Four to five spikes per culm; spikes gynecandrous, sessile; spikes well spaced with lowest spikes separated by more than 20 mm; 12-13 visible perigynia per spike in these photos. Perigynia appear to me to be glabrous, without wings, broadest near the middle of the body. Measured one inflorescence at ~5.5 cm long. Bracts sheathless. Leaves ~3 - 3.5 mm wide. Based on the spacing of the spikes, I'm inclined to call this C. canescens ssp. disjuncta, but I'm not sure that the documentation supports subspecific identification.

First state record discovered in May and collected July 30. Duplicates to be sent to University of Wisconsin, University of Michigan, and Michigan State University. Present on high hummocks throughout this peatland, but this collection from underneath spruces along a minerotrophic channel draining a large spring. Habitat shot & comparisons with C. trisperma in last 6 photos.

Found deep in the swamp. Small and hard to spot, this variety is very rare in Massachusetts, though all varieties are state-listed as endangered. This one has a lovely sweet scent, like a fine and delicate perfume.

M.J. Oldham, A.A. Reznicek, and Eagle Hill sedge class 44379; specimen record, replicates at NHIC# 02842 (home), +2; identification by A.A. Reznicek; moist open field, with Carex scoparia, Danthonia spicata, Spiraea alba; locally common; photos; Lat Long accuracy 10m

Esse registro tem uma história curiosa. Postado no site Wikiaves (https://www.wikiaves.com.br/4442204), foi inicialmente confundido com a vocalização de uma coruja, até que um colega sugeriu que poderia pertencer a um anfíbio do gênero Phyllodytes. Encaminhei o áudio para uma amiga, cuja sobrinha, herpetóloga, identificou como Phyllodytes kautskyi.
O artigo abaixo representa o sonograma da vocalização dessa espécie, bastante semelhante ao do meu registro.

Several thousand stems in 8 inches of water in a pristine pond in the Berkshires. Apparently my three iNat observations are the only three in all of New England. I does occur in all six states, though.

On wooded hummock near pond. Culms 25-40cm, filiform. Leaves to 40 cm, 2mm wide. Plant bases wine-red bladeless sheaths. Perigynia fuzzy, 2.2mm x 1.3mm, short beak. Achene trigonous, brown, 2mm long.

State endangered, globally rare. This is the fourth observation in all of iNat. Leaves are like Carex vestita but glabrous perigynia puts it into section Paniceae. Plants are widely spaced on long rhizomes. This is a known population, not my find, but still awesome to see. Protected by our state endangered species act which turned 30 years old last year.
