Summary

Botanical evidence is against F. B. White’s origin of St Helena fauna. JDH holds flora is S. African. Since plants must arrive before insects, if fauna is Palearctic then flora survived glacial period. Flora not Miocene since old and relic orders are absent. Suggests S. African west coastal mountains as insects’ origin.

To Asa Gray   2 May [1856]

Summary

Suggests affinities of the U. S. flora that he considers would be worth investigating. Wants to know the ranges of species in large and small genera.

Questions AG on naturalised plants; whether any are social in U. S. which are not so elsewhere and how variable they are compared with indigenous species. Would like to know of any differences in the variability of species at different points of their ranges and also the physical states of plants at the extremes of their ranges.
