| With all serotinous species that I have seen, some of the trees open their cones at maturity, others at indefinite intervals. |
| This group combines the dehiscent cone of the Lariciones with the wood-anatomy of the serotinous Pines. |
| 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. |
| The serotinous cone is a gradual development, wanting in most species, rare in a few, less or more frequent in others. |
| The persistent cone, the first stage of the serotinous cone, is equally sporadic in the earlier stages of evolution. |
