(Q)

Aug 17th/55/ 34 of these sub vars. of 10 week-stocks came into flower producing 140 plants, ie on an average 4 of each Kind; every one of these 140 came true to its tint, except one single one which was slightly wrong. When I say all came true to tint I confess some few of the tints were hardly perceptibly different, but what I think more important, is in each row (with the single exception) there was not a false Kind.

N.B. these were sub-vars of one var of 10-week stock which is according to best Botanical only var. of Mathiola— ?—

It is curious no difference except in colour of seeds & flowers — let no one think any fixed relation in this head. →

[A17v]

In these plants there are about 20 distinct tints, several do not correspond with name, but what makes me call them true, is in each row (& one row had 10 Plants) there was only the one case of difference.
