Arnebia
(its Arabian name). ORD. Boragineoe. Handsome hardy herbaceous perennials or annuals, allied to Lithospermum. Cuttings should be removed with a heel in autumn, dibbled in sandy soil in small pots, and placed in a cool house, where they will ultimately, though slowly, root; they should then be gradually hardened off, and finally planted out. A. echioides is also easily increased by making cuttings of the strong roots, which should be dibbled in pots of sandy soil, and placed in gentle heat; it is also raised from seed. A. echioides (Echium-like).* fl. bright primrose yellow, with a purplish spot in the sinuses between the lobes of the corolla, which gradually disappears in a few days; spikes terminal, large, solitary, secund. May. l. sessile, alternate; margins-as well as the stems-ciliated. h. 9in. to 12in. Armenia. One of the showiest of hardy perennials for the border or rockery. A. Griffithii (Griffith's). This differs from above in having narrower leaves, rather smaller flowers, which are of a more decided yellow, a differently shaped calyx, and a longer corolla. h. 9in. North-west India. Equally desirable, were it a perennial; but, being an annual, it must be constantly raised from seed.
