i like michael g’s gloss on the robert byron nearly as much as i like the passage.
“Arboristirpal succession” is a pun on “apostolic succession,” from arbor, arbŏris = tree and stirps, stirpis = stem, stock, race, family, lineage. I also considered “arboristolonic,” from stŏlo, stolōnis = shoot, branch, twig, scion. “Arboristolic” would be a hybrid, from Latin and Greek roots (cf. apostolic, from ἀποστέλλω = dispatch on some mission or service).
