Taxonomy: |
| Distinguished from the other three subspecies of G. leptantha by having a corolla tube that is 1–1.5 times the length of the calyx, a cup-shaped corolla throat, and the longest stamen exserted from the throat but having the exserted portion exceeded in length by both the style and the corolla lobes. Sometimes confused with G. ochroleuca, which has a short corolla tube and a throat that is yellow proximally and purple distally. |
