Naturalisation in Extra-Tropical Countries. 367 



Peuxnus Boldus, Molina. 



The Boldo of Chili. A 'small ornamental evergreen tree, with 

 exceedingly hard wood, which is utilised for many kinds of imple- 

 ments. The bark furnishes dye-material. The fruits are of aromatic 

 and sweet taste [Dr. Philippi]. 



Peziza macropus, Persoon. 



Europe. Mentioned by Prof. Goeppert among the edible mush- 

 rooms, sold in Silesia along with P. repanda (Wahlenberg). Dr. 

 M. C. Cooke enumerates the following Victorian species as edible : 

 P. vesiculosa, Bull. P. aurantia, Pers., P. venosa, Pers., P. cochleata, 

 Linne. 



Phacelia tanacetifolia, Bentham. 



California, Texas. Annual. A superior bee-plant of easy rear- 

 ing, successfully grown in Germany. Allied species and some other 

 hydrophyllaceous plants, all elegant and easily raised from seed, may 

 perhaps answer the same purpose. 



Phalaris aquatica, Linne. 



Southern Europe and Northern Africa. Important as a perennial 

 fodder-grass, fit for wet ground. 



Phalaris arundinacea, Linne. 



Temperate and colder regions of Europe, Asia and America ; 

 indigenous in Norway to lat. 70 30'. Not without some importance 

 as a reedy grass of bulky yield on wet meadows or in swampy 

 places. A variety with white-striped leaves is a favorite as a ribbon- 

 plant for garden-plots. 



Phalaris Canariensis, Linne. 



The Canary-grass. An annual grass from the Canary-Islands, 

 now widely dispersed as a spontaneous plant over the warmer zones 

 of the globe. Thus it has also become naturalised in Australia. It 

 will endure the climate of Norway to lat. 70 22', bearing seed to 

 lat. 63 26' [Prof. Schuebeler]. It is grown for its seeds, which 

 form one of the best kinds of food for many sorts of small cage- 

 birds. The flour is utilised in certain processes of cotton-manufac- 

 ture, and liked even for some kinds of cakes. The soil for culture 

 of the Canary-grass must be friable and not too poor, and the crop 

 must be kept out of the reach of grain-feeding birds, so that it is advis- 

 able to grow it only on widely cleared ground. One-third bushel of 

 seeds suffices for an acre. It is an exhaustive crop. 'Chemical consti- 

 tuents here (in November) : Albumen 1'59, gluten 6' 14, starch T03, 

 gum 6 '64, sugar 2'86 per cent. (F. v. Mueller and L. Rummel); another 

 analysis in the same month gave : Albumen 1*06, gluten 5*64, starch 

 0'98, gum 3-22, sugar 4*20 per cent. Import of seeds during 1887
