It produces flesh-coloured flowers with dark stripes in addition to constricted seed pods (Jongbloed et al. 2003). It is also considered to be a xerohalophyte (desert-growing salt-tolerant species) that is often found growing at the top of rocky hills within sand desert (Böer and Saenger 2006).

This herb species grows in fallow fields and hillsides within montane areas (Jongbloed et al. 2003, Norton et al. 2009, MEW 2010). It has an annual life cycle, grows up to 0.2 m in height and produces yellow stalks between February and April (Jongbloed et al. 2003).

Hippocrepis constricta grows in sand and gravel plains in addition to hillsides at low altitudes (Jongbloed et al. 2003). It is an annual herb species which can grow up to 30 cm in height and produces pale yellow/white flowers between February and April (Jongbloed et al. 2003, Mahmoud et al. 2018).

This herb species grows in sand and gravel environments, such as sandy deserts and lower montane habitats (Jongbloed et al. 2003, Norton et al. 2009, Mahmoud et al. 2018). It has an annual life cycle and produces groups of bright yellow flowers between February and May (Jongbloed et al. 2003).

Within the Wadi Wurayah National Park, it is generally found growing on gentle wadi banks (Feulner 2016). The plant grows to between 90-100 cm in height and flowers between February and April (Jongbloed et al. 2003, Karim and Dakheel 2006). It is a moderately salt-tolerant species (Karim and Dakheel 2006). Crotalaria aegyptiaca is a crop wild relative of sunhemp, Crotalaria juncea (Kameswara Rao 2010).

This annual herb species grows within compacted sand (Jongbloed et al. 2003, Mahmoud et al. 2018). It has prostrate stems that reach lengths of up to 30 cm, lance-shaped leaves, white flower clusters between February and April and star-shaped, hairy seed pods (Jongbloed et al. 2003).
