byei Hornem., known only from the Faroe Islands. By 

 Drejer (1. c. p. 49) a diagnosis in Latin has been pre- 

 sented, which may be inserted here, together with some 

 remarks by Drejer showing the principal characters by 

 which it may be readily distinguished from C. filipendula, 

 maritima, salina, crinita and macrochceta. The diagnosis 

 reads as follows : 



Car ex Lyngbyei Hornem. 



"Spicis masculis sub 2, femineis 3 in pedunculo longissimo 

 gracili pendulis flaccidis, squamis ? lanceolatis arista longissima 

 serralata cuspidatis perigynia (immatura) obovata valide costata

Fseroe ! Lyngbye. 



Non nisi dua specimina incompleta et male conservata in 

 lierbario Hornemanni exstant, quarnm alternm spicas 2 3 babet 

 $ 2, alteram femineas 6, terminali basi flore masculo unico 

 (v. 2 ?) instracta, Rad. deest (in Hornem. Plantel. 1. c. fibrosa 

 dicitur, vix reete ! sine dubio affinium more stolonifera vaginata). 

 Peduncu]i gracillini flaccidi infimus supra basin et extra 

 vaginulam ocrea atro-sanguinea instructus. Spicae lineares 

 elongate. Squama? atroviolaeese. Bractea infima vaginulata 

 culmum superans, superiores longitudine decrescunt. Peri- 

 gynia immatura obovato-cuneata griseo-fusca. 



A C. filipendula facile distinguitur aristis longissimis serrulatis. 

 C. maritima Muell. jam colore lutescente dignoscitur. C. salina 

 flaccidis rarifloris ; squamis ovatis acutis mucronatis perigynia 

 obsolete nervosis. C. crinita Lam. distincta est colore viridi, peri- 

 gyniis enerviis vel (ex Kunth) binervibus. C. macrochceta C. A. 

 Mey. (Cyp. nov. t. 13) amnior videtur. sed bene differt perigyniis 

 obsolete nervosis superne hispidis. aristis etiam longioribus, 

 pedunculis brevioribus. spicis non nisi ternis. Nostra species 

 a CI. Kunth (Cyperogr. p. 523) satis infauste ponitur in^er 

 species quoad stylorum numerum incognitas, citatis tamen 

 fig*ura fl. D. quae stigmata bina clare ostendit, et diagnosi Horn- 

 emanni ' ' stigmatibus binis ! ' ' addita insuper interrogatione : 

 "an forma distyla C. frigidce?" 



The species has since been collected by Chr. Jensen 

 and E. Rostrup, and is said to be rather rare on meadows 

 by the sea, often associated with C. salina* and the 

 C salina "Wahlenb. of the Faroe Islands is the robust 

 var. Kattengatensis Fr.
