The extruded pollen-mass is enclosed by a vaulted dome created by apical appendages of the anthers that are lanceolate and inflexed. Pollination appears to be via autogamy ( sensu stricto ) for disk florets and (considering each head as a single blossom) facultative autogamy and allogamy (both geitonogamy and xenogamy) for the ray florets.","PeriodicalId":32630,"journal":{"name":"Oklahoma Native Plant Record","volume":"18 1","pages":"45-51"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68759739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, we quantified the age structure of Fraxinus pennsylvanica Marshall (green ash) at the study site in order to establish a baseline dataset in the event that Agrilus planipennis (emerald ash borer) invades F. pennsylvanica stands in central Oklahoma. Three species, Salix nigra Marshall (black willow), F. pennsylvanica , and Populus deltoides W. Bartram ex Marshall (cottonwood) accounted for over 98% of importance values. These three species were also common in the understory. We found that 95% of F. pennsylvanica established following Arcadia Lake reaching pool conservation status in 1987. Arcadia Lake has experienced five sustained flooding events since 1995 that have likely played a role in regeneration at the study site. In particular, we showed that the 1995 event resulted in reduced radial growth in seedlings of F. pennsylvanica . Two biotic stressors appear to be influencing F. pennsylvanica overstory trees, Castor canadensis (American beaver) and Hylesinus spp. (ash bark beetle), which will likely enhance the establishment of A. planipennis at the study site. We recommend expanding the study of Fraxinus spp. forest stands in Oklahoma. Baseline data on Fraxinus species prior to an A. planipennis range expansion to central Oklahoma can enhance strategies for control and management of this invasive insect by identifying the traits of surviving ash following the invasion.","PeriodicalId":32630,"journal":{"name":"Oklahoma Native Plant Record","volume":"18 1","pages":"4-18"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68758732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An invasive species that has spread throughout much of the southeastern United States, kudzu covers large open areas, overtops forests, and causes significant ecological and economic damage. Oklahoma has seen a relatively minor impact from kudzu, and previous research indicates a limited (less than 0.04 hectare) presence in Tulsa County. We describe a previously undocumented population of kudzu covering over 6.5 hectares in Tulsa County. We determine the age of this population and its rate of expansion. Documenting and mitigating kudzu populations will likely become increasingly important to protect Oklahoma’s native biodiversity.","PeriodicalId":32630,"journal":{"name":"Oklahoma Native Plant Record","volume":"18 1","pages":"19-23"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68759858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eastern redcedar ( Juniperus virginiana L.) is a native but invasive conifer that is rapidly expanding its range in Oklahoma due to human and ecological factors and the ability to tolerate aridity. It is known to reduce soil moisture due to high rates of water uptake compared to neighboring grasses and herbaceous species. The objectives of this study were to compare average amounts of water transpired between eastern redcedar and adjacent woody trees in central Oklahoma to determine how water loss in the conifer compares with other trees in the same locality. Average amounts of transpiration in eastern redcedar were compared with those of loblolly pine ( Pinus taeda L.) , white mulberry ( Morus alba L.) , eastern cottonwood ( Populus deltoides W. Bartram ex Marshall) and bur oak ( Quercus macrocarpa Michx.). Three to six branch tips per tree were securely bagged over 24-hour periods, and water collected in each bag was weighed and analyzed. Three to five sampling months spanning two or three seasons were conducted for each comparative study. Results indicated that for winter, spring, and fall, transpiration from eastern redcedar exceeded that from the other tree species. Weather variables such as day length and temperature were found to have strong to moderate effects on transpiration in eastern redcedar. Day length and temperature also had strong effects on transpiration in white mulberry and bur oak, respectively, and humidity had an effect on transpiration in loblolly pine. No reliable or significant effect of weather variables was detected in eastern cottonwood.","PeriodicalId":32630,"journal":{"name":"Oklahoma Native Plant Record","volume":"59 1","pages":"24-37"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68760133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
