Nemacladus glanduliferus is a species of flowering plant in the bellflower family known by the common name glandular threadplant. It is native to the southwestern United States and Baja California, where it grows in desert and plateau habitat. It is an annual herb producing a purplish or brownish green, branching stem up to about 25 centimeters tall. Small oval leaves occur at the base of the plant. The inflorescence is a series of zigzagging branches bearing occasional flowers on thin, erect pedicels. There is a single small bract at the base of each pedicel. The flower at the curved tip of the pedicel is just a few millimeters wide. There are five pointed sepals and five white corolla lobes, generally three in the upper lip and two in the lower.

09Environmental DNA1 detections
Where the DNA of Nemacladus glanduliferus was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
