Gardeners' Notes:

Positive oldmudhouse On Jul 26, 2007, oldmudhouse from Las Cruces, NM (Zone 8a) wrote:

As noted above, a previous name for this plant was Lobivia arachnacantha var. torrecillasensis (Lobivia being an anagram of Bolivia.) The subspecies name "arachnacantha" is derived from the latin “arachne”, meaning “like a spider or spider’s web”. That's a good description of the spines.

I’ve seen it described as a good beginner cactus, and it will remain small in size. In spite of its size, this plant has a bold bloom!

Neutral Xenomorf On Jan 20, 2005, Xenomorf from Valley of the Sun, AZ (Zone 9b) wrote:

There are four subspecies of Echinopsis ancistrophora. Flowers are unscented.
Subsp. 'ancistrophora' has varied colored blooms from white to sometimes a hint of pink to deep red, native to south of Salta, Argentina north to across the border into southern Bolivia.
Subsp. 'arachnacantha' is smaller and has yellow to yellow-orange blooms, native a little farther north into Samaipata, Santa Cruz, Bolivia.
Subsp. 'cardenasiana' has violet-pink to red blooms and is native to Tarija, Bolivia.
Subsp. 'pojoensis' is a larger plant with reddish blooms and is native to Pojo, Cochabamba, Bolivia.

This is the variety of the 'arachnacantha' subspecies that has orange-red blooms.

This variety is a variety of "Echinopsis ancistrophora subsp. arachnacantha"
