Number VII in this series covered the survey of the first 1000 plant accessions (I), and number XI1 the second 1000 (2). The present report is a continuation of these and covers the third 1000. Paper VII should be consulted for background, methods, and objectives. T h e data include the kinds and amounts of steroidal sapogenins found, and the results of qualitative tests for saponins, flavonoids, alkaloids, tannins, and unsaturated sterols. There are 954 lots of plant material, representing 606 identified species, 160 lots identified as to genus only, 348 genera, and 96 families. There are 21 families, 225 genera, and 513 species not found i n the first two lists. T o date, one or more species in 693 genera, representing 157 families, have been analyzed. There is no published chemical information o n about 50 per cent of the species examined. B E C A U S E of an increased interest in hecogenin as a possible source of cortisone, a greater emphasis was placed on collecting as many species of agave as was possible. These collections were obtained by Gentry mainly from northern Mexico especially in Baja California. Besides random collecting of species of agave, large repeat samples
