 some parts of Asia and Africa. Perennial; regarded as a 

 very fattening pasture-gi'ass, and available for arid localities. 



Parinarium Nonda, F. von Mueller. 



The Nonda-tree of North-East Australia. It may prove 

 hardy in East Gipps Land, and may live perhaps in the dry 

 and hot air of our desei-ts, where it deserves trial-cultm-e for 

 the sake of its edible mealy plum-like fruit. A few other 

 species with esculent drupes occur in different tropical 

 countries. 



Parkinsonia aculeata, Linne. 



From California to Monte Yideo. A thorny shrub, clearly 

 adapted for the warmer parts of Victoria, where it might be

 herb have come into use as a febrifuge (Houlton). 



Parrotia Jacquemontiana, Decaisne. 



North Western Himalayas, from about 3000 to 8500 feet 

 elevation. This deciduous-leaved small tree merits intro- 

 duction. Its tough and pliable twigs are used for basket- 

 work and preferentially for the twig-bridges, the latter up to 

 300 feet long ; hence this tree could be used here for a 

 variety of economic purposes (Stewart and Brandis).

Paspalum ciliatum, Humboldt. 



Tropical South America. A perennial and lauded cereal grass.
