Habitat and distribution.
Tanaecium tetramerum is known from Central South America, where it occurs in Bolivia (Cochabamba, Santa Cruz), and Paraguay (Alto Paraguay, Chaco). This species occurs in xerophytic vegetation along the Chaco, in transition areas between the Chaco and Bolivian Chiquitano, Interandian, and Andean valleys. Tanaecium tetramerum generally grows on sandy soils or rocky outcrops.
Phenology.
Flowering: January to February, August and November; fruiting: January to February, April, and July.
Notes.
Tanaecium tetramerum is characterized by a series of unique morphological features that allow this species to be easily separated from other species of Tanaecium such as the thorn-tipped branchlets, terminal leaflets never replaced by tendrils, corollas actinomorphic, hypocrateriform, and 4-lobed ( Gentry 1990; Pace et al. 2016) (Tab. 1 View Table 1 ).
