Family: Cactaceae (Cactus Family)

Scientific name:  Echinofossulocactus phyllacanthus (A. Dietrich et Otto) Lawrence 18

Habitat: This species grows and hides in high grass, and the spines that looks like dried grass leaves, make the plants almost invisible in their natural environment.

Etymology: The specific epithet "phyllacanthus" (leaf-spine) derives from the greek words “phyllon” (φυλλον) = leaf and “acantha” (ακανθα) = spine.

  • Stenocactus phyllacanthus (A. Dietrich et Otto) A. Berger ex A. W. Hill 1933, (Mexico)

  • Ferocactus phyllacanthus (A. Dietrich et Otto) N. P. Taylor 1980

  • Efossus phyllacanthus
  • Echinofossulocactus tricuspidatus (Scheidweiler) Britton et Rose 1922

  • Stenocactus tricuspidatus (Scheidweiler) A. Berger 1929
 


Cultivation:
Easy to to care and flower. No absolute schedule can be given for watering as  various factors (Soil mixture, containers, drainage, temperature, size of plant) influence water use, so  - as a general rule - the soil should be thoroughly wetted at each watering during the active growing season (spring and summer), water when the top 1,5- 2 cm of soil feels dry to the finger. Do not soak the soil during the dormant period. Be careful, excessive watering can make root and/or stem to rots. Make sure there is good air circulation between plants. Good drainage is essential along good moisture retention properties and adequate nutrients availability. Require bright sunlight to grow well. Dormant plants do best at temperatures from 5-10°C (but will tolerate -5° for short periods). The cooler temperatures develop sturdier plants and encourage the formation of flower buds.
Pests: The narrow ribs, the wooly areoles, and the dense spines are an ideal habitat for mealy bugs. Frequent inspection of the plants will prevent them from spreading.
