Three species of non lichenized Dothideomycetes (Ascomycota) found growing on bark of native trees from the Andean Patagonian forests of Argentina are described. Melanomma subdispersum and Mytilinidion tortile are reported for the first time in South America. The distribution area of Mytilinidion andinense is expanded from Rio Negro province, where it was found the first time, to Chubut province. Descriptions, data on geographical distribution, habitat and illustrations are provided for the three species.

Mycena paranaensis and M. leaiana are very similar species from section Cespitosae, which have been confused by different authors. The aim of this paper is to clarify the species limits between M. leaiana and M. paranaensis . Mycena paranaensis is recorded for the first time for the Argentinean mycobiota, whereas M. leaiana is excluded.

Cabralea canjerana subsp. canjerana is a common species in the Atlantic Forest, occurring in several areas of this biome. Yet, little is known about its reproductive strategies. This study aims to understand the reproductive biology of this subspecies, including floral biology, sexual system, and pollination biology. Male and female plants have morphologically similar flowers, but male plants have larger inflorescences with more flowers than female plants. Female flowers remain open and receptive for two days, whereas male flowers last only one day; thus, compensating for the imbalance of the number of flowers per plant between the two sexes. Morphologically similar male and female flowers, as observed in C. canjerana subsp. canjerana , are rare among dioecious species. The high frequency of moths visiting the flowers, the timing of flower opening (anthesis) and the production of nectar suggest that moths are the pollinators of this subspecies. In contrast to the floral dimorphism found in C. canjerana subsp. polytrica , variations in floral morphology are unrelated to the plant sex in subsp. canjerana . This and other results found in this study suggest that the subspecies of C. canjerana might be different species.

A taxonomical treatment of the representatives of Cystopteris (Cystopteridaceae) occurring in Argentina, Bolivia, Brazil, Chile and Uruguay is presented. In this region, the genus is represented by three species: Cystopteris apiiformis from Argentina and Chile, C. diaphana from Argentina, Bolivia, Brazil and Uruguay, and C. ulei, endemic from Serra Dourada (Goias), Brazil. Identification keys, descriptions, comments, illustrations, the full synonymy, distribution maps, and ecological remarks for the species are presented. Four taxa: Athyrium fumarioides, C. apiiformis, C. ulei and Polypodium diaphanum are lectotypified. Two new synonyms are proposed: C. fumarioides (sensu Kunze) and C. emarginulata under C. diaphana. Cystopteris fragilis is excluded from the studied area.

Aristolochia is the only genus of the family Aristolochiaceae in Argentina, where 21 native species grow, none of them restricted to this country. A total of 10 names are subordinated as synonyms, and 32 lectotypes are designated. This work includes a key for the identification of Aristolochia species in Argentina, along with short descriptions, vernacular names in Argentina and neighboring countries, and taxonomic and nomenclatural notes for the cases where new synonyms or typification issues are resolved.

In this study we update the taxonomy and distribution of the Osmundaceae, a family of ferns that inhabits the subtropical forest and wetlands of Argentina, Paraguay and Uruguay. Currently, the family comprises four genera, two of them, with one species each, are represented in the study region. Osmunda spectabilis is accepted as a valid species, distinct from O. regalis , which is not present in the study area. Osmundastrum is recognized at the generic level with only one species Osmundastrum cinnamomeum var. cinnamomeum . A key to the genera, descriptions, relevant synonymy for South America, distributions, and illustrations of the species are included. Osmunda imbricata, Osmunda palustris and Osmunda spectabilis var. brasiliensis are lectotypified.
摘要本文对生长在阿根廷、巴拉圭和乌拉圭亚热带森林和湿地的蕨类植物Osmundaceae的分类和分布进行了研究。目前，该科共有4属，其中2属，每属1种。Osmunda spectabilis被认为是一种有效的物种，不同于研究区域不存在的O. regalis。在属级上，肉桂属(Osmundastrum cinnamomeum var. cinnamomeum)仅有一种。一个关键的属，描述，南美的相关同义词，分布，和插图的物种包括在内。凸形小龙虾、palustris小龙虾和spectabilis var. brasiliensis有典型型。

Three new combinations in Oriastrum are proposed: Oriastrum minutum from Argentina and Chile, and O. stuebelii var. abbreviatum and O. stuebelii var. argentinum from Argentina. The following taxa are newly synonymized: O. tontalensis under O. pulvinatum var. polymallum, and O. famatinae and O. stuebelii var. cryptum with O. stuebelii var. argentinum. Nine lectotypes are here proposed for: Aldunatea chilensis, A. gnaphalioides, A. lycopodioides, Carmelita formosa, Chaetanthera stuebelii var. argentina, C. villosa, Egania acerosa, E. dioica and, Tylloma limbatum. Additionally, illustrations of phyllaries and leaves for O. pulvinatum var. polymallum and O. tontalensis are provided, as well as a table featuring diagnostic characters to the varieties of O. stuebelii and O. famatinae.

We analyzed distributional data of vascular plants of the Patagonian province, in order to contribute to its biogeographic regionalization. We constructed maps with the localities of 112 specific and subspecific taxa endemic to the Patagonian steppe, obtained their individual tracks, and undertook a parsimony analysis of endemicity (PAE), in order to identify generalized tracks and test a recent biogeographic classification. The Payunia, Subandean and Central subprovinces were not supported by the plant taxa analyzed, as their respective districts were not recovered as generalized tracks. It would be important to analyze other plant and animal taxa in order to explain the inconsistencies found.
