<\/p>\n

\n

4a<\/strong> On shoot tips, buds or leaves => 5<\/p>\n

4b<\/strong> Stem with expanded spindle-shaped swellings, the pith containing a caterpillar. G. fastigiata, paniculate: Caryocolum leucomelanella<\/a><\/em><\/p>\n<\/div>\n

\n

8a<\/strong> Shoot tips or lateral buds stunted. Leaves transformed into a hemispherical to onion-shaped, often reddened gall. Occasionally enveloped by a spreading, basally strongly swollen \u00b1 fully developed pair of leaves; also may develop \u00b1 stunted leaf blades only at the base of galled leaves.
