Turbinicarpus saueri ssp. nelissae"
Date: 1996 November 6
Location: Tamaulipas
At the time, Charles Glass referred to this
undescribed species as sp. or var. nov. "Preenii" (which I then spelled
as "Preemii" for a while). I don't know the origin of this name. However,
in 1998 it was formally described as T. saueri ssp. nelissae
ny Halda and Panarotto.
