From J. D. Hooker 2 [March] 1846
Summary
Thanks for Edward Forbes’s letter. Botanical evidence conflicts with parts of his theory but supports others. Is becoming more of a migrationist.
Bentham agrees with JDH on polymorphism.

From J. D. Hooker [25 March 1846]
Summary
JDH recognises the existence of "altered states" of continental species in island floras. The botanists’ difficulty in determining a new species is no grounds for dismissing the important question of altered forms.
Will look for Ascension plants for Ehrenberg.
French Galapagos collections confirm JDH’s view that plants arrived from north.
Cannot agree with Forbes on North Atlantic flora.
Botanical definition of "highness" and "lowness" usually means complexity and simplicity.
Some plants, such as aquatic ones, are cleistogamous. Cannot see why they should not be.
