List of most anomalous Leguminosae [from George Bentham].
Discusses the transport of seeds by birds. William Thompson received letters on this subject from CD in 1848 and from Edward Forbes in 1850. Encloses copies of Thompson’s reply to Forbes’s letter of 23 Feb 1850 and of Thompson’s notes (1848–51) on transport of seeds by birds.
JDH’s "grand speech" on receiving the Royal Medal.
Is Bentham’s list of aberrant genera biased by exclusion of genera with many species?
JDH’s belief that Aquilegia varieties are one species is consistent with their great interfertility.
Thanks for Lady Holland’s kind present. Will only lend it to his sister-in-law and his aunt.
Bentham’s list of aberrant genera: CD’s worry that he eliminated large genera a priori is half right. He eliminated those large, anomalous genera that virtually constitute natural orders. JDH criticises CD’s tabulations of aberrants.
Difficulty of distinguishing affinity and analogy in plants.
Debates aberrant species, e.g., Ornithorhynchus and Echidna, with JDH. CD argues they are result of extinction having removed intermediate links to allied forms.
Studying effects of disuse in wings of tame and wild ducks.
Tabulations showing that number of species in a genus is not correlated with number of genera in an order.
