Observations by Gary Fewless for Green Bay WI (Lat.N 44.51° Long. W 88.02° ), except as noted. For flowers lacking conspicuous petals or sepals I define "anthesis" as release of pollen by mature anthers.
Mystery Photo October 26 2001: Hazelnuts
The photos below illustrate the difference between the two species of Hazelnut in Wisconsin. American Hazelnut is found nearly throughout the state, but Beaked Hazelnut is mostly found in the northern half. Both species grow in a variety of habitats, but do best on dry sites in full sun and may be very conspicuous after forest fires in the north. The nuts are edible, but smaller than their close relative the "filbert", and they require a fair amount of work to remove the outer husks and then crack the nutshell within, as shown below right.
