We constantly discover references to the monster used as analogies for oddball biological creations. Hybrids and worse.
Here's this week's, from a syndicated Washington Post article about -- of all things -- an evergreen tree:
"The Leyland cypress (named after its 19th-century discoverer and champion, C. J. Leyland) might be likened to Frankenstein's monster. It is an unnatural creature, a weird cross between two entirely different evergreens, the Monterey cypress and the Alaskan cedar."
Fact is, cross-pollination and cross-grafting date back centuries. Our monster has botanical roots.
