F. microstachya (Triodia microstachya, R. Br. Prod. 182) may 

 notwithstanding its peculiar inflorescence and the extreme shortness 

 of the teeth of the glumellse prove merely a variety of F. viscida. 

 It also occurs towards the sources of the Victoria-River. 



Triodia Kerguelensis (J. Hook. Flor. Antarctic, ii. 379, tab. 138) 

 and T. antarctica (J. Hook. 1. c. 380) are like the above-mentioned 

 Triodise referable to Festuca, and for these the appellations F. Ker- 

 guelensis and F. antipoda may be adopted. 



Agrostis Solandri.

On moist ground of Chatham-Island. 



In Australia widely dispersed through the extratropical tracts. 



The adoption of a new specific name for this grass needs hardly 

 an explanation. R. Brown expressively excluded from A. Billardierii 

 Forster's plant, and like all subsequent authors did neither this 

 illustrious observer recognize in Australia its true limits, which even 

 now in the given synonymy are but imperfectly circumscribed. 

 Gmelin's and Poiret's names are apt to impress a wrong notion of 

 the plant. Under such circumstances it was deemed advisable to 

 bestow on this grass the name of the distinguished companion of Sir 

 Jos. Banks, who not only was the first discoverer of this species, but 

 who also at once recognized its true generic position, although he 

 again adopted for it more than one specific appellation. 



The habit and leaves of this grass are almost as vacillate as 

 those of Poa Australis or Danthonia penicillata. The penicillar 

 rudiment of a second flower is very variable in length and often 

 especially in small-flowered individuals reduced to a minute beard.
