While some of the adult forms of Cupressineae, as Juniperus communis, retain the habit of spreading needles, others develop concrescent leaves upon their adult shoots, that is, leaves whose adaxial faces have become organically connected with the adjacent stem surface, so that they appear as green scales. In such cases, the juvenile form, with its spreading
