Descripcion

Hirsute, perennial and stoloniferous herbs, with short rhizome (crown) often thickened; green runner with rooting nodes and caulinar tripartite stipules. Trifoliolated green opaque leaves, elliptic leaflets with margin serrate and long petioles with loosely pubescence (adpresous) and bipartite foliar stipules. Flowers perfect, solitary, axillary (on long peduncles arising from nodes), 5-merous; calyx and epicalyx persistent and green and slightly pubescent; petals 5, yellow, obovate early deciduous; numerous pistils sessile and free. The styles are persistent in lateral position at the achenes. Stamens in several cicles. Fruiting receptacle scarlet-red, fleshy, insipid and edible. Achenes red, numerous, reniform and prominent. fo. albocaput.- Perennial, stoloniferous herbs with crown often thickened; green runner with rooting nodes and caulinar tripartite stipules. Dark green leaves, trifoliolated and sometimes tetrafoliolated or pentafoliolated, leaflets obovate-eliptic with margin serrate; venation semicraspedodromous (scarcely branched secondary venation). Petiole long, with variable length (5-14cm), green and pubescence. Trichomes: glandular (with pluricellular, uniseriate foot and pluricellular head) and single (unicellular) in epidermis of petiole and leaf blade. Crystals: prismatic and cubic in the mesophyll of the leaf. Flowers axillary perfect (15–25mm diameter), solitary, 5-merous; calyx and epicalyx persistent and green; petals 5, yellow obovate-obcordate early deciduous; numerous pistils sessile and free. The styles are persistent in lateral position at the achenes. Stamens in several cicles. Fruiting receptacles flesh, convex, accrescent, insipid and edible; the fruiting receptacles white, with 60-120 cream achenes, prominent and reniform smoothly; in addition, slight changes in color-achenes of this genotypes were registered, to brown-cream and to cream-pinkish in spring. However, the new fruits of self-plants in others season return to typical cream color (Fig. 2 and 3).
