AMERICAN FERN VOLUME NUMBER 90 JOURNAL: 9B (2006) 3 qiiorcctin are here reported for Ihe time from [he genus Dryopteris whereas first apigenin has previously been found in a single species of this genus, D. by setigera Voirin (Ph. D. thesis, University of Lyon. 1970). As shown in Markham genin has mb previously been found in a ni Nothokwna, Hyinenophyllum, and Pteris Cheilanthes whereas kaempferol together with quercetin have been found number in a of fern species belonging Mm HymenophvUum, Moh manes whereas quercetin has bc^en identified in the genus Botrychium. It is of interest to note that apigenin, kaempferol and quercetin in Dryopteris are not "external" flavonoids villarii flavonoid aglycones occurring on (i.e. outside of the fronds) because Wollenweber 931- (Phytochemistry et 48: al. 939. 1998) reported the absence of flavonoids among the compounds produced by external glands of leaves of D. and D. arquta Maxon; villarii (Kaulf.) W Wid 120. 1991) identified acylphloroglucinols rhizomes and in of D. villarii D. arguta; the acylphloroglucinol composition of external glands from different is that of rhizomes. Wollenweber suggested et (1998) that acylphloroglucinols al. may have an ecophysiological function and has been reported by and Clarke it Harvey 197-198, 2"'^ Veterinary Toxicology, London. (pp. ed., Ballaire Tindall, rhizome 1981) that acylphloroglucinols of Dryopteris produce filix-mas neurotoxic rhizomes and effects in cattle eating fronds of this fern.
