Pachyptera DC. is a small genus of neotropical lianas included in tribe Bignonieae (Bignoniaceae). The genus has a complicated taxonomic history but currently includes species distributed from Belize to Southern Amazon. Pachyptera is characterised by four main synapomorphies, namely, a papery peeling bark, prophylls of the axillary buds organised in a series of three, patelliform glands arranged in lines in the upper portions of the calyx and corolla tube. Furthermore, members of the genus also have stems with four phloem wedges in cross-section and conspicuous extrafloral nectaries between the interpetiolar region and at the petiole apex, although these characters are also shared with other genera of tribe Bignonieae. Here, we present a taxonomic revision of Pachyptera, which includes a complete list of synonyms, detailed morphological descriptions of species and an identification key, as well as information on the habitat, distribution and phenology, nomenclatural notes, taxonomic comments and illustrations of all the species. In addition, we designate three lectotypes, propose one new combination, raise one variety to species status and describe a new species. After these adjustments, a Pachyptera with five well-defined species is recognised.

Pachyptera DC. (Bignonieae, Bignoniaceae) includes neotropical lianas that are distributed from Belize to central Brazilian Amazon, with most species restricted to wet Amazonian forests (
This new classification recognises a monophyletic genus that is characterised by four morphological synapomorphies, namely, a papery peeling bark, prophylls of the axillary buds organised in a series of three (

Although Bignonia incarnata Aubl. was described in the same work as Bignonia kerere Aubl. (1775), the close relationship between those two taxa was not noted. In fact, Bignonia incarnata was thought to be morphologically similar and perhaps more closely related to Cydista aequinoctialis (L.) Miers by various authors (see

Names of the terminal taxa indicate the taxon in which these species were previously included. The taxonomic updates proposed here are also indicated. Relationships depicted follow Francisco and Lohmann (submitted).
Almost all Pachyptera species are found in the Amazon rainforest. Only P. kerere is widely distributed while all other species have restricted distributions. Pachyptera kerere is frequent throughout the Amazon and also distributed in Central America from Panama to Belize. Pachyptera aromatica is restricted to the Brazilian Amazon. Pachyptera erythraea is endemic to the middle Magdalena River Valley of Colombia, while P. incarnata is endemic to Eastern Amazon. Pachyptera linearis is known only by a few collections from Venezuela and Colombia.
Species of Pachyptera occur in wet terra-firme forests, generally close to water bodies or riverbanks and are also found in flooded forests such as the Brazilian igapó. The majority of Pachyptera species has seeds with thin wings that are wind dispersed, while P. kerere has thick, corky and wingless seed adapted to water dispersal (
Pachyptera includes great diversity of floral morphology that is associated with different pollination syndromes. Pachyptera aromatica has white, hypocrateriform corollas and nocturnal anthesis (
Pachyptera incarnata, P. kerere and P. linearis share infundibuliform and dorso-ventrally compressed corollas, with two longitudinal ridges in the throat that form yellow nectar guides, as well as included anthers. Pachyptera incarnata has light pink to pale purple flowers, while P. kerere and P. linearis have white to cream flowers. These flowers are classified as “Anemopaegma type” and are pollinated by large to medium-sized bees, mainly euglossine and anthophorids (
Pachyptera is a Latin derived name that means “with thick wings” (from Latin: pach = thick, aptera = without wings). This characteristic is found in the type species of the genus, Pachyptera kerere.
Habit. All species of Pachyptera are lianas, although seedlings are initially herbaceous and free standing until ca. 80 cm (grow vertically).
Stems. The stems of Pachyptera exhibit four phloem wedges in cross-section, a type of cambial variation also found in Adenocalymma, Martinella, Cuspidaria, Fridericia and Tanaecium (
Prophylls of the axillary buds. Prophylls of the axillary buds, referred to as “pseudostipules” in the past (e.g.

Extrafloral nectaries. Extrafloral nectaries (i.e. EFNs) are useful generic and species level markers within Bignonieae, aiding the identification of sterile materials (
Leaves and tendrils. As with most representatives of Bignonieae, leaves of Pachyptera are 2-3-foliate, with the terminal leaflet replaced by a trifid tendril. Tendrils are often deciduous, leaving a tiny scar in the position of tendril detachment. Leaflets can be quite variable in shape, varying even within a single species. Leaflet asymmetry is striking in the group and can help in its identification.
Inflorescences. The inflorescence of Pachyptera is a simple raceme that can originate from the apical and axillary buds, producing terminal and axillary inflorescences respectively. Racemes can be lax, with a well-developed central axis, ca. 6-24 cm in P. aromatica (Fig.
Calyx. The calyx of Pachyptera is tubular (cupular in P. erythraea) with grouped patelliform glands on the upper half (Figs
Corollas. More than half of Pachyptera species have infundibuliform and dorso-ventrally compressed corollas (Fig.
Androecium. As with most members of Bignonieae, Pachyptera has four didynamous stamens and one staminode. Filaments are usually glabrous but puberulous in P. erythraea. The anthers are generally included, but sub-exserted in P. erythraea (Fig.
Pollen. Pollen has been shown to represent a useful trait for generic delimitation within the Bignoniaceae (
Gynoecium. Members of Pachyptera have capitate, elliptic and ovate stigmas. While the style and stigma are always glabrous, the ovary is pubescent (Fig.
Fruits. Fruits are coriaceous to woody septicidal capsules, with two valves. The capsule is linear and flattened in most species (fusiform and inflated in P. kerere), puberulous, lepidote, covered with patelliform glandular trichomes and without lenticels (Fig.
Seeds. The seeds of Pachyptera are mostly oblong, thin, chartaceous to coriaceous, with membranaceous and hyaline wings, except from P. kerere in which seeds are irregularly circular and obcordate, thick, corky and wingless. Seed surface has provided excellent information for the systematics of various plant groups (
Species delimitation. Molecular phylogenetic data (Francisco and Lohmann submitted) was used to aid species delimitation. While it is understood that not all species need to be monophyletic, species are evolutionary lineages that reach a status of reciprocal monophyly in advanced stages of the speciation process (
Morphological descriptions. Morphological descriptions of all species of Pachyptera were based on extensive fieldwork and on the analysis of multiple herbarium specimens. The authors examined 378 specimens deposited in the following herbaria: A, B, COL, ESA, F, G, HB, HERBAM, HRCB, HUA, IAN, INPA, K, LINN, MBM, MG, MICH, MO, NY, NX, P, R, RB, RBR, S, SPF, SP SPSF, UEC, UFACPZ, US, VEN and WU (acronyms following Thiers 2015). Images or the actual specimens of all type materials were also analysed. Fieldwork was conducted between 2014 and 2015, in the Brazilian states of Amazonas, Pará and Roraima, the centre of diversity of Pachyptera. Specimens collected during field expeditions were deposited at SPF and MO. All accepted names are listed alphabetically, with nomenclatural discussions and citations following

Pachyptera erythraea is endemic to wet forest vegetation from the Magdalena River Valley in northern Colombia (Antioquia, Santander). Fig.
Pachyptera erythraea is distinguished by the orange to red corollas (vs. white, light pink to pale purple in all other species), cupular calyces (vs. tubular in all other species) and sub-exserted anthers (vs. included anthers in all other species). Moreover, P. erythraea is the sole species of Pachyptera with tubular-campanulate corollas. The fruit of P. erythraea is flat, without a visible longitudinal midline. The seeds are thin and winged, similar to those of P. incarnata and P. linearis. Pachyptera erythraea is closely related to P. incarnata, with which it shares a moderately to densely lepidote ovary (Fig.

The original description of this species by
Bignonia benensis was described by Britton (1990) based on a collection by Rusby 1143. This material cannot be considered a holotype because it was not cited in the protologue. Two related specimens are deposited at NY and US and one at MICH. Although there are two materials deposited at NY, only one is original material. The the other specimen is a duplicate that was originally deposited at the College of Pharmacy Herbarium, where Britton worked. Materials from this herbarium were only later incorporated into the NY collection along with other items. Therefore, the specimen originally deposited at NY (NY313133) is here designated as lectotype.
Pachyptera kerere is easily recognised by the infundibuliform, white to cream corollas, with densely pubescent ovary. The fusiform, woody, inflated (sometimes slightly flattened) fruit, with a conspicuous and raised longitudinal midline, is very distinctive. The seeds are irregularly circular and obcordate, corky and wingless.
Pachyptera kerere shares infundibuliform corollas with P. incarnata and P. linearis. However, P. kerere can be differentiated by the densely pubescent ovary (vs. sparsely pubescent ovary of P. linearis and densely lepidote ovary in P. incarnata). Furthermore, P. kerere is easily separated from P. incarnata by the white corolla (vs. light pink to pale purple corolla of P. incarnata).

Pachyptera linearis flowers in January and fruits in April.
Pachyptera linearis is a new species described here based on new morphological and molecular phylogenetic data (Fig.
Pachyptera linearis is characterised by white and infundibuliform corollas, with a sparsely pubescent and sparsely lepidote ovary. Furthermore, the capsule is linear, flattened, coriaceous to woody, with an inconspicuous longitudinal midline on the valves. The seeds are oblong, thin, coriaceous to woody, winged, with short membranaceous or coriaceous and hyaline wings. Pachyptera linearis shares the white infundibuliform flowers with its sister species P. kerere (Fig.
