ByOctober they open and the seeds are distributed, the cones remain-ing on the trees until the following spring or summer. 11919°—18—Bull. 604 3 18 BULLETIN 604, U. S. DEPARTMENT OF AGRICULTURE.

INCENSE CEDAR. 19 The seeds, two of which are borne normally at the base of each ofthe two seed-bearing scales, are small, light brown, and attached to acomparatively large wing measuring from three-eighths to one-halfinch in length and from three-sixteenths to one-fourth inch inbreadth. The lightness of the seeds, which weigh about 16,000 to thepound, and their relatively large wings adapt them to wide distribu-tion by the wind. The wings are provided with glands containinga clear, red, pungently odorous resin which renders the seed more orless undesirable to rodents. This and the abundance and small sizeof the seed doubtless do much to insure the perpetuation of thespecies. Incense cedar p
