  Notocactus sellowii
(Syn: Wigginsia sellowii )
CACTUSPEDIA       

 


This species is quite variable, and now includes many forms (previously considered independent species) 
 

Description: Usually solitary.
Stem: Bright or dark green, globose to short cylindrical, up to 20 cm tall, 15 cm in diameter. The apex is depressed and filled with whitish-grey wool.
Ribs: About 12 to 22, at maturity well marked and sharp, with scarcely prominent chinned tubercles. The crest of the ribs typically turns a purple red colour in full sun.
Areoles: Well spaced, woolly, recessed, 15-20 mm in diameter.
Radial spines: 4 to 10 (-12), yellowish, sturdy, about 20 mm long, curved down or backward.
Central spines: 0 or 1, slightly heavier but not very different from the the radials.
Flowers: Lemon yellow with glossy petals (sometime shaded with pink), up to about 4-5 cm in diameter, and standing near the top, decorated with about 8 to 10 red pistil lobes which emphasize the yellow of the petals. The buds are tomentose.
Blooming season: They bloom annually around July.
Fruits: Fleshy reddish to purple, about 10 mm long.
Seeds: 1 mm, long, black.
Remarks:
When the plants become older they look quite different from the juvenile forms, and this is evident when we can observe a seedling growing next to an older plant - the younger plant is smoother and the older plants have ribs and tubercles - one would almost think they were different species.
 


 

 

Cultivation: It is easy to grow. They like a warm, bright location, and do great in partial shade (avoid full sun).  They need good drainage, and prefer a neutral to slightly acidic compost with plenty of extra grit.  Water and feed during the summer.  Best if watered with rain water.  Keep above 0°C and rather dry in winter.  It rots easily if the substrate is wet and cold, and tends to lose its roots in winter.

Propagation: Seeds
 


 
The flowers are lemon yellow with glossy petals, the stigma (purple) with about 8 to 10 red lobes, emphasize the yellow of the petals.

Family: Cactaceae (Cactus Family)

Conservation status: Listed in CITES Appendix II

Scientific name: Notocacts sellowii (Link et Otto) Theunissen
Published in: Succulenta 60 (6):140-142, 1981.

Nowadays regarded as: Parodia sellowii (Link & Otto) D.R. Hunt1997

Origin:   Is native to southern Brazil (Rivera, Lavalleja, Treinta y Tres, Artigas, Cerro Largo, Maldonado), Uruguay and North Argentina grasslands.

Etymology: The plant was named after Friedrich Sellow, a 19th century explorer who collected several south American species of cacti.

Synonyms

  • Echinocactus sellowii Link & Otto

  • Malacocarpus sellowii (Link & Otto) Britton & Rose 1922
  • Wigginsia sellowii (Link & Otto) F. Ritter 1979
  • Notocactus tephracanthus (Link & Otto) Krainz 1966
  • Echinocactus tephracanthus

Notes: All species of genera Notocactus, Wigginsia and Malacocarpus have recently been transferred to genus Parodia, so the names of several plants previously accepted are now all synonyms of Parodia sellowii.
