dwarf hair grass

Hey all,

Recently (about 6 weeks ago) I got a pot of what is called "dwarf hair 
grass".  It is very fine grass, about the same thickness as "bermuda 
grass to the southerners of the list, and only grows 1 1/2" (3 cm) high.  
It is growing really well in my tanks after a brief lag (tank is 20 
high, very soft water, 1 pearl gourami, snails, 56 watts of compact 
flourescent lighting).  What i am wondering is does anyone know the 
scientific name of this little cutie :)
