SELECT PLANTS FOR INDUSTRIAL CULTURE 



Psidium lineatifolium, Persoon. 



Mountains of Brazil. Berry about 1 inch diameter. 



Psidium malifolium, F. v. Mueller. (Oampomanesiam 

 Uruguay. Berry about 1 inch diameter. 



Psidium polycarpon, Al. Anderson.* 



From Guiana to Brazil, also in Trinidad. A comparatively small 

 shrub, bearing prolifically and almost continuously its yellow 

 berries, which are of the size of a large cherry, and of exquisite 

 taste. 



Psidium rufum, Martius. 



Brazil, in the province of Minas Geraes, on Sub- Alpine heights. 

 This Guava-bush gains finally a height of 10 feet, and is likely the 

 hardiest of all the species producing palatable fruit. 



Psoralea esculenta, Pursch. 



North America. This herb is mentioned here, as the tuberous roots 

 known as Prairie Turnips may by cultural processes be capable of 

 great improvement, and of thus becoming a valuable esculent. 



Psychotria Eckloniana, F. v. Mueller. (Grumilia cymosa, E. 

 Meyer.) 



South Africa. Dr. Pappe describes the wood of this tree as 

 beautifully citron-yellow. 



Pterocarpus Indicus, Roxburgh. 



The Lingo of China and India. A tree of considerable dimensions, 

 famed for its flame-red wood. It furnishes also a kind of dragon- 

 blood resin. 



Pterocarpus Marsupium, Roxburgh. 



India, ascending in Ceylon and the Circars to at least 3,000 feet 

 altitude ; hence this tree would doubtless grow without protection 

 in those tracts of the temperate zone which are free from frost. 

 It exudes the best medicinal kino, which contains about 75 per 

 cent, of tannic acid. The foliage is deciduous. P. santalinus 

 (Linne fil.), which provides the Saunders or Red Sandal Wood, is 

 also indigenous to the mountains of India, and important for dye- 

 purposes in cultures of Japan. 



Pterocarya fraxinifolia, Kunth. 



From Central Asiatic Russia to Persia. A kind of Walnut-tree, 

 which, with P. stenoptera (Cas. de Cand.), on Dr. Ilance's 

 recommendation, should be adopted as trees for both ornament and 

 timber, and so perhaps also the Japanese species.
