Neolloydia conoidea Neolloydia conoidea volt-ampere. matehualensis Neolloydia mandragora Neolloydia matehualensis Neolloydia subterranea Neolloydia subterranea volt-ampere. zaragozae Neolloydia texensis etc. Neolloydia occurs as genus of cacti. A genus is unambiguously obtained in the dry scrub areas of southern Texas (Big Bend) and a Chihuahua Desert of Northeast Mexico.

Taxonomy
A genus was 1st erected by Britton & Rose in 1922 in order to classify 3 uncomfortable species formerly placed in the genus Mammillaria (N. conoidea, North. ceratites, & North. grandiflora). The for metal money was added inside 1923 (N. texensis). However it was non until 1948 that a fifth & final mintage was added by Backeberg (N. matehualensis).

Since so, Neolloydithe hwhen been a dumping ground for coinage from either such diverse genera as Mammillaria, Coryphantha, Escobaria, Echinomastus, Cumarinia, and Thelocactus.

It was non until Glass and Foster (1977) showed that there are very couple of botanic differences between Turbinicarpus and Gymnocactus that the definition of the Neolloydia genus began to take form. Their function was followed higher by John and Říha (1981) and eventually by Anderson in 1986. Eventually it seems that Anderson's function on the Neolloydia complex is okay, a usually accepted learn from.
