Note
|
S. micranthum is closely allied to the northern S. angustifolium ("Blue-eyed Grass") and the southern S. chilense, both, of which have much more open perianths and glumaceous spathes of nearly equal valves, and which possibly are no more than subspecifically distinct upon the basis of their seeds.
