Introduction
Passionflowers (Passiflora L., Passifloraceae) are an easily recognizable group due to their many, and often striking, morphological features. The genus is represented in the New World tropics by at least 580 recognized species (Ocampo Pérez and Coppens d’Eeckenbrugge, 2017) with potentially many more undescribed. Section Dysosmia DC., one of the infrageneric groups accepted by Feuillet and MacDougal (2003) in subgenus Passiflora supersection Stipulata Feuillet & J.M. MacDougal, is among the most widespread and taxonomically complicated in the genus and can be found from the southern United States of America through Argentina and throughout the West Indies. Mexico is a hotspot of diversity within section Dysosmia, which harbors 12 of the 30 taxa currently recognized in the section (Vanderplank, 2013) including two major species complexes: Passiflora ciliata Aiton and P. foetida L.
Like other members of supersection Stipulata, and subgenus Passiflora more generally, section Dysosmia has showy flowers, large involucral bracts, and conspicuous stipules. Unique to the section, however, are a suite of characters that are found nowhere else in the genus, including highly divided bracts and stipules and ubiquitous glands across the vegetative features. The latter are responsible for the often fetid or pungent smell associated with many of the taxa that belong to this section. These features may indeed represent synapomorphies for the section, but no phylogenetic studies to date have focused on Dysosmia in its entirety or aimed to test the assumptions of monophyly.
One of the oldest names attributed to section Dysosmia, Passiflora hibiscifolia Lam. (Fig. 1), was first described in 1789 by Jean-Baptiste Lamarck from material cultivated at the Jardin des Plantes (“Jardin du Roi”) in Paris, France.
Lamarck (1789) believed that the material for this plant originated in South America, but Killip (1938) surmised its origin to be somewhere in Central America based on the distribution inferred from herbarium collections known at the time. Subsequent taxonomic combinations based on this basionym (see Taxonomy below) have shuffled the rank and specific affinity of the taxon from a species of Passiflora, to that of a segregate genus, Dysosmia (DC.) M. Roem. (Roemer, 1846), to a variety of P. foetida (Killip, 1938). In his synopsis of the section, Vanderplank (2013) recognized the taxon as P. ciliata var. hibiscifolia (Lam.) Vanderpl., largely on account of its glabrous leaves (as P. ciliata (sensu lato) has), and is the currently accepted name.
Several other taxa with gross morphological similarities to P. ciliata var. hibiscifolia are found throughout Mexico and Central America, including P. liebmannii Mast. While this particular name has been synonymized with the taxon of interest in the past (Killip, 1938; Vanderplank, 2013), other names have not been critically investigated in this manner. Furthermore, while the taxon’s glabrous vegetative features and red fruit clearly ally this taxon with P. ciliata (sensu lato), the taxonomic affinity between the two has remained unclear.
The objective of this study is to evaluate the biological distinctness of the organism currently known as P. ciliata var. hibiscifolia and provide evidence for its taxonomic recognition.
Materials and Methods
A total of 217 herbarium specimens, including the holotype of Passiflora hibiscifolia (Fig. 2), and 27 verified iNaturalist observations (iNaturalist Network, 2018) were examined for this study. In addition, type material for several other morphologically similar taxa was also investigated: P. foetida var. maxonii Killip, P. foetida var. nicaraguensis Killip, P. foetida var. subpalmata Killip, P. liebmannii, and the current parent taxon, P. ciliata.
The herbaria consulted were ASU, B, C, DUKE, E, F, IND, LINN, MEXU, MO, NY, P, RSA, TEX-LL, and US (codes follow Thiers, 2018). Coordinates from these observations were curated and mapped using SimpleMappr.net (Shorthouse, 2010). All examinations were made using an Olympus SZ61 stereomicroscope (Olympus, Center Valley, USA) and micrographs were taken with an Olympus SC30 camera (Olympus, Center Valley, USA).
Results and Discussion
Intensive morphological investigations revealed that the taxon currently recognized as Passiflora ciliata var. hibiscifolia possesses a suite of traits that are absolutely unique to the entity (Table 1).
Trait | Passiflora hibiscifolia Lam. | P. ciliata Aiton (sensu stricto) | P. foetida L. var. maxonii Killip | P. foetida L. var. nicaraguensis Killip | P. foetida L. var. subpalmata Killip |
Stem pubescence | Glabrous | Glabrous | Pilosulous | Glabrous | Glabrous |
Stipules | Glabrous | Glabrous | Pubescent | Glabrous | Pubescent |
Foliar pubescence | Glabrous | Glabrous | Pilosulous | Glabrous | Hirsutulous |
Leaf lobing | 3-5 lobed | 3- to sub 5-lobed | 3-5 lobed | 3-lobed | 3-5 lobed |
Foliar glands | Lepidote, spheroidal | Capitate long-stipitate (margins only) | Pyriform long-stipitate | Capitate long-stipitate (margins only) | Pyriform long-stipitate |
Leaf margins | Entire to sparingly crenate | Coarsely dentate to ciliate | Ciliate | Ciliate | Ciliate |
Involucral bracts | Bi- to tripinnatisect | Bi- to tripinnatisect | Bi- to tripinnatisect | Bi- to tripinnatisect | Bipinnatisect |
Perianth color | Lavender | Pink-white | “Pale purple” | Pink-white | Unknown |
Fruit color | Red | Red | Red | Red | Unknown |
Among the most distinguishable traits are ubiquitous spheroidal, lepidote glands (Fig. 3) on the abaxial surface of the leaves which are always glabrous and deeply 3-5-lobed.
The suite of exclusive and consistent micro- and macromorphological traits indicate that this taxon is distinct from all other members of section Dysosmia, including the species to which it is currently assigned, P. ciliata (sensu stricto). On account of this evidence, and following the guidance of the Unified Species Concept (de Queiroz, 2007), this taxon deserves recognition at the rank of species as Passiflora hibiscifolia.
Passiflora hibiscifolia is easily recognizable by its unique morphological features and is the most regularly encountered Dysosmia taxon in the state of Oaxaca (Mexico). Confirmed individuals of this taxon are also found in the Mexican states of Chiapas, Guerrero, Jalisco, Michoacán, Morelos, Nayarit, Puebla, Tabasco, and Yucatán (Fig. 4).
One of these collections from the state of Puebla, Liebmann 4078 collected in 1842, became the basis for Masters’ Passiflora liebmannii (Masters, 1872) but unequivocally represents P. hibiscifolia based on the uncommon traits that they share. The name Passiflora hibiscifolia, though, has priority over P. liebmannii in accordance with Article 11 of the current International Code of Nomenclature (Turland et al., 2018).
This species is clearly closely related to P. ciliata based on the glabrous vegetative features and red fruit but differs in several ways, namely the lepidote foliar glands, the lavender perianth, deep purple coronal filaments, and the entire to sparingly crenate leaf margins in P. hibiscifolia. By comparison, P. ciliata (sensu stricto) has capitate long-stipitate foliar glands (restricted to the margins), a pink-white perianth, magenta corona filaments, and often coarsely dentate or ciliate leaf margins. The suite of traits of the latter species are also found in another taxon, P. foetida var. nicaraguensis, and likely represents the same organism (Svoboda, 2018).
Other taxa, namely P. foetida var. maxonii and P. foetida var. subpalmata, appear similar based on gross vegetative morphology but differ in having pubescent leaves and pyriform long-stipitate glands. Vanderplank (2013) included several pubescent specimens in his circumscription of P. hibiscifolia (as P. ciliata var. hibiscifolia), but this is in direct conflict with the protologue and type specimen which both indisputably represent a completely glabrous plant. Therefore, this name is confined to glabrous specimens with the morphological features mentioned above.
