New records, distribution and taxonomic notes for non-native vascular flora of Tunisia – I. Poaceae

Abstract

printed, 2240-4538 online. Six new taxa of the Poaceae family are added to the non-native flora of Tunisia: Cenchrus longisetus M. C. Johnst., Digitaria ciliaris (Retz.) Koeler, Eleusine indica (L.) Gaertn., Eragrostis cilianensis subsp. thyrsiflora (Willk.) H. Scholz & Valdés, Eragrostis pilosa (L.) P. Beauv. and Paspalum dilatatum Poir. Five of them are considered naturalized and horticultural trade is considered the most likely pathway for their introduction, whereas Eragrostis pilosa (L.) P. Beauv., might have been introduced as impurity in cereals for field crops. Populations of Tunisian E. pilosa are characteristic in possessing glandular pits, especially on inflorescence branches, a character not observed in E. pilosa s. str. in Europe and the Mediterranean area. Actual distribution and taxonomic notes are also given for all newly reported reported taxa.

Bassia scoparia (Amaranthaceae s. l.) and Sesuvium portulacastrum (Aizoaceae), two new naturalized aliens to the Tunisian flora

“…2017, Domina & El Mokni 2019El Mokni & al. 2015, 2019 but also the discover of many species new for the non-native Tunisian flora (see e.g., Iamonico & El Mokni 2016;El Mokni & Domina 2017a;El Mokni & Domina 2017b;Iamonico & El Mokni 2017a, 2017b, 2018El Mokni & Domina 2018;El Mokni & Verloove 2019;Iamonico & El Mokni 2019a, 2019b. In this paper, we provide further results related to the families Aizoaceae Martinov and Amaranthaceae Juss.…”

First appointment of the invasive Cyperus eragrostis (Cyperaceae) as an established species in Tunisia

“…(see e.g. El Mokni 2018a, 2018bEl Mokni & Domina 2018a, 2018bEl Mokni & Verloove 2017, 2019a, 2019bEl Mokni & Hadj Khalifa 2020), field surveys revealed a naturalized population of C. eragrostis, thus representing its first record in Tunisia. Given the species' invasive attributes, this likely will be the precursor of a wider naturalization in the area.…”
