| Abstract: | Evidence based on flavonoid constituents is cited in support of the existence of two species in the genus Hymenophyton, H. flabellatum and H. leptopodum. A number of apigenin 6,8-di-C-pentosides and pentoside-hexosides are common to both species but the proposed additional species, H. leptopodum, is distinguished from H. flabellatum by the presence of kaempferol di- and triglycosides. This is the first detailed study of the flavonoid chemistry of any member of the order Metzgeriales and the significance of the findings is discussed. |
