TABLE 1 in Nymphanthus namkadingensis, a new species of Phyllanthaceae from Laos

TABLE 1. Morphological comparisons of Nymphanthus namkadingensis with N. chantaranothaii, N. glaucescens, and N. rubescens. The characteristics are derived from Beille (1927) and Pham (2003) (N. glaucescens & N. rubescens), Chantaranothai (2007), and Li & Gilbert (2008) (N. glaucescens), and Pornpongrungrueng et al. (2019) (N. chantaranothaii). Size of stipules of N. rubescens is measured on digitized herbarium specimens listed in Appendix 1.
