From John Scott   24 February 1877

Summary

Thanks for Cross and self-fertilisation.

His work on poppy varieties confirms increased vigour with crossing.

JS is carrying out opium poppy experiments CD suggested. He is busy with opium duties. Observing many fields of poppies, day and night, JS finds them remarkably free of insects. Believes they are wind-pollinated and that varieties have prepotent pollen since he has shown they do not cross naturally.

Plans to send a paper on Cyclosis to Linnean Society.

Summary

Comments on various species of Lagerstroemia.

In the series of opium poppy intercrosses made at CD’s suggestion, JS has learned that the reason they failed to intercross was the absence of insects at the period of their flowering.
