the following reasons. Scaphyglottis parviflora is de- 
scribed and illustrated as usually having bifoliate pseu- 
dobulbs and a lip which terminates in an oblong apical 
lobe that appears to be distinctly smaller than the lateral 
lobes. On the other hand, Ornithidium vestitum, which 
was described by Swartz as Mpidendrum vestitum, is 
noted by Fawcett & Rendle (FI. Jam. 1 (1910) 122, 123) 
as having unifoliate pseudobulbs and a mid-lobe of the 
lip which is ovate and distinctly larger than the lateral 
lobes—a diagnosis made presumably after examining 
Swartz’ type. Moreover, all of the other material refer- 
red to Ornithidium vestitum (from Central America and 
Peru) shows the same unifoliate pseudobulbs and a rela- 
tively large ovate mid-lobe of the lip. 
It seems to be preferable, therefore, to follow Fawcett 
& Rendle’s interpretation of Ornithidium vestitum and to 
consider this species as always having unifoliate pseudo- 
bulbs and a relatively large ovate mid-lobe of the lip. 
Following this interpretation, [ am regarding Scaphy- 
glottis parviflora as a variety of Ornithidium vestitum, and 
have made the proper varietal combination under Max- 
illaria.

T'wo isotypes of this species (Weberbauer 6273) in the 
Gray Herbarium and in the Herbarium of the Field Mu- 
seum show certain disparities from the description. 
The pseudobulbs are ellipsoid to pyriform-cylindric, 
rather than ovate, and up to 8 (not 2.5) em. long. The 
leaves are up to 9 (not 8) em. long. The peduncles bear 
sometimes as many as 15 (not 8-9) sheaths. The sepals 
are oblong-lanceolate and complicate-acute (not narrowly 
ovate-triangular and long-acuminate) and they are about 
1.6 (not 2) em. long. The petals are elliptic-linear (not
