A NOMENCLATORIAL TRANSFER

Maxillaria ampliflora C.Schweinfurth nom. nov. 
Camaridium grandifiorum Ames in Proc. Biol. Soc. 
Wash. 84 (December 1921) 149, non C. grandiflorum 
Schltr. in Fedde Repert. Beihefte 9 (September 
1921) 165. 
As recent studies have convinced us that the concepts 
Camaridium and Maxillaria are congeneric, the Central 
American plant described as Camaridium grandiflorum 
Ames should, in our opinion, be referred to the genus 
Maxillaria. The prior use of the combination Maaillaria 
grandiflora by Lindley necessitates a new name. 
This species was originally described from the Prov- 
ince of Chiriqui, Panama, (J7.P. Killip 3565); but a 
fragmentary specimen from San Jer6nimo, Costa Rica 
(M. Valerio 2709) is also reterable to Mavillaria ampli- 
flora. 
Closely allied species are Maaillaria semiorbicularis 
A. & S. and M. planicola C. Schweinfurth nom. nov. 
(Camaridium latifolium Schlechter in Fedde Repert. 
Beihefte 17 (1922) 74, non Maaillaria latifolia Lindl.) 
which grows in low places. M. semiorbicularis differs in 
having a dissimilar lip with relatively large lateral lobes 
and M. planicola differs in having prominent pseudobulbs, 
distinctly petioled leaves and obtuse lateral lobes of the 
lip.
