gall
The nematodes generally live in the closed flower and leaves buds, only rarely endoparasitically. The leaves are disfigured, contorted; the veins are thickened, cartilaginous; sometimes numerous, short sprouts are formed. Buds may die off. Because the leaf tissue between the veins withers, a characteristic mosaic pattern results.
