NOTES ON TROPICAL AMERICAN ORCHIDS 
BY 
CHARLES SCHWEINFURTH 
AS A RESULT OF studies on the orchids of the Ameri- 
‘an tropics, the following nomenclatorial notes, com- 
ments, amplifications and new varieties have been deemed 
advisable. 
Fuertesiella pterichoides Schlechter in Urban 
Symb. Antill. 7 (1913) 493. 
Cranichis grandiflora Ames & Schweinfurth in Sched. 
Orch. 8 (1925) 8, fig. 2. 
Fuertesiella grandiflora Schlechter in Fedde Repert. 
21 (1925) 331. 
A careful comparison of the type collection of Crani- 
chis grandiflora with an isotype collection of Huertesiella 
pterichoides shows that the two species are synonymous. 
In this collection of Muertesiella pterichoides, one plant 
which is considerably taller than Cranichis grandiflora 
has a leaf about 8.7 cm. long with a petiole about 4.5 
em. long, while another plant which is but slightly taller 
than C. grandiflora has a leaf about 2.3 em. long with a 
petiole about 1.7 em. long. C. grandiflora has a leat al- 
most mid-way between these extremes, the lamina being 
about 3 cm. long with the petiole about 1.5 cm. long. 
The flowers of Cranichis grandiflora appear to be 
slightly larger than those of Muertesiella pterichoides.
