Flowers resembling the Rose; petals very fugacious, usually 
lasting only for a day; they are yellow, white, rose, and purple, 
with the claws usually of a different colour from the limbs. The 
branches are usually covered with clammy gluten. 
This order is nearly allied to Violariée, but differs from it in the 
flowers being always regular, and in the stamens being indefinite. 
It differs from Bixinee in the petals being always present, in the 
different æstivation of the petals, as well as in the albumen being 
mealy, and in the leaves never being furnished with pellucid 
dots. The common Rock-Rose gives a good idea of this order. 
The plants are all very ornamental, and are particularly well cal- 
culated for ornamenting rock-work or dry banks. The seeds of 
all retain their vegetative power for years, therefore they are 
easily introduced in a living state from any part of the world. 
The gum called Ladanum is the produce of a species of Cistus, 
it exhales a fragrant perfume when burnt, and possesses highly 
tonic and stomachic properties.
