Summary:
Disputes Thomas Meehan’s observations on the hardiness of exposed buds, and believes bud-scales are for the protection of the bud-leaves. Reiterates his opinion that the phyllotaxy of a plant is determined by causes acting when the leaves are crowded into close contact. Attempts to explain how a different phyllotaxy on the upper and lower parts of the same shoot could have arisen.
