From W. T. Thiselton-Dyer [21 October 1877]1
better to accept Mr Spottiswoode’s proposal to come in the afternoon2
Sir Joseph arrived on Friday looking extremely well.3 Harriet and I start tomorrow morning4 I wish we were going south instead of north. Sir Joseph mentioned to me an interesting fact which the American botanists communicated to him. The leaves of Pinus Nordmanniana are spread horizontally in the morning and rise in the day.5 As the under surfaces of the leaves are white—the facies of the tree gets altered. This is an interesting fact in a group so distinct as Gymnosperms Some coniferæ are dicotyledonous
