CISTACE,E. 



[Hypogynous Exogens. 



Theads except in its indefinite stamens. An anonymous writer in the Linncea, whose 

 views are often judicious, would place the Rock Roses in the neighbourhood of Mesem- 

 bryacese, Nyctaginacere, and Polygonacese, and next Portulacacese : an opinion evidently 

 formed upon the supposed importance of a curved embryo and mealy albumen. 



South Europe and the north of Africa are the countries that Rock Roses chiefly inhabit. 

 They are rare in North America, extremely uncommon in South America, and scarcely 

 known in Asia. 



The species have no marked properties, except that the resinous balsamic substance, 

 called Ladanum, is obtained from Cistus creticus, and others ; it has been much 

 esteemed as a stimulant and emmenagogue ; it has also been recommended in chronic 

 catarrh. Helianthemum vulgare had once some reputation as a vulnerary, but it is now 

 forgotten. The trunk of Cochlospermum Gossypium yields the gum Kuteera, which in 

 the north-western provinces of India is substituted for Tragacanth. — Boyle. A decoc- 

 tion of the roots of Cochlospermum insigne, called in Brazil Butua do curvo, is em- 

 ployed in internal pains, especially such as are produced by falls or accidents ; it is also 

 asserted to heal abscesses already commenced C. tinctorium is used in cases of 

 amenorrhoea, and also as a yellow dye.

M. Planchon separates Cochlospermum as the type of an order which he calls 

 Cochlosperme.e, and which he conceives to be more allied to Zygophyls and 

 Cranesbills ; and he refers to the order the genus Amoreuxia, or Euryanthe. (See 

 London Journal of Botany, VI. 301). I am not, however, prepared to remove 

 these plants from the neighbourhood of Cistacese, where they now stand. The 

 following is the little groupe which M. Planchon proposes.
