Broom, shrubby, and covered with prickles; leaves simple; blossoms of a purplish blue. REFERENCE TO THE PLATE. 1. The Cup. 2. A Blossom, the cup taken off to shew the exact situation and shape of its various parts. 3. The Chives, as they inclose the pointal (natural size.) 4. The Threads magnified, and cut open, to shew their tubular shape. 5. The Pointal, magnified. Owing to the difficulty in propagating and preserving some plants, although frequently introduced to us, and well known; yet are they more scarce to be found, in our best collections, than plants of seemingly more difficult acquisition. This species of Anthyllis has been mentioned under various synonyms by most botanical authors from Clusius downwards. Mr. T. Johnson, in his edition of Gerard of 1633, has given a description of this plant from Clusius, and a cut; both of which are excellent (considering the then infant state of the art of engraving), under the title of Genista spinosa humilis; Dwarf Furze. It is termed Erinacea by Clusius (says he), from the Spanish name of the hedge-hog, Erizo, of which country it is a native, in the kingdom of Valencia: from which we might infer, that, like other plants of that country, it would live through our winters; which is not the case. It must be kept as a greenhouse plant, and watered but sparingly. The soil it prefers is a light loam; is propagated by cuttings, and flowers in April, or May. [Illustration] PLATE XVI.
