Description

Little Aguja pondweed is a submersed aquatic perennial herb with branched stems varying in length according to water depth.

Life History

For an aquatic plant, Little Aguja Pondweed has picked a difficult place to live. Little Aguja Creek where the species occurs is prone to both drought and scouring floods. It flowers and bears fruit from May-October. How the plant manages to survive such extremes is not known, but the species has a history of persisting at the site. Only one population is known, and the plant has not been seen recently.

Habitat

It lives in atill, shallow pools in intermittent, spring- fed streams flowing over igneous-derived, rocky substrates in mountain canyons.

Distribution

This plant is known from only one site located on private property, in Jeff Davis County.
