Asian Pear Varieties... just a sampling

I recently wrote an article about Asian Pears. Being that I am just barely familiar with this tree, other than an occasional taste of unknown varieties, I thought I would find some information about a few of the varieties that are out there. Included in this list of 25 are the most common, popular, flavorful varieties as well as a few traditional ones and brand new ones. I tried to list them in roughly the order that they ripen. 

As always, this website is about me gathering information so that I can go back and reference it as I need. There are some areas of missing information that I just couldn't find in a reasonable amount of time. If you have a link to a site that provides any of the missing information in my listings, please feel free to post a comment. So without further ado...
