Gazul bears the greatest affinity to barilla, both in quality and appearance. The principal difference consists in its growing on a still dryer, salter earth, consequently it is impregnated with a stronger salt. It does not rise above two inches out of the ground, spreading out into little tufts. Its sprigs are much flatter and more pulpy than those of barilla, and are still more like samphire. It is sown but once in three, four, or five years, according to the nature of the soil.
Soza, when of the same size, has the same appearance as gazul, but in time grows much larger, as its natural soil is a strong salt marsh, where it is to be found in large tufts of sprigs, treble the size of barilla, and of a bright green colour, which it retains to the last.
Salicor has a stalk of a deep green colour, inclining to red, which last becomes by degrees the colour of the whole plant.
