BORN at Conway in 1870, Otto Vernon Darbishire had the advantage of a varied education, passing his school years in Dresden and Florence and pursuing his university studies at Bangor, Oxford and Kiel. Thus he gained not only a wide outlook on life, but became also a good linguist—an inestimable advantage for a scientific worker. After graduating with honours in botany at Oxford, where he studied under Prof. Vines, he went to Kiel, and there took up first the study of Algæ, obtaining the Ph.D. degree. He then became assistant to Prof. Reinke and commenced his investigations into the structure and development of lichens, a study which he pursued throughout his life. He also turned his attention to the taxonomy of this group of plants, publishing an important monograph of the genus Roccella in the “Bibliotheca botanica” in 1899. By his researches and publications on lichens he became one of the leading authorities on this group of plants, and was entrusted with the determination of the lichens collected by the second Norwegian expedition of the Fram and also of those collected by the Swedish Antarctic expedition.
