Pterocarpus Indicus, Roxbui-gli. 



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 Cii'cars to at least 3000 

 feet altitude ; hence this tree would doubtless grow without 

 protection in those tracts of our colony, which are free of 

 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. 



Pterocarya fraxinifolia, Kunth. 



From Central Asiatic Kussia to Persia. A kind of Walnut- 

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

 recommendation, should be adopted as trees for both ornament 

 and timber, and so perhaps also the J apanese species. 



Ptychosperma Alexandrae, F. v. Mueller. 



The Alexandra-Palm. Queensland, as well in tropical as 

 extra-tropical latitudes. The tallest of Australian Palms, 

 and one of the noblest forms in the whole empire of vegeta- 

 tion. It exceeds 100 feet in height, and is likely destined to 

 grace any shady moist grove free from frost in this and other 

 countries, as it seems less tender than most palms. The 

 demand for seeds has already been enormous. 



Ptychosperma Cunninghami, Hermann Wendland. 



East Australia, as far south as Illawarra; thus one of the 

 most southern of all Palms. This also is a very high species, 

 destined to take here a prominent position in decorative plan- 

 tations. Several species occur in Fiji and other islands of the 

 Pacific Ocean, and again others might be obtained from India, 

 but they are probably not so hardy as ours. Though strictly 

 speaking of no industrial value, these Palms are important 

 for horticultural trade, and are objects eminently fitted for 

 experiments in acclimation. 



Ptychosperma disticha, Miquel. (Areca disticlm, Griffith.) 

 Assam, up to 4000 feet. 



Ptychosperma elegans, Blume. {P. Seaforthia, Miquel ; 

 Seaforthia elegans, P. Brown.) 

 Littoral forests of tropical Australia. Also a lofty magnifi- 

 cent Feather-Palm. Its leaflets are erose. It may prove 

 hardy. 



Pueraria tuberosa, Candolle. 



SoTitli Asia, up to 4000 feet. A tall woody twiner. Its 

 large tubers are edible and might improve by culture.
