The numbers of disk floret anthers of Calyptocarpus vialis in Wichita County, Texas form a consecutive series of one to four; four anthers (71%) and three anthers (27%) were most common. Three anthers is an unusual, perhaps singular, number for Asteraceae. These florets also have four-lobed corollas. 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.

We characterized the structure and tree species composition of bottomland hardwood forest at Arcadia Lake, Oklahoma County, Oklahoma. 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.
研究了俄克拉何马州阿卡迪亚湖湖底阔叶林的结构和树种组成。此外，我们量化了研究地点的宾夕法尼亚白蜡螟(green ash)的年龄结构，以便在俄克拉荷马州中部的宾夕法尼亚白蜡螟(Agrilus planipennis)入侵的情况下建立基线数据集。柳(Salix nigra Marshall)、F. pennsylvania和杨树(Populus deltoides W. Bartram ex Marshall)占重要值的98%以上。这三种植物在林下也很常见。在1987年阿卡迪亚湖(Arcadia Lake)达到池塘保护状态后，95%的宾夕法尼亚白桫椤(F. pennsylvania)在此定居。自1995年以来，阿卡迪亚湖经历了五次持续的洪水事件，这可能在研究地点的再生中发挥了作用。我们特别指出，1995年的事件导致了宾夕法尼亚赤杨幼苗径向生长的降低。两种生物压力源似乎影响了F. pennsylvania林下树木Castor canadensis(美洲海狸)和Hylesinus spp.(灰树皮甲虫)，这可能会促进A. planipennis在研究地点的建立。我们建议扩大对俄克拉何马州白蜡属林分的研究。在planipennis范围扩展到俄克拉荷马州中部之前的基线数据可以通过确定入侵后幸存灰烬的特征来加强控制和管理这种入侵昆虫的策略。

Pueraria montana (Lour.) Merr. var. lobata (Willd.) Maesen & S.M. Almeida ex Sanjappa & Predeep (Fabaceae; kudzu) is a deciduous perennial vine native to China. 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.

Myriopteris lindheimeri (Hook.) J. Sm. (fairy swords; Pteridaceae) is an apogamous fern of the southwestern United States. Fairy swords are native to Arizona, New Mexico, Texas, and Oklahoma. The only two records in Oklahoma are from Comanche County: F.B. McMurry in 1942 and J.B. Beck with C.J. Rothfels in 2017. In this article, I report a new sighting from Kiowa County, describe the species, and explain how it can be distinguished from other southwestern Oklahoma species in the genus.

Fire suppression and grazing on the Great Plains have resulted in alteration of the grassland ecosystem, including an increase in woody trees. 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.
大平原上的灭火和放牧导致了草原生态系统的改变，包括木本树木的增加。东部红杉(Juniperus virginia L.)是一种本土入侵针叶树，由于人类和生态因素以及对干旱的耐受能力，它在俄克拉荷马州迅速扩大了其范围。众所周知，与邻近的禾草和草本物种相比，由于吸水率高，它可以减少土壤水分。本研究的目的是比较俄克拉何马州中部东部红杉和邻近木本树木之间的平均蒸发量，以确定针叶树与同一地区其他树木的失水情况。比较了东部红杉与火炬松(Pinus taeda L.)、白桑(Morus alba L.)、东部白杨(Populus deltoides W. Bartram ex Marshall)和黑栎(Quercus macrocarpa micx .)的平均蒸腾量。在24小时的时间里，每棵树的三到六个枝尖被安全地装上袋子，每个袋子里收集的水被称重和分析。每个比较研究进行三到五个采样月，跨越两到三个季节。结果表明:冬、春、秋三季，东红杉蒸腾量均大于其他树种;发现昼长和温度等天气变量对东部红杉的蒸腾作用有强烈到中等的影响。白天长度和温度对白桑和黑栎的蒸腾作用也有较大影响，湿度对火炬松的蒸腾作用有较大影响。在东部棉杨中没有发现可靠的或显著的天气变量影响。
