Jan. 19/78

My Dear Darwin

Though my crop of Drosera spathulata has grown so steadily the plants are all still D. rotundifolia1 I forgot to tell you that though my old p⁠⟨⁠  ⁠⟩⁠ seeded so freely, it n⁠⟨⁠ever⁠⟩⁠ opened its flowers. ⁠⟨⁠    ⁠⟩⁠ one solitary flower— on a long spike expanded its pink petals— In all the rest the tips of those unfolded petals alone shewed themselves beyond the un⁠⟨⁠op⁠⟩⁠ened sepals—yet each ovary was crammed full of fertile seeds—

Will you congratulate your son, for me, on ⁠⟨⁠hi⁠⟩⁠s magnificent demonstration ⁠⟨⁠that⁠⟩⁠ these plants, like mankind generally, flourish best on Beef & Mutton!2 His position appears to me to be unassailable

I hope to have the pleasure of shaking hands with you once more in a short time. Early in March my wife & I have promised to spend a Sunday with the Lubbocks wh⁠⟨⁠en⁠⟩⁠ I hope your health w⁠⟨⁠ill⁠⟩⁠ assume one of its be⁠⟨⁠tter⁠⟩⁠ conditions.3

I am ever y⁠⟨⁠ours⁠⟩⁠ | W. C. Wil⁠⟨⁠liamson⁠⟩⁠

Whenever the leaves of my Droseræ change into their “spathulate” condition I will take care to send you a plant or plants that you may watch their transition4

I have just received communication from Lesquereux. He has found in the Cincinnati Lower Silurians, true ⁠⟨⁠L⁠⟩⁠epidodendroid stemsSphenophyllaAnnulariæ, and the Devonian genus ⁠⟨⁠P⁠⟩⁠silophyton— Add this to Saporta’s ⁠⟨⁠Si⁠⟩⁠lurian Fern. Are we going to have ⁠⟨⁠an⁠⟩⁠ unchanged Flora from the ⁠⟨⁠bas⁠⟩⁠e of the silurians to the summit ⁠⟨⁠of⁠⟩⁠ the Carboniferous beds? it ⁠⟨⁠looks⁠⟩⁠ like it!5

Footnotes

In 1877, Williamson had sent CD specimens showing that in its early stages, Drosera spatulata (spoon-leaved sundew; spathulata is a common misspelling) resembled D. rotundifolia (common or round-leaved sundew; Correspondence vol. 25, letters to W. C. Williamson, 22 October [1877] and 24 October [1877], and letter from W. C. Williamson, 23 October 1877).
Francis Darwin’s paper ‘Experiments on the nutrition of Drosera rotundifolia’ (F. Darwin 1878a) had been read at the Linnean Society on 17 January 1878.
John and Ellen Frances Lubbock lived at High Elms, Down. There is no record of Williamson and his wife, Annie Copley Williamson, visiting Down House in 1878, nor is there a record of their visiting the Lubbocks in John Lubbock’s diary (British Library MS ADD 62680).
In Lesquereux 1877, Leo Lesquereux described a number of fossil plants found in Silurian beds in North America, including Psilophytum (a synonym of Psilophyton), which he said was a primitive and diminutive type of Lepidodendron (an extinct tree-like plant from the Carboniferous; Lesquereux 1877, p. 172). Gaston de Saporta described a fern found in Silurian beds in France in Saporta 1877a. Williamson was publishing a series of articles on fossil plants from the Carboniferous in Philosophical Transactions of the Royal Society of London (Williamson 1871–92). Sphenophylla and Annulariae are slips for Sphenophyllum and Annularia; both are in the class Equisetopsida.
