How can I tell the difference between peyote varieties?
Updated: Jan 23
One of the things that peyote and cannabis have in common is they both feature varieties with dramatically different chemicals constituents, known as chemotypes.
Broadly speaking, peyote varieties fall into two main categories, northern and southern. With a little practice, it is possible to distinguish between the two by examining the flower, counting the ribs, or observing the growth pattern.
“You can distinguish northern from southern using the rib-count method. Northern forms display an escalating Fibonacci sequence of 5 ribs, then 8 ribs, then 13 ribs. Southern forms can display a rib count of 6,7,9,or 10. .”
If the plant is in flower, that offers more clues. Northern specimens are generally autogamous (self-fertile). They have a larger stigma, are shorter overall, broad and rounded petals with prominent mid-stripe, short and white stigma is pink-tinted (generally), stamens are white reaching the stigma. Their anthers are yellow to orange. Southern specimens are always heterogamous. They have a smaller stigma, are longer overall, sometimes lacking the flower mid-stripe, and their stigma is white (generally).

This map shows that peyote varieties can be divided into northern (blue) and southern (red) categories based on the native range. There is also an intermediate zone (pink) where specimens sometimes display traits from both north and south. Yellow represents the center of each population. Northern forms are centered around Saltillo and Coahuila. The native range includes Chihuahua, Coahuila, Durango, and the top of Nuevo Leon. They are primarily single-headed. Southern forms are centered around Huizache and San Luis Potosi. The native range includes San Luis Potosi, south of Nuevo Leon, Tamaulipas and Zacatecas. They tend to grow clusters of heads

I want to again remind everyone that I am not a doctor, and this is not intended to be medical advice. For those of you who are going to be using peyote and cannabis anyway, I hope that you are inspired to take a more scientific approach. Always talk to your health care professional before attempting any mesearch experiments.
