“…Due to the great diversity of Amaryllidaceae, mainly of the subfamily Amaryllidoideae in Brazil, many studies have recently been undertaken for taxonomic clarification and recantation of the floristic diversity of the group: Alves-Araújo et al, 2009;Amaral, 2007;Amaral-Lopes & Cavalcanti, 2015;Candido et al, 2014;Kirizawa et al, 2005;Monteiro & Oliveira, 2010;Oliveira, 2012Oliveira, , 2006Sano, 2009 andOliveira et al, 2008;2013. In our study, we propose and describe two new species of Tocantinia, contributing to the advancement of floristic-taxonomic studies in Brazilian Amaryllidoideae.…”

“…This subfamily includes important genera, such as Hippeastrum Herbert (1821: 31) with about 30 species, Habranthus Herbert (1824Herbert ( : t. 2464 with about 19 species, and Zephyranthes Herbert (1821: 36) with roughly 17 species (Dutilh & Oliveira, 2015). The genera Cearanthes Ravenna (2000: 11), Eithea Ravenna (2002: 2), Griffinia Ker-Gawler (1820: t. 444), Tocantinia Ravenna (2000: 9) and Worsleya (W. Watson ex Traub) Traub (1944: 89) are considered rare and endemic in Brazil with few species (Dutilh & Oliveira, 2015;Amaral-Lopes & Cavalcanti 2015).…”

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.

“…(Dutilh & Oliveira 2012). The morphology of Hippeastrum has not been extensively studied in Brazil, only a few systematic floristic surveys having been undertaken with native species (Dutilh 1987(Dutilh , 1996(Dutilh , 2005Amaral 2007; Alves-Araújo et al 2009). Information about the morphology and taxonomy of the genus in the state of Rio de Janeiro is still scarce, citations in lists of local floras representing the only records currently available (Araujo 2000;Alves 2001;Argôlo 2001;Braga 2004;Menezes et al 2005;Bocayuva et al 2006).…”

Hippeastrum species in areas of restinga in the state of Rio de Janeiro, Brazil: pollen characters

et al. 2013

View full text Add to dashboard Cite

The order Asparagales comprises 14 families, five of which occur in Brazil. Amaryllidaceae is a family of economic relevance and includes numerous ornamental genera. The genus Hippeastrum is widely distributed in Brazil and comprises 34 species, 11 of which occur in areas of restinga (coastal woodland) and Atlantic Forest in the state of Rio de Janeiro. The morphology of Hippeastrum has not been extensively studied in Brazil, where only a few systematic floristic surveys have been carried out with native species. In field studies and reviews of herbarium collections, we identified five Hippeastrum species occurring in areas of restinga in the state of Rio de Janeiro. The five species identified could be distinguished according to the following palynological characteristics: pollen grain size, polarity, pollen units, shape, aperture (number and type), exine sculpture, colpus length and pattern of sexine ornamentation. Of the five species identified, Hippeastrum aulicum Herb. and H. glaucescens (Ker Gawl.) Herb. were not identified in the field. Among the three species that were found in the field, H. striatum had the widest distribution in the study area, whereas the distribution of H. reticulatum was restricted to a single area of restinga, in the Jaconé district of the municipality of Saquarema. Through palynological examinations of specimens from herbaria in the state of Rio de Janeiro, we were able to confirm the identity of all five species of Hippeastrum studied. Our data represent a relevant contribution to increasing knowledge of this plant group in the region and will aid in future conservation efforts.
