saceis distantibus, squamis lanceolatis, capsulis subglobosis 

 inflatis setaceo-rostratis divergentibus, culmo obtusangulo, 

 foliis subangustis marginibus incurvis." — Wahl. no. 125. 



The following description is from Willd. Sp. PI. — 

 Staminate spikes three — pistillate spikes cylindric, erect, on 

 short peduncles — -fruit sub-globose, inflated, with the beak 

 bifurcate, greater than the lanceolate scale. 



This is the C. vesicaria of Lightfoot in Fl. Scot., and 

 may be mistaken for C. vesicaria L., which is credited to 

 our country and described by Ph. Muh. &z;c. But they are 

 entirely different plants. The reference in Muh. to the 

 fig. in Schk. is evidently an error of the press ; it should be 

 made to fig. 106, and not to 166. Both plants inhabit 

 marshes, but they are readily distinguished by their fruit 

 and scales. C. ampullacea has an inflated, sub-globular 

 fruit with an attenuated beak, longer than its lanceolate scale. 

 C. vesicaria, L. has an inflated, ovate-oblong, acuminate- 

 subulate fruit, scarcely longer than the scale. Both plants 

 belong to the same subdivision in Ph. &c.

C. "Spicis pedunculatis subcylindraceis nutantibus, 

 brae eis subamplectentibus subfoliaceis subdistantibus, cap- 

 sulis ovali-ellipticis obtusissimis teretibus." — Wahl.no. 121. 



The following account, translated from the Car. Scan, of 

 Agardh, was taken from living specimens. 



"Culm erect, a foot high, three sided, sulcate, leafy at 

 the base. Bracts scarcely sheathing, often transversely 

 rugose. Staminate spike lanceolate. Pistillate spikes three, 

 ovate, obtuse, pale. Scales ovate, carinate, yellowish with 

 a green keel. Capsules pale green and long as the scales." 



Our plant agrees with the preceding description and with 

 the fig. in Schk. except in one particular. The scales are 

 generally shorter than the fruit. In some specimens how- 

 ever, they agree minutely with specimens from Sweden. 

 The leaves and sheathes are slightly pilose, as are those 

 which I have from Sweden and England. The bracts are 

 often transversely rugose. The inconstant difference in the 

 scales it shares in common with C pseudo-cyperus L , 

 which Muh. considered the same with the plant so called 

 in our country, though he remarked the difference in the
