May 26 — 1862— a few Pods — Chinese Primroses; brought me by Mr Horwood

(N. B. I have counted all the seeds, except the very small & manifestly bad.) The empty pods not brought & there were many

Horwoods seedlings: thumb-eyed or mid-styled (picked pods by Mr Horwood)

These no doubt were so far picked as the upper Ducks were, so that none with no seed were brought

[Data and calculations not transcribed]

Horwoods seedlings 4 plants kept in my greenhouse

N. B. These plants not covered, but then there were very few others. Ducks the same— The other were plants which had flowered & were picked

Horwood seedling

Black worsted. 30 22 45 31

White worsted 29

(This tells nothing)

If anything [illeg]

The far greater number of pods of Horwoods were then set where all the plants were long-styled & mid-styled ie all short stamens & therefore could not have been crossed. The vast number of pods may be accounted for by young flowers getting their own pollen. These pods of same kind, some few empty all 180 in number borne by only 4 plants!!!
