FERONIA. 



A stove evergreen tree (iml. Rutacese) chiefly 

 grown for its fruits, known as Elephant Apples 



FERTILISATION. 



The fusion of the male and female elements pro- 

 duced by the flowers, hence the result of pollina- 

 tion, or the deposition of the pollen upon the 

 stigma of the pistil. 



Fertilisation is brought about in a variety of 

 ways. It may be (1) natural, or (2) artificial. 

 Artificial pollination becomes necessary with 

 cultivated plants that are grown out of their 

 natural season. Thus Peaches under glass which 

 flower early in the year have to be " brushed " by 

 hand because the bees that would perform the 

 work later in the year are still in the enjoyment of 

 their winter rest. A very light touch is sufficient

or Wood Apples. Both leaves and flowers are 

 fragrant. Propagation, by cuttings of firm shoots 

 in spring. Peaty soil. 

 Principal Species :

FERRARIA. 



Quaint and interesting greenhouse, bulbous 

 plants (urd. Iridese). Increased by offsets or seeds. 

 Soil, peat or leaf mould, loam, and sand. In 

 favoured districts they may be grown out of dours 

 on a well-drained, sheltered border.

ID transfer the pollen; if the operator is heavy, 

 handed the tender organs are bruised, decay 

 ensues, and the prospects of fruit vanish. With 

 Tomatoes and Vines a slight tap given to the 

 stems of the plants at midday is usually sufficient. 

 Melons must be fertilised ; Cucumbers need not. 

 Unfertilised Cucumbers contain no seeds, but this 

 is really an advantage for culinary purposes. 



FERULA. (GIANT FUNNEL.) 



Handsome herbaceous plants (itrd. Umbellifera:) 

 with graceful foliage. Foetida yields the Asa- 

 fcetida of commerce, and the juice of the root of 

 Sumbul is also used medicinally. Propagation, by 

 division in spring, or by seeds sown, preferably 

 under glass, at the same season. Any common 

 soil, preferably rather damp.
