last weekend explored one of the hills in Bau, home to northiana. We were walking up among some loose limestone and in the open found some plants that doesn't look like northiana.Leaves were short,slender with pointing end, lots of brownish/red spots due to the direct sun ( there is no shelter ). One of our group commented a cross between lowland veitchii. There are veitchii around but we have never found on this hill. Yes, Perhaps veitchii pollens blown over from nearby. Another different is the peristome that doesn't display the colors typical of northiana. What do you think?
