variety of reasons, we do not find many of our native 

 jDlants becoming weeds on arable land, but from this 

 plant's vigorous, and copious seed-producing propensity, 

 and being able to withstand, unlike many other native 

 plants, the drastic treatment meted out to the soil by 

 farm implements, it bids fair to become a healthy rival 

 to weeds of Continental origin, that farmers have to con- 

 tend with, but, behig an annual, it calls for no alarm, 

 because rotation of crops and thorough and systematic cul- 

 tivation should effectually dislodge it. 



Carex bichenoviana, Boott. 



This sedge was found by the writer in a damp situar 

 tion, near the pinnacle of Mt. Direction, in the proximity 

 01 Risdon, during the earl}- summer of 1911. Mr. Rodway 

 included the description thereof in his "Tasmanian Flora," 

 but added the footnote "Inserted from record only. Doubt- 

 ful." The finding of this specimen will now remove the 

 doubt.
