Discussion | Erythranthe patula is distinctive with its long-petiolate leaves with ovate blades and its small, weakly bilabiate to nearly radially symmetric corollas. Vestiture may include only minute, stipitate-glandular hairs or it may be an intergrading mix of stipitate-glandular hairs and minute (0.1–0.2 mm), sharp-pointed, eglandular hairs. Plants may have stipitate-glandular pedicels and calyces but hirtellous, eglandular stems, or they may have stipitate-glandular stems and pedicels but hirtellous calyces.

Erythranthe alsinoides is distinct in its short, erect stems with few nodes, small, mostly ovate to elliptic-ovate, petiolate leaves, minutely stipitate-glandular vestiture, small corollas with a prominent maroon splotch on the abaxial limb, small, non-inflated mature calyces and, most especially, by its nearly truncate calyx margin. Erythranthe pulsiferae is superficially similar to E. alsinoides but has larger calyces borne on divergent-arcuate pedicels, smaller leaf blades with attenuate to cuneate bases, and the corolla limbs are smaller and lack a prominent maroon splotch.
