The Hookeriales are evaluated to discern familial limits. Five families are recognized in the order: Hookeriaceae, Leucomiaceae, Daltoniaceae, Callicostaceae, and Adelotheciaceae fam. nov. Chaetomitrium Dozy & Molk., Chaetomitriopsis. Fleisch., Dimorphocladon Dix., and Elharveya Crum are transferred to the Hypnaceae. Hookeriopsis (Besch.) Jaeg. is split into four genera: Hookeriopsis s. str., Brymela Crosby & Allen, Thamniopsis (Mitt.) Fleisch., and Trachyxiphium Buck, gen. nov. The following new combinations are proposed to coincide with the recognition of these four genera rather than Hookeriopsis s. lat.: Brymela acuminata, B. callicostelloides, B. cuspidata, B. fissidentoides, B. fluminensis, B. obtusifolia, B. parkeriana, B. rugulosa, B. websteri, Thamniopsis cheiloneura, T. cruegeriana, T. diffusa, T. incurva, T. langsdorffii, T. pappeana, T. purpureophylla, T. secunda, T. sinuata, T. terrestris, T. undata, T. utacamundiana, T. versicolor, Trachyxiphium aduncum, T. guadalupense, T. heteroicum, T. hypnaceum, T. pernutans, T. subfalcatum, T. tenue, T. vagum, and T. variable. Excluded species are treated as Isopterygium plumicaule, Schizomitrium cirrhosum, and S. subsecundum. Schizomitrium belangerianum (Besch.) Buck, comb. nov. is considered distinct from S. depressum (Hedw.) Buck & Steere, and S. pallidum (Hornsch.) Crum & Anders. is shown to have a smooth seta sometimes. The taxonomy of the aquatic species of Cyclodictyon Mitt. and Lepidopilum (Brid.) Brid. is clarified, resulting in the recognition of three species, Cyclodictyon subtortifolium (Bartr.) Buck, comb. nov., C. roridum (Hampe) Kuntze and L. tortifolium Mitt. Two new combinations are proposed in Calyptrochaeta Desv., C. setigera and C. albescens. 相似文献

Kelly W. Allred 《Brittonia》1984,36(4):382-395
The morphology of the Purpureae Group of North AmericanAristida is assessed by principal components and statistical analyses. Long considered a complex of about eight species, a mosaic of intergrading phenetic forms is revealed and the complex is reduced to one species with seven varieties. The taxa that are recognized areAristida purpurea var.purpurea, var.nealleyi (comb. nov.), var.curvifolia (comb. nov.), var.parishii (comb. nov.), var.wrightii (comb. nov.), var.fendleriana, and var.longiseta. A key and synopses for the varieties are provided. 相似文献

The nomenclatural and taxonomic history of the genusPerama Aubl. (Rubiaceae) is discussed. The major trends of evolution within the genus are characterized, and the sections of the genus are delimited. A new section,Diperama Kirkb. & Steyerm., is described. The distribution of the genus is updated, and centers of species concentration are indicated. A complete synonymy is given for the genus, and the type species cited. An artificial key to the species is given ; a new combination,P. parviflora (Standl.) Kirkb. & Steyerm., is mads; and three new species are described,P. harleyi Kirkb. & Steyerm.,P. irwiniana Kirkb. & Steyerm., andP. sparsiflora Standl. ex Steyerm. & Kirkb. 相似文献

Three new species ofThelypteris are described and illustrated:T. littoralis andT. paranaensis, endemic to the rainforest of the southern Brazilian Atlantic coast, andT. multigemmifera, endemic to inland gallery forests of the São Paulo state. In addition, four new combinations are made:T. cutiataensis (Brade) Salino,T. iguapensis (C. Chr.) Salino. A new name is proposed forDryopteris lugubris var.quadrangularis:T. montana Salino. The species treated here belong toThelypteris subg.Goniopteris due to the indument of furcate and stellate trichomes. 相似文献

Main conclusion
Vavilovia formosa (Stev.) Fed. is a scientifically valuable common ancestor of the plant tribe Fabeae and also important in breeding and agronomy studies of the cultivated Fabeae, but it is close to extinction. A concerted academic and geovernmental effort is needed to save it.Abstract
Since 2007, an informal international group of researchers on legumes has been working to increase awareness of Vavilovia formosa (Stev.) Fed., a relict and endangered wild-land relative to crop plant species. A majority of the modern botanical classifications place it within the tribe Fabeae, together with the genera vetchling (Lathyrus L.), lentil (Lens Mill.), pea (Pisum L.) and vetch (Vicia L.). V. formosa is encountered at altitudes from 1,500 m up to 3,500 m in Armenia, Azerbaijan, Georgia, Iran, Iraq, Lebanon, Russia, Syria and Turkey. This species may be of extraordinary importance for broadening current scientific knowledge on legume evolution and taxonomy because of its proximity to the hypothetical common ancestor of the tribe Fabeae, as well as for breeding and agronomy of the cultivated Fabeae species due to its perenniality and stress resistance. All this may be feasible only if a concerted and long-term conservation strategy is established and carried out by both academic and geovernmental authorities. The existing populations of V. formosa are in serious danger of extinction. The main threats are domestic and wild animal grazing, foraging, and early frosts in late summer. A long-term strategy to save V. formosa from extinction and to sustain its use in both basic and applied research comprises much improved in situ preservation, greater efforts for an ex situ conservation, and novel approaches of in vitro propagation. 相似文献20.
