ORDER XCV1IL LORANTHACE^I. 



Parasitical shrubs, many of the tropical species with 

 brilliantly-coloured flowers. Leaves simple, entire, opposite 

 or alternate, fleshy or coriaceous, veins immersed. Flowers 

 hermaphrodite or unisexual. Perianth of 4 or more free or 

 united segments, with as many stamens as segments, and 

 opposite to them. Fruit baccate, inferior, succulent, 1 -celled, 

 1-seeded. There are 13 genera and about 450 species known, 

 chiefly tropical, and more abundant in the temperate regions

 greenish yellow, unisexual, appearing in April or May. This 

 plant is confined to England and Wales in the British Islands. 

 Viscus or Viscum is the Latin for birdlime. The application 

 will be apparent from the sticky nature of the berries. 



Lordnthus Europceus is the only other member of this 

 order occurring in Europe.
