Here are a couple of illos.
Time is still short, maybe more this evening
a progymnosperm: http://www.science.siu.edu/plant-biology/PLB117/JPEGs%20CD/1033.JPG
A seed fern with the seeds http://www.science.siu.edu/plant-biology/PLB117/JPEGs%20CD/1034.JPG
It's easy to see how the sporangis on the progymnosperms became cones isn't it?
Nice pictures.
Have you had any thanks yet from ModernDayCato for your efforts on the seed question front?
