Abstract

Two newly naturalized plants, namely Hypochaeris albiflora (Kuntze)Azevêdo-Gonç. & Matzenb. (Asteraceae) and Solanum diphyllum Linn.(Solanaceae), were first recorded in mainland China. Hypochaeris albiflora is native to South America, and has become locally naturalized in Panlong District, Yunnan Province, Southwest China. In genus Hypochaeris, H. albiflora is characterized by its basal leaves entire or dentate, sometimes pinnately lobed to deeply lobed, cauline leaves linear, capitula cylindrical or narrowly campanulate, florets white and achene with four ribs. Solanum diphyllum is native to the Mexico and Central America, it is now found naturalized in Mengla County, Yunnan Province, Southwest China. S. diphyllum is a perennial evergreen shrub and characterized by its upper leaves usually arranged in pairs on each node and unequal in size, mature fruits yellow. In additon, the potential harm and invasive risks of these two naturalized plants are briefly assessed as well.
