Pleurothallis Schlechteriana Ames nom. nov. 
Pleurothallis costaricensis Schltr. in Beihefte Bot. 
Centralbl. 36, Abt. 2 (1918) 395, non Rolfe. 
Under the name Pleurothallis costaricensis, Rolfe 
described, in 1917, a species collected by Lankester (no. 21). 
The type of Rolfe’s species is missing from the Kew Herba¬ 
rium. In my herbarium there is a specimen kindly placed 
in my possession by Captain Arthur W. Hill, Director of 
the Royal Gardens, Kew, which was prepared from a plant 
cultivated in the orchid houses at Kew. This plant, although 
it no longer bears the collection number, was received from 
Mr. Lankester in 1915, when the type was imported. It 
agrees satisfactorily with the description of P. costaricensis 
Rolfe, although the flowers are orange-yellow rather than 
greenish-yellow, and the lip is rather oblong than pandurate. 
Pleurothallis Schlechteriana is a member of an entirely 
different section of the genus. From records in my her¬ 
barium it is a near ally of P. cardiothallis Reichb. f. and of 
P. acutipetala Schltr.
