Description
editEchinopsis chrysantha grows solitary. The depressed spherical to short cylindrical, dull grey-green shoots have a diameter of 6 to 7 cm (2.4 to 2.8 in) and a growth height of 4 to 6 cm (1.6 to 2.4 in). The shoots form an enlarged, carrot-like taproot. There are eight to twelve (rarely up to 26) straight or slightly oblique ribs that are slightly bumpy. The areoles on it are about 1.5 cm (0.59 in) apart. Reddish-brown spines emerge from them, which turn gray with age. Central spines are not formed. The five to seven (rarely from three) laterally radiating radial spines have a length of up to 2 cm (0.79 in).
The broad, funnel-shaped flowers appear laterally on the shoots and open during the day. They are yellow to orange with a darker reddish purple throat. The flowers are up to 5 cm (2.0 in) long.[3]
Distribution
editEchinopsis chrysantha is widespread in the Argentine province of Salta in the Quebrada del Toro at altitudes of 2000 to 3000 meters.
