When cultivated in Great Britain, Ricinuscommunis is an annual, seldom exceeding three or fourfeet high ; but in other parts of the world it is said to beperennial, arborescent, and to attain a height of fifteen or u^<./twenty feet. Dr. Roxburgh (Ft. Indica, vol. iii. p. 6S9) V \ says, that in India several varieties are cultivated, some Ricinus communis. of them growing to the size of a pretty large tree, and of. 232 ELEMENTS OF MATERIA MEDICA. many years duration. Clusius {Exoticorum, p. 299) saw it in Spain with abranched trunk as thick as a mans body, and of the height of three men. Belon(Observ. lib. i. cap. 18) also tells us that in Crete it endures for many years,and requires the use of ladders to mount it. Ray {Hist. Plant, vol. i. p. 160)found it in Sicily as large as our common alder trees, woody, and long-lived;but it has been a question with botanists, whether these arborescent and otherkinds are mere varieties of, or distinct species from, the ordinary Ricinus com-munis. The following (varieties or distinct species) are enumerated by Nees and Ebermaier ( Med. Pharm. Botan.) as common in gardens, and as distinguished principally by the colourand pruinose condition of the stem—characters which, however uncertain in other cases, appearhere to be constant. 1.
