14/10/87.
In sending more proof of my poor "Key",1 dear Prof. Gray, you will see, that I had some misgivings in retaining the name Geranium Carolinianum, and thought it safer, to return to the original specific appellation of G. pilosum for the widely distributed Australian plant.2 Here it is never annual, simply perhaps, as we have no severe winter; but the exact position of several allied forms needs to be studied from American material; and altho' such is in my own collection, much through your generosity, and is also in Sonder's largely extant, it would be best, that American local experience ought to be brought to bear on the subject.
Perhaps one of your many disciples would institute researches in this direction.
Ever regardfully your
Ferd. von Mueller.
Can you kindly inform me, what is the exact position of the radicle of Sterculia Mexicana?
Geranium Carolinianum
Geranium pilosum
Sterculia Mexicana
