A monogi'apli of the species of Cistus growing in the South 

 of France. The author remarks a character serving to distin- 

 guish hybi'id from true species. According to his observations, 

 the leaves of the branches of hybrids put out in spring, assume 

 the form of those of the male parent, while those borne by the 

 summer branches resemble the leaves of the female. In true 

 species, the leaves are alike in both seasons. 



M. T.-Lagrave is of opinion that hybrid plants are more com- 

 mon than has been generally believed, and that many of these 

 are fertile, reproducing themselves, though not without more or 

 less of a return to one of the parent species, tln-ough several 

 generations. His observations rest chiefly upon Cistus Monspe- 

 liensis, L., C. laurifolius, L., and O. salviaefolius, L. Minute 

 descriptions are given, with synonymy of the various forms, 

 groiiped under the heads of — 1. Plants reproducing themselves 

 precisely from seed ; and, 2. Plants which do not exactly repro- 

 duce themselves from seed — crossed or hybrid species. Of these 

 latter are Cistus albido-crispus, C. crispo-albidus, C. salviaefoHo- 

 popuUfolius, C. populifolio-salviaefolius, G. Monspeliensi-popvli- 

 folius, C. salviaefolio-Monspeliensis, C. Monspeliensi-salviaefolius, 

 G. laurifolio-monspeliensis, G alhido-monspeliensis. Other hybrid 

 Cistuses are formed between G. laurifolius, C. ladaniferus, and 

 species crossing with them. In concluding, the author groups the 

 forms of Cistus under species and hybrid-species. The former he 

 states to be common, and represented by numerous individuals ; 

 the latter rare, scattered, and always in few examples. That the 

 first reproduce themselves precisely in every mode, especially by 

 seed ; while the latter vary with each evolution, presenting a 

 tendency towards one of the parents.
