Titre : Pennisetum setaceum or Pennisetum advena cultivars, what ornamental do we have in our garden Type de document : Imprimé Auteurs : Johannes Leonardus Cornelis Hendrikus van Valkenburg (1964) ; Maarten Costerus ; Marcel Westenberg Année de publication : 2021 Article en page(s) : 11216-11222 Langues : Anglais (eng) Mots-clés : Cenchrus Pennisetum setaceum (Forssk.) Chiov., 1923 Pennisetum advena Résumé : Pennisetum Rich. or following recent taxonomic insights Cenchrus L. is a genus with some 120 species worldwide, especially in warm areas. The genus includes some crops, some ornamentals but mostly species that are considered weedy. The name of one of the weedy species Pennisetum setaceum (Forssk.) Chiov. is also found on labels of ornamental grasses as P. setaceum “Rubrum.” It has been debated to belong to a species on its own Pennisetum advena Wipff & Veldkamp or Cenchrus advena (Wipff & Veldkamp) Morrone, only known from cultivation, whereas others still adhere to a broader species concept of P. setaceum. The recent inclusion of P. setaceum on the EU List of Union concern has revitalized the discussion on this issue for commercial reasons. Based on a morphological and molecular comparison (ITS, rbcL, and the trnh-psbA intergenic spacer sequences) of the type specimen of P. advena, five of its “cultivars” in trade and collections of P. setaceum from different regions of the world we conclude that plants currently in trade in Western Europe belong to a separate species P. advena. A drooping inflorescence is consistent as is the difference in width of the leaf blade, the leaf blade being flat or involute, the central vein being swollen or not, and the length of the stipe being 0.3–1.1 mm in P. advena and 1.1–3.1 mm in P. setaceum. On the chloroplast markers rbcL and trnH-psbA, the species consistently differ in 2 and 4 base pairs, respectively. On the nuclear ITS sequence, there is only 90% overlap between the two species. This justifies these ornamentals to be

Titre : Comparing common fountain grass removal techniques: cost efficacy and response of native plant community Type de document : Imprimé Auteurs : Helen I. Rowe ; Tiffany A. Sprague ; Paul Staker Année de publication : 2022 Article en page(s) : 3817-3830 Langues : Français (fre) Catégories : [CBNPMP-Thèmes] Plantes subspontanées, naturalisées, envahissantes Mots-clés : Pennisetum setaceum (Forssk.) Chiov., 1923 Résumé : Fountain grass (Pennisetum setaceum) is a globally pervasive invasive species and a prime example of an escaped horticultural ornamental. In areas where it is not naturally found, it displaces native plant communities and disrupts ecological systems and processes. Cost-effective removal efforts that protect the native plant community are needed for its control. We conducted an experiment from March 2018 to March 2021 in 5 m × 5 m plots to test the efficacy and record costs for common removal techniques (cut and herbicide, herbicide one or two times per year, manual removal) in the Sonoran Desert, Arizona, United States. Each treatment took 2.5 years to achieve control in the plots, and treatments did not negatively affect the native plant community. The response of native plants was mediated by year, such that native cover in treatment plots recovered to similar levels as uninvaded control plots with sufficient rainfall. Plots that received the manual removal treatment had almost five more native plant species than the invaded control treatment (22.7 ± 1.63 compared to 18.1 ± 1.61). Herbicide applied in spring and fall increased efficacy of removals in the first year but was not significantly different from the other treatments averaged over year. Herbicide once per year was most cost effective across different sized areas. Manual removal was also cost effective in small areas (< 0.06 hectares) but was more expensive than herbicide twice a year in larger areas. Our results provide a toolset that enables managers to select removal treatments based on a balance of convenience, resources, and scale of the infestation.
