DescriptionEdit description
Roots
Each plant has a large turnip-like taproot, which lies below the soil surface and serves for water storage.
Tubercles
The tubercles, about as long as wide, are closely packed and form a coarse mosaic. Exposed faces of tubercles, deeply fissured on either side of the central areolar groove, are coarsely rugose, and are often sharply angled apically; and with a lateral longitudinal furrow on each side of the tubercle, along the edge.
Flowers
These plants have a woolly crown, from which emerge bright pink-violet flowers up to 2,5-5 cm, 2 times wider than long when fully expanded. Flowers last for 3 to 4 days.
Blooming Season
October, November.
Fruits
white or green, with lots of seed.
Areoles
The areoles are up to 3 mm wide, sometimes confined to middle of tubercle faces instead of extending to tips.
