Lysimachia vulgaris, Euphrasia officinalis, Rhinanthus crista-galli, and Violatricolor come under this head.
2
Nearly the same result followed with some crossed and self-fertilised plants of Violatricolor.
3
Strictly analogous experiments with Violatricolor and Lathyrus odoratus gave a very different result.
4
This was evidently the case with the crossed plants of Violatricolor, which ultimately quite overwhelmed the self-fertilised.
5
In my first experiments on Violatricolor I was unsuccessful in raising seedlings, and obtained only one full-grown crossed and self-fertilised plant.
6
In all three pots of Violatricolor, naturally crossed plants the offspring of crossed plants flowered before naturally crossed plants the offspring of self-fertilised plants.
7
I find from experiments that humble-bees are almost indispensable to the fertilisation of the heartsease ( Violatricolor), for other bees do not visit this flower.

Violatricolor-crossedand self-fertilisedplants, left uncovered and cross-fertilised by bees, produced capsules in number: 10.
9
Violatricolor.-Setsvery few and poor capsules.
10
Violatricolor: seedlings from crossed and self-fertilised plants, the parents of both sets having been left to be naturally fertilised.

Violatricolor-crossedand self-fertilisedflowers on the crossed and self-fertilisedplants of the 1st generation yielded seeds as: 69.
