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.
