In the vast world of succulent Euphorbia species, there are many forms and shapes. The euphorbia.de web site is the most complete reference we've found for identifying the many different specie. We will only catorize some of the forms that we have had hands on experience with here. This section does not cover caudex forming Euphorbia. Those are covered here. Euphorbia plants have one thing in common, they excrete a white liquid when the skin is broken called latex. This latex is a repellent to protect the plant against predators. Depending on the species, the latex can be very poisonous, or be a nasty irritant to the eyes and sinuses. Be careful when handling Euphorbia plants and always wash your hands after being exposed to the latex.
A short List of Succulent Euphorbia Plants
Type 1 - Thick Columnar Stems that Form Clumps Like Hedgehog Cactus

Type 2 - Many Thin Straw-like Stems
This type has thin succulent smooth stems forming a low growing shrub. The stems can be upright or drooping.

Type 4 - Euphorbia with Relatively Small Succulent Stems that have a Ball or Cylinder Shape.
The typical species here is Euphorbia obesa. A single stem forms a fat ball shape with no leaves or other stems. It will eventaully become cylindrical. In the case of E. meloformis, new globular stems form on the ribs of older stems until a mound of 50 or heads are clustered together.
