Set "origin" of polygon for L-System

I'm very new. I'm trying to specify where on a polygon the center of transformations should be, when a polygon is an input to an l-system, as if the polygon were a leaf on a tree. If I use a transform operator to move pivot for translate and pivot for rotation, it does what I expect when rotating a grid. But, in the L-System, it's using the center of the grid rather than the pivot location, I think. I'm probably not understanding something basic. How can I have the l-system transform from somewhere other than the center?

Thanks! That does what I want. I don't understand why, though. I used Match Size with translate alignment position x .5 (the grid is 1x1). I guess the l-system is using the center of the bounding box?
It also works if I edit the "center" of the grid, and then use the grid as input to the l-system. I was looking for that and found pivot. I don't understand pivots or pre-transform, yet. I am having difficulty finding the concepts that examples demonstrate, while I try to learn houdini.
