... This species is a heliophile plant and several individuals are often found associated with crops, including coffee (Coffea arabica L.) fields. Most individuals occur along roadsides or near houses, which might result in the loss of individuals due to deforestation or road expansion Freitas et al. 2019). Following the IUCN Red List criteria (IUCN 2012;2022), A. hypoglauca qualifies as EN (Endangered) B1ab(iii)+2ab(iii), due to its small Extent of Occurrence (591,849 km²) and Area of Occupancy (36, km²); the low number of locations (only eight known locations of occurrence); and the severely fragmented and declined habitat. ...
Aristolochia hypoglauca and A. paulistana (Aristolochiaceae) are two species that inhabit the Brazilian Atlantic Forest. They highly resemble each other especially on the size and overall shape of the caudate perianth, which causes confusion in herbaria determinations. We applied geometric morphometrics (GM) to overcome this taxonomic uncertainty. GM was based on the landmark method applied to leaves of all specimens available mostly in Brazilian herbaria. The GM results supported the recognition of the two species, as the two principal components were responsible for 94.97% of the variation assessed through the principal component analysis (PCA). The Discriminant Function and the Cross-validation tests resulted in the maximum percentage of correctly classified cases (100%). The Procrustes distance (0.2252; p< 0.0001), and the Mahalanobis Distance (8.4473; p< 0.0001) provide statistical support for leaf shape differences with taxonomic significance. Thus, we revisit the taxonomy and comparative morphology of both species, and compare them with other Aristolochia species with caudate floral limb native to Brazil, and commented the phenology, distribution and habitat, and conservation status. Additionally, we proposed the epitypification of A. hypoglauca, given that the holotype does not fulfill the purpose of precise application of the name.

... Aristolochiaceae (Piperales) comprises 4 genera: Aristolochia L., Asarum L., Saruma Oliver and Thottea Rottbøll, and is distributed in tropical, subtropical and temperate zones (Wanke et al., 2006). In Brazil, the family is represented by 83 species of Aristolochia occurring in the 5 terrestrial biomes found in the country: the Caatinga, the Cerrado, the Amazon Forest, the Atlantic Forest and the Pampas (BFG, 2015;Freitas et al., 2019;Freitas, Lirio et al., 2020). The species occurring in Brazil can be recognized as vines or lianas, or more rarely, herbaceous perennials reaching up to 40 cm in height. ...
Two new occurrences of Aristolochia in Brazil are reported here. Aristolochia cremersii, hitherto known from French Guiana, was collected in Oriximiná/Pará, and A. argentina, with previously known distribution in Argentina, Bolivia and Paraguay, was recorded in Bodoquena/Mato Grosso do Sul. The latter species was identified based on photographic records. We provide descriptions, morphological comments, a preliminary extinction risk assessment (with one of them applying the rapid Least Concern method) and illustration/images of the 2 species, and finally discuss the use of photographs as valuable scientific records.
This study aimed to record the occurrence of the species Aristolochia bahiensis F. González in an area of the territory of the State of Maranhão, Brazil. The species was collected in the city of Timon, in an area of tension that brings together characteristics of the Cerrado, adjacent to Mata Ciliar. The study provides a brief characterization of the botanical family and descriptions of the genus and species, as well as data on its distribution. The species had already been found in the states of Alagoas, Bahia and Espírito Santo. In addition to portraying the geographic occurrence of the plant, a morphological characterization of the species was made, with the assembly of a board with images of the most relevant aspects of its morphology in addition to maps with its location.
