167. C. echinata Murr. ; C. stelliilata Good. 



Very common in pools and on peat}^ ground in low-lying regions, 

 also found some distance up the hills e. g. Str : Nigvan, 320 m. (C.J.); 

 Syd.: between Famien and Vaag, at some 350 m (!). 

 Fl. June— July. Fr. August — September. 



168. C. flacca Schreb.; C. glaiica Scop. 



Found here and tbere on ledges and dry piaces beyond enclosed 

 fields, only in low districts. 



Fl. June— Jul3^ Fr. August — September. 



169. C. flacca Schreb. X Goodenoughii Gay, nov. hybr. 

 Bordo: a rock-ledge near Bordovig (!). 



We gathered a curious species of Carcx on Bordo , which , ac- 

 cording to Mr. Raunkiær's anatomicai examination, turns out to 

 be the above-mentioned hybrid not hitlierto known; its external 

 characteristics also prove this: the leaves glaucous on the under- 

 side from a waxy covering: rnnners short and vigorous with shin- 

 ing-brownish sheaths like those of C. flacca; with regard to its 

 inflorescence and other characteristics it resembles C. Goodenoughii ; 

 but it is sterile. 



We only saw a single luft in the locality in question. 



170. C. flava L.; C. Oederi, Ostenf. II p. 16. 



Common in bogs and pools in the lowlands and up to 2 — 300 m. 

 (on Syd., between Famien and Vaag, at about 350 m.). 



I was formerly of opinion that the form of the group Flava which 

 occurs on the Færoes ought properly to be cailed C. Oederi, as the spe- 

 cimens are mostly small, with the lowest fertile spike separated from the 

 otliers, all the spikes rather small and the beak of the fruit slightly 

 curved downwards; but on furthcr investigation I arrived at the con- 

 clusion that Rostrup was right in naming them C. fUwa. Strangely enough 

 C. flava is both in Iceland and Greenland replaced by C. Oederi, while 

 in the Færoes the reverse is the case. 

 F'l. July. Fr. September. 



171. C. flava L. X fulva Good; C. fniua Rost. 1. c. p. 65, et Auctt. 



Grows together with the two primitive species at a few stations; 

 Kuno: at the southern end of the island, at some 100 m. (!); Syd.: 

 near Tværaa i!) and Hove (R.). 



172. C. fulva Good.; C. Hornschuchiana Hoppe. 



Rather rare in bogs. Kuno: at the southern end of the island, 

 at some 100 m. (!); Str.: at the ravine at Vestmanhavn (!); Syd.: at 

 several stations, e. g. Kvalvig (!), Trangisvaag (!), Tværaa (R., !), Frodebo 



(R.) and Hove (R.).
