Distribution: South America, but not known definitely in the wild state. This species is represented in the New York Botanical Garden by a live specimen from Kc\v, which we consider typical. Salm-Dyck described it from specimens growing in the Botanical Garden at Berlin, but did not know their origin. Schumann figured what he supposed to be it in the Flora Brasiliensis, referring it to Brazil; his plant is from the Prov- ince of Rio de Janeiro, collected by Glaziou, and is undoubtedly Cephalocereus arrabiilac. ('crcus tctracanthus Labouret (: 25. 1855) and C. tcphracanthus bolivitunts Weber (Schumann, Gesamtb. Kakteen Si. 1897) are probably of this relationship; both forms come from Bolivia. Riimpler (Forster, Handb. Cact. ed. 2. 712. 1885) says the former came from Chuquisaca, Bolivia. An earlier reference (Steudel, Nom. ed. : 336. 1840), but of slightly different spelling, cites Link and Otto as authors of this name, but the species was not described. To one of these forms may belong the plant in the New York Botanical Garden (No. 6231), obtained from M. Simon, St. Ouen, Paris, in 1901, which is called Cereus bolivianus. The last name, first credited to Weber (Monatsschr. Kakteenk. 12: 21. 1902), is occasionally met in literature. Cereus hempelianusBaue
