Thank you for writing.
There are a couple of resources you could use to identify and locate additional pieces from this plateware collections.
Corning's home goods brands, such as Corelle and Pyrex are now produced and sold by World Kitchen. If the pattern is still being produced, you can find them on their home page: http://www.shopworldkitchen.com/
For patterns that have been discontinued, there are a number of companies that specialize in selling old and new dinnerware. Replacements.com is an example, but there are others who offer similar services. These sites can also be a good resource for identifying patterns. I searched for "corning and tulips" on the site and came up with several examples of plates that look similar to the pattern you described. Once you have identified the pattern and brand, you can search for other sites that sell the pattern.
These resources should get you started on your search, please let us know if we can be of further assistance.
