In this report a list of all Oenothera species found in Franconia is given and Oenothera stucchii, a particular tall (up to > 2 m) species with extremely long Hypanthia of 50-70 mm and fruit capsules with truncated teeth, is described and depicted in more detail.}, subject = {Nachtkerze }, language = {de} } @article{Meierott2008, author = {Meierott, Lenz}, title = {Cerastium brachypetalum Desp. ex Pers. und Cerastium tenoreanum Ser.

This subspecies is restricted to the slopes of the Main valley between W{\"u}rzburg and Hasloch with a hot spot (>90\% of total population) between the villages Th{\"u}ngersheim and Retzbach. Due to some similarities with H. glaucinum subsp. prasiophaeum (synonym: subsp. gougetianum) the subspecies is named H. maculatum subsp. pseudogougetianum. This subspecies grows preferentially on shell-bearing limestone gravels and begins flowering as early as mid-April. Head involucra are whitish hairy mixed with dark stalked glands. The basal leaf rosette consists of ovate to elliptic, toothed to serrate, dark spotted leaves, glabrous, glaucous above. Stems bear 1-3(4) stalked stem leaves and usually form long lateral flowering branches from the leaf axils. Like some other H. maculatum subspecies, H. maculatum subsp. pseudogougetianum is tetraploid with a mean genome weight (2C value) of 14.5 pg, distinguishing it from the H. glaucinum group, whose studied taxa are invariably triploid (mean 10.1 pg).}, subject = {Korbbl{\"u}tler}, language = {de} } @article{KirchmeierMeierottJung2023, author = {Kirchmeier, Peter and Meierott, Lenz and Jung, Klaus}, title = {Taraxacum sect.
