The concept, Trigonidium peruvianum, is represented 
as having subobtuse petals, whereas those of 7". tenue 
are sharply acute. Aside from slight variations in floral 
measurements, there are no other significant differences 
between these species. The tricarinate callus on the lip, 
which is attributed to 7. peruvianum, is doubtless rep- 
resented by three central approximate more or less cal- 
lose-thickened lines shown on the lower portion of the 
lip of 7. tenue. 
It appears entirely reasonable, therefore, to reduce 
T. peruvianum to the earlier 7’. tenue.
