white pine, Pinus strobus

The state flower for Maine is white pine, and they specify both the cone and tassel. Here's the male tassel. The fertile cone looks very much like a smaller version of the mature cone. The shape of the scales is very much to do with the aerodynamics of pollination. and the inevitability of mathematics. The gaps between scales have evolved to maximize the circulation of wind-borne pollen around the ovaries. The spiral arrangement of the scales is determined by the Fibonacci sequence, in which you start with zero and one, then add the previous two numbers to get the next. 0+1=1, 1+1=2, 1+2=3, 2+3=5, and so on. White pines grow in AL, AR, CT, DE, GA, IA, IL, IN(R), KY, MA, MD, ME, MI, MO, NC, NH, NJ, NY, OH, PA, RI, SC, TN, VA, VT, WI, WV, MB, NB, NF, NS, ON. PE, and QC. Lenawee Co MI, 5/28/15.
