Once described as 'Trichocereus damazioi', but apparently virtually identical to 'campos-portoi' . Further research is needed. This specimen is HU330. This form is distinctive in its habit of forming very short segments. Each one actually representing annual growth.
Further research is needed.
My suspicions are that this form may be quite genuine. If anyone has further information, it would be gratefully received. This distinct species is included with the glaziovii complex primarily because current thinking places it here. This species is unlike any other member of the genus in that it will occasionally open its flowers during late afternoon and often close them again by dusk. Furthermore, the opening of the blooms only appears to occur when conditions tempt it to do so.
