This species of Aletris was introduced to us, from the Cape of Good Hope, about the year 1789; it is a hardy plant, requiring the same management as Aletris Capensis, that is, to be kept in a dry part of the greenhouse; although the plant should be frequently watered when in bloom, as should mostly all plants, notwithstanding (as in the present instance is the case) their flowering in the winter months. This caution we have thought necessary, as it is a general rule with gardeners during that season, to put as little moisture as possible to their plants, whether in flower or not, to avoid damps. The little difficulty in propagating this handsome species of Aletris, will render it soon common; the roots grow nearly horizontally, and from their joints numberless young plants are produced; which character we were desirous of expressing in the figure, as from thence we have taken our trivial name; but from the size of the work, it was found impracticable. The drawing was made in December 1798, from a plant then in flower, at the Hammersmith nursery: we are nevertheless informed, that from being planted in a light, rich soil, it may be made to grow to the height of three feet; with a spike of flowers, one fourth the length of the flower-stem.
