Kathy, I suspect it may be one of the many of that type that is not positively identified yet. Looking through this site could take some time and they show many unidentified plants, maybe you have already researched this site. http://pleurothallids.com/inde...
Platystele umbellata flowers frequently throughout the year, especially during the indoor season. The plant is loaded right now with little Raspberries and buds.
