Stelis argentata
 

This flower is quite small, about 3/8" across. But plentiful, this spike has about 20 flowers and there's another 2 spikes a week or two behind this one.
These flowers are fuzzy with little hairs around the edges and although my pictures don't show it, the blooms are slightly transparent with a light source behind them.

Cool, you got the yellow one.

Have you seen the red one? They're really nice.

I have indeed seen a red one. (I did a quick google search after reading your reply.) Very nice.
My camera doesn't bring the colours out quite as I see them in person. I would describe the colour more as a light transparent pink. With a few yellow blotches.

I recently got one of these from Tropical Orchid Farms on Maui - very nice. It bloomed for me about 2 weeks ago - small flowers indeed, but very charming. I am growing it in an itermediate greenhouse with good humidity. It seems very happy!

I love pleuros and Stellis, this is a great one... CONGRATS!!!
