The seeds of this species seem to germinate very readily and without needing too much warmth, I sowed a pack of 20 seeds and 19 have germinated, other cactus seeds I sowed at the same time have had nowhere near this germination rate.

Here are more synonyms of this plant, some of which at some time in the future *might* become a variety, cultivar, subspecies or forma of the species: Eriosyce subgibbosa var. subgibbosa, Eriosyce subgibbosa subsp. subgibbosa, Hildmannia rostrata, Neochilenia rostrata, Neoporteria subgibbosa var. microsperma, Neoporteria microsperma, Chilenia castaneoides, Neoporteria subgibbosa, Euporteria subcylindrica, Chilenia subcylindrica, Echinocactus castaneoides, Neoporteria castaneoides, Echinocactus subgibbosus & Chilenia rostrata.

There are 7 types of Eriosyce subgibbosa. Here are some comparisons between them.
The "subgibbosa" variety has more elongated stems with 8 to 30 thin radial spines per areole.
The "castanea" variety has thin radial spines per areole and globose stems that will sometimes offset. The flowers can get up to 2.5 inches long.
The "litoralis" variety has from 30 to 40 hairlike radial spines per areole.
The "clavata" variety has from 11 to 13 thick radial spines per areole and slender stems.
The "nigrihorrida" variety has dark colored radial spines and globose stems most of the time.
The "vallenarensis" variety has from 9 to 24 thin & straight radial spine per areole and slender stems.
The "wagenknechtii" variety has smaller flowers than the other varieties at about 1.2 inches wide.
All varieties are very prone to root rot and grow solitary stems except the "castanea" variety.

The full name of this plant is "Eriosyce subgibbosa subsp. subgibbosa var. subgibbosa"
