The "macrantha" variety has much longer reddish spines with flowers that are reddish orange or yellow that are born near the tops of the stems.

Trichocereus grandiflorus was included into E. huascha and has much shorter reddish spines on top. I don't see any taxonomical distinction between them even though they are different plants. Being the main E. huasha (not variety or cultivar) is reported to have spines over 2 inches long which I also don't see how that differs from the 'rubra' variety.

The 'rubra' variety apparently has ruby-red flowers and might be a synonym of 'rubiflora' variety. It also has very long spines, 1 to 2.5 inches long.
