Hello. 

Very purple cactii sourced with no label, no information.   How is the process to find the name of a species ?  The largest is ~ 6cm x 3cm

 

If you are asking about the process, there are field guides where you go through a kind of flow chart of plant characteristics and arrive at the correct species when you answered all the points. Usually they are writtten for ageographic region, though.

Download the iNaturalist app. Take a picture. It’s really good about telling you what it is, including the scientific name 

Shoot, another skill made obsolete, it seems.

iPhone will do this, though I’m not sure of its veracity. Take a picture, drag the bottom of the photo up. There’s an option to ID plants, if it recognizes a plant.

Good call. I noticed this when it ID’d a pic of a groundhog we got in the front yard a week ago. Wasn’t the scientific name, but I probably could’ve clicked it to learn more 

 

And sure enough: clicking it brought me to the wiki which told me the scientific family

The groundhog (Marmota monax), also known as the woodchuck, is a rodent of the family Sciuridae, belonging to the group of large ground squirrels known as marmots

Comb through Cactiguide.com

The link opens on a best guess candidate species I remember from my cactus collecting days.

The strange colour is obtained through propagation of a random sport. 

Back in the '70s, the only species I recall seeing with this intensity of colour was Gymnocalycium mihanovichii (var. Hibotan), which had so little chlorophyll it had to be grafted onto (typically) a Hylocereus sp. rootstock.

It seems there are more of these options available these days.
