ABSTRACT As part of an ongoing project treating the ferns and lycophytes from the region of Viçosa, Minas Gerais State, Brazil, we here present the taxonomic treatment of the early divergent lineages of the leptosporangiate ferns: the families Dennstaedtiaceae, Lindsaeaceae and Saccolomataceae. We have been sampling the remnant forest patches since 2012; we also fully reviewed the collection of herbarium VIC and other online collections: F, IAN, NY, PH, RB, U, UC, UPCB, US, and WTU. In the region of Viçosa, six taxa belonging to those families occur: Dennstaedtia cicutaria and Pteridium esculentum subsp. arachnoideum (Dennstaedtiaceae); Lindsaea lancea var. lancea, L. quadrangularis subsp. quadrangularis, and L. stricta var. stricta (Lindsaeaceae); and Saccoloma elegans (Saccolomataceae). Among these taxa, only L. quadrangularis subsp. quadrangularis and S. elegans are endemic to the Brazilian Atlantic Rainforest; the remaining are widespread in the Neotropics. We present keys, descriptions, illustrations, examined specimens, and comments.

RESUMO A Ilha de São Luís, Estado do Maranhão, configura-se como uma região ecotonal, um misto de floresta úmida, mata-de-cocais, vegetação de dunas, restingas e manguezais. Diferentemente do interior do Estado do Maranhão, suas zonas costeiras possuem uma lacuna sobre o conhecimento da família Passifloraceae. Aqui, por meio de expedições de campo e consulta a herbários, nós fornecemos o tratamento taxonômico, chave de identificação e comentários sobre as Passifloraceae da Ilha de São Luís. Foram registradas dez espécies: Passiflora auriculata Kunth, P. edulis Sims, P. foetida L., P. glandulosa Cav., P. laurifolia L., P. misera Kunth, P. nitida Kunth, P. picturata Ker Gawl., P. subrotunda Mast. e P. vespertilio L. As espécies P. picturata e P. misera foram registradas pela primeira vez na Ilha de São Luís.

ABSTRACT We present herein the occurrence and distribution of the heterotrophic straminipiles collected from soil and water, submerged leaves and surface sediment from freshwater bodies at “Mosaico de Unidades de Conservação Juréia-Itatins”, a preserved conservation unit of the Brazilian Atlantic Rainforest. From 180 collected samples, we isolated 41 taxa belonging to Hyphochytriomycota and Oomycota using the multiple baiting technique, with several new taxa to the science, new occurrences to São Paulo State or Brazil, and all new citation to the studied area. These taxa were identified based on morphological and/or molecular data, with several genic regions made available in GenBank. The calculated community structure of these zoosporic organisms showed a diverse community, with few dominant taxa, without significant differences (P≤0.05) among the different types of samples.
摘要本文报道了巴西大西洋雨林保护单元“Mosaico de Unidades de conserva o jur - itatins”的土壤、水体、被淹叶片和淡水水体表层沉积物中异养线虫的发生和分布情况。利用多重诱捕技术，从180份样品中分离出了41个低壶菌科和卵菌科的分类群，其中有几个是新发现的分类群，在巴西圣保罗州或巴西有新发现，研究区均有新引证。根据形态学和/或分子数据对这些分类群进行鉴定，并在GenBank中提供了几个基因区。计算得到的虫孢菌群落结构呈现多样性，优势类群较少，不同类型样品间差异不显著(P≤0.05)。

RESUMO O Herbário VIES é uma das cinco coleções botânicas presentes no Espírito Santo e contempla o segundo maior acervo do estado. O grupo das Briófitas não foi estudado durante anos e contava com apenas cerca de 120 exsicatas até o ano de 2019, entretanto a coleção passou por uma reorganização, novos estudos estão em andamento e atualmente apresenta quase 3.000 amostras depositadas e assim é atualmente o maior acervo de briófitas do estado. Durante este processo, 242 espécimes foram identificados e reportados neste trabalho, com 121 espécies, além de novos registros para o estado. Assim, este trabalho amplia o conhecimento da diversidade de briófitas presentes no Espírito Santo e preenche parte da lacuna de estudos para este grupo no Estado.

RESUMO O objetivo deste trabalho foi avaliar a eficiência de isolados nativos e exóticos de fungos micorrízicos arbusculares (FMA) na promoção do crescimento de plântulas micropropagadas de Pseudobombax simplicifolium S. Robyns durante a fase de aclimatização. O experimento foi realizado em casa de vegetação em delineamento inteiramente casualizado em três tratamentos de inoculação; Entrophospora etunicata (autóctone), Acaulospora longula (exótico) e um grupo testemunha não inoculado. As plântulas foram aclimatizadas em solo e vermiculita (2:1 v/v) em 10 repetições para cada tratamento totalizando 30 parcelas experimentais. Ao final do experimento, mudas de P. simplicifolium micorrizadas apresentaram melhor desenvolvimento comparado às não inoculadas. Apesar do inóculo com FMA nativo de E. etunicata ter sido mais eficiente em colonizar as plantas, os incrementos na área foliar, biomassa fresca e seca foram similares aos proporcionados pela espécie exótica de FMA (A. longula). Conclui-se que durante a fase de aclimatização, mudas de P. simplicifolium têm o desenvolvimento vegetativo beneficiado pela micorrização, independente da origem dos isolados fúngicos testados nesse estudo.
摘要本研究的目的是评价本地和外来丛枝菌根真菌(amf)分离株在驯化过程中对simplicifolium S. Robyns微繁殖幼苗生长的促进作用。试验在温室内进行，采用完全随机设计，分为3个接种处理;etunicata Entrophospora etunicata(本地)，Acaulospora longula(外来)和未接种的对照组。幼苗在土壤和蛭石(2:1 v/v)中驯化，每个处理10个重复，共30个试验区。试验结束时，菌根处理的植株比未接种的植株发育更好。虽然接种天然的etunicata amf对定殖植株更有效，但叶片面积、鲜生物量和干生物量的增加与外来种amf (A. longula)的增加相似。结果表明，在驯化阶段，无论真菌分离株的来源如何，simplicifolium幼苗的营养发育都受益于菌根化。

ABSTRACT The Brazilian Amazon encompasses about 29% of the orchid species in Brazil. With the aim of contributing to the knowledge of the Amazonian flora, a taxonomic study of Orchidaceae was carried out in a forest fragment in the municipality of Capitão Poço, located in the Belém Endemism Center, the most deforested area in the Amazon. The fragment is locally referred to as Reserva São Geraldo Majela (RSGM) and is entirely surrounded by agricultural lands. Specimens were collected from February 2020 to April 2022 and deposited in the HCP herbarium, the analysis being complemented by consulting the collections of relevant herbaria. We provide descriptions and an identification key for the eight species of Orchidaceae recorded in RSGM, all of them showing a wide geographic distribution. Seven of them are epiphytes: Campylocentrum fasciola, Campylocentrum micranthum, Catasetum macrocarpum, Erycina pusilla, Notylia lyrata, Polystachya concreta, Rodriguezia lanceolata; and one is terrestrial: Oeceoclades maculata. These findings represent 65% of the previously recorded orchid species for the municipality of Capitão Poço and reinforce the importance of conserving the forest remnants in the region.
巴西亚马逊地区拥有巴西约29%的兰花种类。为了促进对亚马逊植物区系的了解，在位于亚马逊森林砍伐最严重的bel姆地方主义中心的首都 o poo市的一片森林中对兰科植物进行了分类研究。这个片段在当地被称为Reserva s o Geraldo Majela (RSGM)，完全被农业用地包围。标本于2020年2月至2022年4月收集，并存放于HCP植物标本室，并通过查阅相关植物标本室的藏品来补充分析。我们提供了8种兰科植物的描述和鉴定密钥，它们都显示出广泛的地理分布。其中7种为附生植物:片形弯曲菌、微弯曲菌、大弯曲菌、赤藓菌、野苔菌、水杨菌、水杨菌、杉木菌;另一种是陆生的:斑纹蛙。这些发现代表了capitapo poo市以前记录的兰花物种的65%，并加强了保护该地区森林遗迹的重要性。

ABSTRACT We investigated intensity and seasonality of the reproductive phenology of Passiflora cincinnata Mast. and estimated its flowering and fruiting periods by interpolation using Inverse Distance Weighting, for the first time in phenology, based on herbarium collections from Bahia State, Northeastern Brazil. Data from 249 exsiccates with flowers and/or fruits were analyzed to estimate the amplitude of flowering and fruiting and test the seasonality using the circular statistics. Passiflora cincinnata flowering and fruiting was greatest from October to May. The maps generated by interpolation showed greatest probability of flowering and fruiting between March and May in sites with mean annual rainfall rates between 500 and 1000 mm. Our results indicated seasonality of flowering and fruiting, with reduced intensities during the austral winter. The interpolation methodology can be used in a complementary or preliminary way, either to organize field visits and set up experiments, or to extrapolate field results for larger-scale views.

ABSTRACT The tetrazolium test is a fast and effective method to determine seed viability. In this context, the objective was to adapt the methodology of the tetrazolium test, in relation to preconditioning, to determine the viability (Eugenia stipitata McVaugh ssp. sororia McVaugh) under different times of immersion in solution and seed size. The seeds of E. stipitata ssp. sororia need to go through preconditioning, fractionation being an indispensable technique to be performed before immersion of the seed in the tetrazolium solution, as it allows the contact of the salt with the tissue to be analyzed, which, when feasible, staining occurs (formation of the substance triphenyl-formazan). The immersion time of 26 hours in the tetrazolium solution (1% at 26 °C) is indicated for determining the viability of E. stipitata ssp. sororia seeds, regardless of the seed mass classes used.
