INTRODUCTION (Cholistan and Thar) and arid regions where the rainfall African purslane (Zaleya pentandra, family Aizoaceae), is is extremely low. Regardless of the extreme conditions, an important annual weed in arid and semiarid regions of this plant shows vigorous growth with strong root system the world. Native to Africa, it prevails in most of the binding soil particles thus making way for its potentiality regions in the world (Hyde et al., 2018) while exists as an as an erosion control plant. The vigorous information invasive weed species in Arab, Zambia, Pakistan presented on this plant makes way for further studies (Mahmood et al., 2012) and India (Suthari et al., 2011). It related to phytochemical and pharmacological belongs to the genus Trianthema which consists of 20 standardization of extracts, separation, and recognition species, but a few of them are reported as potential of vigorous constituents, pharmacological studies and the important ones for their use either as fodder or erosion mode of action, formulation development, toxicological controlling plants (Geethalakshmi et al., 2010). In and therapeutic efficiency. Pakistan Z. pentandra prevails in the desert areas Z. pentandra currently possesses the status of a desert 137 Plant Protection, 02 (03) 2018. 137-143 weed, but allied to its utilization as a fodder and genera spread in the tropics and sub-tropics of South medicinal plant, this species can be utilized effectively in Africa (Mabberley, 2008). Six species were reported controlling health, feed for livestock and land from Australia, Africa, and Asia. From Pakistan, Z. conservation in arid regions where all resources are pentandra is the only reported species (Kanwal et al., always limited. This paper demonstrates and reviews the 2009). existing information on inventive questions of interest on Synonyms and common names: Z. pentandra is weeds. With the advent of resource conservation recognized with different names specific to the region of methods, researchers are making efforts to conserve dry occurrence. Its synonimical names are Rocamaprostrate land areas which are highly prone to erosion and for this Forssk, Rocama Arabica, Trianthemia digyna DC and purpose, Z. pentandra can serve as a blessing. By keeping Trianthema govindia. While heterotypic nomenclature of in view these needs, valuable information is gathered and Z. pentandra includes Limeum keniense, Trianthema presented to assist scientists for future pentandra var hirtulum. African purslane has a recommendations. Homophytic name as Trianthema (Hassler, 2014; Hepper Taxonomy: Zaleya pentandra belongs to the family and Friis, 1994). The common names of Z. pentandra in Aizoaceae (Munawar et al., 2015) consisting of 127 different regions are listed in Table 1. Table 1: Common names of Z. pentandra.

Now effectively in arid regions open new gates in research. Figure 1.Worldwide distribution of Zaleya pentandra. Habitat, climate and soil: Z. pentandra grows in a large The petioles are short compared to the blades and form variety of climates and soils. It is a weed of gravelly and scarious wings sheathings (Alfarhan et al., 2005). Flowers sandy soils. It is found along roadsides and marginal are very minute forming a cluster at axial. They are sessile lands. Z. pentandra is reported to be very common in and subsessile and lack corolla. Two styles with a red woodlands, high saline and desert areas (Muhaidat et al., capsule, five stamens and perianth lobes are present. 2007; Norton et al., 2009). Owing to its hardy nature and Colour of flowers varies in the shades of pink. Four black large scale spread in arid lands, Z. pentandra may also be seeds are encapsulated in jelly-like red color fruit. Aril is referred to as a drought tolerant plant species which is absent in shiny black seed, which is elliptic in shape with found at an elevation of 1600 m from sea level (Jeffery, a sub-central hilum. Its seed size varies from 1.6 to 1.8 1960). It is adapted to a wide variety of ecological zones mm and testa is Aerolate, and rugose. Its seed does not which categorize it as xerophytic, terrestrial plant, contain any aril (Kanwal et al., 2009).while its pollen neutrophils plant, sciophytic, phreatophytic, lithophytic, morphological description is shown in table 2. mesophytic, halophytic, therophytic and acidifuge plant Anatomy: Z. pentandra is a eudicot which has a double (Ehsen et al., 2016).
