This plant has been considered by Burmann, Hermann, and other Cape botanists, as an Anemone, to which genus it certainly may as easily be referred as Atragene: but as it has been clearly described by Linnæus, under that genus, we have not hardiness enough to dispute his authority. It is (as the trivial name implies) a native of the Cape of Good Hope, but at some considerable distance within land; whence it requires a dry stove to preserve it, suffering much from damps. It is only since the year 1795, that this plant has been found in our greenhouses; being then introduced by Messrs. Lee and Kennedy, nurserymen, where it has flowered and perfected seeds; which seems to be the only means of propagating it: the soil it prefers is a mixture of peat and loam; flowering about March, or April.
