For the purpose of distillation three species of the genus Pelargonium and their cultural varieties are principally cultivated, viz., Pelargonium odoratissimum, Willd.1), P. capi-tatum, Ait., and P. roseum, Willd. (family Geraniaceae). The last-named is regarded as a variety of P. Radula, Ait.2). According to L. Ducellier3), Pelargonium graveolens, Ait. (P. tere-binthinaceum, Cav.) is cultivated exclusively for the distillation of the volatile rose geranium oil.
