Novelties in Passifloraceae from the Brazilian Amazon

Passiflora L., the largest genus of Passifloraceae, includes about 575 species largely distributed in tropical forests of Central and South America and ca. 22 species in Southeastern Asia, Australia, and Pacific Islands (Ulmer and MacDougal 2004). In Brazil, the genus is represented by 141 species, occurring in all states (Bernacci et al. 2014). Except for classical treatments of Masters (1872), Killip (1938), and more recent papers of Cervi et al. (2012) and Milward-de-Azevedo et al. (2012), studies on Passiflora in Brazil are almost restricted to the Atlantic Forest and Cerrado biomes (Cervi and Linsingen 2008; Milward-deAzevedo 2008; Mondin et al. 2011). In the Brazilian Amazon, Passiflora is poorly known and few works were carried, such as one key for 20 species of Passifloraceae from the Adolpho Ducke Forest Reserve, in Manaus (Hopkins and Souza 1999), and also a description of Passiflora cordistipula Cervi (Cervi 2002). Recently, four new species were described for the Brazilian Amazon, Passiflora kikiana Cervi & Linsingen (Cervi and Linsingen 2010), Passiflora cristalina Vanderpl. & Zappi (Vanderplank and Zappi 2011), Passiflora fissurosa M.A.D. Souza (Souza and Hopkins 2011), and Passiflora longifilamentosa A.K.Koch et al. (Koch et al. 2013). Two taxonomic studies on the group were published by Cruz et al. (2013) Passiflora in the Urucu Petroleum Province, Coari, Amazonas, and Silva et al. (2013) with Passifloraceae in the Environmental Protection Area of Belém, Pará. However, further taxonomic studies on the genus and family are still needed for the Brazilian Amazon. After examining herbarium collections of Passiflora from MG (Museu Paraense Emílio Goeldi) and IAN (Embrapa Amazonia Oriental), as well as fresh material collected in different areas from Amazon, we found species which were not yet recorded both from Brazil and from different states of the Brazilian Amazon. This paper presents new records of Passiflora L. from the Brazilian Amazon, and contributing to the knowledge about the taxonomy and distribution of Passifloraceae in Brazil.

Passiflora L., the largest genus of Passifloraceae, includes about 575 species largely distributed in tropical forests of Central and South America and ca.22 species in Southeastern Asia, Australia, and Pacific Islands (Ulmer and MacDougal 2004).In Brazil, the genus is represented by 141 species, occurring in all states (Bernacci et al. 2014).
In the Brazilian Amazon, Passiflora is poorly known and few works were carried, such as one key for 20 species of Passifloraceae from the Adolpho Ducke Forest Reserve, in Manaus (Hopkins and Souza 1999), and also a description of Passiflora cordistipula Cervi (Cervi 2002).Recently, four new species were described for the Brazilian Amazon, Passiflora kikiana Cervi & Linsingen (Cervi and Linsingen 2010), Passiflora cristalina Vanderpl.& Zappi (Vanderplank and Zappi 2011), Passiflora fissurosa M.A.D. Souza (Souza and Hopkins 2011), and Passiflora longifilamentosa A.K. Koch et al. (Koch et al. 2013).Two taxonomic studies on the group were published by Cruz et al. (2013) Passiflora in the Urucu Petroleum Province, Coari, Amazonas, and Silva et al. (2013) with Passifloraceae in the Environmental Protection Area of Belém, Pará.However, further taxonomic studies on the genus and family are still needed for the Brazilian Amazon.
After examining herbarium collections of Passiflora from MG (Museu Paraense Emílio Goeldi) and IAN (Embrapa Amazonia Oriental), as well as fresh material collected in different areas from Amazon, we found species which were not yet recorded both from Brazil and from different states of the Brazilian Amazon.This paper presents new records of Passiflora L. from the Brazilian Amazon, and contributing to the knowledge about the taxonomy and distribution of Passifloraceae in Brazil.
Passiflora garckei is a member of the subgenus Passiflora, supersection Stipulata, section Granadillastrum.The subgenus is composed of approximately 240 species, which are characterized by exuberant flowers, corona usually divided into tracks or various colors (Ulmer and MacDougal 2004).This species occurs in Guyana, Suriname, and Venezuela, where it is usually semi-cultivated for edible fruit (Killip 1938;Ulmer and MacDougal 2004).It is now first recorded to Brazil at the greater Belém region, Pará (Figure 3).Passiflora retipetala Mast., Bull.Misc.Inform.Kew 1893: 12. 1893.Figures 1C-2B.
Passiflora retipetala is similar to Passiflora garckei, due to the 3-lobed leaves and oblong-ovate stipules, differing from the latter species by the blue color marked corona, the non-wavy apex of the filaments of the outer series, the higher number of glands on the petiole, and trochlea present.It is naturally found in Trinidad and Tobago, the Guianas, and northeastern Brazil, where it occurs at altitudes of 500-1000 m (Ulmer and MacDougal 2004).In Brazil, it was only known from the state of Amazonas (Bernacci et al. 2014).Here it is recorded for the first time from Pará state, where it was collected at the edge of the Mineração Rio do Norte railroad, growing in secondary forest (Figure 3).Sacco, Ann. XV Congr. Soc. Bot. do Brasil 1: 151. 1967.Figures 1D-2C.
