These leaves with different shapes can be grouped into two distinct categories; the first one is called ovate and includes basal and petiolate leaves, arranged in the form of a rosette, while the second one, the lanceolate, refers to smaller leaves and amplexicaul leaves that emerge after stem elongation.
Leaves are alternate, sessile, scale-like, entire, sometimes decurrent, from slightly auriculate to amplexicaul or even vaginate, glabrous, mostly with salt-secreting glands.
