ISI 2013-3. Echinopsis densispina Out of Stock Werdermann

Originally described as having yellow flowers, E. densispina populations vary somewhat in flower color and spination. As a result, a number of names have been published that are now considered synonyms. One of these is Lobivia chlorogona, the name under which our plants were received. The dark central spines are said to number from 4 to 7, but in our plants are lacking or solitary and are inconspicuous against the more numerous radials which are pectinate and silvery to russet. The globular bodies are solitary or clumping and lie close to the ground atop tuberous roots that can be as large as the stems. Flowers in our offering are mostly in shades of orange with paler outer tepals and have a light-colored ring in the throat formed by the fused filament bases. Our plants, HBG 118290, were grown from seed of material originally collected by Friedrich Ritter, FR 403, at Volcán, in Jujuy Province, Argentina, along the west flanks of the Sierra de Tilcara, in the Humahuaca Valley. $8.
