M.J. Oldham & S. Managhan # 1504, specimen record, replicates at MICH 1388811, TRTE0011569, NHIC# 05949 (home); identified as Carex x sullivantii by A.A. Reznicek 1983; ; first collection for Canada; cited in Oldham & Crins (1988. Can Field-Nat 102(3): 500-507)

In an interdunal swale. All inflorescences still enclosed in the sheathes, but shedding matured spikelets when exposed. Lower branches of the inflorescence about 4 cm long, with spikelets nearly to the base, but not densely crowded like in posted iNat observations from the desert Southwest [for S. compactus].

On xeric mixed sand and fine gravel, mapped by USGS as Palmyra gravelly sandy loam, receiving some salt spray from the highway in winter.

Culms to 55 cm, larger with multiple inflorescences, spikelets about 2.4 mm, achenes flattened. Well past flowering, very weathered, stunted by this year’s drought.
