According to Morren the Auellia here figured was intro- 
duced from Brazil in 1875 by Messrs. Jacob-Makoy of Litge 
and was named &. Devosiana in their catalogue of 1876 in 
compliment to Mr..A. Devos, then in charge of the botanical 
collections of the University of Liege. Morren, with some 
reason, compares it with #. picta, a plant of rather doubtful 
status figured by Loddige in 1828, without analysis or 
description, at t. 1448 of the Botanical Cabinet. Lindau has 
treated FR. Devosiana as identical with R. Schaueriana, a 
view which it is not convenient from the horticultural stand- 
Novemser, 1911.
