In recent years, it has become customary to separate the annual species of Salicornia ( Salicornia s.s.) from the perennial species ( Sarcocornia), a separation that is also supported by details of the flowers and their position. However, Sarcocornia has been shown to be composed of two separate clades with Salicornia derived from within it (i.e., the genus Sarcocornia is not monophyletic; Kadereit et al. 2007). Therefore, an inclusive Salicornia is recognized here that includes annual and perennial species. Measurements in the key are based on fresh material.

1b. Plants annual, without rhizomes; the middle flower of each cluster conspicuously elevated above the 2 lateral flowers [Fig. 340]
2b. Leaf and scale apex rounded to acute [Fig. 340], without a mucro; inflorescence 2.9–5 mm thick, usually of similar thickness to that of the stem; central flower exceeding the bract and visible
3b. Inflorescences swollen and rounded near apex, the terminal with (3–) 5–10 (–14) fertile segments; scarious margin of leaves narrower than 0.3 mm; flowers not exserting stamens, or sometimes, but then after dehiscence; fertile segments widened in the apical portion
