Discussion
Carex laxiculmis var. copulata has been treated as a variety of C. digitalis or C. laxiculmis, as a distinct species, and as a hybrid between C. digitalis and C. laxiculmis. Regular pairing during metaphase-I indicates that C. laxiculmis var. copulata is not a by-product of hybridization (R. F. C. Naczi 1999). In lateral spikes, a proximal sterile scale or scale subtending a staminate flower clearly places the affinity of this variety with C. laxiculmis rather than C. digitalis (C. T. Bryson 1980).
