The study was conducted to evaluate the efficiency of big-sage (Lantana camara) plant in the phytoremediation of Cd, Co, and Pb heavy metals added at 0.0, 0.2, 0.4, 0.6, and 0.8 mg L-1 concentration for each of them to in vitro culture medium. The results showed a significant increase in cadmium and cobalt levels in the vegetative parts and root of big-sage plantlets by increasing their culture medium concentrations. The plantlets supplied with 0.8 mg L-1 of Cd and Co were significantly superior compared to 0.2, 0.4, and 0.6 mg L-1 Cd and Co in terms of Cd and Co accumulation, which reached 0.192 and 0.318 mg kg-1 Cd and 0.326 and 0.312 mg kg-1 Co in vegetative and root parts, respectively. On the other hand, it was noticed that Pb did not accumulate in the vegetative parts when added to the culture medium. Furthermore, results showed that adding 0.8 mg L-1 Cd and Co resulted in higher bioconcentration of heavy metals with values 0.32 and 0.4 for both metals, respectively. The highest translocation factor for cadmium (0.67) and cobalt (4.23) was recorded under 0.6 mg L-1 cadmium and 0.2 mg L-1 cobalt. The results of the current study are encouraging to investigate in situ phytoremediation potentials of big-sage plant in heavy metal polluted soils.

This paper documents the presence of the invasive aquatic fern Azolla filiculoides (Salvinaceae) in the White Nile near Al Hideib village in Sudan. Morphological characters of vegetative and male reproductive parts were investigated. Primary and secondary rhizomes arrangements, roots positions and numbers, color and surface hairs of the submerged and floating leaves, leaf arrangements and margin, in addition to shape and size of male sporocarps and sporangia were reported as key characters. Habitat description and complementary notes were also provided.
