Carex hcematolepis Drej. 



This interesting species has, so far, only been found in 

 South Greenland, and since several authors have identi- 

 fied a variety of C. salina as representing C. hcematolepis, 

 it may be well to reprint the original diagnosis as pre- 

 sented by Drejer (Revisio critica, p. 44).

Radix ut affinium. Culm, erectus strictus, acutangulus scab- 

 errimus v. scabriusculus. Fol. erecta latissima scaberrima. 

 Spica 5 interdum altera rudimentaria basi augetur, sa3pe quoque 

 basi feminea est (in uno specimine sp. terminalis mere feminea), 

 oblongo-clavaeformis. Squamas 5 obovato-oblongaa acutiusculas 

 muticae raro mucronatae, atrofusca3 nervo pallido. Spicas 6 

 inferiores pedunculatae, sum ma subsessilis. Bract, inferiores 

 foliacese scaberrimaB basi biauriculatae auriculis atrosanguineis 

 confluentibus amplectentibus, infima culmum subaequans, sequens 

 spicam $ subattingens, tertia setacea spica sua sublongior. Pe- 

 dunculi plerumque validi spica sua breviores, in nonnullis tamen 

 tenuiores et longiores, ocrea atrosanguinea instructi. Squamae 

 5 atro-sanguineae tenuissime punctulatae nervo tenuissimo dis- 

 color e, ovatae, acutaa serrulato-aristatae v. muticae, perigynia fere 

 tegentes et superantes. Perig. obsolete nervata decolora stra- 

 mineo-viridia, rostro brevissimo integro. Stylus brevissimns vix 

 exsertus, stigmata 2, rarius 3, longissima. Variat foliis angusti- 

 oribus, squamis & et 2 magis rotundatis, spicis ? omnibus pedun- 

 culitis, superioribus apice masculis. 



Species pulcherrima, ab altera parte C. saxatili et C. hyper- 

 borea, ab altera C. filipendula cet. affinis. A C. saxatili differt 

 spicis longius pedunculatis, magis elongatis, squamis saepe mu- 

 cronulatis, perigyniis subnervatis cet. A C. filipendula spicis 

 suberectis, rarifloris, elongatis, pedunculis semper brevioribus et 

 validioribus, squamis brevioribus, culmo scabro v. scaberrimo. 

 C. Lyngbyei, macrochmta, maritima facile dignoscuntur squamis 

 longissime aristatis. C. recta Boott (1. c. p. 220. t. 222) differt 

 spica & brevi cum femineis superioribus aequialta, culmo modo 

 superne scabro. C. aperta Boott (1. c. p. 218. t. 219) similior 

 videtur, sed differt rostro bidentato, perigynio orbiculato cet. ; 

 haec quoque a cl. autore cum C. ccespitosa comparatur, cui nostra 

 nimis dissimilis est. ' ' 



According to Drejer (1. c.) the affinity is with C. crypto- 

 carpa, and the Scandinavian plant, named C. hcematolepis 

 by certain authors, is a member of the Salines viz. C.
