The species is widespread on sand, gravel, along roadsides in urban areas, and in the Hajar Mountains (Jongbloed et al. 2003, M. Jongbloed pers. comm. 2019). It is also found in arable areas and plantations (Karim and Dakheel 2006), in addition to towns (G. Feulner pers. comm. 2019).

The species is found in plantations and is generally peri-agricultural (G.R. Feulner pers. comm. 2019).

This annual species has slender stems and can reach up to 0.5 m in height (Jongbloed et al. 2003). It climbs on surrounding vegetation and has downward pointing prickles on both the spines and the leaf whorls, which give the plant a 'sticky' feel (Jongbloed et al. 2003). The fruit is a round, hairy capsule and the small white flowers can be seen between February and April (Jongbloed et al. 2003). It generally grows within mountain wadis and in plantations (Jongbloed et al. 2003). G.R. Feulner (in litt, MEW 2010) notes that it is found in the same habitats as G. ceratopodum, in the foothills and wadis, on silty soils amongst stones and near water channels and runnels.

This annual herb species is known to grow in mountain environments and hillsides, in addition to within wadis and on wadi slopes (Jongbloed et al. 2003, Feulner 2014, 2016, Mahmoud et al. 2018). It can grow up to 15 cm tall, has branches covered in soft hairs, leaves with pointed tips and produces small yellow-white flowers which can be seen between February and April (Jongbloed et al. 2003).

Nerium oleander is reported to be associated with areas comprising wet sand, standing water and along the margins of shall water bodies (Rothfels et al. 2012, Patzelt 2015). Despite its affinity for water, it is also a halophyte and is frequently found in salty habitats (Karim and Dakheel 2006). It is has been found growing within deep, canyon-like wadis at low altitudes (Patzelt 2015) and is generally considered to be a characteristic species of wadis (El-Keblawy et al. 2016). This dense evergreen shrub species is considered to be poisonous which causes goats, and other browsers, to ignore this plant (Ghazanfar and Fisher 1998, Karim and Dakheel 2006, El-Keblawy et al. 2016). It has woody stems, can grow to heights of 1-4 m and produces large pink flowers between September and March (Jongbloed et al. 2003, Karim and Dakheel 2006).

This is an annual species that can grow up to 40 cm in height (Jongbloed et al. 2003). It has basal rosette leaves in addition to upper leaves, alongside small white flowers which are produced between February and April (Jongbloed et al. 2003). It can typically be found growing in sandy soil found within moist and irrigated places including plantations and gardens (Jongbloed et al. 2003, MEW 2010).

This annual herb species can be found growing in old and fallow fields, in addition to cultivated areas, wadis and gravel terraces (Western 1991, Norton et al. 2009, Feulner 2011). The plant can grow up to 60 cm in height and produces white 'hair-like' flowers between February and April (Jongbloed et al. 2003). It is utilised as a food plant by the butterfly, Papilio machaon (Jongbloed et al. 2003).

The species is widespread in sandy deserts and lower hills (MEW 2010). Feulner (2016) recorded the species from shaded north-facing rubble slopes in Wadi Wurayah, where it is normally a climber or straggler, rarely a shrub. Often found climbing Prosopis cineraria ghaf (Jongbloed et al. 2003) and Acacia trees.

This is a small perennial shrub, up to 1 m in height (Jongbloed et al. 2003). It is found on rocky flats.

The species is found on bedrock wadi banks and coarse gravel wadi beds, particularly near areas with permanent or intermittent surface water pools from 200 m to 700 m asl. The species has also been recorded from plantations in the Hajar Mountains. It is a small and elusive diurnal species, which upon detection of a potential threat will rapidly retreat into rock cracks and crevices. Combined with its small size, long flight distance and the rocky habitat it occupies, the species is often under-sampled during surveys. It is active throughout the year, although during the summer months, activity is limited to the early mornings and late afternoons. They appear to be predominantly solitary, with pairing observed during the cooler months from October to May. Females lay several clutches of two to three large eggs measuring 9 by 4 mm (Gardner 2013). Hatchling measured 25 mm snout to tail length with a tail length of 55 mm (Gardner 2013).
