O sistema de classificação adotado para as samambaias é o proposto por Smith et al (2006), já para as licófitas, segue-se Kramer & Green (1990). A abreviação dos nomes dos autores está de acordo com Pichi Sermolli (1996).…”

Resumo -É apresentado o levantamento das licófitas e samambaias do Parque Metropolitano de Pituaçu, Salvador, Bahia. Foram registradas 36 espécies, pertencentes a 22 gêneros e 14 famílias. As famílias mais representativas foram Pteridaceae, com 11 espécies distribuídas em cinco gêneros (Acrostichum, Adiantum, Pityrogramma, Pteris e Vittaria), e Thelypteridaceae, com seis espécies distribuídas em dois gêneros (Macrothelypteris e Thelypteris). Os gêneros com maior número de espécies foram Adiantum (6) e Thelypteris (5). A maioria das espécies apresentou-se como herbácea e terrícola. Este é o primeiro estudo abordando exclusivamente as licófitas e samambaias em um remanescente florestal urbano na cidade de Salvador. Palavras-chave adicionais: biodiversidade, florística, Mata Atlântica, pteridoflora.Abstract (Lycophytes and ferns from the Parque Metropolitano de Pituaçu, Municipality of Salvador, Bahia, Brazil) -This work presents the survey of lycophytes and ferns from the Parque Metropolitano de Pituaçu, Salvador, Bahia State. The 36 registered species belong to 22 genera and 14 families. The most representative families were Pteridaceae, with 11 species in five genera (Acrostichum, Adiantum, Pityrogramma, Pteris and Vittaria), and Thelypteridaceae, with six species in two genera (Macrothelypteris and Thelypteris). The genera with higher number of species were Adiantum (6) and Thelypteris (5). The majority of the species was herbaceous and terrestrial. This is the first study addressing exclusively lycophytes and ferns in a urban forest remnant in Salvador City.

<strong>Corrections to <em>Phytotaxa</em> 19: Linear sequence of lycophytes and ferns</strong>

After the publication of our A linear sequence of extant families and genera of lycophytes and ferns (Christenhusz, Zhang & Schneider 2011), a couple of errors were brought to our attention:Platyzoma placed in Pteris (Pteridaceae), and correcting erroneous combinations made in Pteris of Gleichenia species.In the New Combinations section on page 22, we attempted to provide new combinations for the genus Platyzoma R.Br., which is embedded in Pteris L. (Schuettpelz & Pryer 2007, Lehtonen 2011. When doing so, we made the unfortunate choice to follow the treatment of Platyzoma by Desvaux (1827), which included several additional species of Gleichenia, instead of the modern treatment of Platyzoma in which only the species Platyzoma microphyllum Brown (1810: 160) is included. Only that name needed to be transferred. This resulted in the creation of a number of unnecessary new names and combinations of Australasian Gleichenia, for which we apologise. We erroneously provided names in Pteris for Gleichenia dicarpa R.Br., G. alpina R.Br. and G. rupestris R.Br., which are all correctly placed in Gleichenia and not in Pteris. Therefore these new names are to be treated as synonyms. Gleichenia speluncae R.Br. and its combination in Pteris are synonyms of G. rupestris.To complicate matters, the combination 'Pteris microphylla' is already published earlier [by Cavanilles (in Swartz 1806: 324, nomen), by Cunningham (1836: 366), and by Colla (1836)] and is therefore not available for this taxon. We chose Platyzoma recurvum Desv. to make the combination for this taxon, an unfortunate choice, because that name is synonymous to Gleichenia microphyllum R.Br., not Platyzoma microphyllum R.Br.Unfortunately type specimens of Platyzoma ferruginea and P. latum could not be located, but based on their descriptions they appear both to be synonymous to Dicranopteris linearis (Burm.f.) Underwood (1907: 250). Of this species several varieties are known to occur in Australia and it is likely that these two names apply to different varieties, although it may not be certain to which one, due to the absence of original material to verify.Below we provide an overview of the taxa that we incorrectly applied, and we formally synonymise our superfluous new names in Pteris that are underlined for convenience.

“…It contains about 11 extant species in two genera, Dipteris Reinw. 1825 and Cheiropleuria C. Presl 1851 (Kramer et al 1990; Kato et al 2001). The two genera share a characteristic venation pattern with many orders of veins that are highly reticulated and form a dense meshwork of areoles with included free-ending veinlets (Holttum 1954;Kramer et al 1990;Kato et al 2001).…”

Monotypic colonies of Clathropteris meniscioides (Dipteridaceae) from the Early Jurassic of central Patagonia, Argentina: implications for taxonomy and palaeoecology

A collection of over 130 specimens of the fossil dipterid fern Clathropteris meniscioides (Brongn. 1825) Brongn. 1828 from in-situ colonies in the Lower Jurassic of Chubut, Argentina, provides evidence for population-level morphological variation within the species and palaeoecology of the site. Characters such as angle of insertion of secondary veins, tertiary vein arrangement and tooth depth were observed to vary between specimens, and the total range of variation captured by this population was found to overlap and intergrade with the descriptions of several previously identified Clathropteris species. This suggests that species delimitations based on minor differences in such characters should be regarded with skepticism, and that the current number of species ascribed to this genus may be artificially inflated. Abundant C. meniscioides fossils at different development stages buried together in a single, thick bed of sheet-flood deposits provide evidence for the species having formed large, pure colonies in open, disturbed floodplain areas. The characteristic and extremely high leaf-vein densities would have allowed for greater carbon assimilation and rapid growth rates. Altogether, this suggests that the species was a fast-growing pioneer species of floodplains, a prominent part of the Early Jurassic vegetation in Gondwana, and a likely food source for large herbivorous dinosaurs common at that time.
