The Rock Rose which forms the subject of our figure is 
one which has been grown in the Kew collection for a 
quarter of a century, but having been received under 
another name and having since its receipt been ‘several 
times propagated its origin is not known. That it is a 
natural hybrid between Cistus ladaniferus, Linn., figured 
long ago at t. 112 of this work, and C. monspeliensis, Linn., 
has long been believed, for it has been met with in a wild 
state in Hérault growing along with the two parent species. 
The belief has been confirmed by the late Mr. Bornet, who 
obtained C. Loreti experimentally by crossing these two 
species. The special interest of this Rock Rose to 
cultivators lies, however, in the fact that it is one of the 
hardiest in the genus; it has withstecd at Kew without injury,
