Discussion

Erythronium quinaultense is a tetraploid species apparently derived from hybridization between E. montanum and E. revolutum. It is known only from the southwestern Olympic Peninsula.

Because stolons are absent in Erythronium mesochoreum, most plants in a population produce flowers; nonflowering plants may sometimes appear after flowering plants have flowered. This species is well adapted to prairie fires. The seeds have elaiosomes, and ants may act as dispersal agents (Great Plains Flora Association 1986). C. C. Deam et al. (1941) reported E. mesochoreum from Indiana, but an examination of the specimens cited, now at IND, showed that these are E. albidum. E. L. Braun (1967) reported that many populations of E. albidum in southwestern Ohio indicate introgression with “the Ozarkean var. mesochoreum.” However, personal observation by K. R. Robertson of several Ohio populations in flower confirmed that these plants are true E. albidum, although they occur in prairies and have more or less conduplicate leaves.
