ID notes: Among section Ozophyllum, J. trigonocarpus has large heads and a smooth green stems. The capsules and seeds are large but noticeably smaller than J. caesariensis and larger than J. canadensis. Young J. trigonocarpus and J. canadensis are often confused; once mature, however, the two can usually be separated by capsule color alone. Although J. canadensis capsules redden, they never approach the dark reddish-purple tone of J. trigonocarpus. Seed and capsule size are also distinct for the two taxa.
