slopes near the coast. It is considered one of the finest of 

 the Araucaria tribe, and in its native regions attains an 

 approximate height of 200 feet. The wood is utilised for 

 furniture and planking. The Bunya Bunya withstands 

 drought better than most of the genus, and flourishes 

 luxuriantly in and around Melbourne, Sydney, and Adelaide. 

 Many very fine specimens exist in the public and private 

 gardens. See also Araucaria.

 Butcher's Broom.— RUSCUS ACULEATUS. (Natural 

 Order, Liliaceje.) Pp. 31, 32. — This curious plant 

 belongs to the Asparagus tribe (AsJ>aragce), a sub-order of 

 the Liliacese. It is a great favourite in shrubberies, from its 

 compact habit, pretty angular foliage, and bright red berries. 

 It is also called the Knee Holly. 



Buttercup. — RANUNCULUS. (Natural Order, 



Raxuxculace^e.) Pp. 3, 54, 196.— A large family of herba- 

 ceous plants, principally noted for extreme acridity of root 

 and leaves, and beauty of flower in some species. They 

 are widely distributed. Some of them are aquatic plants, 

 such as the Water Celery (Ranunculus sceleratus) and Water 

 Crowsfoot {Ranunculus aquatilis), both natives of Britain. 

 The beautiful Ranunculi of the florists are varieties of 

 Ranunculus Asiaticus. The order is very common in 

 Australia. See Native Buttercup.

 Order, Iride.e.) P. 17. — This beautiful perennial bears 

 large sulphur-hued flowers, the petals having a singular dark-

 wings of a moth or butterfly. It is common in Australian 

 gardens, and is a native of the Cape of Good Hope.
