Wild in Guatemala; at ihe fool of the active volcano Xetuch, about 8000 feet 

 obove the sea, near Quezaltenango— Hartweg. 



This curious little alpine plant forms tufls of pseudobulbs and raembranous 

 aheaihs , from among which just peep out tlie tiny colourless flowers, which are not 

 obove ihree lines in diameier, even if spread out. I have not seen the pollen-masses 

 and il roay not belong to this genus.
