Abstract:
Two species of North American shrubs in the genus Ptelea (Rutaceae), commonly known as eastern and western hoptree or wafer ash, have unfulfilled potential to increase the diversity of managed landscapes and support populations of pollinators and swallowtail butterflies. The white flowers of Ptelea are highly fragrant, and pistillate flowers give rise to clusters of distinctive samaras. The insufficiency of information about improving germination of seeds of Ptelea trifoliata and lack of recommendations for Ptelea crenulata prompted us to investigate effects of pericarp removal and cold (4 °C)

Abstract:
Many members of the citrus family (Rutaceae) are valued for the aromatic compounds emitted by their flowers. Ptelea species are unusually cold-hardy members of the Rutaceae, but conflicting descriptions of the fragrance of their unisexual flowers may discourage the use of these trees. We analyzed floral volatiles and human response to these chemicals to test the hypothesis that the fragrance of staminate and pistillate flowers of these species differs. Gas chromatography and mass spectrometry showed that most volatile chemicals emitted by flowers of Ptelea trifoliata and Ptelea crenulata are m

Abstract:
The bark essential oils of Zanthoxylum clava-herculis and Ptelea trifoliata (Rutaceae) were obtained by hydrodistillation and analyzed by both gas chromatography as well as chiral gas chromatography coupled with mass spectrometry. Z. clava-herculis bark oil was dominated by sabinene [47.0%, 95% (–)-sabinene], limonene [18.7%, 99% (+)-limonene], and terpinen-4-ol [12.9%, 75% (–)-terpinen-4-ol]. The major components in P. trifoliata bark oil were limonene [15.2%, 99% (–)-limonene], sabinene [6.9%, 79% (–)-sabinene], and β-phellandrene [6.2%, 87% (–)-β-phellandrene].

P. trifoliata is a native species of North America (United States of America, northern part of Canada) and has a wide ecological range. However, it prefers fertile, wet soils and moderate light. In Europe, it is planted for its decorative value and is mainly found in synanthropic habitats (parks, graveyards, roadsides, fortifications) in Poland. The station of P. trifoliata is situated in the oak-hornbeam forest, Tilio-Carpinetum typicum, with a sign

Abstract:
In Canada, Ptelea trifoliata L. (Rutaceae) is restricted in its natural distribution primarily to the Lake Erie shoreline. Although it is locally successful as a colonizing species, it appears inhibited from either exploiting a large area of shoreline habitat or extending its range inland. The morphological descriptions of the hop tree's sexual expression have been ambiguous; however, our observations show this species to be clearly dioecious, with only about 2% of the otherwise male plants producing a few hermaphroditic flowers, and fruit. The sex ratio is strongly skewed toward the males, wh
