Du: forms, inter se diverse, exstant: 
1) Magis australis (Upsaliensis ct typus descriptionis Friesianz): culmo 
superne scabriusculo, bracteis angustioribus spicam masc, non superantibus, spi- 
cis angustioribus, glumis semper muticis aterrimis, C. vulgari ct rigide alh- 
nis, À priori distinguitur: culmo firmiori, levi, primo curvulo; folis excur- 
vatis (ut in C. rigida), planis (non canaliculatis), siccitate marg. reflexis, brac- 
tea ima auriculis connatis, lata, culmum superante, spicis magis clavceformibus, 
squamis latis fructus involventibus, fructibus denique punctis profundis v. setu- 
lis minimis (ut elytra insect.) scabris. A C. rzgida statione, culmo, foliis, 
fructibus &c. 
2) borealis (e Lapp. Tornensi, typus determinationis Hartmanni): bracteis 
latis, auriculis discretis, spicam masc. subsuperantibus, culmo robustiori, levi, 
spicis turgidis, glumis acutatis; hzc, inter C. salinam et C. glaucam quasi me- 
dia, propria species optime videtur. A C. salina, quam form: pusillie zemu- 
lant ["buc C. reducta forsan referenda" Fr.), culmo, foliis, fructibus glumisque 
diversa, ct a C. glauca, cujus forma a Laestadio habita, colore viridi, stigma- 
tibus binis, spica masc. solitaria, fem. erectis pallidis differt, — Duo tantum 
specimina vidi exsiccata, quare de hac forma, utrum species a priori removenda 
sit, necne, nil certi proferre audeam. 
63. C. hyperborea (Dreyer Rev. Car. bor. p. 43): spicis fem. 3—4, 
sessilibus, imis brevi-pedunculatis, erectis, oblongo-cylindricis, rarifforis, ad ma- 
sculam approximatis; bracteis planis, foliaceis; fructibus ovato-ellipticis, ore pro- 
minulo, compressis, subenervibus, glumas ovatas, obiusiusculas, fusco-airas exce-

mum revolutis. -
