To J. D. Hooker 16 [May 1857]
Summary
Asks JDH’s opinion, and botanical evidence, on important law: parts that are highly developed in comparison to other allied species are very variable.
Interest in hairiness of alpine plants revived by reading A. Moquin-Tandon [Éléments de tératologie végétale (1841)]; correlation with dryness. CD seeks interpretation independent of direct environmental effect.
