This is a perennial or annual succulent that grows up to 35 cm (Western 1992, Jongbloed et al. 2003). It produces purple flowers between February and May, in addition to characteristic pickle-shaped fruit, and grows among rocks, gravel plains, wadis and mountains (Jongbloed et al. 2003, Feulner 2016). When the plant is damaged, it secretes milky sap (latex) which is characteristic of Asciepiadaceae species (Western 1992). The species is considered to be a xerohalophyte i.e. a salt-tolerant desert species (Böer and Saenger 2006).

Assessment rationale/justification
This species is considered to be rare within its range and is often grazed to the point of visibly stunted growth. This may pose a significant threat to the species, however the full extent of this is still unclear. Although the species occurs in a National Park, it is important to draw attention to this potentially threatened and rare species. As a result, it is cautiously assessed as Vulnerable (D1) as a result of the small number of mature individuals, which is suspected to be close to or less than 1,000, but no reliable count has been made. It also has a restricted distribution (estimated EOO: 6,378 km<sup>2</sup>). The species occurs in adjacent parts of Oman and the seed is wind-dispersed, therefore the assessment is revised down by one category to Near Threatened.

Assessment rationale/justification
This species has a fairly restricted distribution within the UAE and is considered to be rare, even within its range. The estimated EOO and of this species is 261 km<sup>2</sup> which falls within the threshold for threatened categories. Based on this restricted distribution and the possibility of collection from the wild for cultivation, in addition to the rarity of the species, the species is assessed as Endangered, with the number of mature individuals suspected to be fewer than 250. No rescue effect is likely, with the nearest populations some distance away in Oman.

This is a perennial shrub that grows up to 80 cm (Reza Khan 1992). It flowers throughout the year but peaks between January and May (Jongbloed et al. 2003). It is a poisonous plant that grows in gravel and sand plains as well as wadis (Drew 2000, Jongbloed et al. 2003, Mahmoud et al. 2018). Its presence is known to be a sign of overgrazing as livestock avoid eating it, and so it becomes dominant in grazed areas (Feulner 2011, 2016). However, the flowers of this plant are known to be utilised by adult Plain Tiger butterflies (Gillett 1998).

Much of the published literature on Tamarix passerionoides refers to this species under the synonym, Tamarix aucheriana. In order to accurately assess this species, it's important to determine whether these plants are indeed two distinct species and, if so, determine a detailed distribution for T. passerionoides under its own name to effectively assess its risk of extinction in the UAE. For now, it is assessed as Data Deficient pending further research into its taxonomy.
