From John Price   10 September 1874

Watergate St. | Chester

Sept 10. 1874

My daur.1 remembers with me that U. vulgaris did float, at any rate, before the bladders were nudocularly visible. I have seen one, out of dozens, giving out air rapidly, in minute bubbles, for hours2

J. P.

The squashed U. minor was sent to show good will.3

J. P.

The last ought to be good I can not get U. vulgaris now.


Price’s daughter was Mary E. Price.
Price had previously written about bubbles emitted from Utricularia vulgaris (common bladderwort; see letter from John Price, [c. 27 July 1874]). In Insectivorous plants, pp. 397–8 and 404, CD remarked that the plants generally floated near the surface of the water and that the bladders, though often containing air bubbles, did not serve as floats. Nudocularly: with the bare eyes; a coinage of Price’s own.
CD had asked Price to send more specimens of Utricularia minor (lesser bladderwort) in his letter of 28 July [1874].
