From Daniel Oliver   [17 March 1864]1

Thursdy. morng.

I have been looking at several species of Tecoma this morning. Trained up walls & iron girders or rafters they are more peculiarly unfavourable conditions for exhibition of climbing idiosyncrasies!—

T. capensis exhibits no rootlets nor do I see any indication of twining. It wd. seem to be a scrambler! T. undulata— I think I saw but a young plant. I doubt if it shew any twisting or climbing.—

T. jasminoides & T. Latrobei I find tips of branches spirally twisted—2 I put them in herewith.— T. Latrobei is the small-leaved one

Yours very sincerely D. O.

I wrote you about axis & leaf a few days ago.3 I have been thinking that I shd perhaps apologise for a letter which might have been more seemly if addressed to one of my students—but from the way in which the enquiry was put I thought there was indication of doubt upon one or two matters which routinists regard in the light of axioms.

The date is established by the relationship between this letter and the letter to Daniel Oliver, 11 March [1864]. In 1864, the Thursday following 11 March fell on March 17.
CD had asked about the climbing movements of several species of Tecoma in his letter of 11 March [1864]. Though there is a note recording observations of T. jasminoides in DAR 157.1: 45, the only Tecoma species CD mentions in ‘Climbing plants’ is T. radicans (pp. 25, 106, 114); he found that it climbed by its rootlets, and suspected that slight movements of its shoots were an indication that it had once been a twining plant. See CD’s notes on T. radicans in DAR 157.1: 59–60.
