| Here also appear a new form of fruit, the oblique cone, and a new method of dissemination, the serotinous cone. |
| In the Insignes the cone is oblique, persistent and serotinous, and the spring-shoot is multinodal. |
| Like the persistent cone, the oblique cone finds in association with the serotinous cone a definite reason for existence. |
| Hence all the families of this legion appear to be serotinous, their simple primitive nucleus persisting for a long period. |
| The serotinous cone is a gradual development, wanting in most species, rare in a few, less or more frequent in others. |
| The trees' cones are serotinous, sealed by a resin that is only opened by heat. |
