Star Grass, Star Rush, White Topped Sedge

Dichromena colorata

Description:

This is a grass that was growing in a lawn near Orocovis, Puerto Rico. The striking feature is the way two triplets of grass blades radiate from the seed cluster and are colorless right next to the seeds only, but are regular green out away from the seeds. Basically, it devised a pseudo-flower using regular blades.

Habitat:

This is from a residential lawn in central tropical high elevation Puerto Rico. Conditions are moist and warm. Being in a lawn, it has a pretty good chance of being non-native, I think.

I suggest that you change the name in Rhynchospora colorata. The other name is a synomym but outdated.

Actual name is Rhynchospora colorata according to EOL, not Dichromena which is a synonym.

It is one of the sedges. Maybe even the same one we have in Oregon that is declared an invasive species. http://en.wikipedia.org/wiki/Cyperaceae

Cyperaceae, Rhynchospora colorata. I found this one also in Costa Rica.

That is a fascinating way to make a faux-flower.
