Naturalisation in Extra-Tropical Countries. 163 



Danthonia bipartita, F. v. Mueller. 



From the interior of New South Wales and Queensland to West- 

 Australia. Available as a tender-leaved and productive perennial 

 grass, particularly for any desert-regions. 



Danthonia Cunningham!, J. Hooker. 



New Zealand. An alpine fodder-grass, with large panicles ; it 

 attains a height of 5 feet, and forms tussocks. Pasture-animals 

 relish the young foliage and the flower-masses [J. Buchanan]. 



Danthonia nervosa, J. Hooker. (Amphibromus Neesii, Steudel.) 



Extra-tropical Australia. One of the best perennial nutritious 

 Swamp-grasses. 



Danthonia nuda, J. Hooker. (D. Thomsoni, Buchanan. , 



New Zealand. A grass of lowlands and sub-alpine localities. 

 Yields a large amount of fine herbage of very nutritious quality. 

 Holds the ground well and thrives in dry sheltered situations [D. 

 Petrie]. 



Danthonia penicillata, F. v. Mueller.* 



The Wallaby-grass. Extra-tropical Australia and New Zealand, 

 ascending to alpine elevations. Variable in its forms. Mr. A. N. 

 Grant mentions this as the most gregarious of grasses in Riverina, 

 though after seeding early in summer it becomes parched, until it 

 pushes afresh after the first autumnal rains. It is most easily dis- 

 seminated. Dr. Curl found this perennial grass useful for artificial 

 mixed pasture in New Zealand. Its principal value is in spring. 

 Noted as very valuable in its native localities. Deserving of methodic 

 rearing. Will live where cocks-foot and rye-grass succumb for want 

 of humidity or nourishment [Th. Mason]. 



Danthonia robusta, F. v. Mueller. 



Australian Alps. Forms large patches of rich forage near or at 

 the very edge of glaciers, and may therefore possibly endure the 

 winters of Middle Europe. The tall D. rigida (Raoul) of New 

 Zealand is closely allied. Prof. Hieronymus mentions D. picta 

 (Nees) as a superior grass of extra-tropic South- America for sheep- 

 pastures. 



Datisca cannabina, Linne". 



From Greece to Upper India. A perennial herb ; the leaves and 

 roots are used in medicine, and also yield a superior yellow dye.
