WOOD AVENS
Geum urbanum
FamiIy ROSACEAE
On the borders of woods, in copses, and on shady hedgebanks, the Avens is abundant.
It is a perennial, with a short, creeping rootstock, frcm which spring the radical leaves, the blade of which is broken up into distinct lobes and toothed leafiets, widely separated, and varying in size and shape, the terminal leafiet very large, the lowest ones very small. The stipules are large and leafy.
The fiowering-stem may reach a length of three feet, bearing erect, soli tary, bright yellow fiowers on lon g branching footstalks. The calyx has five long, pointed lobes, with five pointed bracts. The five petals spread themselves out flat, the calyx lobes showing green between them. The crowd of stamens may not easily be numbered; the carpels, too, are numerous, and develop into a head of nutlets, each with a sharp, curved hook at its tip, by which they catch in fur and feather, and so get distributed by bird and beast.
Flowering chiefiy between June and August.
