The type specimen Wo, 20012 was collected September 15, 1936, in a woods 
at Pine Knot, the vacation residence of ivk*. and Mps, J, L, Hooks, of Beaumont, 
Texas, This place is about six miles south of Silsbee, and is in ^%rdin County, 
As the plants were growing under a big beech tree where the ground was littered 
with dead foliage, while other herbaceous plants were not present, it was con¬ 
sidered that they were parasitic on the roots of that tree. This particular 
species has not been seen elsewhere, but as many as fifteen or twenty scattered 
plants were seen here. At time collection was made it was not known that this was 
an undescribed species.
