Eryngium
Eryngium (sea holly; family Umbelliferae) A genus of shrubby, often spiny,
perennial herbs which are unlike the characteristic umbellifers in appearance. The lobed or deeply cut leaves are toothed and without
stipules. The
sessile flowers are held in a dense head surrounded by leafy, spiky, and showy
bracts. The
calyx teeth are often sharp, rigid, and longer than the
petals. The 5 petals are narrow and notched, with free
stamens and an
inferior ovary with 2
unilocular carpels. The fruit is a 2-celled
schizocarp which splits into 2 single-seeded fruits. There are about 230 species, found in temperate and tropical regions, where they are often found in arid conditions.
