(a) Normal flowers (with five petals) of Styrax japonicus (Niiza, Japan; 6 May 2009). (b) A “gall shoot” that has sprouted from an axillary bud of S. japonicus, with a young gall of Ceratovacuna nekoashi at the apex, two bract-like leaves, and a new axillary bud at the base (Niiza; 6 May 2009). (c) A gall of C. nekoashi and an abnormal flower (with more than five petals) of S. japonicus (Niiza; June 1999). (d) The same abnormal flower shown from a different angle, indicating that it has sprouted from an axillary bud; petioles of abnormal flowers are variable in length and at times also with bracts (which are absent on this gall-flower shoot).
