This little plant much resembles our Corn Spurry, or Spergula arvensis, at first sight. It is a native of the Cape of Good Hope, seldom grows more than six inches high, and is very apt to be destroyed by the damps of our winters. It should be placed in the airyest part of the greenhouse, and kept in light sandy loam. To propagate it, the cuttings should be put in, about the month of March, in the heat of a gentle hot-bed, or the bark-bed of the hot-house; the seeds are sometimes perfected. It has been often introduced to us, but as often lost; as it is not a plant of much shew, no great deal of pains has, hitherto, been taken for its preservation. Our drawing was taken from a plant in the Hibbertian Collection, in the month of July, 1802. [Illustration] PLATE CCCXXVII. XERANTHEMUM ARGENTEUM. _Silvery Everlasting-Flower._ CLASS XIX.
