Abstract
Recent field and herbarium studies have revealed the presence of 57 species, two varieties, and three hybrids of vascular plants and one moss not previously published with verification from Nebraska. Twenty-eight taxonomic entities are considered likely native in Nebraska, including: xAchnella caduca, Arabis divaricarpa, Aster ascendens, Atriplex suckleyi, Callitriche heterophylla, Campylium stellatum, Carex hirtifolia, Carex lasiocarpa var. americana, Chenopodium cycloides, C. pallescens, Dioscorea quaternata, Draba brachycarpa, Eleocharis wolfii, Elatine brachysperma, Elodea bifoliata, xElyhordeum iowense, xElyhordeum montanense, Eragrostis secundiflorus ssp. oxylepis, Erigeron lonchophyllus, Houstonia pusilla, Maianthemum canadense, Mirabilis exaltata, Myosotis verna, Pedicularis crenulata, Plantago rhodosperma, Potentilla simplex, Scutellaria parvula var. parvula, and Stachys hispida. Of the remaining 35 species and varieties, seven are indigenous to North America and seem to have entered the state along roadsides in recent years (Achnatherum robustum, Amaranthus powellii, Anemopsis californica, Argemone hispida, Bouteloua simplex, Solanum elaeagnifolium, and Sphaeralcea cuspidata var. angustifolia), while the remaining 27 represent Eurasian or tropical American introductions. Of these, eight species (Allium vineale, Centaurea maculosa, Digitalis lanata, Elaeagnus umbellata, Lonicera maackii, Myriophyllum spicatum, Pueraria lobata, and Rhamnus frangula) are serious pests outside Nebraska.
