sepal. Petals lanceolate-oblong or oblanceolate-oblong, 
subacute, more or less oblique, about 4 mm. long, 1-1.2 
mm. wide. Lip small, adnate to the base of the column, 
distinctly shorter than the column, conspicuously clawed, 
up to 2.2 mm. long; claw about 1 mm. or less long, 
gradually merging with the lamina, with a high central 
keel that extends to about the middle of the lamina; 
lamina rhombic-ovate with incurved sides, narrowed to 
a subacute apex, about 1.6 mm. wide when expanded. 
Column long, cylindric, abruptly recurved at the apex, 
about 8.5 mm. or less long at the back, more or less 
clavate. 
This species is allied to Notylia Koehleri Schlitr., which 
has a lip about equaling the petals and much exceeding 
the column.

As noted by my colleague, Dr. L. O. Williams, this 
concept does not represent a member of the genus Dip- 
teranthus Rodr., but is a true Notylia. Therefore, the 
above combination is proposed. 
This species appears to be very closely allied to No- 
tylia boliviensis Schitr., which has also been collected in 
Peru, and is vegetatively nearly inseparable. It differs 
from the latter species, however, in having a lax (not 
dense) raceme with somewhat smaller flowers, in having 
obtuse (not acute nor acuminate) petals, and in having a 
lip which is ovate-suborbicular rather than subquadrate- 
ovate.
