Three new species of Heliotropium sect. Heliothamnus (Boraginaceae) from Peru

Phytotaxa (2012)

Federico Luebert Maximilian Weigend

Three new species of shrubby Heliotropium sect. Heliothamnus endemic to the Andean inner valleys and the eastern and western slopes of the Peruvian Andes are described as Heliotropium maranjonense, H. pamparomasense and H. oxapampanum. Heliotropium oxapampanum is the first species of the genus described from riparian habitats in the cloud forest. Heliotropium pamparomasense is the tallest species known in the group and forms shrubs to 4 m high with huge inflorescences. Notes on diagnostic characters, distribution and illustration are provided for each species.

Phylogenetic relationships and generic re‐arrangements in “South Andean Loasas” (Loasaceae)

Taxon (2017)

Rafael Acuña Stella Fließwasser Markus Ackermann Tilo Henning Federico Luebert

Abstract Loasaceae, a mostly American group, is one of the largest families of Cornales. In spite of considerable progress over the last 20 years, the relationships of some clades remain controversial, especially in the “South Andean Loasas” (SAL— Blumenbachia, Caiophora, Loasa, Scyphanthus ). The present study addresses the phylogenetic relationships in SAL employing four plastid markers ( rps16, trnL‐trnF, trnS‐trnG, matK ) and ITS and aims at resolving the systematics and evolution of the group. Sequences obtained from a total of 59 SAL species (ca. 70% of the total, representing all lineages in the group) and 25 outgroup taxa were analysed using maximum likelihood and Bayesian inference approaches. ML best and BI strict consensus trees showed no significant differences in their topologies. Our results confirm that two species of Loasa ser. Malesherbioideae are not part of the SAL clade, but should be included in Presliophytum, a result which is here formalized. Blumenbachia (including sect. Angulatae and sect. Gripidea ) is confirmed as a monophylum with high support. Loasa has to be redefined and restricted to a clade including only ser. Deserticolae, ser. Floribundae, ser. Loasa and ser. Macrospermae. Scyphanthus and Caiophora both are each monophyla and sister groups, but with two clades of Loasa as successive sister groups: ((( Caiophora+Scyphanthus )+ Loasa ser. Pinnatae )+( L . ser. Volubiles + L . ser. Acaules )) in a very well‐supported clade. Accordingly, Caiophora, Loasa ser. Pinnatae, L . ser. Volubiles , L. ser. Acaules and Scyphanthus could be included into a single genus, with Scyphanthus taking priority over Caiophora, creating a fairly heterogenous genus of ca. 52 species and requiring 50 new names. Alternatively, the clades Loasa ser. Pinnatae and L . ser. Volubiles + ser. Acaules can be removed into new segregate genera, which is here argued for and which requires the creation of only 16 new names. The new genus names and some of the new combinations are here formalized.

Synopsis of Plazia Ruiz & Pav. (Onoserideae, Asteraceae), including a new species from northern Peru

PhytoKeys (2014)

Michael O. Dillon Federico Luebert

A synopsis of Plazia Ruiz & Pav. (Onoserideae, Asteraceae) is presented, including the description of a new species, Plazia robinsonii M.O.Dillon & Sagást., from a locality c. 20 km west of Huamachuco, Department of La Libertad in northern Peru. It most closely resembles P. conferta Ruiz & Pav., a narrow endemic from central Peru some 450 km to the south; however, the latter species has larger leaves and smaller capitula. Plazia is a small genus of four species confined to the Andean Cordillera of Peru, Bolivia, Chile, and Argentina. A distribution map of the four species, an illustration of the new species, a photograph of the holotype, and a key to species are provided.

Choice of molecular marker influences spatial patterns of phylogenetic diversity

Biology Letters (2024)

Federico Luebert Rosa A. Scherson

Spatial patterns of phylogenetic diversity (PD) are increasingly becoming relevant for conservation decisions. PD measures are based on phylogenies estimated from molecular data. This paper addresses the question of how different molecular markers impact PD spatial patterns. We first conducted a simple simulation to explore the effect of deep and shallow changes in topology (simulating variations in molecular markers), using ultrametric and non-ultrametric trees, and then used a dataset of Chilean flora with four sets of markers to assess potential differences in spatial patterns of PD ranks using different markers and types of trees. The simulation consistently showed that the difference in PD rank was lower for ultrametric trees than for phylograms. A similar trend was observed using the Chilean flora dataset, with among-markers variability in spatial patterns of the PD metrics lower for ultrametric than for non-ultrametric trees, depicted as top 2.5 and 5% hotspots. Frequency distribution of PD values differed among markers as well, with this variation less apparent for ultrametric trees. We conclude that the choice of markers impacts spatial patterns of PD, and these results vary more strongly for phylograms, suggesting that ultrametric trees are more robust to the choice of marker.

Antioxidant Activity of a New Aromatic Geranyl Derivative of the Resinous Exudates from Heliotropium glutinosum Phil.

Molecules (2007)

Brenda Modak Macarena Rojas‐Poblete René Torres Jesús M. Rodilla Federico Luebert

Heliotropium glutinosum Phil. (Heliotropiceae) is a resinous bush that grows at a height of 2000 m in Chañaral, Chile. From the resinous exudates of Heliotropium glutinosum Phil. a new aromatic geranyl derivative: 4-methoxy-3-[(2)-7’-methyl-3’-hydroxymethyl-2’,6’-octadienyl] phenol (1) and three flavonoids: 5,3'-dihydroxy-7,4'-dimethoxyflavanone (2), 5,4'-dihydroxy-7-methoxyflavanone (3) and 4'-acetyl-5-hydroxy-7-methoxyflavanone (4) were isolated and their structures were determined. Their antioxidant activity were evaluated using the bleaching of ABTS and DPPH derived cation radical methods and expressed in terms of FRE (fast reacting equivalents) and TRE (total reacting equivalents), where FRE is a good measure of the quick protection of a given compound against oxidants and TRE measures the degree of long-term protection of the antioxidant, or how effective it is against a strong oxidative stress.

Phylogenetic relationships and generic reassessment of Proustia and allies (Compositae: Nassauvieae)

Taxon (2018)

Gisela Sancho Liliana Katinas Jessica Noelia Viera Barreto Andrés Moreira‐Muñoz Federico Luebert

Abstract Proustia is a small southern Andean genus of shrubs, vines and small trees, which are characteristic elements of Chilean and Argentine Andean forests, thickets and desert scrubs. Since Proustia possesses an unusual and characteristic morphology within the Nassauvieae, its circumscription as well as its phylogenetic placement is decisive in understanding the evolution of the tribe. Berylsimpsonia , from the Caribbean, was segregated from Proustia , which currently only includes three species. Lophopappus , another Andean genus, has been closely related to Proustia in sharing style and corolla features that are unusual in the Nassauvieae. The purpose of this work is to evaluate the placement of Proustia within the Nassauvieae, its relationships with Berylsimpsonia and Lophopappus , and the relationships of its species using molecular data and phylogenetic methods. This is the first comprehensive analysis of Proustia. We have included in our study the three currently accepted species of Proustia and seven of its ten infraspecific taxa. For each taxon of Proustia , one to seven accessions were analyzed. Species of Lophopappus and Berylsimpsonia , as well as 16 species belonging to 13 genera of Nassauvieae were also analyzed. We sequenced the nuclear ribosomal ITS and ETS, and the plastid regions ndhF , 5’ trnK–matK, trnL–trnF , and trnL(UAG)–rpl32. Unlike other previous studies, Proustia is not sister to the rest but nested in the tribe in our analyses. Berylsimpsonia vanillosma and P. ilicifolia are distantly related to P. pyrifolia , the type of the genus. According to nuclear DNA data, the infraspecific taxa of P. cuneifolia were recovered all in a well–supported clade, although based on the plastid data P. pyrifolia does not form a lineage separate from P. cuneifolia. Lophopappus is the genus most closely related to Proustia. Regarding the evolution of styles, our results suggest multiple origins of atypical stylar features in the Nassauvieae. As a result of our analyses we propose the segregation of Proustia ilicifolia into the new genus Spinoliva. Morphological data are consistent with the segregation of Proustia and Lophopappus as separate genera. Two species of Proustia, P. cuneifolia and P. pyrifolia are recognized. Three lectotypifications, one neotypification, two new combinations and five rank changes are proposed.
