Macromitrium catharinense Paris is a poorly known moss of the family Orthotrichaceae reported from Brazil. In the present paper, Macromitrium catharinense is taxonomically re‐evaluated, resulting in the synonymization of M. drewii H. Rob. from Ecuador and M. catharinense var. gracilius (Müll. Hal.) Paris from Brazil. The phenetic relationships between M. catharinense and other closely related species of Macromitrium from Brazil and Ecuador are also discussed. 相似文献

Abstract Oncophorus dendrophilus is described from two upland forest localities in the Paphos District of Cyprus, and from the White Mountains of Crete. It is characterized by its bistratose upper leaves with bistratose streaks extending 3/4 of the way to the leaf base, 2–3 stratose margins and large spores. The new species may represent a relictual Tertiary element in the eastern Mediterranean flora, or it may be a recent derivative from the widespread Holarctic species O. wahlenbergii. 相似文献

Abstract Macrocoma lycopodioides (Schwaegr.) Vitt is the correct name for those southern African specimens of the genus which are characterized byfragile leaves, bistratose upper leaf cells, peristome reduced to a double basal membrane, hairy calyptras, and dioicous sexual condition. A key is given to the four African members of Macrocoma. The habit drawing provided by Schwaegrichen in his original 1827 protologue of Macromitrium lycopodioides is remarkably similar to one portion of the collection presently found in his herbarium, and this portion of his specimen is suggested as the most appropriate Lectotype. Historically M. lycopodioides has been confused with various taxa, but in particular with M. tenue and a discussion is given of the treatment of the names in the 1800's. 相似文献

AbstractNew taxonomic observations, based on rhizoidal and protonemal gemmae of material from southern Europe and the Macaronesian Islands, are given in this work for sibling taxa of the Gymnostomum calcareum Nees & Hornsch. complex. Gymnostomum calcareum var. atlanticum Sérgio from the Iberian Peninsula, Madeira and Azores is described as a new variety, and its diagnostic characters are described and illustrated. This moss has a bistratose margin in the upper parts of the perichaetial and vegetative leaves, and the perichaetial leaves are markedly acute. It is closely related to Gymnostomum lanceolatum Cano, Ros & J. Guerra, here reduced to a variety of G. calcareum. The occurrence of fusiform or claviform protonemal gemmae provides a diagnostic feature for the different taxa. 相似文献

Abstract Fissidens subpulchellus Norkett in Gangulee is critically revised, and reduced to the synonymy of F. pulchellus Mitt. A new species, Fissidens longtonianus Z.Iwats. &; Tad.Suzuki, is described from India. This moss was collected on a branch in Jdukki District, South India, and is separated from F. pulchellus Mitt. by its smooth laminal cells, shorter setae and larger, smooth spores. 相似文献

Macromitrium densum Mitt. (from Nepal) is well differentiated from other Asian congeners by its lingulate and strongly rugose leaves having cucullate, obtuse to retuse apices with a mucro, distinctly bulging upper and median leaf cells, and tuberculate lower and basal cells. Comparisons of the type and other specimens of M. brevissimum Dixon from Thailand with those of M. densum show that they belong to a single species, and hence, that the names are synonyms. By including M. brevissimum, the geographic range of M. densum is considerably expanded to cover Nepal, Thailand to north Peninsular Malaysia and Vietnam. The phenetic relationship between M. densum and other species of Macromitrium is also discussed. 相似文献

Abstract Renauldia paradoxica, a new Pterobryaceous moss from western Panama, differs from all other species of Renauldia by its long, narrowly acuminate leaves. This species fits somewhat uncomfortably in Renauldia and appears to occupy a position intermediate between Renauldia, Orthostichidium, and Pterobryopsis. 相似文献

AbstractA new species, Pleuridium curvisetum, is described. It has an arched seta similar to that of P. arnoldii and was collected, sometimes in association with that species, in alpine country in Australia. P. arnoldii was first recorded from New Zealand. A comparison of the two species revealed some features, including a bistratose margin to the leaf subula, not previously reported for P. arnoldii. 相似文献

Background: Antagonistic interactions, such as parasitism and herbivory, are generally specialised and have a strong phylogenetic signal for specialisation. As lianas and trees interact antagonistically, we expect to find phylogenetic signal for specialisation.Aims: We aimed to answer the following questions: (1) Is the liana–tree network specialised? (2) Is the specialisation of liana–tree network related to the abundance of both the life forms? (3) Is liana and tree specialisation related to species phylogeny? (4) Do phylogenetically related liana species occupy phylogenetically related tree species, and vice versa?Methods: For three areas in southern Brazil, we calculated the specialisation value of each liana and tree species (d') and of the entire network (H2′). Binomial regression and null models were used to test the role of abundance on d' and H2′, respectively. We searched for the presence of phylogenetic signal with phylogenetic independent contrasts for d'. We also compared the similarity of species sets and their interaction with phylogenetic distance between them using Mantel test.Results: All three networks had significant values of H2′, but the values of d' did not have significant phylogenetic signals. Closely related lianas did not share similar host-tree assemblages and vice versa. Rare species were more specialised than abundant species, and abundance did not influence H2′.Conclusions: Our study indicates that the significant H2′ may be due to co-evolution in some lineages of lianas and trees. Nevertheless, the abundance of species may also play an important role in species interaction, mainly rare species. 相似文献

AbstractThe main features to distinguish the seven native Utricularia species occurring in central Europe are found in flower shape, but being rarely flowering identification is often doubtful and uncertain. A recent morphometric work highlighted that there are no univocal reliable extra-floral morphological features allowing a safe identification at species level. Therefore, DNA barcoding approach is attempted here. Molecular analyses were performed to search for DNA barcodes using nuclear ITS (rDNA), plastid (cpDNA) trnL-trnF IGS and rps16 intron sequences. Generally, the barcoding approach failed to discriminate Utricularia species, although it could be of some help in the U. minor aggregate. With few exceptions, U. bremii shows peculiar DNA regions different from U. minor for both plastid markers investigated. However, interesting hypotheses could be derived from the obtained networks, including hybridization events to explain the rise of mostly sterile species, such as U. stygia. This species clusters with the other species of the U. intermedia aggregate in plastid phylogenetic graphs, while it is closely related to species of the U. minor aggregate in ITS phylogenetic graphs. Additionally to U. stygia, U. ochroleuca also shows some incongruences in the different markers, at least for some accessions, pointing to the possible occurrence of hybrids. 相似文献

Based on field investigations as well as morphological and molecular systematic studies we found a new species of Bothriospermum which can be easily distinguished from all other known congeneric species by its unlobed faucal appendages and very long styles. We conducted molecular phylogenetic analyses based on a combined dataset from nrITS, plastid rps16, trnL‐trnF and trnG‐trnS regions. The results indicated that the new species indeed belongs in Bothriospermum and that it is well separated from other congeneric clusters, but that the genus Bothriospermum is paraphyletic with Nihon and Thyrocarpus clusetered within it. As a result, Bothriospermum longistylum sp. nov. is described and illustrated here. A revised key to species of Bothriospermum and a distributional map are also presented. 相似文献

AbstractThe moss Hypnum cupressiforme var. heseleri is reported new to the British Isles and its status is discussed. Line drawings and a photographic illustration are provided. It was found growing on an apple tree on the Royal Estate, at Flitcham in West Norfolk. It differs from other species of Hypnum in its distinctive rounded-concave leaf form and julaceous branches. The habitat and ecology are broadly similar to those in the other European sites from which this moss has been reported. 相似文献

A taxonomic study of the genus Padina from Japan, Southeast Asia, and Hawaii based on morphology and gene sequence data (rbcL and cox3) resulted in the recognition of four new species, that is, Padina macrophylla and Padina ishigakiensis from Ryukyu Islands, Japan; Padina maroensis from Hawaii; and Padina usoehtunii from Myanmar and Thailand. All species are bistratose and morphologically different from one another as well as from any known taxa by a combination of characters relating to degree of calcification; the structure, position, and arrangement of hairlines (HLs) and reproductive sori; and the presence or absence of rhizoid‐like groups of hairs and an indusium. Molecular phylogenetic analyses demonstrated a close relationship between P. ishigakiensis, P. macrophylla, P. maroensis, and Padina australis Hauck. The position of P. usoehtunii, however, was not fully resolved, being either sister to a clade comprising the other three new species and P. australis in the rbcL tree or more closely related to a clade comprising several other recently described species in the cox3 tree. The finding of the four new species demonstrates high species diversity particularly in southern Japan. The following characters were first recognized here to be useful for species delimitation: the presence or absence of small rhizoid‐like groups of hairs on the thallus surface, structure and arrangement of HLs on both surfaces either alternate or irregular, and arrangement of the alternating HLs between both surfaces in equal or unequal distance. The evolutionary trajectory of these and six other morphological characters used in species delineation was traced on the phylogenetic tree. 相似文献

Aspidistra obtusata is described and illustrated as a new species from southern Vietnam. The new species resembles A. truongii, but differs in smaller diameter of perigone (12.6–14.9 mm vs 25–35 mm), shape of tepals (elliptic, obtuse vs triangular‐ovate) and pistil (widely obconic vs mushroom‐shaped). A molecular characterization of the new species (based on data of plastid psbA‐trnH and nuclear 5S‐NTS regions) is also given, and compared with the most similar congeners. 相似文献

Abstract Gradsteinia torrenticola Ochyra, Schmidt & Bültmann sp. nov. (Donrichardsiaceae), known from a single locality in a waterfall on Tenerife in the Canary Islands, is described and illustrated. This aquatic moss is primarily characterized by its irregularly bi- to unistratose laminae with scattered 3–4 stratose ridges and crests giving the leaf surface an uneven and rough appearance, the single but mostly forked and spurred costa, and the leaf margin with frequent polystratose limbidia of varying degrees of completeness. An assessment of the relationships of this new species is troublesome due to the sterile condition of the plants. Because of the structure of the leaf laminae, it is included in the genus Gradsteinia Ochyra which, so far, is known only from the Colombian Andes. 相似文献
