Flora of Thailand, lectotypification, Piperales, taxonomy, tropical plants


We update the descriptions of seventeen native species of Peperomia in Thailand, including a new species, P. ranongensis, and a detailed morphological description for the uncommon species P. kotana based on Thai specimens. We provide a generic description, a key to all the species and provide lectotypifications for P. bavina, P. heyneana, P. laticaulis, P. nakaharae and P. reflexa var. parvifolia. Five species, P. heptaphylla, P. masuthoniana, P. multisurcula, P. ranongensis and P. sirindhorniana, are endemic to Thailand. Peperomia pellucida is a common pantropical species. Eight species, namely P. cavaleriei, P. dindygulensis, P. heyneana, P. laevifolia, P. masuthoniana, P. moulmeiniana, P. multisurcula and P. sirindhorniana have a high potential for development as ornamental plants.
