Summary

Goes on the assumption that each species has one origin, is immutable, and migrates.

Disagrees with Gaudichaud[-Beaupré] that volcanic island species are polymorphous.

Some mundane genera vary, others do not (Senecio vs Gnaphalium).

John Lindley’s doctrine of longevity of trees is amazing.

Edward Forbes’s health is better.

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.

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.

Summary

Hugh Falconer gives no specific objections to Forbes’s views.

Botanical contrast between Cape of Good Hope and the rest of Africa is as strong as that between Australia and India.

Wishes CD would leave off snuff.

Summary

Cannot come to Down to meet B. J. Sulivan as W. H. Harvey is calling.

Plant distribution and soil nature.

Forbes’s modification of Watson’s types of vegetation.

JDH will write comparison of representative plant species of the N. and S. Hemispheres.
