Hi
Here is a link showing clearly how alternate and opposite leaves appear. Per a previous photo question listed on this site, Poison Ivy leaves are alternate and do not originate directly opposite each other. (see text posted in response on: http://poisonivy.us/view/picqna.html?func=viewQNA&did=1049&wid=486)
Visual Aid for Alternate and Opposite Leaves:

Hope this helps other people like me who need visual aids to help in identifying this invasive stuff. =) |
