Longevity & Vitality of Seeds

July 2 74

Late last winter a portion of sandwalk wood where the thicket was extremely thick was grubbed up, so that the earth was turned up from a considerable depth. The space is 14 ft x 7 giving 98 sq feet. Now as Charlock plant came up I marked it, & the plants being now in flower I find the number to be 46, so that there are almost one plant to each 2 sq feet. See Gard: Chron 1855 p 758 for history of this wood. The plant is ~~Sinapis~~

[pencil insertion by Darwin:] Brassica sinopistrum (I think came from seeds are said not to keep well)
