The tribe Plantagineae (Lamiales) is a group of plants with worldwide distribution, notorious for its complicated taxonomy, still unresolved natural history, and a trend of morphologic reduction and simplification. This tribe includes the plantains (Plantago), the small aquatic Littorella, and the northern Andean shrubs Aragoa. Some Plantago lineages exhibit remarkably high diversification rates, which further adds to the complicated classification, and the worldwide distribution of these plants raises numerous questions related to vicariance and dispersal. In this work, we present the broadest phylogeny of the group to date and discuss the evolutionary, morphological, and biogeographical implications of our phylogenetic results, including the description of two new species from the Americas.

“…Rarity in this genus is common at a continental scale, most particularly on peripheral distribution areas such as oceanic islands and climatic transitional limits/boundaries (e.g., Dunbar-Co et al, 2009;Hassemer and Rønsted, 2016;Hassemer et al, 2018;Hassemer, 2019). Considering that the reunion of P. almogravensis and P. algarbiensis (after Pedrol, 2009) might have repercussions regarding the level of protection given to both taxa (being allopatric by more than 75 km, the Extent of Occurrence will increase, thus diminishing the perceived extinction risk), the addition of other diagnostic criteria regarding their population ecology and molecular phylogeny, besides revisiting the morphological comparisons already published, would give a stronger support to the conservation of both these taxa and of P. almogravensis in particular.…”

Reviewing the ecological studies on the endangered endemic Plantago almogravensis Franco, an Al-hyperaccumulator plant, and combining these with morphological, physiological, biochemical, and molecular data, significant knowledge on the limiting factors that cause its narrow geographical distribution and rarity status is achieved, which can contribute to suited conservation guidelines. Emphasis was given on (i) the major factors limiting P. almogravensis’ ecological niche (biotic and abiotic); (ii) phases of the life cycle and population dynamics; and (iii) and the phylogenetically close taxa (Plantago subulata aggregate) in order to fill the knowledge gaps in the uniqueness of P. almogravensis ecology, its phylogeny, and conservation status. The identification of relevant ecological data and using plant functional (morphological and physiological) traits, as well as genetic attributes, substantiate into a powerful tool to guide protection and conservation measures, usable toward this and other endangered hyperaccumulator plant species. Knowledge of the limitations of this strongly narrowly distributed plant allows for better design of conservation measures and to guide value and investment strategies in order to secure the species’ current area (habitat conservation and reclamation), direct the expansion of the existing population (assisting in populational densification and colonization), and/or grant ex situ conservation (genetic resources conservation).

“…Within this section, perhaps the most challenging group of species is the P. commersoniana Decne. & Barnéoud alliance ( Hassemer, 2019 ). This species alliance is distributed in Bolivia, Paraguay, Uruguay, northeastern Argentina, central Mexico and southern, eastern and central Brazil ( Rahn, 1974 ; Hassemer, 2019 ), and is characterised mainly by trichome characters, which are very important for the classification of Plantago ( Rahn, 1992 ).…”

This group includes the following currently-accepted species: P. berroi Pilg., P. bradei Pilg., P. commersoniana , P. floccosa Decne., P. guilleminiana Decne., P. hatschbachiana Hassemer, P. pyrophila Villarroel & J.R.I.Wood, P. rahniana Hassemer & R.Trevis., P. veadeirensis Hassemer and P. weddelliana Decne.…”

High-throughput sequencing, when combined with taxonomic expertise, is a powerful tool to refine and advance taxonomic classification, including at the species level. In the present work, a new species, Plantago campestris, is described out of the P. commersoniana species complex, based on phylogenomic and morphological evidence. The main morphological characters that distinguish the new species from P. commersoniana are the glabrous posterior sepals and the slightly broader leaves. The new species is known from only three localities, all in natural high-elevation grasslands in Paraná and Santa Catarina states, southern Brazil. According to the IUCN criteria new species should be assessed as Endangered (EN). We present field photographs of P. campestris and related species, and we provide an identification key to the species previously included within the circumscription of P. commersoniana.
