252 Select Plants for Industrial Culture 



Pappea Capensis, Ecklon and Zeyher. 



South-Africa. The fruit of this tree is of the size of a cherry, 

 savory and edible. The seeds furnish an oil similar to castor-oil in 

 its effects (Prof. McOwan). 



Pappophonim commune, F. v. Mueller. 



Widely dispersed over the continent of Australia, occurring also 

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

 fattening pasture-grass, and available for arid localities and almost 

 rainless zones. 



Parinarium Nonda. F. v. Mueller. 



The " Nonda-tree " of North-Eastern Australia. Attains a height 

 of 60 feet; its wood soft, close-grained, easily worked (W. Hill). 

 May prove hardy in mild temperate climes, and may perhaps live 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 Uruguay. A thorny shrub, clearly adapted for 

 the warmer regions of the temperate zone, where it might be utilized 

 with the following plant for evergreen hedges. The flowers are 

 handsome. Six other species occur in various parts of America. 



Parkinsonia Africana, Sender. 

 South- Africa. A tall bush. ' 



Parrotia Jacquemontiana, Decaisne. 



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

 This deciduous-leaved small tree merits attention. Its tough and 

 pliable twigs are used for basket-work and preferable for the twig- 

 bridges, the latter sometimes 300 feet long; hence this tree could be 

 used for a variety of economic purposes (Stewart and Brand is). P^ 

 persica (C. A. Meyer) occurs on the Caspian Sea. 



Parthenium integrifolium, Linne". 



Eastern North- America. The flowering tops of this perennial 

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



Paspalum ciliatum, Humboldt. 



Tropical South- America. A perennial and lauded cereal grass. 



Paspalum dilatatum, Poiret. (P. ovatum, Trinius.) 



North- and South-America. Perennial; of excellent quality for 

 fodder; keeps green during the hottest summer-time. Mr. Bacchus 

 found it hardy up to a height of 2,000 feet in Victoria. It grew 4^. 

 feet in little more than two months in New South Wales, after drought 

 was followed by heavy rains. It is closely allied to the Mexican P^ 

 virgatum, L. Introduced into Australia by the writer with many 

 other fodder-grasses.
