The key characteristic of this family is the inflorescence in which the flowers are aggregated in terminal umbels (a flat-topped or convex inflorescence with the pedicels arising more or less from a common point, like the struts of an umbrella). Hence to recognize family members is usually simple (although other families exist, which also flower in umbels). Not so with determinations on species and genus level. Historically, the taxonomy was defined according to fruit morphology, however modern DNA analyses have overturned much of this order. The process of redefinition of the family is not yet finished. There exist many similar taxa and they are often variable. Hence a careful observation of several traits is required to come up with a reliable determination (except with the most common and well known taxa). Fruit shape is still the most helpful for species determination. But, if one finds Anthriscus sylvestris in full bloom, still without fruits, it can be recognized by the following traits:- tall plant up to 1 m in height or more (Fig 10),- white petals with entire margin (Fig.12),- ground and lower stem leaves two to four times pinnate (Fig. 2, 15),- the lower segment of the first order of the leaf is much smaller than the rest of the leaf (Fig.15),- bracts (leaf like structure at the base of the umbel) missing (Fig.11),- but secondary bracts present; they are uniformly radially arranged, about 3 times longer than wide; acuminate (gradually tapering to a sharp point, sides along the tip are concave) and ciliate (with marginal fringes or hairs) (Fig. 3, 17),- sepals missing,- at the base of the plant there is no abundant remnants of old leaves and stems.Not strong, but distinct and pleasant smell of the plant on somewhere in between celery and anise may also help in determination.Anthriscus sylvestris is native to Europe, western Asia and northwestern Africa. It is a common plant in Slovenia and grows everywhere in the Alps up to alpine elevations. As a fast growing plant it is an invasive species in several other areas of the world, as in the United States for example. Ref.:(1) M.A. Fischer, W. Adler, K.
