Discussion

Except by geography, subsp. occidentalis is very difficult to distinguish from subsp. decumbens. In plants of subsp. occidentalis the sepals tend to be more orbiculate and the capsules, prior to dehiscence, tend to be more globose. Extremely variable, subsp. decumbens generally can be recognized on the basis of presence of tuberculate seeds (60% frequency) and 80% have a combination of tuberculate seeds and glandular-pubescent pedicels and calyx bases. But when seeds are smooth, seeing the reticulate ridge pattern requires high magnification, and while SEM readily clarifies the differences, its use is hardly practical. Subspecies decumbens has a greater tendency to possess purple sepal tips or sepal margins, and purplish coloration frequently at the nodes.
