Native. Paludal. An unsatisfactory species, very im- 

 perfectly known to British botanists, and often repre- 

 sented in herbaria by specimens of C. acuta or C. vulgaris. 

 I have seen examples from the counties of Norfolk (Miss 

 Bell), Cambridge (Rev. James Harris), Salop (Mr. T. B. 

 Bell, Bot. Soc. Ed.), Chester and Lancaster (H. C. Wat- 

 son), which appear to me correctly thus named. But the 

 Scottish specimens which I have seen labelled as C. 

 stricta, from the Edinburgh Society and from individual 

 botanists of Edinburgh, appear to my eyes to belong to 

 C. acuta. C. stricta is included by name in the manu- 

 script Flora of Orkney, by Dr. Gillies, on liis individual 

 authority ; but a specimen so named among the Orkney 

 plants, several times before mentioned as probably col- 

 lected and labelled by Dr. Gillies, is ceitainly C. vulgaris. 

 In how many of the English counties C. stricta (Good.) 

 reaUy has been found, I am quite unprepared to say. It 

 is reported from 21 or 22, some of them likely to prove 

 errors. We have Mr. Borrer's authority for its occur- 

 rence so far north as Westmoreland. According to Sir 

 Walter Trevelyan's list, it occurs in Faroe.
