The Correa is a native of Port Jackson, in New Holland, and commonly termed a Botany-bay plant: it was first raised in the year 1793, from seeds which were given by Sir Joseph Banks, Bart. to J. Vere, Esq. of Kensington-gore, and from a plant in whose collection our figure was taken. It receives its generic title from Mr. Joseph Correa de Serra, a native of Portugal; a gentleman of very distinguished talents as a man of science in general, and botany in particular. Of this genus there are as yet but few species discovered; the Alba grows to a shrub of the height of four or five feet, woody and tough; both stem and leaves are covered with a thick flannelly substance, particularly the under side of the leaves, which gives the whole plant a whitish appearance. It continues to flower through the months of April, May, and June; may be propagated easily by cuttings, should be kept as a hardy greenhouse plant, and thrives best in peat earth.
