This species is an annual which flowers from February to April and produced a triangular yellow nutlet for a seed (Ghazanfar and Fisher 1998, Jongbloed et al. 2003). It grows up to 0.25 m in height with lance-shaped leaves (Jongbloed et al. 2003). It is an important contributor to biomass in the dune and stabilised sand environment which it inhabits (Ghazanfar and Fisher 1998, Jongbloed et al. 2003). Rumex pictus is a crop wild relative of sorrel, Rumex acetosa (Kameswara Rao 2013).

This annual species has purple flowers and is described as growing within damp soil in shaded habitats, in addition to within fallow fields.

This is a perennial shrublet species that grows within sandy depressions, wadis and along roadsides (Jongbloed et al. 2003, Karim and Dakheel 2006, Mahmoud et al. 2018). This species can reach up to 60 cm in height, has trifoliate leaves, small yellow flowers between March and July in addition to long woolly seed pods (Karim and Dakheel 2006). It is moderately salt-tolerant (Karim and Dakheel 2006).

This is an annual or perennial herb to 0.3 m in height that is found on gravel plains and in the mountains (Jongbloed et al. 2003).

This species is a perennial branched plant that is found on hillsides, on silt amongst rocks (Jongbloed et al. 2003, Feulner 2011). Feulner (2014) suggests that the species may be dependent on carbonate rock.

It can be found growing in savannah-like plain habitats consisting of sandy hummocks (Wardman et al. 1997), in addition to gravel plains (Mahmoud et al. 2018) and nearby hillsides or mountains (Western 1991). The perennial species grows as a small shrub, reaching up to 30 cm in height (Western 1991, Fawsi and Ksiksi 2012, Mahmoud et al. 2018). It has woody stems which yellow flowers on stalks present between February and June (Jongbloed et al. 2003).

This is a small, perennial shrub species which can be found growing on hillsides (Fawzi and Ksiksi 2012, Mahmoud et al. 2018). The species can grow up to 30 cm in height and has narrow green-silver leaves, in addition to yellow flower-heads which are present between February and April (Jongbloed et al. 2003).

This shrub species is perennial, producing flowers from February to April (Western 1991, Jongbloed et al. 2003). It has cylindrical, worm-like leaves and small fruits with papery wings (Jongbloed et al. 2003, Feulner 2016). The stems branch several times; the plant itself grows up to 150 cm in height (Jongbloed et al. 2003). It is found in terrace habitats (highly disturbed habitats) within Wadi Wurayah National Park (Judas 2016), in addition to wide wadi beds, rocky wadi slopes and gravel plains (Perry 2008). It is known to favour ultrabasic bedrock environments (Ghazanfar and Fisher 1998, Feulner 2016).

Pterocephalus brevis is found in the mountains to at least 1,500 m asl and on gravel plains (Jongbloed et al. 2000, Feulner 2011).

The trees can reach up to 10 m in height and are known to grow in sand dunes and plains in addition to more rocky wadi habitats (Gallacher and Hill 2005, Karim and Dakheel 2006, Mahmoud et al. 2018). In terms of growth form, this species grows from a woody shrub to a plant covered in thorns - this then allows the plant to resist grazing so that it can grow into an adult tree (Gallacher and Hill 2005). It has oblong leaves with pointed tips, in addition to solitary or twin flowers which can be seen between March to May and October to January (Jongbloed et al. 2003, Gallacher and Hill 2005, Karim and Dakheel 2006). Prosopis cineraria has also been described as a salt-tolerant and leguminous tree (Karim and Dakheel 2006). Regeneration of this perennial tree species is limited which may have knock on effects in terms of the overall population trend in the UAE (Gallacher and Hill 2005, Fawzi and Ksiksi 2012).
