Nine of the ten species which have been recorded of this 
genus belong either to the south of Europe, the Levant, 
Coast of Barbary, Egypt, or Arabia. The present is indi- 
genous of the Canary Islands, and was introduced by Mr. 
Francis Masson in 1780. It has not been represented by 
any published figure; and was by no means a common 
plant in our collections. We were favoured with the speci- 
men by Mr. Biggs, the Curator of the Botanic Garden at 
Cambridge. } 
The type of this genus does not seem to have been ob- 
served in any part of the New World.
