Taxonomic study reveals Sinocrassula zhaotongensis as a novel succulent species, indicating a distinct lineage sister to Sinocrassula adpressa.
Key Points
To describe, illustrate, and determine the phylogenetic placement of Sinocrassula zhaotongensis, a newly identified succulent species.
Characterized morphology based on vegetative and floral traits including leaf shape, surface texture, sepals, and petals.
Performed phylogenetic analyses using concatenated chloroplast and nuclear DNA sequence data.
Sinocrassula zhaotongensis is characterized by a glabrous surface, asymmetrical triangular-to-lanceolate basal leaves, and triangular petals with dense purple-red stripes over a yellowish base.
Phylogenetic reconstruction strongly resolves the taxon as an independent evolutionary lineage sister to Sinocrassula adpressa.
