Nabokovilia: Jeffrey Eugenides' The Marriage Plot

From Jeffrey Eugenides' The Marriage Plot:
"Bellovian," Leonard said. "It's extra nice when they change the spelling slightly. Nabokovian already has the v. So does Chekhovian. The Russians have it made. Tolstoyan! That guy was an adjective waiting to happen." (p. 57)
Possible second bit of Nabokovilia (the gesticulating trees echo Signs and Symbols -- relevant passage below the fold):

A three-thirty, instead of showing up for J.V. football practice, Leonard went straight home. A sense of impending doom, of universal malevolence, pursued him the entire way. Tree limbs gesticulated menacingly in his peripheral vision. Telephone lines sagged like pythons between the poles. When he looked up at the sky, however, he was surprised to find that it was cloudless. No storm. Clear weather, the sun pouring down. He decided that there was something wrong with his eyes. (p. 258)
From Nabokov's Signs and Symbols

...The patient imagines that everything happening around him is a veiled reference to his personality and existence. He excludes real people from the conspiracy, because he considers himself to be so much more intelligent than other men. Phenomenal nature shadows him wherever he goes. Clouds in the staring sky transmit to each other, by means of slow signs, incredibly detailed information regarding him. His in- most thoughts are discussed at nightfall, in manual alphabet, by darkly gesticulating trees.
