Question
Good evening Arthur Again thank you for you assessment regarding C. lupulinus/grayi. The attached photo is of a bract subtending the inflorescence. I examined blades and they appeared smooth. The bract by contrast had "hook-like" cells along the lateral edges of the bract and also on the midrib. I could not find any scabrous images for comparison. The second image shows a primary and secondary inflorescence. Thank you for your expertise. I have your book, "Sedges of Maine."
Answer
Dear califyank, good morning. The scabrules on the margins of the involucral bract blade provide additional evidence this plant is Cyperus lupulinus, which corroborates the single, sessile spike at the summit of the stem.
