REFERENCE TO THE PLATE.

1. A flower complete. 2. One Petal of the flower, with its Chive, (magnified). 3. The Pointal, (natural size). 4. The same, (magnified).

The Linear-leaved Persoonia, is indigenous to the same clime as the Lance-shaped leaved, given in our last number; grows to nearly the same height, and makes a handsome greenhouse plant, continuing to flower through the autumnal months; and producing good seeds. J. Robertson, Esq. of Stockwell, Surry, raised this species from seeds in the year 1794; with whom it flowered last year, for the first time in England; and for whose kind communication of a specimen in flower, (from which our drawing was made,) we beg our grateful acknowledgment. It is raised by seeds, or cuttings; and should be planted in peat earth.
