Allium

Sect. Allium (Sect. Alliotypus Dumort. , Sect. Porrum (Miller) G. Don ex Koch ). Bulbs ovoid or subglobose; not rhizomatous. Stem usually terete. Leaves linear, flat or fistular, sheathing the lower å or more of the stem. Spathe 1 - or 2-valved, usually beaked and caducous. Perianth cylindrical, campanulate or ovoid, with permanently connivent segments. Stamens usually dimorphic, the outer 3 usually simple, rarely toothed or tricuspi- date, the inner 3 always tricuspidate with a broad flat basal lamina topped by a central anther-bearing cusp and two (rarely 4) sterile, usually much elongated cusps. Ovary with distinct nectariferous pores; ovules 2 in each loculus; stigma entire. Seeds angular.

A diflicult section including many closely allied taxa; bulbs, bulblets and notes on flower-colour may be needed for their separation.
