Copaifera belongs to the Detarieae (Detarioideae) and is part of a clade together with five other genera. We describe the seedling morphology of Copaifera pubiflora Benth. based on plant architectural analysis to shed light on its post-seminal shoot development. Seeds of this species were collected from a wild population in Roraima State, Brazil. Seedlings of C. pubiflora have preformed shoots with determinate and rhythmic growth. Each growth unit has two reduced leaf scales that correspond to a pair of prophylls followed by two or three scale-like stipules and one distal eophyll. Besides, C. pubiflora has a monochasial sympodial branching with delayed branches. Current evidence indicates that most Copaifera species, including C. pubiflora, have phanerocotylar, epigeal, reserve seedlings with a cataphyll-free epicotyl and scale-like structures on the first internode after the epicotyledonary axis. Based on the available data, a comprehensive view of Copaifera seedlings from both the Old and New Worlds is also presented.","PeriodicalId":53662,"journal":{"name":"Feddes Repertorium","volume":"133 4","pages":"313-321"},"PeriodicalIF":0.0,"publicationDate":"2022-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41958618","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}

Duckweed samples were taken from eight localities in the northern regions of Ukraine and identified to species using morphological and molecular markers (barcoding). A new alien species of duckweed for Ukraine—lesser duckweed (Lemna aequinoctialis Welw.)—was discovered, to which this study is devoted. All other samples belonged to Lemna minor. The article presents the most complete description of the distribution of L. aequinoctialis Welw. in Europe, and also contains updated data on the species distribution of duckweeds in Ukraine. Six species of the genus Lemna are now known in Ukraine—three native and three alien. The ecological requirements of L. aequinoctialis are similar to those of L. minor. We examined the morphological similarities and differences between these species, and confirmed the results by molecular barcoding using the plastid regions of the atpF-atpH and psbK-psbI intergenic spacers.","PeriodicalId":53662,"journal":{"name":"Feddes Repertorium","volume":"133 4","pages":"305-312"},"PeriodicalIF":0.0,"publicationDate":"2022-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fedr.202200001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44766406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, the present study examined the degree and trends of chromosome diversity in this genus in congruence with Kupicha's sectional classification. Karyo-morphological data for 74 species representing 11 sections of Lathyrus were collected through the literature survey. The karyological measures included were the total haploid chromosome length (THL), somatic chromosome number (2n), basic chromosome number (x), and five other parameters of karyotype asymmetry (CVCL, CVCI, MCA, A1, and A2). Basic chromosome number (x = 7) and somatic chromosome number (2n = 14) remained stable throughout the genus. Mean karyotypes revealed marked variations in karyotype structure among the 11 sections of Lathyrus. Further, key differences were identified during comparisons of various measures of karyotype asymmetry. Phylogenetic and principal coordinate analyses exhibited substantial variation among different sections of Lathyrus and out-group genera. Overall, current findings indicated that the karyotype asymmetry measures can serve as an efficient tool to assess the relationship among different sections of Lathyrus.","PeriodicalId":53662,"journal":{"name":"Feddes Repertorium","volume":"133 3","pages":"199-214"},"PeriodicalIF":0.0,"publicationDate":"2022-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41419843","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}

For this, we collected environmental and biophysical data and sampled the regeneration of tree/shrubby species in 30 plots in two different veredas. The moisture and chemical characteristics of the soil, and regeneration composition were similar among the vereda zones, but showed important variations among sample units. In addition to soil moisture, soil chemical elements and canopy coverage characteristics also formed environmental gradients. The native tree/shrubby species occupied different positions along the environmental gradient of the veredas. The invasive species P. caribaea was more concentrated in less declined sites, in more basic and more humid soils, together with most native species. In general, the results demonstrate the absence of clear zoning, as well as the importance of environmental heterogeneity and the control of biological invasion for the maintenance of native tree/shrub regeneration.","PeriodicalId":53662,"journal":{"name":"Feddes Repertorium","volume":"133 3","pages":"220-233"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47502569","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}
