Leaves of 97 taxa representing all the genera at present recognized in the famil! Oleaceae were surveyed for flavonoids. Four flavonol glycosides were found to be common, the 3-glucmide~ and 3rutinosides of quercetin and kaempferol, as were four flavone glycosides, namel! thr 7-glurosides arid 7-rutinosides of luteolin and apigenin. Among rarer constituents detected were luteolin 4'glucoside, eriodictyol 7 -glucoside, chrysoeriol 7 -glucoside, an apigenin-di-C-glycoside and several higher glycosides of quercetin. The species and genera surveyed fell into two groups: thosc with flavonol glycosides alone; and those with both flavonol and flavone glycosides. The most wiking correlation was with chromosome number (and subfamily division) since almost all taxa with a basic number of 1 1, 13 and 14 had only flavonol glycosides, whereas most taxa with x = 23 had both types of flavonoid. Evolutionary advancement in the family ippears to involve the gradual replac.ement o f flavonol by flavone glycosides. Indeed, a few tam, notably Nestegis apelala, Picconia I X ( P /~ arid Tesserandra fluminense, lacked flavonol glycosides in the leaves complet+. At the lowri-Ievrlr of classification, the distribution of Ravonoids is of less interest. However, the patterns i n Linorz~rn and Chionanthuj, two taxa recently made congeneric, are sufficiently different to suggest that this dc-cision might have to be reconsidered when more is known of their chemistr). Othenviw. Iraf patterns generally fit in with the existing generic classification in the family. KEY WORDS :-cheinotaxonomyflavonesflavonolsleaves -Oleo -Oleac rac.

A new combination, Phymatosorus pustulatum, is made for Polypodium pustulatum Forster f., replacing Microsorum pustulatum (Forster f.) Copel. and other synonyms.

It is asserted that, after all, the correct name for the widespread Indo‐Pacific species of Scaevola is Scaevola taccada (Gaertner) Roxb.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
