Ladislav Josef Čelakovský

He took an evolutionary approach to the study of plants, alternation of generation, flower structure and other aspects.

In 1877 he became a member of the Königliche Böhmische Gesellschaft der Wissenschaften (Czech Royal Society of Sciences).

Čelakovský conducted extensive research involving classification of plants, particularly studies of regional flora from what is now the Czech Republic.

[1] He made important contributions on the morphology and physiology of the reproductive organs of Gymnospermae.

Other major works included “On the General Evolution of the Vegetable Kingdom” (1868), “On the Different Forms and the Meaning of the Alternation of Generations in Plants” (1874), “The Law of Reduction in Flowers” (1894), “The Evolution of the Flower” (1896 and 1900) and “On the Relationship between the Different Methods of Morphological Research” (1874).
