Taxonomy: |
| Included in Erythranthe section Simiola, a taxonomically complex section with poorly understood species boundaries. Herbarium records have not been examined for this species. More data, including molecular studies, research of herbarium records, and additional fieldwork are needed. Similar to E. nasuta; differs in having smaller flowers, having swollen, nectar producing axillary organs at the bases of stems and peduncles, and growing appressed to granitic cliff faces. |
