From Bryum capillare Hedw. a variety of flavone glucosides and their 6″ malonyl esters were isolated. Diosmetin 7-O-β-D-glucoside-6″-malonylester, luteolin 7-O-β-D-glucoside-6″-malonyl-ester and 6-OH-luteolin 7-O-β-D-glucoside-6″-malonylester are new flavone malonyl esters. This is the first report of flavone glucoside malonylesters in a non vascular plant. The flavonoid pattern of the gametophyte is different from that of the sporophyte. The chemotaxonomic relevance of these results is discussed.

Fifteen flavonoids have been isolated from the moss Bryum pseudotriquetrum . The new natural products kaempferol 3-O-galactoside-4 ′-O-glucoside, scutellarein 7-O-glucoside-6′′-malonyl ester, pigenin 7-O-neohesperidoside-6′′-malonyl ester and luteolin 7-O -neohesperi-doside-6″-malonyl ester were amongst them . Flavonols were found for the first time in mosses.

The inheritance of wing dimorphism in Apion virenr (Col., Curculionidae). Cross breedings of long and short winged A. virens showed that the wingformation is inheritable and that the brachypterous type is dominant. The inheritance of the flight behaviour is independant from the wing type as flight attempts of short winged weevils were noticed. LiteraturJACKSON, D.
