Koyamasia and Struchium (Asteraceae, Vernonieae), Two Newly Recorded Genera for China
Two suspicious species of Asteraceae tribe Vernonieae were discovered in Hainan Province, China. Detailed morphological investigation suggests that they are Koyamasia curtisii and Struchium sparganophorum. Molecular data based on nrDNA ITS sequence provide further support of the status of K. curtisii. These two species represented two genera that have not been reported from China. Therefore, they are two newly recorded genera for China.
