I bought some orchids on ebay. The grower also sent me this extra
plant (an orchid?) But I don't know what it is. When it come it was
all grey as shown in the photo, but I watered it anyway and it has
grew a kind of green shoot that looks like maybe a new psudo bulb? I
don't know. Anyone have a CLUE what this thing is? It's about 3 in
high (with the pot.)
