Speeies enumerat Steudel 196, verisimiliter ad dimidium reducendas, per orbem terrarum latissime 
dispersas; in uliginosis locisque humidis regionum temperatarum frigidarumque neenon in arenosis 
maritimis copiose crescunt, sed etiam inter tropicos inveniuntur. Kwunth, Enum. PI.ii. 315. Steud.

Species plures fere cosmopolitane quam maxime variabiles sunt, et difficillime characteribus certis 
distinguendz v. ordinande. Seminum variationes, ab Engelmannio 1. c. optime illustratz; cum aliis 
h ibus minime iunt, et sectiones nullz definite adhue proposite sunt. Engelmann 
tamen series 3 imprimis ad habitum bene distinguit :— * 
1. Junci genuini, caule aphyllo basi vaginis aphyllis v. rarius folium ipso cauli simile gerentibus. 
2. Junci graminifolii, caule nudo v. foliato, foliis planis v. semiteretil lieulatisque v. rarius 
subteretibus. : 
3. Junci articulati, caule foliato, foliis teretibus v. compressiuseulis, intus septis transversis 
instruetis specie artieulatis, ; : 
Buchenau divisionem primariam petit a presentia v. absentia prophyllarum, i.e. b sub 
floribus hyalino-seariosarum, character tamen nobis valde incertus videtur. Bracteas in perplurimis 
speciebus 2 vidimus sub quoque flore, nune immediate sub flore, nune in medio pedieello quarum 
infera vaeua, superior sepe rudimentum floris fovet et; haud raro adest tertia, uti bene observavit
