Czech botanist
 Ladislav Josef Čelakovský (November 29, 1834 – November 24, 1902) was a Czech botanist born in Prague. He was the son of writer František Ladislav Čelakovský, and father to mycologist Ladislav František Čelakovský (1864-1916). He took an evolutionary approach to the study of plants, alternation of generation, flower structure and other aspects.
Life and work.
Čelakovský studied at Charles University in Prague, and from 1860 gave lectures at the National Museum in Prague. In 1880 he attained the chair of botany at the university. 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. Čelakovský was a supporter of Darwinism and took an evolutionary approach to his studies. 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). He described numerous new plant species, and a handful of plants are named after him including "Stipa celakovskyi", "Lathyrus celakovskyi" and "Orchis celakovskyi".
