There is no record at present of typical Polystachya 
caracasana in the Reichenbach Herbarium. Although 
this concept appears to be very close to P. cerea, of which 
we have seen a drawing of the type in the Lindley Her- 
barium, it seems to differ in having a subcordrate base 
to the lip and a long-petioled base to the leaves. 
Polystachya minor, as described and figured by Faw- 
cett & Rendle, differs from P. cerea only in being a much 
larger plant with a paniculate rather than a racemose in- 
florescence. However, the degree of vegetative size and 
the simple or compound character of the inflorescence is 
of no specific weight in Polystachya, for dwarf racemose 
plants appear in the same collection with large panicu- 
late forms. 
The concept, Polystachya guatemalensis, is represented 
in the Ames Herbarium by an analytical drawing made 
under the supervision of Dr. Schlechter. It is a large 
plant analagous to P. minor, but is described as having 
obtuse sepals, unlike those of P. mimor. However, the 
drawing shows these organs as being acute. The only 
noteworthy difference between these species is that the 
mid-lobe of P. guatemalensis is described and shown as 
subcuneate-quadrate rather than ovate-subquadrate or 
elliptic-ovate as in P. minor. In view of the fact that the
