Abstract: Natural vanilla is a high-value crop with demand increasing globally. Crop wild relatives (CWR) represent valuable agrobiodiversity and are prioritized in the Global Strategy for Plant Conservation. Vanilla species are naturally rare with historically infrequent botanical collections. Despite their importance as CWR, fewer than 10% of Vanilla species have been evaluated for the IUCN Red List. Colombia is a diversity center for Vanilla species, yet many remote regions are lacking detailed floristic characterization. We show that the participation of rural communities in scientific endeavor enhances capacity to register biodiversity. We report two Vanilla species in the under-explored region of the Serranía de las Quinchas in the mid–Magdalena River valley in Colombia, including the first report for Colombia of Vanilla karen-christianae. For this, and the second species, Vanilla dressleri, we present descriptions with photographic botanical illustrations, updated distribution maps, and preliminary conservation status assessment. Both species are of elevated conservation concern, categorized as Endangered – EN: B2a,b(ii,iii,iv,v) following IUCN criteria. Within Colombia, all recorded occurrences for both species fall outside protected areas. Vanilla crop wild relatives in Colombia have urgent conservation needs. The Serranía de las Quinchas is a priority for further botanical exploration for Vanilla, as well as other protected areas with appropriate habitat. In situ conservation should be complemented with ex situ actions. Community participation in biodiversity research is recommended in this and other remote regions as an integral step towards enhancing biodiversity research and community-based conservation.

New records and conservation of Passiflora L. (Passifloraceae s.s.) in Rio de Janeiro, Brazil https://neotropical.pensoft.net/article/62045/ Neotropical Biology and Conservation 16(1): 115-128

DOI: 10.3897/neotropical.16.e62045

Authors: Michaele Alvim Milward-de-Azevedo, Natália Brandão Gonçalves Fernandes

Abstract: Passiflora L. belongs to the family Passifloraceae sensu stricto, and comprises 700–750 species. There are approximately 161 known species of the family in Brazil, of which 153 belong to Passiflora, 89 are endemic, 83 occur in the region of the Atlantic Domain; 40 occur in Rio de Janeiro State (RJ). Using field samplings techniques and scientific collection analyses, we present here new geographic records for Passiflora deidamioides Harms, P. imbeana Sacco, P. junqueirae Imig & Cervi, and P. truncata Regel for RJ, principally in the Serra dos Órgãos National Park (PARNASO). Geographic distribution data was used to calculate the Extension of Occurrence (EOO) and Area of Occupancy (AOO) of the species. Passiflora junqueirae, previously considered endemic to Espírito Santo State, now has new records for RJ. Passiflora imbeana and P. truncata are extended into RJ, being recorded there for the first time in the municipality of Teresópolis. The four species are cited for the first time in PARNASO, occurring between 1,000 and 1,700 m.a.s.l. in Montane and Upper Montane Atlantic Rainforest. We provide taxonomic information, distribution maps, and the conservation status of the species.

Invasive alien plants in Sergipe, north-eastern Brazil https://neotropical.pensoft.net/article/56427/ Neotropical Biology and Conservation 16(1): 89-104

DOI: 10.3897/neotropical.16.e56427

Authors: Juliano Ricardo Fabricante, Kelianne Carolina Targino de Araújo, Thieres Santos Almeida, João Paulo Bispo Santos, Daniel Oliveira Reis

Abstract: Biological invasions are considered one of the greatest threats to global biodiversity. In addition, they cause substantial economic impacts. However, studies about the subject in Brazil are still scarce. The aim of the present study was to prepare an inventory of non-native flora with invasive potential from Sergipe, Brazil. The inventory was carried out along the entire length of the sites. The species with potential invaders were grouped according to the biome/ecosystem and classified according to their habit and origin. Eighty-five species with invasive potential were sampled, 43 in the Caatinga, 75 in the Atlantic Forest, 36 in Sandbank and 22 in Mangrove. From these species, 17 were inventoried in all the biomes/ecosystems and 36 were observed in only one of them, six in the Caatinga, 27 in the Atlantic Forest and three in Sandbank. The number of potentially-invasive species sampled in Sergipe is alarming. The present study showed nearly twice the species listed by other authors for the entire northeast Brazil. This high number of taxa may be a consequence of facilitating the transfer of these species and the conservation conditions of the ecosystems studied in Sergipe. Another very worrying factor is that many of the species sampled are extremely aggressive and cause a series of impacts.

Re-discovery of Catasetum mojuense (Orchidaceae: Catasetinae), a poorly-known Amazonian species https://neotropical.pensoft.net/article/54142/ Neotropical Biology and Conservation 15(4): 447-452

DOI: 10.3897/neotropical.15.e54142

Authors: Felipe Fajardo Villela Antolin Barberena, Deivid Lucas de Lima da Costa, José Antônio Lima Rocha Junior

Abstract: The re-discovery of Catasetum mojuense A.T. Oliveira & J.B.F. Silva (Orchidaceae), an Amazonian species described in 1999 from the State of Pará, Brazil, is reported. In addition to geographic distribution data, a morphological description, taxonomical and ecological comments, conservation status assessment and photographs of C. mojuense are also provided. The species is characterised by having epiphytic habit, non-resupinate staminate flowers, brown-spotted petals, galeiform and smooth (no ribs) lip, lateral lobes with sparsely short-fimbriate margins and convergent antennae. Catasetum mojuense is morphologically similar to Catasetum discolor (Lindl.) Lindl, but is easily distinguished by the longer sepals and petals and the spotted petals on the staminate flowers. The new locality of occurence for C. mojuense is approximately 190 km east of the type locality, also in the State of Pará. The species is assessed as Critically Endangered. Habitat depletion and the limited number of sites of occurrence are the main concern for the conservation of C. mojuense.
