Pelecyphora  strobiliformis
(Syn: Encephalocarpus stobiliformis)

CACTUSPEDIA       

 


Encephalocarpus (Pelecyphora) strobiliformis
A very slow growing, choice Mexican species, commonly called
the "Pinecone Cactus" for its resemblance to a pine cone.
 

Etymology: The generic name comes from the Greek en (in), kephale (head), and karpos (fruit), because first the flowers and then the fruit appear at the apex of the stem. The specific name refers to the shape of its tubercles, which are reminiscent of the scales on the strobilus -- or cone -- of a conifer.

Description: Slow-growing geophytic succulent, with solitary or multiple stems barely rising above ground level.
Stem: Spherical to flattened globose, greenish to yellowish-green, somewhat resembling a pine cone and vaguely remin
iscent of  Ariocarpus, 2-4 cm tall, 4 to 6 cm in diameter (or more, in cultivation).
Tubercles: Spirally arranged overlapping.
 They are scale-like, imbricated, and closely applied to each other, flat and convex on the inside and carinate on the outside.  The base is woolly.
Areoles and spines: Dimorphic, with the spines-producing portion on the outer part and
the flower-producing portion at the base of the tubercle. Small, oval, woolly on the new growth in the inner portion of the pointed tubercles apex. While the new growth continues, these areoles produce a few short, more or less pectinate spines. With age, the areoles disappear and the oldest tubercles have a bare, blunter apex.
Root: Large, spindle shaped, compressed taproot.
Flowers: Borne at the base of young tubercles near the top of the plant, diurnal, bell-shaped or funnelform, brilliant, pink to reddish-purple, about 3 cm long, with greenish outer segments and incised or curly inner segments.

Although adult specimens of Encephalocarpus strobiliformis bear scale-like tubercles, which are very different from the laterally compressed tubercles of Pelecyphora aselliformis, all the other characteristics clearly show that they are congeneric, while a third species, Pelecyphora valdeziana, does not seem to clearly belong to this genus, and it is now brought into synonymy with Turbinicarpus.


Cultivation:
It’s a fairly easy species to cultivate, but very slow-growing.  It needs a very well drained soil, and requires strong sun to part sun to develop good spinal growth.  Waterings should be rather infrequent, to keep the plant compact and avoid it becoming excessively elongated and unnatural in appearance.  Keep dry in winter or when night-time temperatures remain below 10° C.  It is hardy to -4°C for a short period.  Assure good ventilation.

Propagation: Old plants put forth basal shoots, but growth is slow;. Propagation is mainly by seed.

Family: Cactaceae (Cactus Family)

Scientific Name: Pelecyphora strobiliformis (Werdermann) Frič & Schelle ex Kreuzinger
Published in: Kreuzlnger, Verzeichnis 9 (1935)

Origin: Mexico (Chihuahuan desert - Nuevo León, San Luis Potosí, Tamaulipas)

Conservation status: Listed in CITES appendix I

Synonyms:

  • Encephalocarpus strobiliformis (Werdermann) A. Berger
    Published in: Kakteen 332 (1929)
  •  Ariocarpus strobiliformis Werderm.
    Published in: Zeits. Sukk. 3:126 (1927


Common names: Peyote, peyotillo,  Pinecone Cactus

 

 

 

 

The arrangement of the tubercles resembles a pine-cone, which is what is meant by the specific name 'strobiliformis'.
