Google's results are based wholly* on their crawls. So the most answer to that question is, No.
But, google seeds it's results with their adopted form of the ODP (dmoz.org). Google also seems to take particular interest in Yahoo's directory(or, at least,did before the recent yahoo/google adjustments).
I do not know of any other notable input stream.
Google's website specifily mentions ODP/dmoz, and no one else.
* Some users have reported odp/dmoz descriptions appearing for some searches. But, overall this statement is true.
