| Data on structure and chemistry of oil bodies are being provided for twenty species of leafy Hepaticae, most of them belonging to Lejeuneaceae. Oil bodies are described as new for Symbiezidium, which stands out among Lejeuneaceae by its large, Bazzania-type oil bodies. The observed occurence of segmented as well as homogeneous oil bodies in Archilejeunea and Dicranolejeunea constitutes a further break-down of what was generally considered a stable generic character in Lejeuneaceae. Detected chemical compounds include a large number of unidentified terpenoids. Sesquiterpene lactones, traditionally considered important chemical markers for Frullaniaceae, were newly detected in Lepicolea (Lepicoleaceae), Clasmatocolea (Lophocoleaceae) and Omphalanthus... |
