Indian Corn Cob, Corn Cob Plant, Corncob Euphorbia, Corncob Cactus
Euphorbia mammillaris L. is the correct and accepted scientific name for this species of Euphorbia. It was named and described as such by Carl von Linnaeus in the first edition of Species Plantarum in 1753.
Carl Linnaeus is also credited with naming the Euphorbia genus and describing it in the first edition of Species Plantarum in 1753. Plants of the World Online currently list 1,986 accepted species in the Euphorbia genus (as of 3-2-19 when I am making this page). Those numbers will no doubt change.
I picked up this Euphorbia mammillaris cutting on March 29, 2019. I have had a few other Euphorbia species as companions and we have always gotten along very good. I like the small leaves and there are remnants of its small yellow flowers.

I don’t know a whole lot about tis plant since I just acquired it. I will continue adding more photos and information as time goes by.
