Gilmour, C.N., Starr, J.R. and R.F.C. Naczi. 2013. Calliscirpus, a new genus for two narrow endemics of the California Floristic Province, C. criniger and C. brachythrix sp. nov.(Cyperaceae). Kew Bulletin 68: 85-105.
Taxonomic Comments
This record represents the narrow concept of Calliscirpus brachythrix. Gilmour et al. (2013) newly combine Eriophorum crinigerum (= Scirpus criniger), which is neither an Eriophorum nor a Scirpus, in a new genus, Calliscirpus. Further, this taxon is now split into two allopatric species, C. criniger comb. nov. and C. brachythrix sp. nov.
Ecology & Habitat

Habitat

Calliscirpus brachythrix grows in "alpine and montane meadows and seepage slopes surrounded by conifers. Often near streams, creeks or with underground seeps; alt. 1250 to 3600 m.," often on acidic substrates (Gilmour et al. 2013, Jepson 2025).
