Echinopsis chrysantha, is a species of Echinopsis found in Argentina.[2]
Description
Echinopsis chrysantha grows solitary. The depressed spherical to short cylindrical, dull grey-green shoots have a diameter of 6 to 7 centimeters and a growth height of 4 to 6 centimeters. 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 centimeters 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 centimeters.
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 centimeters long.[3]
Distribution
Echinopsis chrysantha is widespread in the Argentine province of Salta in the Quebrada del Toro at altitudes of 2000 to 3000 meters.
