SUMMARY The distribution of flower galls caused by Anguina amsinckiae (Steiner & Scott, 1934) Thorne, 1961 on the host plant Amsinckia intermedia Fischer & Meyer (Borraginaceae) is described. Galls were exclusively associated with floral tissues, and were restricted to the five uppermost inflorescences of the host plants. Approximately 93 O’o of total galls were located in the two uppermost inflorescences. Within a given inflorescence, galls were restiicted to the six basal flowers with approximately 82 O/O of the galls being distributed between the most basal flower and the flower directly above it. This gall distribution suggests that nematode attack occurs during the host’s early flowering stages, and that the pattern observed may be a function of moisture availability to the nematode during infection. Plant growth regulators are suggested as a possible means of enhancing the onset and degree of galling.
