SCHEDULAE ORCHIDIANAE 
NO. 9 
New or Noteworthy Orchids 
BY 
OAKES AMES 
TN the following pages twenty-two new species are pro- 
posed, and the results of recent studies of tropical orchids 
are set forth. The new species, with the exception of the 
West Indian Pleurothallis archidiaconi, are natives of Costa 
Rica. 
The sequence of genera conforms to the arrangement 
adopted by Pfitzer in Engler and Prantl’s “Die natiirlichen 
Pflanzenfamilien.” 
The illustrations have been prepared from dried speci¬ 
mens, with the exception of Vanilla odorata Presl, of which 
the flower was drawn from material sent in alcohol from 
Ecuador and Epidendrum caligarium Reichb. f., the flowers 
of which were sent in alcohol from Panama. 
Unless otherwise specified the type specimens have been 
deposited in the author’s herbarium. 
Vanilla odorata Presl Rel. Haenk. 1 (1830) 101; 
Klotzsch in Bot. Zeit. 4 (1846) 563; Rolfe in Kew Bull. (1895) 
178; Rolfe in Journ. Linn. Soc. 32 (1896) 471.

“V. foliis lineari-lanceolatis acutis nervosis, capsulis 
lineari-lanceolatis longitudine foliorum.

cans. Folia brevissime petiolata, erecta, lineari-
