Many species of this Genus have, hitherto, been arranged as Hermannias, to which they are undoubtedly very nigh affined; in nothing essentially varying, but in the character of the chives, being, in this, placed on honey cups, which are wanting in the other; the same natural appearance however of the junction of the supporters of the tips, being common to both. From this small change of the identity of character, so necessary in our artificial system, they are thrown to a wide distance in classification; the one standing in the fifth, the other in the sixteenth class! The Mahernia odorata is from the Cape of Good Hope, and was sent in seeds to England about the year 1792. It is but a short-lived greenhouse plant, and must be raised every two years, at least, from cuttings; which should be made about the beginning of March, and placed on a gentle hot bed, they will by this means become good sized plants by midsummer. The flavour of the blossoms is exactly that of the Jonquil, it continues to flower through the whole year, but is as yet to be found in few collections, although from its different attractions we have no doubt of seeing it soon in most. Rich earth, of old cow dung, and loam, seems to be the soil it most affects. Our drawing was made at the nursery Hammersmith, in July 1799. [Illustration] PLATE LXXXVI.
