Mesquite are know for easily become hybrid. This is mentioned since a Mesquite you find may not fit into an exact specification due to it being a hybrid of more then one type of Mesquite.

is this common in other types of trees, i can understand if a nursery makes hybird trees, but mesquite seems to do it in the "wild".

any other trees fit the hybird wild catagory????///:confused:
 
I know there is one hybrid in Oaks - the new tree is called a "Oracle Oak". It is a cross between a interior live oak and a black oak. I know this tree occurs in California. I believe there are other hybrids but they are not as well known as the Oracle Oak.

Could it be that Mesquite and perhaps others adapt to the specific growing conditions of where they are trying to survive ?
 
East Palatka Holly

American and dahoon hollies. below is from the U of Arkansas

East Palatka Holly was selected from the wild about 1926 near the community of East Palatka, Florida, by H. H. Hume, a Florida horticulturist who went on to become Dean of Agriculture at the University of Florida. The tree shows intermediate characteristics between its two parents, the tree form American holly (Ilex opaca) and the usually more shrubby Dahoon holly (I. cassine). While these two species share considerable overlapping range, the former species tends to have a more northern distribution while the latter is restricted to the Gulf Coastal plains in the southeastern states. Because hollies are insect pollinated and because they exist as either male or female plants, the potential for cross-species hybridization is high when they occur in the same area.

The East Palatka trees that are found in the nursery trade are all grown from cuttings and are thus all alike. If seeds are collected from East Palatka and planted, the resulting seedlings will be extremely variable and show a range of characteristics. Some of these seedling plants will look like the American holly parent, some like the Dahoon parent and numerous intermediate forms. Because these hybrids occur often enough in nature botanists have created the hybrid genus I. x attenuata to accommodate all of these intermediate forms.
 
Mike,
I can not tell you about other hybrids - but the oracle oak happens in the wild. I have been shown one by a biologist. Not hard to believe. Just a matter of chance I would think.

Oak Hybrids

Hugh and Mike, and others: I attended a meeting a while back of the local chapter of something like "Florida Botanical Society." The speaker was a professor of horticulture at FSU. Some salient points: There are about 400 species of oak worldwide, and at least 25 in Florida alone. Oak propagates by airborne pollination, and anything can happen. Seems to have all the discipline of a fratority toga party.

I've been trying to find out about a Poplar tree I had in my yard and this thread might be the place to have some questions answered or direct me where to find some.

A 60' Poplar in side yard, serious surface roots (some 4" above ground), about 75 sprouts came up from roots, in 3 days they'd be 6" high and could not be snapped or pulled, had to be cut off. A landscaper and a horticulturist said "it's a hybrid, you should get it out of your yard". They said it's a forest tree, trying to make its own forest, loved living in the open yard but would eventurally choke out other trees and shrubs. This tree must have been 30 yrs. at least. As you can tell by past tense used, it's down and root ground up but I'm interested in learning about it.

I did a lot of googling before deciding to have it cut down but didn't find anything so took those guys' advice.

Sorry I should have mentioned that the original quote about the Mesquite was written by me on my AZ Wood ID Wiki. I was trying to say I have no idea what "easily" really means as far as numbers and percentages. I put the quote on the site after doing some research when the only example we could find of Chilean Mesquite in local arboreums and nature walks was listed as a hybrid.

I would have to assume that it is harder for hybrids to bread then trees of the same species or else it seems like hybrids would take over in the wild.

I would also assume how easily tree in different specis breed with each other has a relation to how closely realated they are. The three types of mesquite we see a lot in AZ have very similiar characteristics as far as Bark, Leaves and seed pods. I would assume they would have better chances of cross breading then lets say then the Acacia's that we have locally that have very different characteristics.
I am by no means a tree expert thought, just rambleing.
