“In 1996, Hugo Philips and Johan Pot started the SulcoMania project. It focuses on the cactus genus Sulcorebutia. After the departure of Hugo Johan decided to continue the project alone.
In 1999, Dr. Günter Hentzschel published a recognition key for sulcorebutias (Succulenta 78 (3) 1999, p.138). They would only be able to distinguish themselves from weingartia’s by the funiculi. However, this observation proved to be invalid, leaving no formal morphological differences between the genera.
That is why classical weingartia’s and even Cintia have been included in SulcoMania, but no rebutia’s that can be clearly separated on the basis of their seeds. Though the name Weingartia is older than Sulcorebutia, the name of the project has not been changed.
It is not always possible to distinguish a taxon morphologically from other taxa. SulcoMania is based on a fictitious average plant per taxon. If 75% of the individual plants studied are more similar to this average plant than all other plants in the project, the name is printed bold.
The name is enclosed in quotation marks if there is little agreement with plants from the type locality or if no data have been collected. In the latter case, the choice of the discoverer of the population is often followed.
In SulcoMania names of species and varieties are used at the same level.”
This is a must have for all Sulcorebutia's (or Weingartia’s) enthusiasts.
SulcoMania is published on DVD considering the number of photos (More than 13,000 - plants, flowers, seeds, seedlings). All the most recent descriptions are available ! SulcoMania is a huge database : each plant is illustrated with several colour photographs (on the field or in cultivation), described and located (map). For the searches, the plants are classified by field number or by name. Synonymies are also indicated. It is possible to morphologically compare two plants, generate cladograms… In fact, all you want to know about a specific Sulcorebutia can be found in this DVD. It's really a great great work and regulary updated.
Based on the same principle as SulcoMania, two other CD's are available : DigitoMania of Johan Pot (30 €) et LobiviaMania of Clazien Bouwman (30 €). Both of them can be ordered from Johan Pot.
With CactusData you can compare 1700 different clones of Sulcorebutia and Weingartia.
You select a reference plant and with just a click on a button you can get for example :
a list of plants with the same name;
a list of plants with similar characters (you can indicate the similarity rate that you need);
a list of plants growing within a certain radius (you can indicate the radius you need);
You can compare several plants that you select in the list : in this case the program
Johan Pot is well known in the world of collectors of Sulcos : his field numbers are identified by the letters "JK".
This CD is very interesting because the author relates his Bolivia trips (7 until today).
How to read the story ?
There are two solutions :
1°) You click on the text and you read the full story.
2°) Different maps can be displayed. You will see numbers on the map and if you click on those numbers a photo appears. Some of those photos will lead you to a text section explaining the photo.
You can also display the JK field numbers in the maps (not only Sulcorebutias) and when you click on them a photo of the plant is displayed.
The text is in Dutch, German and English. At the moment (in 2007) the complete story has not yet been translated in English (3 trips on 7).

indicates the similarity rate between those different clones. You can display a graph of the comparison (cladogram) and then the photos of the different clones and the flower section of those plants are shown (see the screen capture here above).
This program is based on 48 criteria's (from the number of ribs and the pistil diameter to the colour of the central spine).
When you compare several plants, clicking on the button "details" will display all data concerning those criteria's.
