Bunched Arrowhead (Sagittaria fasciculata)

Family: Water plantain (Alismataceae)

Federal Status: Endangered, July 25, 1979

Best Search Time: Mid-May through July

Description: Bunched arrowhead is a small herbaceous plant growing 15 - 16 inches (in) (38 – 41 centimeters; cm) tall in saturated soils. It’s the only Sagittaria species in the Southern Appalachians that does not have arrowhead-shaped leaves. Emergent leaves are broad and tapered at the tip and up to 12 inches (in) (30 centimeters; cm) long and 1 – 2 in (2.5 - 5.1 cm) wide. The white flowers begin blooming in mid-May and continue through July. The fruits mature a few weeks after flowering.

Habitat: Bunched arrowhead occurs in undisturbed sites that are typically located just below the origin of slow, clean, continuous seeps on gently sloping terrain in deciduous woodlands.

Distribution: Bunched arrowhead is known from the upstate of South Carolina and southwestern North Carolina.

Threats: The primary factor determining the rarity of Bunched arrowhead is the current rarity of its required habitat. The seepage habitat in which Bunched arrowhead occurs is extremely threatened, and remaining Bunched arrowhead populations are threatened by residential and industrial development, conversion to pasture, and invasive exotic species.
