| Remarks | [“July 10. . . I find (July 14th) (and it has been out some days), at Muhlenbergii Brook, circaeas which are distinctly branched and with large leaf-like bracts, some nearly two feet high. Yet they are evidently the same species that I have found before, and I think that there is but one hereabouts, say C. alpina, which, however, is poorly described by Gray and inadequately by Bigelow. It is from four of five (in shade) to, as here, about two feet high (in sun); is never pubescent, but quite smooth, round-stemmed, swelling at the joints, more or less branched, in large specimens sometimes very much so (vide pressed one), with bracts quite small and slender in small ones, and very large and leaf-like (two on a common axillary branch) in large plants; leaves opaque in open places, heart-shaped, rather slightly and distantly toothed, of the large specimens, at least, not shining.”Journal 8: 406. 1856]
