Note 70 — Chapter XI · ON BUD-VARIATION, AND ON CERTAIN ANOMALOUS MODES OF REPRODUCTION AND VARIATION.
Reading edition
M. Lemoine (quoted in ‘Gardener’s Chronicle,’ 1867, p. 74) has lately observed that the Symphytum with variegated leaves cannot be propagated by division of the roots. He also found that out of 500 plants of a Phlox with striped flowers, which had been propagated by root-division, only seven or eight produced striped flowers. See also on striped Pelargoniums, ‘Gardener’s Chronicle,’ 1867, p. 1000.
