appear in the beginning of April, and the berries ripen in May; soon after which, the leaves decay. The herb may be procured by transplanting the roots any time after the leaves decay, till winter. They must be planted in the shade, under shrubs; for they will not thrive if exposed to the sun. The leaves and flowers smell like musk, from whence it has by some been called musk-crosswort.
