Abstract
The genus Lindernia (Scrophulariaceae) in Taiwan was taxonomically revised based on morphological and ecological studies. Thirteen species and 2 varieties of this genus, including a newly recorded species, L. nummularifolia (D. Don) Wettst. and a newly naturalized species, L. rotundifolia (L.) Alston are treated. Three species: L. hyssopioides (L.) Haines, L. mollis (Benth.) Wettst., and L. viatica (Kerr ex Barnett) Philcox are excluded from the flora of Taiwan. A key to sections and species is presented.
