Eryngium yuccifolium, Var: synchaetum
Apiaceae [=Umbelliferae] (Parsley) Family
Plant is an upright perennial with a taproot. Preferred habitat is prairies, roadsides, woods and pine woods. Distribution is throughout the Escambia region.
Leaves are alternate; linear; leathery texture; and parallel veined; margins toothed to nearly sharp-spined.
Flowers are in a terminal umbel; bisexual; symmetrical; in heads subtended by egg-shaped to lance-like bracts; five petals; white. Flowers occur in the summer.
Fruit is an oval ovary with two or more seed chambers.
The leaves were once thought to be a remedy for snake bite, thus the name. The spiny leaves make walking through clumps of these plants difficult, and also make them unpalatable for grazing livestock.
