From W. H. Harvey   11 November 1864

4 Winton Road | Dublin

Nov. 11. 1864

Dear Darwin

I contrived to get to town today, and examined all my specimens alluded to in last note.1

I find that my ‘facts’ are only, to a great degree, correct; that is, while the majority of my sp. of the Ipomœa, collected from a great many localities widely separated—several far beyond the Colony—have straight, stiff stems—yet I have one from Howison’s Poort near Grahamstown,2 showing an evident disposition to twine.3 I suppose the locality is moister & more shady—but dont know.

The same of the Ceropegiæ—some of the taller ones show an inclination to curve—but by far the greater number are erect—& seem to have been stiff.—

This is all I can add to what I wrote last.

Yours very truly | W. H. Harvey
