To Asa Gray 9 May [1857]
Summary
Thanks for new part of "Statistics".
Interested in disjoined species; do they tend to belong to large or small genera, and are they generally members of small families?
Is glad AG will tackle introduced plants; has noticed that the proportion of a particular family to the whole flora tends to be similar in introduced and indigenous plants.
