During taxonomic review of the Brazilian species of the Passiflora subgenus Astrophea and P. subg Decaloba, six names published by the Brazilian botanist João Barbosa Rodrigues were found in need of discussion: Passiflora alliacea, P. amalocarpa, P. cabedelensis, P. hexagonocarpa, P. hydrophila and Tacsonia coccinea. The original illustrations are here designated as lectotypes for P. alliacea, P. amalocarpa, P. cabedelensis (a synonym of P. amalocarpa), P. hexagonocarpa, P. hydrophila (a synonym of P. costata) and Tacsonia coccinea (a synonym of P. spinosa).

Keywords: Astrophea; Decaloba; nomenclature; Passifloraceae; types

Passiflora L. is the largest genus of Passifloraceae with about 520 species (Feuillet & MacDougal 2007), the majority of which occur in the Americas and only about 20 that occur in India, China, Southeast Asia, Australia and islands of Oceania (Bernacci 2003). In Brazil, Passifloraceae occurs throughout the country and in practically all vegetation formations, with about 150 species in four genera: Ancistrothyrsus Harms, Dilkea Mast, Mitostemma Mast. and Passiflora (BFG 2015). Passiflora is divided into five subgenera with four of these, Astrophea (DC.) Mast., Deidamioides (Harms) Killip, Decaloba (DC.) Reich. and Passiflora, occurring in Brazil.

João Barbosa Rodrigues, an important Brazilian botanist, published several species descriptions and contributed immensely to the knowledge of the Brazilian flora, including important works on the families Arecaceae and Orchidaceae (Mori & Ferreira 1987). For the family Passifloraceae, more specifically the Passiflora subgenera Astrophea and Decaloba, he described four species (Passiflora alliacea, P. hexagonocarpa, P. hydrophila and Tacsonia coccinea) and two species (Passiflora amalocarpa and P. cabedelensis), respectively.

Between 1883 and 1890 Barbosa Rodrigues directed the Museu Botânico do Amazonas, adding more than 3,000 cataloged specimens to its herbarium collection. He also created the scientific journal Vellosia, in honor of Frei Velloso, which published only one issue in Manaus in the year 1888, which was subsequently removed from circulation because of a graphics problem; a second edition, with four volumes, was reprinted in Rio de Janeiro in 1891 (Sá 2001).

According to Stauffer et al. (2016), the fate of Barbosa Rodrigues’ plant collection is quite confusing and there is little information available. Many of the specimens collected by Barbosa Rodrigues, including types, were lost after the closing of the “Museu Botânico do Amazonas” in 1890 (Mori & Ferreira 1987), because during the seven years that the museum and herbarium were functioning, there were budgetary problems that prevented it from functioning as planned (Sá 2001). Some information refers to Barbosa Rodrigues while he was director of the Jardim Botânico do Rio de Janeiro, and that he kept most of his collection at his home in Rio de Janeiro. However, there are reports that the collection was lost due to a fire, while others support a theory that it was lost during a flood, and that the exsiccates that were not lost disappeared after his death (Stauffer et al. 2016).

In addition to being a botanist, Barbosa Rodrigues also was a painter, and he illustrated the species that he himself described. Recent lectotypification work on the species described and illustrated by him were undertaken by Feuillet (2010), Buzatto et al. (2011), Buzatto et al. (2013), Freitas et al. (2016), Koch et al. (2016) and Stauffer et al. (2016). Since there is no type material for these taxa, according to Art. 9.11 of the Code of Nomenclature for algae fungi and plants (McNeill et al. 2012) it is necessary to designate lectotypes.

After the review of Brazilian species of the P. subgenera Astrophea and Decaloba in Brazilian and foreign herbaria did not reveal any types for the species described by Barbosa Rodrigues, the illustrations he published for these species (Rodrigues 1888; 1891; 1901) are here designated as lectotypes. Thus, six illustrations are here designated as lectotypes of Passiflora alliacea, Passiflora amalocarpa, Passiflora cabedelensis, Passiflora hexagonocarpa, Passiflora hydrophila and Tacsonia coccinea.

A detailed study was carried out based on the princeps work for the species Passiflora alliacea, P. amalocarpa, P. cabedelensis, P. hexagonocarpa, Passiflora hydrophila and Tacsonia coccínea, and on the bibliography of Mori & Ferreira (1987), a discussion of the life of João Barbosa Rodrigues. The classification followed the guidelines established by the Melbourne Code (McNeill et al. 2012).

Passiflora alliacea was described by Barbosa Rodrigues with the type locality being a restinga environment in Rio de Janeiro. The species flowers in December and fruits in January, and the specific epithet was based on the garlic odor emitted by its fruits. Both P. amalocarpa (1888 & 1891:25) and P. cabedelensis (1891:30) were described by Barbosa Rodrigues as apetalous species, and he distinguished them from each other by the number of series of filaments on the corona and by site of collection; while the first has two series of filaments on the corona and occurs near Manaus (Igarapé do Curro, AM), the second is characterized by having four series of filaments on the corona and occurs in restinga (Cabedelo, PB). Passiflora hexagonocarpa was described by Barbosa Rodrigues from the state of Amazonas in the municipality of Manaus, with flowering and fruiting from January to March. Tacsonia coccinea was also described from a specimen from the state of Amazonas in igarapé near Manaus. Passiflora hydrophila was described from inundated sites, flooded forests of the Rio Negro, in the month of August.
