“…In Proustia and Lophopappus, these unusual corollas are not always symmetrically 5-lobed, with all the lobes similar in length, but irregularly 5-lobed, showing different stages and forming a continuum between bilabiate and 5-lobed corollas (Crisci, 1974;Katinas & al., 2013;Sancho & al. 2014) (Fig.…”

“…Intergeneric relationships of Proustia are no less problematic. Lophopappus Rusby, an Andean genus of five species (Katinas & al., 2013) has been closely related to Proustia, mainly by sharing style, corolla, and pollen features (Crisci, 1974;Tellería & al., 2003;Katinas & al., 2013;Sancho & al., 2014). Figures 1A-P and U-Y show some of their distinctive features.…”

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.

“…Eventos de especiación condujeron a algunas especies a ocupar sitios más secos en la vertiente occidental de la Cordillera desde el centro de Perú hacia el extremo norte de Chile. También las especies de Lophopappus tienen una ocurrencia en las partes secas de las provincias Altoandina y de la Puna en Perú (Montecinos-Tubée et al 2015) aunque algunas especies ocurren también en bosques pluviosos (Katinas et al 2013). Por otro lado, hay especies que provienen de grupos de distribución andina austral, como es el caso de Leucheria daucifolia, única especie de este género eminentemente chileno que alcanza el sur de Perú.…”

“…Para ello se requiere ir mejorando el conocimiento de la biodiversidad y sus usos actuales e históricos; y es importante que dicho conocimiento se sustente en una adecuada y actualizada taxonomía. Faúndez & Macaya (1998); sinonimia no aceptada por Katinas et al (2013), indicando que L. cuneatus posee sólo corolas bilabiadas, mientras que L. tarapacanus posee, además de corolas bilabiadas, corolas tubulosas infundibuliformes o tubulosas-bilabiadas, observados en un isotipo en LP (los ejemplares en SGO tienen capítulos inmaduros). Los ejemplares Tipo fueron los únicos citados por Katinas et al (2013) (2012), Perezia pinnatifida podría considerarse una forma no escaposa de Perezia pungens, pero dado que coinciden en las mismas áreas con idénticas condiciones ecológicas individuos con escapos largos, y otros con escapos muy cortos, dicha autora considera a P. pinnatifida y a P. pungens como especies independientes.…”

RESUMENLa familia de las Asteráceas o Compuestas es la más diversa de la flora de Chile, sin embargo, sólo algunas tribus han sido sometidas a un tratamiento sistemático reciente, mientras que el conocimiento de la distribución geográfica de los taxones es aún muy deficiente. A partir de la revisión de ejemplares de herbario y trabajo de campo, se realizó una prospección de la flora de Asteráceas de la Región de Arica y Parinacota. Ello da como resultado la presencia de 144 taxones en la región, de los cuales un 82,6% es nativo (119) y un 9% es endémico (13) de Chile, mientras que el 8,3% restante corresponde a especies alóctonas o naturalizadas (12). El género Senecio es el más diverso en la región con 27 especies nativas, incluyendo seis especies endémicas de Chile. Se constató la presencia de cinco especies nuevas para la flora de Chile: Achyrocline ramosissima Britton, Gamochaeta humilis Wedd., Mniodes kunthiana (DC.) S.E. Freire et al. (=Lucilia violacea Wedd.), Pseudogynoxys cordifolia (Cass.) Cabrera y Senecio evacoides Sch. Bip. Sobre la base de los materiales recolectados, se ha publicado recientemente la nueva especie Pseudognaphalium munoziae N. Bayón, C. Monti & S.E. Freire. Adicionalmente, se ha revisado la correcta denominación de la especie endémica Stevia philippiana. La mayor diversidad de especies se encuentra en la provincia de Parinacota, sobre los 3.000 m s.n.m. Las Asteráceas no sólo destacan en la región por su diversidad, sino también por constituir un elemento esencial de la vegetación, especialmente de las unidades vegetacionales de precordillera y altiplano, denominadas genéricamente como "tolar". La mayor parte de los pisos de vegetación de la provincia de Parinacota poseen especies de Asteráceas como especies dominantes, especialmente de los géneros Parastrephia, Lophopappus, Baccharis y Senecio. Si bien la región posee un porcentaje importante de superficie bajo protección, varias de las especies estudiadas, especialmente de precordillera, quedan fuera del sistema de áreas protegidas.PALABRAS CLAVE: Flora de Chile, Catálogo florístico, Reserva de la Biosfera Lauca, conservación de la biodiversidad, especies endémicas. ABSTRACTThe family of the Asteraceae is the most diverse in the Chilean flora; nevertheless, only some tribes have undergone a recent systematic treatment, while the knowledge about the geographical distribution of the taxa is still very incomplete. From the review of herbarium specimens and fieldwork, a survey of the Compositae flora of the Arica y Parinacota Region was performed. The study shows the presence of 144 taxa of the Asteraceae family in the region of which 82.6% is native (119) and 9% is endemic to Chile (13), while 8.3% are considered as exotic species (12). The genus Senecio is the one showing the highest diversity in the region, with the presence of 27 species, including six endemic ones. The revision of the botanical material reveals the presence of five new species for the Chilean flora: Achyrocline ramosissima Britton, Gamochaeta humilis Wedd., Mnio...

Is morphology supporting a monophyletic Proustia Lag., (Nassauvieae, Asteraceae)?

Proustia is an Andean genus traditionally considered to have three species and ten infraspecific taxa, which has often been placed in tribes other than Nassauvieae mainly because of its distinctive style features. Currently, each of the three species of Proustia is included in its own section denoting a consistent morphological variability within the genus. The heterogeneity among Proustia species mainly relies on habit, spiny structures arrangement, capitula arrangement, and pappus features. On the contrary, the forms or varieties within each species are apparently more homogeneous. The phylogenetic analysis performed here is based on morphological features and includes all the species, and all but two varieties and forms of Proustia. We test the boundaries of Proustia and the hypothesis that morphological discontinuities in the genus are phylogenetically uninformative. A total of 26 taxa and 29 morphological, anatomical, and palynological characters were studied. A maximum parsimony analysis yield six most parsimonious trees that showed almost identical topologies. Our results do not support the current generic concept of Proustia. Independently, each species of Proustia was monophyletic when taxa at sub-specific level were considered. Proustia pyrifolia was retrieved sister to the genus Berylsimpsonia although this clade did not obtain significant support. The spiny structures usually referred to as diagnostic for Proustia are not homologous for the genus. Characteristics of habit, spiny structures, secondary inflorescences and pappus support clades representing each species of Proustia, which may in turn, represent different genera.
