Barren clayey limestone hills on the Arkansas, near Cauoa City, with Frankenia, several shrubby Atriplex, Juniperus occidentalism etc., where I discovered it in September, 1874; also in Southern Utah, Dr. Parry, 1874, No. 78, doubtfully referred to If. multiflora. From the large, fleshy, branching, not fusiform root rise branching stems 1- 2 feet high; leaves 1- 3 inches long, £- l£ inches wide, more or less coarsely dentate, upper ones often entire; flowers 15- 20 lines in diameter, open in the afternoon .( and evening ?); petals 6- 9 lines long, 2- 3 lines wide, often less than 10 in number, the innermost smaller and an-theriferous; ovary with three placentae, each bearing two series of ovules j capsule 3 lines wide, in some £, in others fully 1 inch long; seeds very narrowly margined, similar to those of M. Iceoicaulis, but much smaller and not winged, surface facetted. Apparently near M. pumila, as described in Torr. & Gr. Fl. N. A., 1, 535, but that species is said to have small terminal flowers and winged seeds. Name from the golden- yellow color of the flowers, by which it is easily distinguished from the different cream- white species which grow in the same region. This color, however, gradually fades in drying, or becomes brown ; this is also the case in the yellow flowers of M. Uevicaulis, while the flowers of If. oligo-sperma retain their color much better.- GEO. ENGELMANN. ECHINOCACTUS WHIPPLEI, B. & B. La Plata Valley and mesa Verde, 5,000 to 8,000 feet.
