Allium guttatum Steven

Οικογένεια: Alliaceae
Allium guttatum Steven
Bulbs 1-2 cm in diameter, ovoid; outer tunics membranous or coriaceous, sometimes breaking into parallel fibres; bulblets yellowish. Stem 10-90 cm. Leaves 2-5, up to 30 cm Χ 3 mm, filiform, semi-terete or flattened, fistular, sheathing the lower 1/3-2/3 of the stem. Spathe 1-5 cm, 1-valved, with beak 1·5-4 cm, caducous. Umbel 1·5-5 cm in diameter, subglobose, ovoid or hemispherical, many-flowered; pedicels unequal, the central erect in fruit and up to 30 mm, the outer much shorter and deflexed, thus sometimes forming an apparently double umbel, with large membranous bracteoles at base like an involucre. Perianth cylindrical; segments 2·5-4·5 Χ 1-1·2 mm, the outer oblong, keeled, obtuse or subacute, the inner narrowly oblong-spathulate, truncate-rounded, smooth. Stamens exserted; outer 3 filaments 3·5-4 mm, simple, the inner 3 with the basal lamina slightly longer than the central cusp, the lateral cusps usually much longer than the central cusp; anthers yellow or dark red. Capsule c. 3 mm. Dry places. (Περιγραφή απο Flora Europaea)

Είδος με εξαιρετική ποικιλομορφία, ειδικά στο μέγεθος. Κάποια άτομα, συνήθως δίπλα στη θάλασσα, μικρά σε μέγεθος, είχαν αναγνωριστεί παλαιότερα σαν Allium staticiforme αλλά πρόκειται μάλλον για μια απο τις μορφές του Allium guttatum, ίσως το υποείδος Allium guttatum subsp guttatum. Περισσότερες πληροφορίες στη Χλωρίδα μας (σαν Allium staticiforme), Φυτολόγιοgreekflora.gr, Flora of Greece.
