Discussion

Plants of subsp. propinqua with obtuse corolla lobes, to which the epithet arctophila has been applied, occur in the same populations throughout much of the range of the species as plants with bristle-tipped corolla lobes and plants intermediate in this respect. Branched and small, unbranched plants likewise occur within the same populations (J. M. Gillett 1957). From specimens now available, the character states alleged by E. Scamman (1940) to divide Gentianella propinqua in mainland Alaska into two groups, most readily distinguished by plant size and anthocyanin concentration in the leaves and stems, appear neither well marked nor consistently associated in syndromes.
