peruviana. Moreover, the several collections of B. Col- 
feyi in the Ames Herbarium from British Guiana (the 
type locality of that species) and from nearby Trinidad 
show lateral sepals which are truly oblong and not in any 
sense spatulate when expanded. Furthermore, the al- 
leged color of the flowers appears to be very similar in 
the two concepts. 
Considerable variation in size of the floral segments is 
shown by specimens of Batemannia Colley: from British 
Giuliana, ‘Trinidad and Brazil. Indeed recent collections 
from Peru exhibit even larger flowers which are often 
more fleshy in consistency. One Peruvian collection, 
Klug 1441, has somewhat narrower petals than usual and 
approximates the form depicted in the Botanical Maga- 
zine t. 8818. 
Since the original spelling of the genus is Batemannia, 
it is in the spirit of modern practice to conserve this spell- 
ing, even considering the fact that the spelling Batemania 
was pointed out as orthographically preferable by End- 
licher in 1886. 
This species appears to be rather widespread through- 
out northern South America, having been recorded from 
British Guiana (type), Trinidad, Brazil and Peru.
