THE CLASSIFICATION OF PLANTS 281 



Properties of Liliaceae. Many of the plants in this order are poison- 

 ous, and a few are used in medicine. The principal poisonous plants 

 are 



Meadow Saffron (CW<72zV;;/ autumnah}. This plant possesses a sub- 

 terranean tuber, which gives rise to rose-coloured flowers, which appear 

 in August and September ; the fruit and leaves follow in spring. The 

 whole plant is poisonous, but the seeds and tubers contain the largest 

 quantity of the poisonous material. 



Herb Paris \P. quadrifolid] and Lily of the Valley (Convallaria 

 majalis}) are also poisonous. 



Tulip (Tulipa]. The bulbs of the Tulip are poisonous, and also the 

 bulbs of Crown Imperial (Fritillaria imperialis}. 



Natural Order : Amaryllideae (Daffodil Family). These 

 plants have the same characters as the Liliaceae, with the excep- 

 tion of the pistil, which is inferior. Many of the members of 

 this order have a well developed corona, which is an outgrowth 

 of the perianth. 



Floral formula.- [P(3 + 3) A3 + 3]G(5;. 



Plants belonging to Amaryllidese. The plants of this 

 order do not need any special description, they are so much 

 like the Liliacese in every respect except the pistil. Well known 

 plants from among the Amaryllideas are the Daffodil or Lent 

 Lily (Narcissus Pseudo-narcissus}, and the Snow-drop 

 (Galanthus nivalis}, Snow-Flake (Leucojum cestwuni).
