CARROT FAMILY 



Roots. — Thick, tap, white, poisonous. 



Stems. — Tough, smooth, grooved, hollow, often stained 

 with brown. 



Leaves. — Basal leaves pinnately compound, often 

 eighteen inches long, with long grooved petioles. Leaf- 

 lets coarsely and sharply toothed, often cut-lobed, irregu- 

 larly serrate-dentate. 



■Flowers. — Greenish yellow, borne in flat -topped com- 

 pound umbels three to four inches across, eight to fifteen- 

 rayed. Petals small, golden-yellow, tips incurved. 



The Wild Parsnip is a tall, widely branching, thick- 

 rooted biennial herb, standing along the roadway and 

 blooming in July. The little yellow flowers are all 

 of the same size, and each tiny petal tip is incurved. 

 This plant is either the Garden Parsnip gone wrong, 

 or else the primitive from which the Garden Parsnip was 

 developed. In either case it is no longer a food but a 

 poison, even after it has been cooked. Moreover, 

 it is reported as the host to a fungus which infects 

 and destroys Celery plants.
