Frequent by shady burns and in other damp shady places.

Flower diameter c 1.5-2.5 cm

Flowers not fully open in these pics which were taken in late evening.

ID: Bracts around flowerhead consist of an inner row plus an outer row of much shorter ones, without intermediates between these.  Upper leaves clasp stem with pair of rounded basal lobes.  Styles greenish-black.

Other features: Perennial.  A much more robust plant than Smooth Hawksbeard, but difficult to pin down any definitive difference.  Best point is that on Smooth the upper leaves have backward-pointing lobes at base which are very obviously pointed, i.e. long-triangular and tapering.  On Marsh these lobes are rounded if you ignore the "pointing" effect of the teeth.

Flowers are a deeper yellow than Smooth Hawksbeard.  Involucre always covered with black gland-hairs, as often in Smooth H.  Involucre cylindrical, not bulging at base as in Smooth H.

Note how leaves clasp stem with rounded lobes, quite different from Smooth Hawksbeard
