Unknown type of blackberry bushes

[YumYum]

Can anyone tell what kind of blackberry bush I have just by looking at it or maybe know of a guide to look at to figure out what they are?

It is a thornless variety. I got some plants earlier in the year and they were unknown what type they were. Only one lived. I do have other blackberry bushes that I planted about the same time and I can tell it is not an Arapaho type. I have Navajo plants and I can't really tell any difference, if any yet. Maybe the differences will show more next year.

Here is the blackberry plant in question:

Something weird I just noticed was the leaves don't always have 5 leaves.

I found the following website that may help me narrow down the variety but it will be next year as my bushes aren't really old enough to tell yet.

Now you have me trying to remember if my blackberries go from green to black or from green to red to black! Mine are Kiowas though so I can probably look it up!

Look at the Chester Thornless and see what you think. The leaf shapes run from rounded to pointed but the Chester seems likely.

There are a heck of a lot of sub-species, plus hybrids, plus crosses with other species, I think it comes to well over 1,000 varieties. I remember my brother telling me a friend of his got his PhD classifying them in one area, counting numbers of stamens, Ouch!

Seems to be a lot of variables to make note of. I didn't see the color change type or the number of stamens on that site. Where are those at?
