Scandix L.

Linnaeus, Sp. pl.: 256 (1753).

Small annuals with narrow-lobed leaves. Umbels sessile or short-stalked, without bracts and with rather few rays. Bractlets entire or serrate to lobed. Flowers not to distinctly zygomorphic, without sepals; petals white. Fruit elongated, with a laterally slightly flattened seed-bearing part, and a dorsiventrally flattened to ± terete beak (parts equally long or the beak longer); ridges low, straw-coloured to greenish (as the beak); valleculae wide, each with 1 dark brown vitta visible on the surface; stylopodium high-arched to stipitate, discoidal; style thick and short.
Chromosome base-number x=7, 9, 11.

Distribution. An archaeosynanthropic field weed in eastern D and southern S (recent finds only in S Öl and Gtl), elsewhere a casual alien, mainly brought in with ballast (late 19th and early 20th century) or with grain, in F probably also (1940’s) with German straw. – D according to Lange (1886–88) and Jessen & Lind (1922-23) a weed of cereal fields once common in LFM and known as such also from NJy, ØJy, VJy, FyL and Sjæ; latest province records FyL Tranderup 1926, Brn Grisby 1943, ØJy Århus 1945, VJy Troldhede before 1950, LFM Maribo and Møns Klint 1960, NJy Gudumholm 1962, Sjæ Amager 1973.
