Description
It in a nice selected form with only three ribs.
Flowers
Arise from the areole at the tip of the stem on mature plant (at least 4-5 years old) they are large, funnel-shaped, yellow with a red throat, 5-7 cm wide.
Blooming Season
Flowers intermittently throughout the warm months from spring to autumn.
Stem
Covered with dense white flecks. This cultivar tends to be unstable, and some of the three ribbed specimens develop additional ribs as they age. Old and big plants which maintain the typical three ribbed shape are very very prized.
