Mr. James Donn, Curator of the Botanic Gardens, Cambridge, through whose medium we possess this new species of Crysanthemum, informs us, in his catalogue for 1800, that it is a native of the coast of Barbary, and from whence it was first received in 1797. The C. Tricolor is but of annual growth, should be raised on gentle heat about March, and may be either kept in pots, or planted in the open borders, where it will flower from July till October; but much of the brilliancy of the flowers will be lost, if treated in the last manner, as the least wet, or even the dew, will affect their colours. The seeds are perfected in less than a week, after the decay of the flower, and are produced in abundance. Our figure was taken from a plant in the Hammersmith nursery, which had been raised from seed, communicated by Mr. Donn to Messrs. Lee and Kennedy.
