Group of rectangularis . Australian species of medium size with more or less axially compressed petiolar node; in 3 of the species, nodal summit transverse and concave in the middle, the free angles forming teeth in one of these species ( paripungens , rectangularis , armstrongi ). In the fourth species ( turneri ) the node is thick and rounded above (fig. 33), but this species seems otherwise related to rectangularis .
