Descriptions not appearing in my Blogroll for a page template

I’m currently working on this page of winery links and my issue is that while the links display just fine. I thought by default, the descriptions would show up as well. And they don’t. Do I need to add this to my PHP tag?

Here’s the code I’m currently using:
<?php wp_list_bookmarks('title_li=&orderby=name&order=ASC&categorize=0&title_before=<h2>&title_after=<h2>'); ?>

Any help or assistance would be great.
