PHORMIUM. (\EW ZEALAND FLAX, 

 FLAX LILY.) 



Description. A genus of noble, ornamental, per- 

 ennial herbs (ord. Liliacese), with fine, sword-like 

 leaves, and panicles of flowers. They make hand- 

 some greenhouse plants, especially the variegated 

 forms, but several are quite hardy in many parts 

 of the United Kingdom. In the neighbourhood 

 of water they thrive well and show to great ad- 

 vantage. Young plants should be protected for 

 a few winters. 



Propagation. By seeds, sown under glass as 

 soon as ripe, or in spring, and by division in early 

 spring. 



Soil. Any good loam.

PHORODON. 



This genus of Aphides differs little from other 

 green fly in appearance. Humuli causes trouble 

 amongst the Hop fields. Entomologists are of 

 opinion that Humuli is the same insect which 

 preys upon the young growth of the Plum and 



Phoma effusa, (see Helleborux). 



Damson in spring and in September, the period 

 between being spent upon the Hop. Spraying 

 with kerosene emulsion, or one of the other insect- 

 icides recommended for aphides, is advised. A 

 forcible stream of clear water from the garden 

 engine is excellent. Ladybirds, Hawk flies, and 

 Golden-eyed flies should be encouraged. 



PHOSPHATIC MANURE. 



Phosphates of lime are the usual form in which 

 phoapfaatio manures exist, and while most soils 

 contain a quantity of these phosphates the store 

 soon becomes exhausted under heavy and con- 

 tinuous cropping. Bones and coprolites are the 

 principal sources of supply. Soluble phosphate, or 

 superphosphate, of lime is obtained by treating 

 bones with oil of vitriol (sulphuric acid), but the 

 commercial superphosphate generally contains a 

 quantity of insoluble phosphates and sulphate of 

 lime. The phosphate is nominally insoluble, but 

 becomes soluble when acted upon by the acid 

 excreted by the root hairs of plants. These 

 insoluble phosphates may be placed in the soil at 

 any convenient season ; they give up their con- 

 stituents slowly, and little of their substance is 

 washed away by heavy rains as is the case with 

 the soluble phosphates contained in commercial 

 superphosphate. The latter, however, is of the 

 utmost value where comparatively quick results 

 are desired, but it is not economy to apply it to the 

 land in autumn. (See also ARTIFICIAL MANURES 

 and MANURES.) 



PHOTINIA. (LOQUAT.) 



Half-hardy evergreen trees and shrubs (ord. 

 Rosacea?). Propagation, by cuttings of the side 

 shoots, in sand, under a bell-glass; also by cleft 

 grafting upon the common Quince, in April, the 

 stock being worked close to the ground. Soil, 

 sandy loam. The most popular species is japonica, 

 the Japan Medlar. 



Principal Species : 

 japouica, 10' to 20', hdy. 

 in sheltered places, wh. , 

 fruits or. red, small, ed- 

 ible ; should be grown

 PHRAGMATOBIA. 



This genus is included amongst a few others 

 collectively known as Tiger Moths. The Ruby 

 Tiger Moth is fuliginosa ; it is about li" in wing 

 spread, has dull reddish brown wings with two 

 black dots, a brown head and thorax, and a pink 

 abdomen. The yellowish brown larvas may be 

 seen in autumn seeking resting places for the 

 winter. They emerge in the following spring, 

 spin their cocoons in April and May, and pupate. 

 The moths make their appearance in April. 



The larv;e feed chiefly upon weeds, but in some 

 instances they attack garden produce. Hand- 

 picking is the remedy. 



PHRAGMIDIUM. 



A small genus of Funs^i, popularly known as 

 " Brands," and allied to Puccinea. Kubi - Idsei 

 is the Raspberry, and mucronatum the Rose,
