Taxonomic remark The [var. altior] is possibly a hybrid between C. tentaculata and C. lupulina, for the achenia are abortive. It may be Schkuhr's G. G. G., judging from the number of the nerves on the perigynium, and the absence of the achenium in the figure. It differs from C. halei and from C. lupulina in the squamae; from the last also in the more divergent spikes and perigynia, narrower and shorter bracts, and narrower leaves. The absence of achenium deprives us of the clear evidence it would afford as to the affinity. As the existence of hybrids in Carex is doubtless, this plant, as well as C. sullivantii, is deserving of attention. [details]
