[swbiodiversity.org] Description, Etymology: Cryptantha barbigera is distinguished by being a mostly erect, slender, densely bristly annual with linear to spatulate leaves; calyx erect in flower and constricted with recurved tips in fruit; 4 same-size tuburculate nutlets with rounded margins; and the style longer than the nutlets. Strongly resembles C. nevadensis, but that species often has lax, flexulous branches (ascending in C. barbigera) and a mixture of appressed and spreading hairs on the stems and leaves (spreading hairs only in C. barbigera). 2015 Etymology: Cryptantha comes from the Greek krypto, "hidden," and anthos, "flower," a reference to the first described species in the genus which has inconspicuous flowers that self-fertilize without opening; barbigera means bearded.
