Escholtzia. 1871.

The From the plants on pots in Greenhouse (on last page) 12 pods were gathered from each lot; but from the self-fert. lot 7 out of the 12 pods contained all or almost all bad seeds. In the other 2 lots several of the pods were bad. So that there were not enough pods to give fair average of seed. The averages, such as they were, were very low; being for the self-fert. plants only 28.8 seeds. It is clear that greenhouse is very unfavourable to their fertility.

Hence I gathered (at 3 successive periods) — an equal number gathered at each period from each row 45 pods from each of the 3 rows growing close to path in garden & described at back of p. 50 G. Of the 45 pods

from the crossed-garden-plants, 4 were bad. Of the 35 from the intercrossed, 5 were bad. From the self plants 9 were bad. I carefully counted the seeds in 21 pods taken by chance from each of the 3 lots of 45 each.

Of the crossed-garden-plants the average was — 67.00

Of the intercrossed average — 56.00

O Do Self-fert — 48.52

Hence we clearly see that the cross from new pollen in comparison with the intercrossed has increased, (not only the number of pods, judging from the greenhouse plants), but the average of seed. Self-fertilisation has made more pods bad & has greatly decreased average of seed, though strangely in this one case plants taller & heavier.

(Tallness perhaps consequence of sterility)
