1. Dysosmia fluminensis M. Roemer (1846: 150)

≡ Passiflora foetida [sensu Vellozo] (1831: tab. 86; 1881: 379).

≡ Passiflora foetida Linnaeus var. fluminensis (M.Roemer) Killip (1938: 499) .

Lectotype (here designated):—Illustration from Vellozo, Fl. Flumin. 9, tab. 86. 1831.

Epitype (here designated):— BRAZIL. Rio de Janeiro: Nova Friburgo, 23 November 1890, A. Glaziou 20334 (P04882507!).

Notes: —Vellozo’s Flora Fluminensis (1831; 1881), although an important work for newly described taxa from Brazil, has proven difficult to interpret for a number of reasons. It has been documented that Vellozo sent specimens to the herbarium at the Royal Museum of Lisbon (Borgmeier 1961), but all attempts to find his original collections at LISU, or other herbaria, have been unsuccessful ( Pastore 2013; also see Carauta 1973).

Originally published as Passiflora foetida, Roemer (1846) considered it different from Linnaeus’ species and thus named it Dysosmia fluminensis , which was subsequently changed to P. foetida var. fluminensis by Killip (1938). In an intensive study of the species of Passifloraceae described in the Flora Fluminensis, Cervi & Rodrígues (2010) agreed with Killip’s taxonomic assignment but did not typify the name. Thus, Vellozo’s (1831) plate number 86 is here selected as the lectotype of the name as it is the only known original material. The name P. foetida [sensu Vellozo] was validly published under Art. 38.8 and 38.9 of the ICN (McNeill et al. 2012) because the plate shows dissection of the flower, bracts, and fruit. In selecting a herbarium specimen to aid in the identification of this taxon, A. Glaziou 20334 from the type locality of Rio de Janeiro, Brazil is here chosen as the epitype.
