TABLE 1 in Nymphanthus adenophorus, a new species of Phyllanthaceae from Vietnam

TABLE 1. Morphological comparisons of Nymphanthus adenophorus with N. pireyi and N. nanellus. The characteristics of N. pireyi are based on Beille (1927) and Hô (2003), while those of N. nanellus are from Li (1987) and Li & Gilbert (2008). The length of floriferous branchlets, the number of leaves per floriferous branchlet, and the visibility of lateral veins on the leaf blades are also derived from digitized herbarium specimens listed in Appendix 1.
