Agalinis obtusifolia is usually found in dry habitats and less frequently in more hydric conditions. The following suite of characters is useful for differentiating A. obtusifolia from A. decemloba, A. flexicaulis, and A. skinneriana: stems and branches stiffly erect, brittle, prominently siliceous-ridged, stramineous when dried; leaves obtusely and narrowly elliptic-spatulate, margins scabrous and revolute, stramineous when dried; calyx lobes minute and deltoid; corolla lacking internal markings or markings faint; and inflorescences of interrupted racemes with secondary and tertiary branches bearing pseudoterminal flowers. Characters useful for differentiating A. obtusifolia and A. tenella are discussed under 32. A. tenella.
F. W. Pennell (1929) used the name Agalinis erecta (J. F. Gmelin) Pennell for A. obtusifolia. Pennell based his combination on Anonymos erecta Walter, an invalid name.
