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.

DAR 104: 188–91
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.

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