Tabasco.

Here's a pic of one of my Tabasco (assumed) chillies. Bushy little fella ain't he?

It looks like an annuum of sorts - the large white flowers and also single flowers at each node are the giveaway.  Tabasco, being a frutescens, has small greenish flowers and multiple flowers at each node.

Here's a pic of the mother from last season if its any help.

^ Have to agree with RobStar.  That second pic is some sort of tabasco or closely related plant.  The first pic is at most a cross with an annuum if you're certain there were no seed mixups... that's not all bad, the pods will probably ripen faster and still taste good.

Seeds were definitely harvested from the mother above and were not mixed up. However there is a very good chance that the mother was cross pollinated with one of four other varieties that surrounded it.
 
The plant in the first picture has very dense growth which was the main reason for posting it. Here are some pics of the same plant closer up:

 

 
The biggest pod it has. Definitely unlike the mother.

 
A brother of the same plant. Different looking pod, and much less dense growth.
