My dear Sir

I have found a field here abounding in the common Genista tinctoria in full blossom & on examination of the opening buds; it appears that the keel & wings, have the same peculiarity of curling backwards by their claws on being touched as the Indigo which was growing in your Green-house; though in that instance the claws of the Alæ do not curl but only the keel.

I think of making a note of the fact, for the Linnean,¹ & should much like,—if you will kindly permit me—as you did before with reference to the structure of Broom—to describe the peculiar process of the French bean, to which you called my attention when I saw you.²

Of course I am presuming it has not been described; if it has, there would be no need to do it again.

Trusting your health improves | believe me | My dear Sir | to be ever faithfully yours | George Henslow
