The Ling is distinguished from the Heaths by the botanist because its bell-shaped corolla is concealed by the longer, equally coloured calyx leaves, and below these are four bracts which resemble a calyx. Its leaves are triangular, very minute and densely packed, overlapping each other. Like the Heaths its flowers are persistent, and are to be found bleached but preserving much of their original form, nine or ten months after they opened. The anthers are short, and contained within the corolla, but the style is long, and protrudes. The tough wiry stems attain considerable size in the highlands of Scotland, where they serve many useful purposes. It flowers from July till September. C. vulgaris is the only species. The genus gets its name from the Greek Kalluno, to beautify or adorn, an epithet which all who have visited the moorlands in its flowering season will admit is well-bestowed.
