NOTES ON SOME HERTFORDSHIRE CARICES. 

 Bt R. A. Prtoe, B.A., F.L.S. 



In tbe preparation of tbe Flora on whicb I am engaged, I have 

 found it necessary to pay considerable attention, among other doubtful 

 points, to those connected with some of our more interesting Carices. 

 The following notes are based on the examination of a number of 

 specimens preserved in the collection of the late Rev. W. H. Cole- 

 man and in other herbaria, but more especially in the growing 

 state. 

 Car ex lepidocarpa, Tausch. 



After some consideration and the comparison of numerous examj Ips 

 from different parts, I have come to the conclusion that we have but 

 one form of C. flava in the county, and have little hesitation in re- 

 ducing both the '^ flava " and " OEderi " of the *' Flora Hertfordiensis " 

 to C. lepidocarpa, Tausch. Variable as this sedge is in appearance, 

 and ranging from eighteen to barely three inches in height, it can, I 

 believe, be readily recognised, at all events in the living state. Be- 

 sides the usually longer-stalked male spikelet, and the roughness of 

 the upper part of tbe stem, the perigynia are generally not above half 

 the size of those of C. jlava, and the shorter beaks are either almost 

 straight, or have rather the appearance of having been forcibly bent 

 downwards, instead ot the natural and almost double curvature of 

 those of the genuine plant.
