“…Fewer species inhabit the evergreen rain forest or the cloud forest. They are found growing from sea level up to 2700 m in altitude (Espejo-Serna & López-Ferrari, 1998;Ramírez-Morillo et al, 2018a, 2018b.…”

“…In the latest comprehensive revision of the family, Smith & Downs (1974) recognized a single genus, Hechtia Klotzsch, which was subsequently treated as a subfamily by Givnish et al (2007). Recently, Ramírez-Morillo et al (2018a, 2018b have carried out the first comprehensive phylogenetic analysis of the subfamily, based on plastid and nuclear DNA sequences, and morphological characters; as a result, they proposed a new classification of the subfamily, where three genera are recognized: Hechtia, Bakerantha L.B. Sm., and Mesoamerantha I. Ramírez & K. Romero.…”

“…The species of this genus are endemic to the central region of Mexico, with very restricted distributions. The genus includes lithophytic herbs that grow in several types of ecosystems, ranging from tropical dry forests and xerophilous scrubs to evergreen rain forest and cloud forests, at elevations of 130-1800 m in the Balsas Basin, Chihuahuan Desert, Sierra Madre Oriental, Trans-Mexican Volcanic Belt (TMVB), and Veracruzan biogeographic provinces (López-Ferrari et al, 2010;Ramírez-Morillo et al, 2018a, 2018b. et al, 2020).…”

Bakerantha is one of the three genera of subfamily Hechtioideae (Bromeliaceae). This genus was reestablished recently, and it currently contains four species (B. caerulea, B. lundelliorum, B. purpusii, and B. tillandsioides), which are distributed throughout the central region of Mexico. Bakerantha tillandsioides has the widest geographical distribution of the four species, and some populations currently referred to it do not match the species description. In this study, we used extensive sampling (81 accessions) of four plastid regions (matK, rpl32-trnL, rps16-trnK, and ycf1) and the nuclear PRK gene to reconstruct the phylogenetic relationships and delimit the species boundaries in Bakerantha. Our results confirm the monophyly of Bakerantha, and the species delimitation analysis supports five evolutionary lineages within Bakerantha, showing that B. tillandsioides is nonmonophyletic as currently circumscribed. Diagnostic characters and coherent geographical distributions support the five lineages. On the basis of our results, we describe and illustrate B. hidalguense as a new species and provide evidence that B. caerulea is morphologically and ecologically different from B. tillandsioides, with which it has been confused in the past. Additionally, we provide a morphological key to the Bakerantha species.

“…Hechtia argentea is in the unresolved Hechtia glomerata clade (Ramírez‐Morillo & al., 2018a). As mentioned above, H. argentea was not included in a phylogenetic analysis (Ramírez‐Morillo & al., 2018b), but it shares some morphological features with species in the clade, particularly with the sympatric H. glomerata , but the rosettes are distinguished by the white, dense pubescence on both sides of the leaves, even from small size (Fig. 7B) and at distance could be identified due to these silvery‐colored leaves (Fig.…”

“…Although not included in the only phylogenetic study based on morphological and molecular characters of Hechtioideae (Ramírez‐Morillo & al., 2018b), Hechtia argentea shares several characters with species in the Hechtia glomerata clade, i.e., polycarpic rosettes and lateral inflorescences, those both covered by a white indumentum, and both sexes exhibit white flowers (except for H. pretiosa Espejo & López‐Ferr. having pink to magenta petals).…”

Hechtia argentea was described from a cultivated pistillate plant of unknown origin. The type specimen consists of a leaf fragment and a portion of a pistillate inflorescence. Hechtia argentea is part of a group of species with rosettes that bloom laterally, showing variation in dimensions and structure of the inflorescences of both sexes through the different years of flowering. Delimitation of species becomes more complicated where staminate and/or pistillate plants of different species are frequently similar, making it essential to have all plant structures available for accurate identifications. We designate an epitype for Hechtia argentea, consisting of a staminate plant, allowing for the unambiguous identification of the species. Species in Hechtia have restricted geographical distributions; thus, we provide precise locality data for H. argentea within Megamexico based on herbarium specimens. The species is endemic to the Sierra Madre Oriental and Mexican Plateau biogeographical regions, in the Mexican States of Hidalgo and Querétaro. In addition, we include for the first time a complete morphological description of both morphs, line drawings and photos of the species in situ, as well as a map showing the known distribution. Finally, we present an evaluation of the risk of extinction following the IUCN criteria.

The diverse diaspora of CAM: a pole-to-pole sketch

Background CAM photosynthesis is a successful adaptation that has evolved often in angiosperms, gymnosperms, ferns and lycophytes. Present in ca. 5 % of vascular plants, the CAM diaspora includes all continents barring Antarctica. Species with CAM inhabit most landscapes colonized by vascular plants, from the Arctic Circle to Tierra del Fuego, from below sea-level to 4,800 m, from rainforests to deserts. They have colonised terrestrial, epiphytic, lithophytic, palustrine and aquatic systems developing perennial, annual or geophyte strategies that may be structurally arborescent, shrub, forb, cladode, epiphyte, vine or leafless with photosynthetic roots. CAM may enhance survival by conserving water, trapping carbon, reducing carbon loss and/or via photoprotection. Scope This review assesses the phylogenetic diversity and historical biogeography of selected lineages with CAM viz. ferns, gymnosperms and eumagnoliids, Orchidaceae, Bromeliaceae, Crassulaceae, Euphorbiaceae, Aizoaceae, Portulacineae (Montiaceae, Basellaceae, Halophytaceae, Didiereaceae, Talinaceae, Portulacaceae, Anacampserotaceae, Cactaceae) and aquatics. Conclusions Most extant CAM lineages diversified since the Oligocene/Miocene as the planet dried and CO2 concentrations dropped. Radiations exploited changing ecological landscapes including Andean emergence, Panamanian Isthmus closure, Sundaland emergence and submergence, changing climates and desertification. Evidence remains sparse for or against theories that CAM-biochemistry tends to evolve prior to pronounced changes in anatomy, and that CAM tends to be a culminating xerophytic trait. In perennial taxa, any form of CAM may occur depending upon the lineage and the habitat, although facultative CAM appears uncommon in epiphytes. CAM annuals lack strong CAM. In CAM annuals, C3+CAM predominates and inducible- or facultative- CAM are common.
