Plagiarism in the book "The Genus Turbinicarpus"
by Milan Zachar and Edited by Igor Dráb

This taxa was previously known as Gymnocactus saueri "Preenii".

The original description erroneously gives the type locality as the area of Jaumave, in the state Tamaulipas, México. This plant generally offsets more than the description indicates.

When this taxa was first described, the name was misspelled as pseudomacrohele ie. without the second "c" as was macrochele.

This taxa is either closely related or identical with T. pseudomacrochele var. sphacellatus.

This taxa seems to be fairly variable in body diameter. Cultivated specimens also generally have a larger diameter than that shown in the description.

Most of the plants I have seen have 2-3 "side spines" which are about half the size of the "radial" spine. They are curved sideways towards the body and result in a cross shaped arrangement of the spines.

This is one of the taxa which prefer a bit of shade as they tend to turn reddish and shrivel if kept in full sun.

This plant is capable of producing its off-white flowers when it is little larger than 1cm ø.

In Edward F. Anderson's 1986 revision of the genus Neolloydia (Bradleya 4: 1-28, 1986.) he miss identified this taxon with T. schmiedickeanus ssp. andersonii.

The taxon lilinkeuiduus n.n. is referable here. This name is nothing more than a misspelling of klinkerianus which apparently originated from Arizona, USA and was distributed by various European nurseries. As the exact habitat origin of this plant is unknown, the designation I use for this plant is T. schmiedickeanus ssp. klinkerianus "lilinkeuiduus".

The cheeky sods have even had the nerve to keep the use of the "I"!!

Backeberg's original description is invalid because the type locality was not given and according to the ICBN this is required. The name was later validated by Lechner and Jantschgi in Turbi-Now Issue 4, 1998.

For a long time it was thought that this taxa was a synonym of T. schmiedickeanus ssp. klinkerianus fa. schwarzii, even though they look completely different and come from quite distant localities. The easiest ways to distinguish between them are schwarzii has a pale green epidermis, angled tubercles and white stigma, whereas polaskii has a brownish epidermis, flat, rounded tubercles (it looks like the plant has been inflated with a bicycle pump !) and pink stigma.

The true species is probably extremely rare in cultivation as most of the currently available seed and plants are of T. mandragora ssp. beguinii.

In Bradleya 18, 41-44, 2000, Alessandro Mosco and Carlo Zanovello transfered taxa to their new monotypic genus Lodia.

The citation for this taxa has, in the past, been erroneously given as Kakteen, 25, 1929, when in fact the correct page number is 255.

This taxa was previously known as Gymnocactus beguinii fa. "Sierra de la Paila" and G. beguinii "Canyon Verde" and G. beguinii sp. Lau 1035.

The citation refers to a book and not the Czech cactus journal of the same name.

According to Glass and Foster, this white flowered form is more common than the type. The areoles are noticeably more yellow than in the type, this is the best way of differentiating the two forms when not in flower.
