Distribution
Distichlis bajaensis is endemic to Baja California, Mexico, where it is known from only one location in a salt marsh just outside Rosarito.[1] The habitat is an arroyo with saline and alkaline soils which is grazed by goats and burros.[1]
The grass grows alongside other halophytes including spiny rush (Juncus acutus), iodinebush (Allenrolfea occidentalis), and pickleweed (Salicornia sp.).[1] Genetic and morphological analyses show that the plant is not any other Distichlis, nor a hybrid of the two most closely related Distichlis, and it was described to science as a new species in 2010.[1]
Description
Distichlis bajaensis is a rhizomatous perennial grass growing in short clumps and spreading via stolons. The leaf blades are no more than 1.5 centimeters long and are slightly bent; this bend is a good characteristic for identifying this grass in the field.[1] Like other Distichlis, Baja grass is dioecious, with male and female inflorescences; only the male inflorescence has been included in the official description because no good female specimens have been collected.[1]
