The generic name is in Greek and if translated to English, it roughly means southern cactus, as they are found in Southern America between Brazil, northern Argentina and Paraguay. Their shape goes from dwarf globular to columnar types and they can be either solitary to clustered. The flowers come from close to the centre of the cactus and forms funnel-shape with the colours being yellow to magenta.
Notocactus magnificus comes from Brazil and other countries near it. The blue-green cacti has many angled ribs with slender yellow spines. Mine has clustered, however that is not always the case. Up to now I have not seen the yellow flowers and from what I gather, if I did see them they will be large.
Notocactus ottonis is commonly found and has a number of varieties. As seen, they cluster and their flowers are yellow.
As once was typed here, I was unsure of its species, but someone at the Chelmsford branch of British Cactus & Succulent Society (BCSS) told me it was Notocactus scopa. I have recently taken more pictures of it as the flowers are fanastic. It you could not see it, the petals are yellow and maroon anthers.
