Lagerstroemia stenophylla, a new species from southeastern Shaanxi Province and northwestern Hubei Province of China is described. Morphologically, L. stenophylla resembles L. subcostata, but it differs in having 4-angular, subalate branchlets, elliptic-lanceolate, or narrowly elliptic leaves, and relatively larger flowers.

A new species of the genus Camellia (Theaceae), Camellia shuangbaiensis G.P.Yang & B.H.Wu, sp. nov., from the central region of Yunnan Province of China is described. Camellia shuangbaiensis is morphologically similar to C. mileensis and C. hongkongensis, but it can be distinguished by its smaller leaves with an ovate, abaxially tomentose lamina, and 14–16 bracteoles and sepals.

A new species from southern China, Lagerstroemia yangchunensis B.H.Wu & G.D.Chen, sp. nov., is described in the present paper. This species is morphologically similar to L. duperreana Pierre ex Gagnep., but can be distinguished by its coarse bark with vertical fissures, calyx lobes glabrous inside, and flowers with shorter pseudopedicels and petals with longer claws. Detailed morphological characteristics, habitat information, and comparisons with similar species are provided.

The original specimens of both Prunus zappeyana and P. zappeyana var. subsimplex were found to belong to more than one taxon. In addition, P. zappeyana var. subsimplex was found to be invalid because, when the name was published, two separate descriptions were given to two cited collections, but not to the taxon, making the name unaccompanied with a description or diagnosis of this taxon (Art. 38.1 (a)). Therefore, a lectotype of P. zappeyana was designated under Art. 9.11 of ICN, by which P. zappeyana was placed in the synonymy of P. veitchii.
