This series is the same as the Etuberculatae of Schumann and contains but a single species, 

 recorded as a native of Chile. According to Schumann, the stems are cylindric to clavate, not 

 tuberculate, the leaves are small and caducous, and the spines are very small and appressed. The 

 fruit is said to contain one woolly seed.
