stachya stenophylla Schltr. may also be referable to the 
variable P. nana, but I have seen no authentic material 
of the former concept. 
The range of Polystachya nana extends trom the West 
Indies (Bahamas, Cuba, Jamaica, Hispaniola, Grenada, 
Trinidad) to British Guiana (type of Stelis foliosa), Sur- 
inam, northern Brazil and Peru (type of A/neyclia nana). 
Galeandra Baueri Lind/. var. piloso-columna 
C. Schweinfirth var. nov. 
Herba carinis duabus brevibus plus minusve arcuatis 
atque columnae superficie anteriore plus minusve longe 
pilosa a specie differt. 
Plant very similar to Galeandra Baueri but distin- 
guished by having a pair of short more or less arcuate 
keels (instead of straight elongate keels) on the disc of 
the lip and especially by having a more or less promi- 
nently pilose anterior surface of the column. 
This form is perhaps referable to Galeandra dives 
Reichb. f) (in Bonpl. 2 (1854) 98), in the description of 
which there is no reference to the column. I have seen 
no record of this concept. G. dives is treated as a syno- 
nym of G. Bauer Lindl. by Cogniaux in Mart. Fl. 
Bras. 8, pt. 4 (1895) 298.
