from Zheng X, Ho HH. 1998

Phytophthora polygoni Saw. was first discovered and described on the leaves of Polygonum japonicum Meisn. (Family Polygonaceae) in Taipei and Taichung of Taiwan causing leaf spot disease from the late winter/early spring to early summer (Sawada, 1922). The disease first appeared as small, round, yellow-green spots which became dull yellow-brown with a tint of purple. Subsequently, the lesions enlarged and turned brown and diffuse, resulting in the death of the lower leaves.
Unfortunately, type specimen of P. polygoni is no longer in existence for re-evaluation, and the fungus has not been reported again since its first description. Efforts were thus made to locate Polygonum and related genera within the family Polygonaceae, with the symptoms as described by Sawada, hoping that P. polygoni could be rediscovered.
