Abstract

The teasel family consists of 11 genera of 350 herbs and shrubs found in temperate climates. Containing both perennials and biennials native to Europe, Asia and Africa, a single species has been introduced to Nova Scotia. Leaves are generally opposite or whorled. The flowers are borne in dense cymelike heads. Flowers are sympetalous and mostly perfect, the corolla 4–5-merous. It appears to be bilabiate. Stamens number four. Calyx is deeply cleft into 4–5 lobes. Ovary is inferior in position and contains a single locule. Dry fruit is enclosed by the persistent involucel.
