H. AUREUM.—South Carolina and Georgia, 1882. This soon forms a neat and handsome plant. The flowers are unusually large, and remarkable for the tufts of golden-yellow stamens with which they are furnished.
H. CALYCINUM.—Aaron's Beard, or Rose of Sharon. South-east Europe. This is a well-known native species of shrubby growth, bearing large yellow flowers from 3 inches to 4 inches in diameter. It is a prostrate plant, with coriaceous glossy leaves with small pellucid dots, and of great value for planting in the shade.
H. ELATUM is a spreading species from North America (1762), growing to fully 4 feet in height, and bearing terminal corymbs of large, bright yellow flowers in July and August. Leaves rather large, oblong-ovate, and revolute. On account of its spreading rapidly from the root, this species requires to be planted where it will have plenty of room.
H. HIRCINUM.—Goat-scented St. John's Wort. Mediterranean region, 1640. A small-growing and slender species, with oblong-lanceolate leaves 2 inches long, and producing small yellow flowers in terminal heads. There is a smaller growing form known as H. hircinum minus. The plant emits a peculiar goat-like odour.
H. MOSERIANUM is a beautiful hybrid form with red anthers.
H. OBLONGIFOLIUM (syns H. Hookerianum and H. nepalensis).—Nepaul, 1823. An evergreen species, about 4 feet high, with oblong, pellucid, dotted leaves, and deep golden, somewhat waxy flowers at the end of summer.
H. PROLIFICUM.—North America, 1758. This is a much branched twiggy shrub, about 4 feet high, with small, linear-lanceolate leaves, thickly studded with pellucid dots. Flowers not very large, five-petalled, and of a pleasing bright yellow colour. The allied if not identical H. Kalmiana is worthy of being included in a selection of these plants.
H. URALUM.—Nepaul, 1823. A neat but fragile species that attains to about a yard in height. Leaves rather small, elliptic, almost stalkless, and perforated with transparent dots. Flowers small and of a bright golden yellow.
H. fasciculatum, H. pyrimidatum, and H. patulum are all worthy of attention, where a good representative collection is of importance. The Hypericums succeed best when planted in a rather sandy and not too dry loam, and they are readily increased either from divisions or by means of cuttings.
