“…Deanna et al. () placed the re‐circumscribed Deprea within Withaninae and suggested that Cuatresia could also be included, based on the phylogeny. Our analysis provides strong support for the close relationship of Aureliana to Cuatresia and Deprea , but also for the non‐monophyly of the type genus, Withania , with three species ( W. coagulans , W. riebeckii , and W. somnifera ) closely related to other taxa in Withaninae sensu Olmstead et al.…”

“…() and Särkinen et al. () recognized three subtribes of Physalideae: Iochrominae, Physalidinae and Withaninae, the last of which was recently proposed to include additional genera ( Deprea , Cuatresia ; Deanna et al., ). Nonetheless, many areas of the Physalideae remain unresolved—in particular, relationships within and among the genera of Physalidinae (Whitson and Manos, ; Zamora‐Tavares et al., ).…”

PREMISE OF THE STUDY:The evolution of novel fruit morphologies has been integral to the success of angiosperms. The inflated fruiting calyx, in which the balloon-like calyx swells to completely surround the fruit, has evolved repeatedly across angiosperms and is postulated to aid in protection and dispersal. We investigated the evolution of this trait in the tomatillos and their allies (Physalideae, Solanaceae). METHODS:The Physalideae phylogeny was estimated using four regions (ITS, LEAFY, trnL-F, waxy) with maximum likelihood (ML) and Bayesian inference. Under the best-fitting ML model of trait evolution, we estimated ancestral states along with the numbers of gains and losses of fruiting calyx accrescence and inflation with Bayesian stochastic mapping. Also, phylogenetic signal in calyx morphology was examined with two metrics (parsimony score and Fritz and Purvis's D).KEY RESULTS: Based on our well-resolved and densely sampled phylogeny, we infer that calyx evolution has proceeded in a stepwise and directional fashion, from non-accrescent to accrescent to inflated. In total, we inferred 24 gains of accrescence, 24 subsequent transitions to a fully inflated calyx, and only two reversals. Despite this lability, fruiting calyx accrescence and inflation showed strong phylogenetic signal. CONCLUSIONS:Our phylogeny greatly improves the resolution of Physalideae and highlights the need for taxonomic work. The comparative analyses reveal that the inflated fruiting calyx has evolved many times and that the trajectory toward this phenotype is generally stepwise and irreversible. These results provide a strong foundation for studying the genetic and developmental mechanisms responsible for the repeated origins of this charismatic fruit trait.

“…given its phylogenetic position outside of Physalideae. However, we included sequences of a voucher previously identified as C. harlingiana (Smith and Baum, 2006; Deanna et al, 2017, 2018), which does fall within Cuatresia and appears to belong to an undescribed taxon (appearing here as Cuatresia sp. ).…”

PREMISE OF THE STUDYThe evolution of novel fruit morphologies has been integral to the success of angiosperms. The inflated fruiting calyx, in which the balloon-like calyx swells to completely surround the fruit, has evolved repeatedly across angiosperms and is postulated to aid in protection and dispersal. Here we investigate the evolution of this trait in the tomatillos and their allies (Physalideae, Solanaceae), using a newly estimated phylogeny and a suite of comparative methods to infer evolutionary gains and losses.METHODSThe Physalideae phylogeny was estimated using DNA sequences from four regions (ITS, LEAFY, trnL-F, waxy) using maximum likelihood and Bayesian Inference. Maximum likelihood model selection was used to determine the best fitting model of trait evolution. Using this model, we estimated ancestral states along with the numbers of gains and losses of fruiting calyx accrescence and inflation with Bayesian stochastic mapping. Also, phylogenetic signal in calyx morphology was examined with two metrics (parsimony score and Fritz and Purvis’ D).KEY RESULTSThe well resolved phylogeny points to multiple taxa in need of revision, including the eight genera that are non-monophyletic as presently circumscribed. Model fitting indicated that calyx evolution has proceeded in stepwise fashion, from non-accrescent, to accrescent, to inflated. Moreover, these transitions appear to be largely irreversible. Among the 215 sampled Physalideae, we inferred 24 gains of fruiting calyx accrescence, 24 subsequent transitions to a fully inflated calyx and only two reversals. A median of 50 shifts were estimated in total across the clade from the ancestral non-accrescent calyx. Nonetheless, fruiting calyx accrescence and inflation show strong phylogenetic signal.CONCLUSIONSOur phylogeny greatly improves the resolution of Physalideae and highlights the need for taxonomic work. The analyses of trait evolution reveal that the inflated fruiting calyx has evolved many times and that the trajectory towards this phenotype is generally stepwise and directional. These results provide a strong foundation for studying the genetic and developmental mechanisms responsible for the repeated origins of this charismatic fruit trait.

“…4, for details see: Weigend 2002Weigend , 2004). Many plant groups have a centre of diversity here (Weigend et al 2005;Struwe et al 2009;Deanna et al 2018) and show a concentrated occurrence of narrow-endemic taxa in that region (Berry 1982;Ayers 1999;Weigend 2002;Weigend 2009, 2009a;Henning et al 2019). While the vegetation and flora of the inner-Andean valleys and the western slopes are relatively well-investigated, the eastern flanks of the Cordillera Central facing Amazonia are still under-collected in many areas.…”

The insectivorous genus Pinguicula occurs along the whole Andean mountain chain from Colombia-Venezuela in the north to Tierra del Fuego in the south with a short interruption in the Peruvian-Chilean desert range. This paper describes a new and striking species of Pinguicula that occurs in the south-eastern part of the Amotape-Huancabamba Zone in north Peru. It grows either as a lithophyte on moist rocks or as an epiphyte on Polylepis multijuga Pilg. in the wet highlands of the Cordillera Central. Pinguicula rosmarieae Casper, Bussmann & T.Henning, sp. nov. is clearly distinguished by a basal rosette of ovate-obovate leaves spread out flat on the ground and especially by a two-partite corolla with a straight uniform tube-spur complex, two features unknown from other Andean Pinguicula species. The morphological similarity to P. calyptrata Kunth is discussed and the habitat and distribution of P. rosmarieae are characterised.
