Notes.
Phyllagathis calisaurea was described, based on specimens collected in western Guangxi, China ( Chen 1984b). Subsequent authors did not recognise it as a distinct species and synonymised it within P. ovalifolia ( Hansen 1992; Chen and Renner 2007). Phyllagathis calisaurea and P. ovalifolia have adjacent distribution ranges (Guangxi vs. Yunnan, China). They are morphologically quite similar, with the only differences being leaf size (6.5-11.5 × 2-3.7 cm vs. 9-18 × 3-8.5 cm), leaf shape (ovate lanceolate vs. ovate to elliptic) and indumentum of the stems and leaves. Nonetheless, they failed to form a monophyletic group in both the previous ( Zhou et al. 2022) and current phylogenetic analyses (Fig. 1 View Figure 1 ). As only one accession of P. ovalifolia was included in these analyses, the boundary between P. ovalifolia and P. calisaurea needs to be further investigated using multiple accessions from across the distribution range. For the time being, we adhere to the species delimitation proposed by Hansen (1992) and Chen and Renner (2007).
