About Nemacladus sigmoideus G.T.Robbins
Nemacladus sigmoideus is a species of flowering plant in the bellflower family, commonly known as the sigmoid threadplant. It is native to the mountains and deserts around the intersection of California, Nevada, Arizona, and Baja California. This plant is a small annual herb, producing a thin, spreading purplish or brown stem that grows no longer than 12 centimeters. Hairy, sometimes toothed oval leaves, up to one centimeter long, grow at the base of the plant. Its inflorescence is made up of a series of zigzagging branches that bear flowers on thin, S-shaped sigmoid pedicels. A single tiny bract sits at the base of each pedicel. The hairy flower measures under 4 millimeters long, and has five white lobes with yellow tips.
