Checklist of Wadi Hassan flora, Northeastern Badia, Jordan.

ABSTRACT: In this study, we survey the plant diversity of Wadi Hassan, which is located in the Northeastern Badia of Jordan, about 120 km east of Amman. All plant species were collected and herbarium specimens have been prepared, identified and deposited at the University of Jordan herbarium (Department of Biology, Faculty of Science). The final plant checklist includes 206 species belonging to 138 genera and 35 families. The most diverse families are Compositae (20.5%), Cruciferae (10.2%), Leguminosae (8.3%) and Boraginaceae (6.8%), followed by Caryophyllaceae and Gramineae (5.4%). These six families represent 60% of the total families recognized in the study area, while nine families each are represented by only one species. Most plants recorded are annual plants (61%), some plants are hemicryptophtes (18%) and camaephytes (15%), while the least frequent life form class was the phanerophyte shrub and perennial (0.5%). Chorological characteristics of the recorded flora show that Saharo-Arabian Region elements, Irano-Turanian elements and Mediterranean elements constitute (58%) of the total flora. This research shows that even small portion of the Jordan Badia such as the Wadi Hassan plant community has high species diversity. Thus, we recommended further of the unexplored Wadi plants communities of the Jordan Badia.

Project description:The Coppermine River in western Nunavut is one of Canada's great Arctic rivers, yet its vascular plant flora is poorly known. Here, we report the results of a floristic inventory of the lower Coppermine River valley and vicinity, including Kugluk (Bloody Falls) Territorial Park and the hamlet of Kugluktuk. The study area is approximately 1,200 km2, extending from the forest-tundra south of the treeline to the Arctic coast. Vascular plant floristic data are based on a review of all previous collections from the area and more than 1,200 new collections made in 2014. Results are presented in an annotated checklist, including citation of all specimens examined, comments on taxonomy and distribution, and photographs for a subset of taxa. The vascular plant flora comprises 300 species (311 taxa), a 36.6% increase from the 190 species documented by previous collections made in the area over the last century, and is considerably more diverse than other local floras on mainland Nunavut. We document 207 taxa for Kugluk (Bloody Falls) Territorial Park, an important protected area for plants on mainland Nunavut. A total of 190 taxa are newly recorded for the study area. Of these, 14 taxa (13 species and one additional variety) are newly recorded for Nunavut (Allium schoenoprasum, Carex capitata, Draba lonchocarpa, Eremogone capillaris subsp. capillaris, Sabulina elegans, Eleocharis quinqueflora, Epilobium cf. anagallidifolium, Botrychium neolunaria, Botrychium tunux, Festuca altaica, Polygonum aviculare, Salix ovalifolia var. arctolitoralis, Salix ovalifolia var. ovalifolia and Stuckenia pectinata), seven species are newly recorded for mainland Nunavut (Carex gynocrates, Carex livida, Cryptogramma stelleri, Draba simmonsii, Festuca viviparoidea subsp. viviparoidea, Juncus alpinoarticulatus subsp. americanus and Salix pseudomyrsinites) and 56 range extensions are reported. The psbA-trnH and rbcL DNA sequence data were used to help identify the three Botrychium taxa recorded in the study area. Three new combinations are proposed: Petasites frigidus subsp. sagittatus (Banks ex Pursh) Saarela, Carex petricosa subsp. misandroides (Fernald) Saarela and Carex simpliciuscula subsp. subholarctica (T. V. Egorova) Saarela.
