  Orocereus doelzianus var. sericata forma cristata CACTUSPEDIA       

 


An attractive species that forms beautiful crest covered in long, white, hair-like spines (which becomes more dense in strong light)
 

Description: Bright green stems with blunt ribs that protrude less than 1 cm and are slightly prominent where the areoles are borne.
Areoles: circular, greyish-white and felted, separated by slight depressions,
Spines: stems are covered in long, white, hair-like spines (which becomes more dense in strong light) to protect them from the mountain cold and hot sun. Hidden in this white down are long, needle-like spines straw-coloured.

NOTE: This plant was previously included in the segregate genus Morawetzia (Backeb.) that differ from Oreocereus because of the apical cephalium consisting of hairs and bristles and becoming clavate at the apex. Flowers arise from this cephalium.
