The specimen shown is ISI 1417. Also available is HU228, although some specimens I have seen purporting to be of this species, have shown a much closer affinity to the 'microsphaericus' form. Hu228 has lighter spines whilst the 'microsphaericus' form has distinctly darker spines, almost black at the base. Another reference in circulation is HU851. 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.
