Pappophorum commune, F. v. Mueller. 



Widely dispersed over the continent of Australia, also in. some 

 parts of Asia and Africa. Perennial ; regarded as a very fattening 

 pasture grass, and available for arid localities. 



Parinarium Nonda, F. v. Mueller. 



The Nonda Tree of North-East Australia. It may prove hardy in 

 temperate climes, and may live perhaps in the dry and hot air of 

 deserts, where it deserves trial culture 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 Video. A thorny shrub, clearly adapted 

 for the warmer temperate zone, where it might be utilized with the 

 following plant for evergreen hedges. The flowers are handsome. 



Parkinsonia Africana, Bonder.

 Torr., occurs on the Colorado. 



Parrotia Jacquemontiana, Decaisne. 



North-Western Himalayas, from about 3,000 to 8,500 feet eleva- 

 tion. This deciduous-leaved small tree merits attention. 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 for a variety of economic purposes (Stewart and 

 Brandis). P. Persica (C. A. Meyer) occurs on the Caspian Sea. 



Parthenium integrifolium, Linne.

 have come into use as a febrifuge (Houlton). 



Paspalum ciliatum, Humboldt. 



Tropical South America. A perennial and lauded cereal grass. 



Paspalum dilatatum, Poiret. 



Extra-tropical South America. Perennial, of excellent quality for 

 fodder. Mr. Bacchus found it hardy in Victoria up to a height of 

 2,000 feet. It grew in New South Wales after drought was 

 followed by heavy rains 4J feet in little more than two months. 

 It is closely allied to the Mexican P. virgatum, L. Introduced 

 into Australia like many other fodder grasses by the writer.
