General description:- Summer-dormant perennial, with rather large, onion-shaped
bulbils in the axils of the basal leaves at ground level.

Stem:- Flowering stem 10-40 m, erect, usually solitary, sometimes a few together
to form a lax clump, with short-spreading (patent) glandular-downy hairs
(pubescent).

Leaves:- Basal leaves in a rosette, with soft, multicellular, glandular and
eglandular hairs; leaf-stalk (petiole) 1.5-2 times as long as the leaf-blade (lamina),
widened above; lamina 10-20 x 2-25 mm, heart-shaped (cordate), flaccid, with 5 -13
shallow lobes, Cauline leaves stemless (sessile), fan-shaped (flabellate), without
bulbils, the upper ones gradually smaller and more distant.

Flowers:- Inflorescence a rather compact cyme of 5-11 flowers; flower stalks
(pedicels) up to 20 mm. Sepals 2.5-3.5 run, ovate-oblong, subobtuse, green,
glandular-pubescent. Petals 8-12 mm, narrowly obovate, obtuse, 3- to 5-veined,
pure white, sparsely glandular-pubescent on upper surface. Stamens less than half
as long as the petals. Ovary 3/4 inferior; styles very short.

Fruit:- Seeds 0.5 : 0.35 mm, ovoid, brown, with longitudinal rows of short papillae.

Key features:-
1) With rather large, onion-shaped bulbils in the axils of the basal leaves at ground
level.
2) Lamina 10-20 x 2-25 mm, orbicular-reniform, flaccid, with 5 -13 shallow lobes,
3) Petals 8-12 mm, narrowly obovate, obtuse, 3- to 5-veined, pure white, sparsely
glandular-pubescent on upper surface.

Habitat:- Seasonally damp places, open woodland and rub, rock ledges in ravines,
etc., on various substrates, 0-1200(-1750) m.

Distribution:- Almost throughout Greece although rare in the S Aegean area and
the Ionian islands. Spain and N Portugal, NW Africa, S Italy (incl. Sicily) and

usually alternate or basal, rarely opposite, exstipulate; foliar glands (other than
hydathodes), if present, superficial or on hairs, not immersed as in Bergenia.
