This species of Protea, though it does not stand among the foremost of its congeners in competition for beauty; yet, has its merits, and those of no small moment, as a hardy green-house plant; for it rarely misses flowering, in the month of May, annually, and its blossoms continue in perfection at least two months. It is seldom hurt by cold or wet, if not exposed to either in the extreme. Is easily propagated from cuttings, made in the month of May, or June; by the same mode as has been described for the increasing the preceding species of the Genus, already figured in this work. We owe the first introduction of this plant to Messrs. Lee and Kennedy, Hammersmith, who raised it from seeds, in the year 1786, received from the Cape of Good Hope. Our figure was made from a plant in the Hibbertian collection. [Illustration] PLATE CCCVIII. CROTOLARIA VERRUCOSA. _Blue-flowered Crotolaria._ CLASS XVII.
