Pimpinella Sisarum, Benth. (Sium Sisarum, L.) 



East Asia. A perennial herb. The bunches of small tubers 

 afford an excellent culinary vegetable. 



Pipturus propinquus, Weddell. 



Insular India, South Sea Islands and warmer parts of East 

 Australia. This bush is higher and rather more hardy than 

 Boehmeria nivea ; but in fibre it is similar to that plant. 

 P. velutinus, "Wedd., is closely allied. The few other species 

 serve probably as well for fibre. 



Pistacia Lentiscus, L. 



The Mastix Tree. Mediterranean regions. A tall ever- 

 green bush, exuding the Mastix Resin mostly through 

 incisions into its bark. In Morocco it is extensively used 

 for hedges. 



Pistacia Terebinthus, L. 



Countries around the Mediterranean Sea. A tall bush or 

 small tree with deciduous foliage. The fragrant Cyprian or 

 Chio Turpentine exudes from the stem of this species. 

 P. vera, L., is inserted already among the timber trees. 



Pisum sativum, L.* 



The Common Pea. Mediterranean countries and "Western 

 Asia. This annual of daily use could hardly be left disregarded 

 on this occasion. Suffice it to say, that the herbage as a 

 nutritious fodder deserves more attention than it receives. 

 The green fruit contains Inosit-sugar and Cholesterin-fat. 

 A second species, P. Aucheri, Jaub. and Spach., which is 

 perennial, occurs in alpine elevations on the Taurus. 



Plectocomia Himalaiana, Griffith. 



Sikkim, up to 7000 feet. This Rattan-Palm requires moist 

 forest-land. Its canes are not durable, but this palm is an 

 object worthy of horticulture and would prove the hardiest 

 among its congeners. 



Poa anglistifolia, 1^. (-P. serotina, Ehrh. P. fertilis, Host.) 

 Europe, North Asia, North America. A perennial pasture- 

 grass, allied to P. nemoralis. An excellent grass for moist 

 meadows and river-banks.
