Daucus pusillus, commonly known as American wild carrot or rattle-snake weed, is a species of flowering plant in the family Apiaceae. It is native to North America, where it is found in a variety of habitats, including grasslands, open woodlands, and disturbed areas.

Description

Daucus pusillus is an annual herb that typically grows to a height of 10 to 50 centimeters. The plant has a slender, erect stem that is often branched. The leaves are finely divided and fern-like, similar to those of the cultivated carrot, Daucus carota. The leaves are arranged alternately along the stem.

The inflorescence is a compound umbel, characteristic of the Apiaceae family. Each umbel is composed of numerous small, white flowers. The flowers are hermaphroditic, containing both male and female reproductive organs. The central flower of the umbel is often sterile and may be colored pink or purple, a feature that is thought to attract pollinators.

The fruit of Daucus pusillus is a schizocarp, which splits into two mericarps at maturity. The mericarps are covered with bristles, which aid in dispersal by attaching to the fur of animals.

Distribution and Habitat

Daucus pusillus is widely distributed across North America, from southern Canada to Mexico. It is commonly found in open, sunny locations with well-drained soils. The plant is tolerant of a range of soil types, including sandy and rocky soils.

Ecology

Daucus pusillus plays a role in its ecosystem as a source of nectar and pollen for various insects, including bees and butterflies. The plant is also a host for the larvae of certain butterfly species.

Uses

While Daucus pusillus is not widely used in traditional medicine or as a food source, it is sometimes foraged for its edible roots, which are similar in taste to cultivated carrots. However, caution is advised as it can be easily confused with toxic species such as Conium maculatum (poison hemlock).

Conservation

Daucus pusillus is not currently considered to be at risk, and it is not listed as a threatened or endangered species. However, like many wild plants, it can be affected by habitat loss and changes in land use.
