Got Genus
Sick Species
Juglans is the genus; the second name is the species (it in lower case).Members of a species may inter- breed (think dogs)and you can get varieties or breeds.Generally, different species cannot inter-breed or at least not successfully (think mules which are a cross of a horse Equus caballus and a donkey which is the domesticated version of Equus asinus)You will note that they are of the same genus, but different species and although they may breed the off-spring are almost always sterile in their mating.Grafting is another case as one species(the stem) may be attached to another root of a different species. Claro and Black are of the same genus (Juglans), but are different species.
