| Seringia botak Cheek sp. nov., based on a collection made by the authors in 2017, is described from metalliferous grassland and savannah habitats in Indonesian New Guinea. Initially this appeared to be the first verified record of Seringia from SE Asia and to extend the range of the genus c. 1500 km further north than the previously recorded northern limit in Northern Territory, Australia. Further research, however, showed two previous specimens of the taxon from New Guinea, which had been overlooked. The extinction risk of Seringia botak is assessed as Endangered using the IUCN 2016 standard. |

| ABSTRACT: Seed longevity under different environmental conditions is considered as one of the most important factors in the spread and persistence of an exotic species. The Experiments were conducted to determine seed persistence in soil, effects of submergence in water, flooding of the soil, and high temperatures on germination and viability of spotted spurge (Chamaesyce maculata) and wild poinsettia (Euphorbia heterophylla) as two exotic species in different regions of Golestan province. Spotted spurge seeds buried at depth of 10 cm maintained their viability above 95% after a year, while wild poinsettia seeds were destroyed completely after exhuming the soil. Seeds of both species were unable to germinate under submergence, but 92% of the spotted spurge... |
