| Abstract: | Some lettuce-like leaf vegetables called ambiguously "Womacai" are widely cultivated in the Three-Gorges Reservoir Area. A taxonomical study was made of these plants and their wild relatives. They were found to belong to the genera Lactuca and Pterocypsela . One species and 3 varieties of Lactuca and 5 species and 1 variety of Pterocypsela were found to be cultivated or to grow wildly in this area. One new species, P. lyrata, one new variety, L. sativa var. pinnata , and one newly classified combination, P. indica var. dentata , are first reported in this paper. |
