The persistent cone, the first stage of the serotinous cone, is equally sporadic in the earlier stages of evolution.
The third group, the Insignes, contains the serotinous species.
In the Insignes the cone is oblique, persistent and serotinous, and the spring-shoot is multinodal.
Cones tenaciously persistent, serotinous in various degrees.
Like the persistent cone, the oblique cone finds in association with the serotinous cone a definite reason for existence.
The serotinous habit is more pronounced in this than in any other species.
It is one of the associated six timber-Pines of the Southern States and the only one of them with serotinous cones.
Hence all the families of this legion appear to be serotinous, their simple primitive nucleus persisting for a long period.
With all serotinous species that I have seen, some of the trees open their cones at maturity, others at indefinite intervals.
But with the serotinous cones (radiata, attenuata), the advantages of this form become apparent.
"late," 1590s, from French sérotine, from Latin serotinus "that which comes late; that which happens in the evening," from sero, adverb of serus "late" (see soiree). Also as a noun, a type of small, brown bat, from 1771. Related: serotinous, in botany (1880) "appearing later in the season than usual."
