Résumé :	In a leaf flavonoid aglycone survey of 19 Tricyrtis species, the flavone lulcolin was detected in 16% of the taxa and the flavonols myricetin, qucrcetin, kaempfcrol and isorhamnetin in 32%, 63% and 68% and 58% of the sample, respectively. Kaempfcrol occurred more frequently than qucrcetin in sections Hirtae and Tricyrtis. Section Brachycyrtis was characterized by the presence of lulcolin, while flavoncs were absent from sections Flavae, Hirtae and Tricyrtis. Myricetin was found only in T J'ormosana and T. hirta (section Hirtae) and in T affirm and T. macropoda (section Tricyrtis). This is the first report of myricetin in Tricyrtis and in the Liliales. Also the co-occurrence of flavones and flavonols within the same plant, as in 7. ishiiana var. surugensis and T macrantha, is a rare event in this order. The flavonoid data are congruent with data from morphology, anatomy and molecular analysis in indicating the separation of section Brachycyrtis from the other three sections and in supporting a close relationship between sections Hirtae and Tricyrtis.
