Abstract: Two new species of the genus Yulania Spach of Magnoliaceae were described from Sichuan province of China. They are Yulania carnosa D. L. Fu et D. L. Zhang, sp. nov. and Y.shizhenii D. L. Fu et F. W. Li, sp. nov.. The main distinguishing features are that Y.carnosa has two spathacei-bracts on a flower, one membranous inserted in the middle of the pedicel and the other carnose inserted at the top of the pedicel. The tepals, the stamens, and the styles and stigmas of pistils of Y.shizhenii all are lily and there are only about 20 stamens. The species were found and collected in March, 2001 in Sichuan Province of China by Da-Li Fu. The holotypes of two species are kept at Chinese Academy of Forestry (CAF), No.200103141(Y.carnosa) and No.200103161(Y.shizhenii).
