Note * — Chapter III · AGGREGATION OF THE PROTOPLASM WITHIN THE CELLS OF THE TENTACLES.
Reading edition
Judging from an account of M. Heckel’s observations, which I have only just seen quoted in the ‘Gardeners’ Chronicle’ (Oct. 10, 1874), he appears to have observed a similar phenomenon in the stamens of Berberis, after they have been excited by a touch and have moved; for he says, “the contents of each individual cell are collected together in the centre of the cavity.” [page 44]
