Candolle

To the celebrated French botanist Alphonse de Candolle he wrote:

However, while de Candolle’s results showed the importance of environmental conditions on the average population, his data did little to explain individual differences within a population.

Alphonse de Candolle starved plants, with the result of producing better blooms, and found that seedlings from these were also above the average in luxuriance of blossom, but in these experiments the effects of selection during the starvation, and of direct effect on the nutrition of the seeds, were not eliminated.

At Geneva are three large collections—Augustin Pyrame de Candolle’s, containing the typical specimens of the Prodromus, a large series of monographs of the families of flowering plants, Benjamin Delessert’s fine series at the Botanic Garden, and the Boissier Herbarium, which is rich in Mediterranean and Oriental plants.

This floral clock of Linn�us was calculated for Upsala, Sweden; De Candolle gave another for Paris, and one has been arranged for our Eastern states.
