Biology of Isoëtales, a colloquium in honor of Dr. W. Carl Taylor.

IsoŽtes, commonly known as the quillworts, is a widely distributed lycophyte genus of about 250 species occurring in diverse habitats. Extant IsoŽtes are mostly small aquatic to semi-aquatic with reduced cormose stems. IsoŽtes is the only extant genus of the IsoŽtales. The heterosporous, ligulate lineage that it belongs to has a rich fossil record, and paleobotany studies suggest that related plants dominated the Late Carboniferous coal swamps. This colloquium will be dedicated to Dr. William Carl Taylor (Smithsonian, retired). Its main objective is to highlight recent research relating to Carl's contributions to the study of IsoŽtes, and to survey past and current research on this lineage. When Carl began his studies, it was believed that IsoŽtes did not hybridize and there was no polyploidy in the genus. Carl realized, however, that hybridization and polyploidy were important evolutionary mechanisms in the genus. His studies paved the way for other IsoŽtologists to study these phenomena. When Carl began his career, about 50 species of IsoŽtes were recognized. Today, that number stands at about 250. Much of the reason for this increase is the impetus Carl gave to the field. Carl also promoted systematic botany as a program officer at the US National Science Foundation. He has written a book of the ferns and lycophytes of Arkansas and authored many papers on IsoŽtes.
