First karyological report in Larnax and Deprea (Solanaceae)

Somatic chromosomes of 12 samples belonging to seven Larnax Miers species and three Deprea Raf. species are studied. Chromosome number and karyotype analysis of both genera are reported for the first time. All taxa have 2n = 24. The most frequent haploid karyotype formula (8 of 12 samples) is 9 metacentric (m) + 3 submetacentric (sm) chromosomes, whereas L. glabra (Standl.) N.W. Sawyer and Larnax sp. display 10 m + 2 sm. Karyotypes of L. nieva S. Leiva & N.W. Sawyer and D. cuyacensis (N.W. Sawyer & S. Leiva) S. Leiva & Lezama are remarkable for the highest number of sm chromosome pairs, with 7 m + 5 sm and 5 m + 7 sm, respectively, presenting the highest intrachromosomal asymmetry index (A1), whereas Larnax sp. and L. glabra show the lowest A1. Most samples (9 of 12) examined have only one pair of chromosomes with nucleolar organiser regions (NOR), whereas L. glabra, Larnax sp., and D. cuyacensis possess two pairs of NOR. Systematic considerations about the monophyly of Larnax and Deprea are provided. The different karyotype parameters obtained, together with morphological characters, are discussed to single out the species.

A Key and Three New Species for the Re-Circumscribed Genus Deprea (Solanaceae)

Abstract Three new species of Deprea, found in Ecuador and Peru, are described and illustrated. Deprea pauciflora has close morphological affinities with D. sachapapa, from which it is readily distinguished by the hirsute leaves, heterodynamous stamens, and invaginatepyriform fruiting calyx always loosely enveloping the berry. Deprea pecaensis shows similarities to D. maculatifolia, D. dilloniana, and D. pumila, although it is characterized by a combination of 1–3 flowers per node, narrowly elliptic leaves without any white macules, corolla lobes-tube length ratio 1.5: 1.75, homodynamous stamens, non-mucronate anthers, exserted style, and membranous leaves. Lastly, D. zakii is similar to D. hawkesii and D. purpureocarpa, but it can be distinguished by a combination of a glabrous to glabrescent vegetative indumentum, a campanulate corolla with revolute lobes which are equal to or shorter than the corolla tube, short calyx lobes, and staminal filaments broadening gradually in width basipetally. Discussions on taxonomy, geographic distribution, and conservation status are provided, as well as an identification key to the 50 species of Deprea.

Phylogenetic relationships of Deprea: New insights into the evolutionary history of physaloid groups

Deprea is the genus with the second highest species richness in tribe Physalideae (Solanaceae) and comprises 50 species that are mainly distributed in the Andes of South America. The taxonomy of Deprea has been unstable after controversial hypotheses about its position and circumscription. Additionally, biogeographical inferences are only based on observations of the restricted area of distribution of some species and no ancestral area estimation have been performed. Here, we present a phylogenetic analysis and an ancestral area reconstruction of Deprea in order to establish its circumscription, resolve its position within Physalideae, and reconstruct its biogeographical history. Phylogenetic analyses were conducted using Maximum Likelihood and Bayesian approaches. Forty-three Deprea species and 26 related taxa were sampled for three DNA markers (psbA-trnH, ITS, and waxy). A Bayesian binary MCMC model was applied in order to infer ancestral areas. Deprea is resolved as a strongly supported monophyletic group according to its current circumscription and is placed within subtribe Withaninae of Physalideae. The phylogenetic relationships enabled us to solve taxonomic problems including the rejection and acceptance of previous synonyms. The most probable ancestral area for Deprea is the Northern Andes of South America and the Amotape-Huancabamba zone. Our phylogeny provides increased resolution and support for the current position and circumscription of Deprea. Better resolution of interspecific relationships was also obtained, although some affinities remain unclear. The phylogenetic and ancestral area reconstructions provide a framework for addressing taxonomic problems and investigating new evolutionary questions.

An updated phylogeny of Deprea (Solanaceae) with a new species from Colombia: interspecific relationships, conservation assessment, and a key for Colombian species

Deprea is a neotropical genus that comprises 51 species. Recent work based on molecular data has explored its monophyly and interspecific relationships, but the relationships amongst Deprea species were not entirely elucidated. The inclusion of more accessions and molecular markers in phylogenetic analysis is likely to produce more supported hypotheses. Therefore, the main objective of this study was to perform a combined phylogenetic analysis of Deprea including seven new samples representing six species and one more DNA plastid marker than in previous studies. In that process, a new species of Deprea from Colombia was discovered and is described and illustrated here. Deprea teresitae Deanna & A. Orejuela, sp. nov. is morphologically similar to D. dilloniana and phylogenetically closely related to D. hawkesii and D. harlingiana. This new species is distinguished by the combination of short calyx lobes, non-mucronate anthers, long staminal filaments and corolla lobes, and elongated appressed fruiting calyx around a subglobose green berry. The new phylogenetic results are presented, including discussion on phylogenetic interspecific relationships, taxonomy, geographic distribution, and conservation status from D. teresitae. The synonymy of Deprea sylvarum subsp. novogranatensis under D. glabra is also proposed and an identification key to the 10 Deprea species distributed in Colombia is included.
