Alyssum marginatum

Credit: Azmat

  • Alyssum cryptopetalum Bunge

    Doubtfully distinct and very similar in appearance to the previous species, but branches somewhat thickened below the infructescence, plants short, up to 10 cm tall in fruit; leaves oblong-spathulate, forming an involucre below the inflorescence; flowers minute with linear short petals, about as long or shorter than sepals, hardly or not emarginate at apex; siliculae broadly ovate orbicular, c. 4 mm long, 3.5 mm broad with slightly retuse apex; valves slightly to distinctly unequally inflated; style inconspicuous, hardly 0.3 mm long.

    Syntypes: Arabia, Aucher Eloy 228 (G); Iran, Isfahan, Aucher Eloy 4101 B(G).

    Distribution: Arabia eastward to Pakistan.

    This is a more common species in our area than the previous one. It appears that younger plants of this species have often been confused with the above species, 1 but its indistinct very minute style, slightly smaller linear petals with almost entire apex, and short condensed infructescence with siliculae valves almost equally tumid are distinctive. However, there is very close similarity between the two species, and intermediate forms are not lacking.
