Eithea lagopaivae Campos-Rocha & Dutilh, sp. nov. is described as the second species of the formerly monotypic genus Eithea. It is characterized by a one flowered inflorescence, completely hollow scape, white or lightly magenta-striated flower that is enclosed by spathe bracts fused for more than the lower fifth of its length. Comments on its range, habitat, phenology, as well as photographs and illustrations are provided. In addition, a distribution map and an identification key for the two species of the genus are presented and anatomical and ecological differences compared. Known by only two small populations exposed to several types of threats and without any guarantee of protection, E. lagopaivae is considered a Critically Endangered (CR) species.

Abstract—In the context of the revision of Amaryllidaceae tribe Griffinieae that we are preparing, we describe and illustrate a new species, Griffinia albolineata, known from a single fragment of the Atlantic Forest in the Brazilian State of Minas Gerais. It is distinguished by the foliar blade with a whitish longitudinal stripe and long-acuminate apex, unique features among the large-sized species of the genus. Additionally, we present a taxonomic reassessment of G. intermedia, described two centuries ago and historically of very uncertain identity. We provide a description and detailed distribution data, previously unpublished records, and photographs of the species in its natural habitat. We also compare the foliar anatomy and surface micromorphology of the two species. The conservation status of the two species is informally evaluated, and both are tentatively considered endangered. An identification key to the large-sized species of the genus is presented.

A família Hypoxidaceae é cosmopolita, composta por nove gêneros e aproximadamente duzentas espécies. No Brasil encontra-se representada por três espécies pertencentes aos gêneros Curculigo e Hypoxis. O presente trabalho pretende contribuir para o conhecimento das espécies de Hypoxidaceae ocorrentes no estado do Espírito Santo. Está fundamentado no estudo das coleções depositadas nos herbários visitados, coletas de campo, além da consulta a dados bibliográficos. Para o estado foi registrado somente o gênero Hypoxis, com duas espécies, H. atlantica e H. decumbens. Descrita em 2016 para os estados da Bahia e Santa Catarina, H. atlantica é confirmada para o Espírito Santo. São apresentados descrições das espécies, comentários taxonômicos, dados sobre hábitat, ecologia e distribuição geográfica, além de fotografias. Adicionalmente, é apresentada uma chave de identificação para as espécies. Palavras-chave: Asparagales, Hypoxis, restinga, taxonomia. AbstractHypoxidaceae has a worldwide distribution, with nine genera and approximately two hundred species. In Brazil, the family is represented by three species, from genera Curculigo and Hypoxis. This work aims to contribute to the knowledge of Hypoxidaceae species in the state of Espirito Santo, Brazil. It is based on the examination of collections deposited in diverse visited herbaria, on fieldwork and bibliography. Only genus Hypoxis was encountered, with two species, H. atlantica and H. decumbens. Described in 2016 for the states of Bahia and Santa Catarina, H. atlantica is confirmed for Espírito Santo. Descriptions of the species, taxonomic, habitat, ecological and distribution data are provided, with photographs. Additionally, an identification key is presented.
