A hypanthium is a flower floral structure consisting of the bases of the sepals, petals, and stamens fused together. Its presence is diagnostic of many families, including the Rosaceae , Grossulariaceae , and Fabaceae . In some cases, it can be so deep, with such a narrow top, that the flower can appear to have an inferior ovary plants ovary . In eucalyptus this structure is commonly known as the gum nut . Geometrics The various shapes of the hypanthium structure are useful in species identification.

Unlike most members of Myrtaceae, the arrangement of leaves are opposite in this species. The leaves are grey green, scented, between 4 and 7 mm long, 1 mm wide, semi cylindrical or triangular in cross section, and terminate in a short and sharp point. Floral leaves differ from these, appearing as small bracts. The small flowers are in a dense and corymbose arrangement at the ends of the branches, these are pink and white and slightly fragrant. The calyx has a cylindrical hypanthium which is divided into three to six hair like forms on each of the upper lobes. The specific epithet commemorates Johann Freiderich Carl Wilhelmi Carl Wilhelmi , a collector of seeds and specimens of the region, who obtained the type collection at Port Lincoln in November of 1854. The first description, published by Ferdinand von Mueller in 1855, was as a species of Verticordia , this gave rise to the common name of Eastern Feather flower . No current species of verticordia occurs in the region. The shrub was later transferred to its current arrangement by the mycologist Edwin Cheel . The species is not well known to horticulture , although trials in its cultivation have been successful in a number of regions of Australia. H. wilhelmii has been propagated, by enthusias ... more details

Because of the special lack of worldwide knowledge about the family lauraceae in general, very little is known about their diversity. Recent monographs of the small and medium genera of lauraceae with up to 100 species per genus have produced a high increase in the number of known species. This high increase is expected for other genera as well, particularly for t ... more details
