Plant list, 2020 suggest that it is asynonymous with Satica camosa Boiss.

It is often covered in salt crystals, has narrow spoon-shaped leaves and pale-pink or white flowers which are seen between March and May (Jongbloed et al. 2003). Limonium carnosum is generally found growing in saline sand and silt within gravel plain environments (Jongbloed et al. 2003), although it also utilises rocky environments.

Assessment status criteria
B1ab(iii)
Assessment rationale/justification
This species occurs in severely fragmented localities across the UAE. The estimated extent of occurrence (EOO) of its range is 493 km<sup>2</sup>, which falls within the threshold for Endangered under Criterion B1. In addition, this species is considered to occur at three threat-based locations and is experiencing ongoing decline in the extent and quality of habitat due to development of buildings, roads and infrastructure. Therefore, this species is assessed as Endangered B1ab(iii).
