*Morina longifolia.—A hardy perennial of handsome and singular appearance, the large spiny leaves resembling those of certain Thistles, while the long spikes of whorled flowers, which are from 2 to 3 ft. high, are almost identical in form with the inflorescence of many of the Labiate family. It grows well in ordinary well-drained soil, preferring that which is mellow, deep, and moist. Easily multiplied by sowing the seed as soon as it ripens, in light, peaty, sandy soil. In our winters it would be advisable to cover the plants with litter, as it is the dampness and sudden changes of the atmosphere which appear to injure it rather than the cold. Being a fine-flowering plant, as well as remarkable for its leaves, it is excellent for every kind of mixed border, and also for grouping with the smaller and medium-sized perennials that have fine foliage or are singular in appearance. Nepaul.
*Mulgedium alpinum.—A tall mountain-plant of the Sow-thistle family, with very broad leaves and stems over 3 ft. high. The flowers are very numerous, of a dark-blue colour, resembling those of the Chicory, and are borne erect on the upper parts of the branching stems. A somewhat shaded position and a very moist deep loam are necessary to the vigorous growth of this plant, which will prove effective in the rougher parts of the pleasure-ground. Multiplied by division. Alps.
*Mulgedium Plumieri.—A vigorous herbaceous perennial, 4 ft. to 6 ft. high, with very large, deeply-cut radical leaves somewhat glaucous underneath, bearing late in summer large spreading terminal corymbs of blue flowers. A good subject for association with strong-growing herbaceous plants in groups, or as isolated tufts by wood-walks, in deep rich soil. S. of France.
