FIGURE 6 in A new species of climbing Chamaedorea (Arecaceae) from Chiapas, Mexico
FIGURE 6. Parsimony haplotype network showing the relationships among species of the Elatior clade of the genus Chamaedorea. The network includes species for which the DNA sequences of the two loci, PRK and RPB2, were available. Most species, including C. elatior and C. tacanensis, are directly derived from an unsampled or extinct putative common ancestor (circle in the middle of the net). Black dots indicate non-sampled haplotypes.
FIGURE 1 in A new species of climbing Chamaedorea (Arecaceae) from Chiapas, Mexico
FIGURE 1. Distribution of climbing Chamaedorea species. Black dots represent localities of C. elatior sensu lato recorded in the Global Biodiversity Information Facility (GBIF, 2021). Two populations of the putative new climbing species described here as C. tacanensis has been recorded in one locality in Tacaná Volcano (locality #1), and one population has been recorded in San Marcos, Guatemala (locality #2). Localities #3–5 indicate C. elatior localities that were represented in the morphological and genetic analyses in this study. Green scale indicates elevation in meters above sea level (m a.s.l.) as recorded in the raster layers of 30-sec resolution of the NASA Shuttle Radar Topographic Mission (SRTM) 90m Digital Elevation Database v4.1 deposited in DIVA-GIS (https://www.diva-gis.org/. Base map was constructed in QGIS v3.16.18 (https://www.qgis.org).
FIGURE 5 in A new species of climbing Chamaedorea (Arecaceae) from Chiapas, Mexico
FIGURE 5. Cladogram showing the phylogenetic relationships among Chamaedorea species. The cladogram includes species for which the DNA sequences of the two loci, PRK and RPB2, were available. The focus species, C. elatior and C. tacanensis, form separate monophyletic groups, suggesting species delimitation. Together with several closely related species, C. elatior and C. tacanensis constitute the Elatior clade. C. elatior accessions with labels including "LB" indicate provenance from El Ocote, Chiapas, Mexico; "LP" indicate provenance from San Francisco La Paz, Santa María Chimalapa, Oaxaca, Mexico. Support above branches denote posterior probabilities. Two outgroup (OG) species were used to identify the polarity of the topology within Chamaedorea.
