Due to the differentiation of several morphological characters including mainly leaf color, shape and size, calyx, and corolla color and size, the collected material is illustrated and a subspecies new to science is here presented, Thymus numidicus subsp. vagaensis El Mokni & Domina. Discrimination of the new subspecies with T. numidicus subsp. numidicus is discussed; the ranges of variation in size and color of leaves, calyx, and corolla of the two subspecies are illustrated. Habitat, ecology, chromatographic profiles, and conservation issues are also considered. The lectotypes of the names Thymus numidicus Poir. and T. lanceolatus subsp. kabylicus Batt. are here designated and T. lanceolatus subsp. kabylicus is included among the synonyms of T. numidicus.","PeriodicalId":53662,"journal":{"name":"Feddes Repertorium","volume":"134 4","pages":"289-297"},"PeriodicalIF":0.0,"publicationDate":"2023-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48332181","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}

Wight and Arn., T. bellirica (Gaertn.) Roxb., T. chebula Retz. and T. catappa L. were studied to evaluate the chromosomal relationship corresponding with their taxonomic characters. Analysis of mitotic metaphases showed that the somatic chromosome numbers and the centromeric formulas of these species were 2n = 24 (16m + 8sm) for T. arjuna, 2n = 48 (36m + 12sm) for T. bellirica, 2n = 48 (46m + 2sm) for T. chebula and 2n = 24 (24m) for T. catappa. Two pairs of satellites were found in T. bellirica and T. catappa. Based on different karyological data, T. chebula was positioned in 1A, T. arjuna and T. catappa in 1B and T. bellirica in 2B. Based on comparative karyomorphological data, T. bellirica and T. arjuna presented more advanced features in comparison with T. chebula and T. catappa, which also correlated with the taxonomic characters in respect of the evolutionary point of view. Therefore, the present investigation effectively evaluated chromosomal relationships with morphological implications that conferred upon evolutionary changes among these four Terminalia species.","PeriodicalId":53662,"journal":{"name":"Feddes Repertorium","volume":"134 3","pages":"200-209"},"PeriodicalIF":0.0,"publicationDate":"2023-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43158191","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}

However, the cones are not always available. Thus, species identification has to be done on the base of vegetative structures. Here distinct diagnostic differences are needed to distinguish between the taxa and good macro- and micromorphological as well as anatomical features are urgently needed. In this study, the morphology of sterile shoots and the leaf anatomy of the cupressaceous genus Calocedrus were investigated. The study's aim is to find reliable diagnostic features allowing a serious identification of each distinct species in the absence of reproductive structures. A short identification key for all four Calocedrus species was prepared. It includes also the rare C. rupestris, which is missing in most of the previous works, so this gap is closed now. In addition, the study should show which ones are good diagnostic features that might be useful for preparing identification keys on the base of vegetative features also for other scale-leaved conifers.","PeriodicalId":53662,"journal":{"name":"Feddes Repertorium","volume":"134 4","pages":"271-288"},"PeriodicalIF":0.0,"publicationDate":"2023-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fedr.202300009","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45569305","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}

Wild type and anomalous shaped pollen cones were studied. It is suggested that each perisporangiate microsporangiophore represents a strongly reduced flower (lateral pollen cone) and not a peltate microsporophyll. This explains their position in the axil of a scaly pherophyll. In the wild type, the axis of the flowers is so strongly reduced that it is no longer visible and the primordia of all inserted hyposporangiate microsporangiophores get in contact and fuse to a radial synangium. In some cases, the perisporangiate microsporangiophores/flowers were reduced to a single hyposporangiate microsporangiophore. This shows that the perisporangiate microsporangiophores of Pseudotaxus are not sporophylls, but strongly reduced lateral flowers, each consisting of several lateral hyposporangiate microsporangiophores, which fuse to a radial unit. By a reduction of all pherophylls in the Pseudotaxus inflorescence, the flower-like Taxus pollen cone structure is formed, which however represents an inflorescences with flowers reduced to perisporangiate microsporangiophores. If in Taxus pollen cones the lateral flowers get reduced to a single hyposporangiate microsporangiophore, the Torreya pollen cone is formed. In this case, the lateral hyposporangiate microsporangiophores of Torreya correspond to strongly reduced flowers and not to dorsiventral sporophylls.","PeriodicalId":53662,"journal":{"name":"Feddes Repertorium","volume":"134 3","pages":"149-156"},"PeriodicalIF":0.0,"publicationDate":"2023-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fedr.202300002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48753986","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}
