“…as the northern Andes (27 spp., plus ca. 10 occurring in both regions; Santamaría-Aguilar and Monro, 2019). While northern Andean species cover a broad range of climate regimes, consistent with this region being one of the most climatically variable regions globally (Rahbek et al 2019), most central Andean species are clustered either in cooler, more-seasonal areas or warmer, more-seasonal climates (Fig.…”

“…Duplicate localities and country centroids were removed from the extracted data. Because Freziera has received a recent taxonomic revision (Santamaría-Aguilar and Monro 2019), data were not available for all species through GBIF; for these recently described species, locality data were gathered from Santamaría-Aguilar and Monro (2019; F. golondrinensis , F. monteagudoi , F. peruana , and F. siraensis ) and Cuello and Santamaría-Aguilar (2015; F. guaramacalana ). Where applicable, points were also removed from the species to which these specimens were previously assigned.…”

“…), but range in elevation within the mid-elevation, moist forest biome (Weitzman 1987(Weitzman , 1988Santamaría-Aguilar and Monro 2019). Unlike many charismatic cloud forest radiations, Freziera species are consistent in life history traits related to reproduction: species are dioecious (i.e., separate staminate (pollen producing) and pistillate (ovule producing) individuals), flowers exhibit a generalist invertebrate pollination syndrome (i.e., small, pale green to white flowers with a narrow opening for an insect proboscis), and all species produce fleshy berries as fruits (Weitzman 1987(Weitzman , 1988Weitzman et al 2004;Santamaría-Aguilar and Monro 2019). They do not have large, showy flowers or particularly variable morphology in flowers or fruit.…”

Strong phylogenetic signal despite high phylogenomic complexity in an Andean plant radiation (Freziera,Pentaphylacaceae)

The Andes mountains in South America are a biodiversity hotspot within a hotspot, the New World Tropics, for seed plants. Much of this diversity is concentrated at middle-elevations in cloud forests, yet the evolutionary patterns underlying this extraordinary diversity remain poorly understood. This is partially due to a paucity of resolved phylogenies for cloud forest plant lineages: the young age of the Andes and generally high diversification rates among Andean systems precludes robust phylogenetic inference, and remote populations, few genomic resources, and generally understudied organisms make acquiring high-quality data difficult. We present the first phylogeny of Freziera (Pentaphylacaceae), an Andean-centered, cloud forest radiation with potential to provide insight into some of the abiotic and extrinsic factors that promote the highest diversity observed on the globe. Our dataset, representing data for 50 of the ca. 75 spp. obtained almost entirely from herbarium specimens via hybrid-enriched target sequence capture with the universal bait set Angiosperms353, included a proportion of poorly assembled loci likely representing multi-copy genes, but with insufficient data to be flagged by paralog filters: cryptic paralogs. These cryptic paralogs likely result from limitations in data collection that are common in herbariomics combined with a history of genome duplication and are likely common in other plant phylogenomic datasets. Standard empirical metrics for identifying poor-quality genes, which typically focus on filtering for genes with high phylogenetic informativeness, failed to identify problematic loci in our dataset where strong but inaccurate signal was a greater problem. Filtering by bipartition support was the most successful method for selecting genes and resulted in a species tree with lower discordance, higher support, and a more accurate topology relative to a consensus tree. Using known paralogs, we investigate the utility of multi-copy genes in phylogenetic inference and find a role for paralogs in resolving deep nodes and major clades, though at the expense of gene tree concordance and support. With the first phylogeny, we infer the biogeographic history of Freziera and identify the northern Andes as a source region. We also identify distinct modes of diversification in the northern and central Andes, highlighting the importance of fine-scale biogeographic study in Andean cloud forest systems.

Despite a rich recent literature on new species and nomenclature (summarized in Santamaría-Aguilar & Monro 2019), the taxonomy of this genus, with c. 63 species in the Neotropics, is still poorly understood.

The genus Freziera Willd. is distributed in Venezuela along major mountain systems, including Los Andes, Coastal Cordillera, and Guayana Shield. Two out of 11 Freziera species known from Venezuela are endemic to this country and could be endangered, but their actual conservation status is unknown, being Data Deficient according to the criteria of the IUCN. In this work, a key for the Venezuelan species is provided for the first time, and Freziera polita A.L.Weitzman ex J.R. Grande, sp. nov., from Cordillera de Mérida, is described and illustrated. Diagnostic characters of the new species, which is most closely similar to F. Guaramacalana D.Santam. & Cuello, include elongated petioles, subglabrous mature leaves, and corollas (at anthesis) that are exerted less than half the length of sepals.
