From J. D. Hooker [26 November – 4 December 1860]
Summary
Encourages CD’s work in vegetable physiology.
Ascending the Lebanon JDH noted limits of plant distribution as CD requested: lower limits of a genus sharper than upper. Sharpness of boundaries related to a plant’s moisture requirement.
Impressed by "sporadic" distribution at the Jardin des Plantes in Paris.
