Morphology General Habit: Annual or perennial herbs, rarely subshrubs, mostly succulent
Morphology Stem: Stems erect or ascending or creeping
Morphology Leaves: Cauline leaves sessile or petiolate, alternate, opposite or sometimes whorled, entire or toothed or lobed Leaves subsucculent or succulent, alternate; rosulate leaves absent
Morphology Reproductive morphology Inflorescences: Inflorescence cymose, occasionally spicate or paniculate or flowers solitary
Morphology Reproductive morphology Flowers: Flowers sessile or pedicellate, (4–)5(–9)-merous
Morphology Reproductive morphology Flowers Calyx: Sepals free or basally united, fleshy
Morphology Reproductive morphology Flowers Corolla: Petals usually free
Morphology Reproductive morphology Flowers Androecium Stamens: Stamens usually twice the number of petals
Morphology Reproductive morphology Flowers Nectaries: Nectary scales small, as many as carpels
Morphology Reproductive morphology Flowers Gynoecium Carpels: Carpels as many as petals, free or basally united; style short
Morphology Reproductive morphology Seeds: Follicles erect or spreading Seeds few to many per follicle.
Distribution: A cosmopolitan genus of nearly 600 species, six of which occur in Iraq.
Note: The name is taken from the Latin name for “house leek”, which is derived from the verb sedo (I sit) because it colonizes flat surfaces such as roofs.
