Dipsacus pilosus Linnaeus, 1753
Common names: Small Teasel [En], Cardère velue, Cardère poilue, Verge à pasteur [Fr], Kleine kaardenbol [Nl], Behaarte Karde [De], Scardaccione peloso [It]
Hamoir, LIEGE ● Belgium
Description: Cauline leaves shortly petiolate, not connate at base. Heads globose to spherical. Corolla whitish.
Small Teasel is quite definitely a cousin of Wild Teasel (Dipsacus fullonum) in that it has little spines but it is much daintier and has a much rounder flowerhead of white flowers. Out of each of the tiny, funnel shaped, four-lobed corollas protrude four little stamens making the flower resemble a tiny little round pincushion. Below the 15-20mm flowerheads are bristly linear bracts which form a little collar or ruff. The plant is not as sharply prickly as the Wild Teasel, the tips of the bristles ending in soft hairs, 'pilosis' translating as 'covered in soft hairs'.
Biology : It blooms from July to September. In its first year – it's a biennial – it forms a rosette of oblong, toothed, stalked leaves. When the ridged, branched stem grows in the second year it carries the flowerheads and oval stem-leaves up to 1.5 metres.
Habitat: Damp sites, open woodland and hedgerows.
Distribution: Europe, mostly Central, Western Asia, Mongolia and Japan.
