TAXONOMIC STUDIES OF ALTERNARIA FROM CHINA IV. NEWSPECIES AND NEW VARIETIES ON APOCYNACEAE ANDCARICACEAE

Three new species, two new varieties of Alternaria are reposed. They are Alternariatrachelospermi T. Y. Zhang, X. F. Lin et W. Q. Chen, A. tenuissima (Nees ex Fr.) Wiltshire var.trachelospermicola T. Y. Zhang, X. E Lin et W. Q. Chen, A. tenuissima (Nees ex Fr.) Wiltshirevar. catharanthi T. Y. Zhang et X. F. Lin and A. catharanthicola T. Y. Zhang on plants ofApocynaceae, and A. caricae T. Y.
